Welcome to the December issue of Furnaces International.

I’m sure I’m not the only one wondering where this year has gone?! This is our final magazine to publish in 2021 and it also seems that it is the biggest issue of the year so far!

Our new Editorial Assistant, Zahra, has made herself at home and has been giving Furnaces International all of the attention it deserves - hopefully you’ll notice this in this issue with heaps of new content, news, features and outlooks from across the furnace sector.

2021 was also a year of firsts as we launched the Future of Furnaces online event back in September, with the help of BIFCA. It was a great event to bring the industry together and discuss the hot topics (excuse the pun) while we were all still unsure about travel. We hope next year will mean we can all meet in person and we would love your thoughts on where and when we should look to host a live version of this event. Answers on a postcard, please!

This issue also ends on a high, as it includes the Annual Buyers Guide, which is the essential guide to furnace manufacturers, and suppliers of furnace equipment and services to the industrial heating/process industry.

Providing comprehensive company listings, product information and key contact details, the guide can be found at the end of this issue. You’re also welcome to get in touch and send us your details if you have missed out on a listing this year.

As always, I hope you enjoy this issue and we will be back in March 2022, with a new look and even more content.

From all of us here, I wish you a very Merry Christmas and a healthy and Happy New Year.

Future of Furnaces

The state of play with certification o

By John Showell* Following up on the presentation on UKCA marking regulations by my colleague Mr. Mark Lindsay** during the highly successful and well-attended ‘Future of Furnaces’ online event (14th – 15th September) held by Furnaces International magazine, we take the opportunity the put a little more ‘flesh on the bones’ regarding the key points of the presentation.

We’ll expand on some key points in order to capture the state of play as we come towards the end of 2021 and a somewhat tumultuous and turbulent pre and post-Brexit period as things stand.

While Brexit-related uncertainties in the regulatory space seem to be a little less widespread now, the road ahead still has ample scope to branch off in different directions when comparing UK and EU regulations. We are starting to see some divergence in product regulations between the UK and EU e.g. with recent EU REACH substances of very high concern list expansion not being adopted into UK REACH regulations, but for now little or no divergence yet in the Machinery Directive area.

Brexit – A recap � The UK left the European Union on

the 31st December 2020 � The UKCA (UK Conformity Assessed) mark is the UK certification mark to demonstrate compliance with UK product certification regulations. � The UKNI mark is placed on products sold in Northern Ireland that require a mandatory third-party approval process and is done by a UK Approved Body. UKNI mark would always be accompanied by the CE mark, it’s not used on its own. � The UK originally provided a one year implementation period for manufacturers; however this was extended by another year due to issues with availability of UK Approved Bodies where a third-party certification process was mandated. As of 1st January 2023, it will be mandatory for products /

equipment to be marked with the UKCA mark. � Products already placed on the UK market before 31st December 2022 do not need to have the UKCA mark. The CE mark is adequate – but note that this is based on no divergence between relevant GB and EU regulations during this period.

The definition of ‘already placed on the market’ does not have to be a movement of a physical product but can be when the order was placed and paid for.

Legislation Comparison � The legislation and requirements related to UKCA marking are very similar to CE marking requirements. � The Machinery Directive 2006/42/ EC was already implemented into UK law as the supply of machinery (Safety) Regulation 2008. � The EU Brexit regulations essentially

Ground Rules � UKCA mark can be applied by the self-certification process where no mandatory third party involvement is required as part of the conformity assessment procedure. � Furnaces covered by BIFCA (British Industrial Furnace Constructors Association) are typically CE marked under the EU Machinery Directive 2006/42/EC utilising the EN746 series of standards. Transition to UKCA marking is a reasonably straightforward process at the moment and continues to use the EN746 series of standards (and others) but careful attention to detail must be taken to avoid regulatory non-compliances when placing on the market in GB, Northern Ireland and the EU. A summary flowchart of the UKCA marking process

of furnaces in the UK and EU changes the terminology listed in each of the regulations i.e. � EU Directives to UK Statutory Instruments � EU Official Journal to UK Designated Standards � EU Notified Body to UK Approved Body Table 1 gives more details on relevant legislation Certification mark summary - UK, Northern Ireland and the EU

There are published guide documents explaining how to apply the Supply of Machinery (Safety) Regulations 20081 – one for GB and the other for NI (Northern Ireland2).

There are special provisions for placing furnaces and related equipment on the NI market and the guide documents should be consulted. Note that if the manufacturer chooses to (or must) have the equipment assessed by a third-party that is GB based i.e. a UK Approved Body, the UKNI mark should be placed on the equipment in addition to the CE mark (since EU regulations continue to apply in NI while the Northern Ireland Protocol

Note – for NI market, the UKNI logo should not be included for self-certification processes nor for third-party certifications carried out by EU Notified Bodies.

is in place).

At the time of writing (16th Nov 21), the webpage https://www.gov.uk/ government/publications/supply-ofmachinery-safety-regulations-2008 has just been updated to clarify product labelling requirements reflecting the extension of the transition period for UKCA marking and also to refer to the EU Market Surveillance Regulation (MSR) 2019/1019 which is now in force in Northern Ireland.

A particular point to note is that

a company in GB wishing to place equipment onto the NI market will need to appoint an economic operator to fulfil certain legal duties on their behalf.

An economic operator (an authorised representative, importer or fulfilment service) acting on behalf of a GB company can only be located in NI or the EU. The requirements of the EU MSR will apply and a mandate agreement would be needed for example between equipment exporter located in GB and their chosen economic operator such as authorised

representative located in NI or the EU. The representative’s name and address will need to go on the equipment and declaration of conformity and this will be the point of contact for the NI authorities e.g. in case of questions on compliance status of the furnace.

� Check and review the applied EN 746 standards and any other standards pertaining to your equipment / system.

If any further evaluation or testing is required then complete this, document it, and place it in the Technical File.

Review of steps to take for applying the UKCA mark

� Once the Technical File is complete for the UK you will then need to create a new UK Declaration of Conformity referencing the UK Statutory Instruments and UK Designated Standards. This will need to be signed by the nominated Responsible Person (see definitions in the Supply of Machinery (Safety) Regulations 2008 and related guide document). The EU market requires its own Declaration of Conformity of course, referring to the relevant EU CE marking Directives and related harmonised standards from the relevant EU Official Journal.

What you will need to do � The first thing to do will be to ensure your product regulatory Technical File is up to date and adequate for UKCA compliance. Consult the Supply of Machinery (Safety) Regulations 2008 and the associated guide document. You should refer to the Machinery Directive 2006/42/EC as per the references the Supply of Machinery (Safety) Regulations 2008 and the associated GB guide document (referring to the NI one as well if placing in the NI market).

� An NI or EU-based authorised representative (or importer or fulfilment service) needs to be selected and appointed if placing on the market in NI. An EU economic operator such as an authorised representative for placing on the market in the EU.

� Once you’ve checked all is completed satisfactorily (using a Thirdparty if required), you can apply the UKCA mark to the product. As per Supply of Machinery (Safety) Regulations 2008 you become the Responsible Person as defined in the regulations and take on the associated legal responsibilities. � The regulations apply to relevant safety components and incomplete equipment, not only to fully completed furnaces. �

AMETEK Land: Future of Furnaces

By Neil Simpson* Optical pyrometers have been the temperature measurement instrument of choice for high-temperature combustion processes for more than a century. In many of these processes, temperatures are taken using an optical pyrometer at least once per shift, and sometimes every 20 minutes on a regenerative furnace.

Whenever a process-related problem occurs, a portable pyrometer such as the industry-standard AMETEK Land Cyclops

L is used to check temperatures at critical points in the furnace or kiln. Thirty years ago, when a 2D model-based steel reheat control system was commissioned, there was only one fixed location pyrometer on a furnace.

AMETEK Land developed the Near Infrared Borescope (NIR-B) about ten years ago, and its first NIR-B installation took place in a metals application in 2012, with the first glass furnace installation the

following year. By 2021, more than 100 NIR-Bs were installed in the glass industry alone, with some furnaces using two thermal imagers.

The focus on decarbonisation has also led to thermal surveys dealing with aluminium reverb and cement applications.

The instrument initially measured 324,000 optical temperatures continuously in the furnace. For ease

of display, the temperatures generate a visual, thermal image of the furnace, often confused as simply a CCTV image.

It now displays up to three million fully radiometric calibrated camera pixels in the temperature range from 600 to 1800 °C (1112 to 3272 °F) – a development of technical significance for energyintensive heavy industries like steel, non-ferrous and glass production. There

are lower temperature ranged devices available.

When analysing the massive amounts of furnace temperature data captured by the NIR-B, it is worth looking to other professions, such as accountants who use financial models and variance to budget as a means of highlighting differences.

What has changed in the process?

In-furnace thermal imaging enables

the validation of computational fluid dynamic (CFD) models, and supports predictive control.

The use of alarms for variance to design, set point, and previous minute/hour/day/ week/month improves quality and yield which reduces waste – this is the first step to decarbonisation. The second is the optimisation and reduction of specific energy. The third is the optimisation

CASE STUDY: STEEL REHEAT FURNACE For this thermal survey, an NIR-B thermal imaging system was used, and a chain and pulley system to support the camera during the survey. This is very useful to take the weight of the system without the need for any extra support. The front of the camera can rest in the peephole, while the chain holds the rear of the watercooled jacket.

It is best to rest the probe on some insulation rather than the peep site itself, as this will prevent any localised heating of the probe.

This is the initial view of the steel reheat furnace using the auto temperature range (Figure 1). Although it looks like a visual image, it is, in fact, temperature data that is used to generate an image.

By reducing the temperature range manually, we can increase the contrast and resolution (Figure 2). This means we

can now see the two flames on the top fire and start to see the impact of the walking beam cooling skids. We can also identify the hottest flame in the lower zone.

Depending on the process, a monochrome image can often provide the best contrast for viewing the process, and the best view of the refractory (Figure 3).

Next, we reduced the band to just 186 °C, allowing us to see detail on the roof (Figure 4). There is a small discolouration underneath one of the burners. The root of the flame is also now visible – this is some of the natural gas being burned at this point.

Now we move into the negative image, where the dark area is hot, and the white is cold (Figure 5). This provides a different contrast to get an impression of furnace conditions. The peephole on the other side of the furnace is clearly visible, and it

appears there may be some deflection of the billet.

The next image shows the first thermal palette, which is one of the soft transition palettes (Figure 6). You can immediately see that some flames are significantly hotter, creating a risk of generating higher thermal NOx. For the first time, we can also see flames in the downstream zone.

With the 62 colour isotherms palette, and the 186 °C temperature range band selected earlier, each colour corresponds to 3 °C. It allows a greater amount of detail to be picked up (Figure 7).

Returning to the monochrome image, we can bring in some 10 °C isotherms, so 1180 to 1190 °C is blue, while 1220 to 1230 °C is red (Figure 8). This immediately identifies which two flames are the hottest.

Next, we dropped the isotherms by

Future of Furnaces

Figure 11

Figure 12

Figure 15 second, with 324,000 optical pyrometer readings per frame – a significant amount of thermal data!

First steps to decarbonisation

-50 °C, with the bands remaining at 10 °C intervals (Figure 9). At this point, we start to see the flame envelope, along with all the flames in the downstream zone, and an underneath flame that we hadn’t been able to view previously.

We dropped the isotherms by a further -50 °C – so red is now 1120 to 1130 °C – and now we can see the temperatures in the superstructure (Figure 10). Another new flame has become visible on the lower right of the image.

With a further -50 °C drop, we start to see the thermal profile that may relate to the firing pattern (Figure 11). Importantly, we also obtain the first thermal data on the process billets, suggesting that the steel’s surface is hotter on the far side and cooler on the near side. This may be intentional or not if the breakdown roller was on that side.

Dropping yet another -50 °C (so -200 °C from where we started), we can confirm that the near side is cooler than the far side (Figure 12). This assures us that the temperature data is real, and not a result of any reflection.

Still analysing the first frame, we can use a palette that combines a colour image – in this case, the hot side with the flames – with a monochrome image of the steel (Figure 13). This allows us to differentiate between the metal stock and the furnace superstructure.

To look at the temperature of the steel itself, we created a 93 °C temperature band, which gives us 62 isotherms of 1.5 °C, allowing us to look at the billets (Figure 14). This also indicates that some of the upper burner blocks are cooler on the near side. This may be an impact of the angle of reflection, but it may also be worth checking the combustion air distribution – is there higher air flow on the burners on the near side?

Again, focusing on the steel, we created 25 °C isotherms, in the range of 950 to 1075 °C, and this shows a clear variance in the billet surface temperature – it is hotter on the far side and cooler on the near side (Figure 15).

All those analysis images have come from one frame of the thermal imaging camera – it records at 36 frames per

So, how do we apply this thermal data to decarbonisation? The first step is understanding where you are currently – how your furnace works, and how to optimise it.

An in-furnace thermal survey should be considered, as this will identify and fix holes, find overcooling points, and potentially save energy – and thus CO2.

There is also the potential to optimise the flames and thermal profile to suit the furnace through-put and improve yield, and also look to the variance to the budget.

You may also consider a permanent thermal imager installation, integrating temperature data into your Industry 4.0 control system.

It is also important to train, retrain, and retain furnace personnel – they will provide the help you need in the future.

Talk to your staff and retirees and find out what worked in the past, what didn’t – for example, fuel types – and why?

In the next five or six years, consider recruiting and developing process engineering personnel, validate existing CFD models to develop new furnaces for new fuels, improve yield and energy to reduce CO2, and develop the financial tools you will need.

In the longer term, when you truly understand what works, and the limits of your operation, you can consider alternative fuels and new furnace designs that will deliver the best results for a decarbonisation strategy. �

GHI SMART FURNACES is a familyowned company with more than 80 years of experience in customised complete solutions for melting, recycling and heat treatment of metals.

The GHI portfolio combines the design and manufacturing of industrial furnaces, the delivery of turnkey plants as well as SAT and Industry 4.0 consulting services. With our Industry 4.0 solution called Beyond Alea, we are digitising our customers‘ plants to improve, among others, purchase and operational processes as well as maintenance.

At GHI SMART FURNACES, we additionally focus on the application of new technologies and green energies in the production and recycling of metals - especially aluminium recycling - with the aim of reducing emissions and thus counteract climate change.

World leaders have become aware of the need to decarbonise our ecosystem and achieve zero emissions by 2050.

Carbon dioxide emission allowance prices have increased fivefold in some countries in recent years, and governments are increasing eco-taxes to push the deployment of clean technologies such as renewable energy and green hydrogen, while launching subsidy programs for R&D and investments in recycling facilities that bring additional benefits in terms of resource efficiency, energy consumption and carbon emissions. Figure 1.

With these investments and taxes, melting aluminium with hydrogen as a fuel could be cheaper than with natural gas in 5 years. Figure 2.

For all these reasons, we at GHI have been hard at work for some time to design The Aluminium Recycling Plant of the Future.

Our corporate strategy focuses on three

Emission-free plants

Using clean renewable energy that feeds an electrolyzer that produces Hydrogen and Oxygen. This electrolysis process is particularly suitable for recycling scrap in the Tilting Rotary Furnace as it uses both Hydrogen and Oxygen.

For post-consumer scrap recycling, Tilting Rotary Furnaces and Vortex Furnaces with Delacquering Systems will be fired with this low-carbon fuel.

Hydrogen will replace natural gas.

Holding and Alloying Furnaces use renewable electricity as a heating fuel. fundamental objectives that are crucial to our operations: � Digitalisation – with a team of 8 experts fully dedicated to Industry 4.0 we support our customers in optimizing their operational processes with the result of achieving relevant cost advantages. � Decarbonisation – a key element for our customers in the next few years.

Companies willing to work in markets such as automotive, will be required to reduce drastically their carbon footprint.

Our R&D efforts are focused in helping customers to achieve this. � Aluminium Recycling – as our main driving activity, in which we have become an international leader. Our goal is to help our customers in the transition from primary aluminium utilization to recycled material.

Reinventing aluminium recycling plants The Aluminium Recycling Plant of the Future must combine decarbonization goals with the principles of the circular economy, which we define as follows:

�

Zero-waste scenario

The plant recycles and treats all byproducts such as dross, salt slag cakes and generated fumes to create wastefree circular plants through sustainable aluminium alloy production methods.

We use a dross cooler that increases aluminium recovery from dross, reduces oxidation and emissions as well cooling space and time. Dross sorting facilitates the recycling of salts by specialised companies and the use of dross pieces to fill roads.

Total circularity is the clear path to the future, and we are already driving this change.

Figure 4.

�

Smart to be profitable

The Plant of the Future uses machine learning technologies to process Big Data and to propose “end-to-end” solutions with state-of- the-art equipment that improves cast house operations.

Another aspect we have identified is

Figure 2

14 Furnaces International December 2021

www.furnaces-international.com

Figure 3

that the largest equipment - we have a record of 65-ton tilting rotary furnace - provides a high economic return. The larger the furnaces, the more profitable they become.

The plant collects more than 10,000 data per second - Real time KPIs - which are stored and processed to simulate and predict performance with a digital twin.

This backflow of smart information enables our customers to optimise their plants.

The Beyond Alea platform, developed

by AMV and GHI, is the only one that integrates all plant processes with realtime monitoring. It allows us to simulate from the purchase of the most suitable scrap quality to the cost of each process to

achieve higher profitability of the plants.

It also allows us to carry out supplier evaluations and reduces non-productive time.

New Talents The new plant requires new hybrid job profiles that combine technical experts in metallurgy with skills in new technologies such as Big Data and machine learning.

Figure 5.

The road ahead Many of the aspects we have mentioned in this article are almost ready or close to be ready. Today, we can offer our customers smart equipment where flow optimisation and the electrification are

already a reality. Next year, we will be able to have autonomous equipment and a digital twin. We will need a few more years to develop Hydrogen technology, but today we are participating in several projects: Hydrogen burner technology; increasing the proportion of Hydrogen in the operation of a rotary tilting furnace and more. We think that in 2024 we will be able to offer a 100% tested Hydrogen equipment. At that time, the cost of melting with Hydrogen will be significantly reduced.

Join us on this journey to make this smart and clean future a reality. We think this is the moment to think about it and act. Because the future is now. �

Reducing emissions and increasing process using AI

Get to know how TERMICA Solutions is helping Arcelor Mittal Tubarao to reduce emissions and increase output using data science and machine learning as tools, but favouring business, people, and environment.

Tubarão plant is one of the units of ArcelorMittal in Brazil being an integrated steel mill that produces 7,5 MT/y of semi-finished steel (slabs and coils) and it was the first integrated steel mill worldwide to develop and file a CO2 Carbon Credit Program through the electricity generation using gases from its process.

Using its digital innovation program called iNO.VC, which includes Open Innovation, Arcelor called for solutions that could reduce the visible emissions of its chimneys. Therefore, the solution had the potential of reducing the social impact of the emissions on plant’s neighborhood.

TERMICA Solutions, an ind-tech that develops high-tech solutions, software, and hardware for industrial businesses, was selected to this challenge. By having a multidisciplinary, young, and agile team which includes electrical, automation, chemical, mechanical and software engineering as well as data science and artificial intelligence.

During the early stage of the development, the thermoelectrical process was chosen to receive the proof of concept due to its operation complexity as well as its environmental, social, and economic potential.

In this process, the boiler and its chimney are the main equipment. Four types of fuels are used in the boiler to generate steam having the products of combustion as by-product. This steam feeds turbines which generates electricity.

The plant has a Plant Information Management Systems (PIMS) installed and some variables were analysed by process specialists when emissions were reported. TERMICA has then concluded that data, the new oil, was available. But as well as the oil is refined to achieve a valuable resource, the data set should be.

The next step was a deep dive into the process. Even though TERMICA has several years of experience on the field, each process has its own features. Besides the technical matters, it was important to recognise that the process was running for decades by operators, and this knowledge should be captured. To do that, TERMICA has nominated a field engineer to be at the plant with three main goals: to understand the operation dynamics, the technical difficulties of the process and to ensure an excellent operator’s experience. Then the main variables that influence the process were determined based on literature and experience of the operators.

The historical data related to those variables was gathered. Once the dataset was huge, a computer-aided simplification based on relevancy was used. In this step, 196 variables were reduced to 36. Then a digital model of the physical process was created using neural network, which is an Artificial Intelligence tool. This model was then connected to the live data stream of the process, which enabled the prediction.

Therefore, variables can be changed in the digital model predicting the output that can be analysed if it’s the expected one before happening in the real world.

In other words, a live simulation gives an instant feedback of possible process changes, and several scenarios can be tested before changing it in the real world.

The last step was the optimisation, which means that given an expected output the

16 Furnaces International December 2021

www.furnaces-international.com

Future of Furnaces

g output in a continuous thermal model will test infinite scenarios and tell which inputs are required to achieve that goal.

The optimisation model now has three drives which can be selected by the operator: 1) increase the energy output regardless of the other variables; 2) Reduce the emissions 3) Increase the efficiency to achieve the best results energy and environmental wise.

Operators now have a tool to better

decide the maneuver according to the process drive at that specific moment resulting in: � Lower social impacts of the plant due to lower emissions � More revenue due to higher electricity generation � Less stress to the operators � Higher impact once this solution is easy scaled up to other cogenerations � Capturing hidden gains of other processes using the same strategy as well as the lesson learnt On top of that, we can conclude that a) Data science and

artificial intelligence can be applied to many different thermal processes to achieve outputs never imagined b) Enhancing operators is wiser than replacing them c) Regardless of the technology used, it is mandatory to involve the human being as the center of the solution from day one d) To achieve better and faster results, consider using human intelligence before applying artificial intelligence e) if a robust dataset is not available, IIoT is a good tool to gather it. �

Future of Furnaces

What if a furnace was intelligent enou When Mechatherm International Limited was asked about the future of aluminium furnaces, there were many potential candidates that could have been chosen, such is the growth and innovation within the Aluminium industry at present. After much internal discussion, it was decided sharing the results of an internal project that looked at the application of Artificial Intelligence to the problem of reducing energy usage, was the best move.

This project was born out of Mechatherm’s Service Division.

Following many successful visits to existing clients to enhance the performance of equipment that had been installed, they believed that more clients should be able to take advantage of the service being provided. Having previously demonstrated this tuning process could improve a furnaces performance by as much as 10% but with good engineers being a limited commodity, this service was difficult to scale.

What if the process our engineers were performing could be automated?

Research began into methods that would achieve the goal of automating the service provided as Mechatherm attended the Future Aluminium Forums in both Milan and Warsaw. Delegates discussed large-scale data processing using Artificial Intelligence and Big Data to solve real-world problems. The concept was becoming a reality, with key players in the field of Industry 4.0 coming together to share ideas.

Mechatherm have installed more than 300 furnaces in 30 countries globally, but to begin developing their idea they would need just one client willing to commit to trial, up until this point, unproven technology. A UK based client offered a live production machine, agreed to allow access, and give Mechatherm a chance to test their theory.

With an idea and a location, it was time to begin building a team. Firstly, a specialist software engineer experienced in managing large databases, A.I and Big Data was appointed to further develop the idea, utilising cloud technology

to effectively negotiate millions of furnace records. To support the internal development of the project several consultants were recruited to provide expert knowledge in areas that an experienced hand was needed.

Given time, Commissioning Engineers learn the intricate performance peculiarities and can best advise operators how to maximise a machine’s efficiency.

Combining several observations, operators can be made more aware of how to get the best from a piece equipment, specifically when a furnace is ready to receive or transfer material, effectively reducing the delays associated with normal operation. In technology terms this would equate to using an offline brain watching and learning how the furnace operates, gauging energy use per cycle and suggesting when the optimum parameters have been met.

A trial system was built and long before it could be implemented on a working furnace it was presented to their partner for approval, it was at this point the first obstacle was encountered. It was around this time that some high-profile industrial IT sabotage cases were in the news, and as the furnace was to be connected directly to the internet using cloud servers, subsequently support was withdrawn.

The project had to be taken back to the drawing board and an alternative solution built, if an online cloud system could not be used then an offline server would be the only option. Mechatherm began work on their own A.I engine server at a local level and found that the speed of feedback from querying millions of records to be on par with the cloud services. The project was back on track and with support reinstated an implementation date was set.

Installed, the system required a few

ugh to improve its own performance?

minor adjustments to the furnace control software adding the ‘Big Brother’ concept of the server and advising what action should be taken. A simple traffic light system was shown on a new screen giving operators an easy visual to make the choice to attend the load.

With the server stored in an airconditioned room away from the furnace, a monitoring station was set up allowing the Mechatherm team to observe the performance with no interruption to the furnace’s operation – all that was needed now was to press go!

Initial signs from the first couple of weeks indicated the system had a long way to go before it could reliably advise operators when action should be taken, this was the second major setback. With constant feedback from Mechatherm’s global team of consultants it steadily became clear that with any new system

like this, it needed to learn, it needed data, as it simply didn’t know enough to perform the role it was given. A KPI system was created to measure accuracy and record how intuitive the predictions of an early finish of a charge were based on time as a percentage. This began at around 50% accuracy. The team was confident that with time this would improve.

Steadily, over many weeks, the system data grew to tens of millions of records and with the increased volume, predictions held more certainty. The accuracy edged towards 60% and continued to improve as more and more of the decisions showed a true representation of the furnaces state. This system was based purely on recorded data, devoid of any need to share details about what had been loaded into the furnace, ruling out any operator inaccuracies and exclusively responding to changes in temperature and output of

the combustion system.

It was agreed with Mechatherm’s partner that at 85% accuracy the system recommendations would be followed for the charge and transfer requests, this would allow the calculation of fuel savings compared to standard operator usage.

Finally at 88% the system took over and the last recorded fuel savings were at 7%.

The system was working.

Just as the project was beginning to gain momentum and show positive results the final obstacle was encountered. The Global pandemic hit and investment and support for industry 4.0 was understandably withdrawn. The project was temporarily shelved. As the world begins to re-emerge and fuel savings of 7% on initial trials already proven, Mechatherm continue to develop this technology with the aim to standardise this technology for all of their M and X-Series furnaces from 2023. �

NEWS: GLOBAL FURNACES

SECO/WARWICK MANUFACTURER ADDS FOURTH TEMPERING FURNACE An international manufacturer of cutting tools has ordered another vacuum tempering furnace from SECO/VACUUM. Maciej Korecki, Vice-President, Vacuum Furnace Segment, SECO/WARWICK Group says: “This customer demands – and has come to expect from us – a complete range of benefits, including precision heat treat uniformity, consistency from one workload to the next, and fast processing speeds along with low energy consumption. This often contrasts with requests from our other clients who are looking for a single feature, for instance, high uniformity in heat treated parts to predict and prevent distortion. All the other features with Vector come as added value.”

Vector®, SECO/WARWICK’s single chamber horizontal vacuum furnace, is loaded with capabilities. With hundreds of systems installed worldwide, SECO/ WARWICK’s vacuum furnaces have a proven record of meeting and exceeding performance expectations.

The horizontal, front-loading furnace has been purpose-built to accommodate the customer’s needs with an all-metal hot zone for clean vacuum processing. As with the earlier furnaces, one of which was installed at a different facility, the new furnace includes a convection fan and a pressurized gas quench for quick cooling.

According to Piotr Zawistowski, President, SECO/VACUUM, “There is no stronger statement validating SECO/VACUUM’s predictable and excellent product performance than the customer who continues to order more of the same technology from us year after year as they expand. We are privileged to be a part of their growth.”

Vector single-chamber vacuum heat treating furnaces are the ideal solution for machine tool manufacturers. It is available with curved graphite elements or an all-metal hot zone and can be used for most standard hardening, tempering, annealing, solution heat-treating, brazing and sintering applications.

HYDRO SUNNDAL INVESTS IN CAPACITY EXPANSION Hydro expansion Hydro has announced its intentions to invest NOK 60 million in a new furnace for the production of foundry alloys at Hydro Sunndal.

Hydro claims that the investment in Sunndal increase the capacity for production of special alloys to, among others, the building, construction and automotive industries by 35,000 tonnes per year. This investment will also increase the flexibility to switch between products and thus make the plant more robust in a cyclical marked.

The project will start immediately and is expected to be completed in the first quarter of 2023.

Plant Manager at Sunndal Roar Ørsund commented on the announcement, “We are pleased with this decision, which strengthens Hydro Sunndal’s flexibility in the market and promotes greater consumption of low-carbon aluminium. A customer example we are pleased with is that aluminium from Sunndal will be used in Google’s new office building in New York.”

Ola Sæter, Head of Primary Production in Hydro added, “The demand for metals and materials produced with renewable energy is increasing and this offers great opportunities for Norwegian industry. Hydro has high ambitions for growth in Norway and investments in Sunndal are an important step in implementing our strategy that will strengthen our market position in premium low-carbon aluminum,”

CLEVELAND-CLIFFS ENTERS THE SCRAP BUSINESS AND ANNOUNCES ACQUISITION Cleveland-Cliffs Inc. has announced that it has entered into a definitive agreement to acquire Ferrous Processing and Trading Company (FPT) to optimise the productivity of its existing Electric Arc Furnace (EAF) and Basic Oxygen Furnace (BOF).

Based in Detroit, FPT is processes and distributes prime ferrous scrap in the United States, representing approximately 15% of the domestic merchant prime scrap market. FPT currently processes approximately three million tons of scrap per year, approximately half of which is prime grade.

Lourenco Goncalves, Cleve-

land-Cliffs’ Chairman, President and CEO said, “Cleveland-Cliffs is entering the scrap business as a major player through the acquisition of a large scrap company.

Even more importantly, FPT has a very meaningful presence in prime scrap.

With all the new flat-rolled EAF capacity coming online in our market over the next four years, prime scrap will only become more and more scarce. “ He continued, “As the largest supplier of flat rolled steel in North America, Cleveland-Cliffs is the main source of the steel that generates prime scrap in manufacturing facilities. Further-

more, throughout our entire footprint, Cleveland-Cliffs also consumes a very significant amount of scrap in our EAFs and BOFs. The acquisition of FPT will enhance our ability to buy back prime scrap directly from our clients, cutting the middlemen and improving the margin contribution from scrap for both Cleveland-Cliffs and for the manufacturing and service center clients that will be able to sell scrap directly back to us.”

The acquisition has been approved by the board of directors of Cleveland-Cliffs and is expected to close in the fourth quarter of 2021.

Reducing CO2 emissions in the BF/ This article will examine how far BF/BOF steel plants can progress towards carbon neutrality and will then look at different ironmaking strategies in the main steelmaking countries/regions.

Burden preparation Sintering process � replacing carbon (coke breeze, anthracite) with biomass (such as charcoal) fuel sources, � utilize ‘green’ H2 as ignition furnace fuel, when ‘green’ H2 becomes available, � switch to electricity generated from renewable sources (so-called ‘green electricity’) for fans, drives, etc.

Pelletizing process � replacing carbon additions (coke breeze, anthracite, etc) with biomass (such as charcoal) fuel sources for hematite ore pelletizing; � due to the exothermic oxidation of magnetite to hematite, use of magnetite ores in pelletizing does not require carbon so, for example, by pelletizing magnetite ore LKAB in Sweden is already producing ‘greener’ pellets; � plasma torch-based induration using ‘green’ electricity: a supplier of plasma torches (PyroGenesis) is piloting this with a major pellet producer; � switch to green electricity for fans, drives, etc.

Coke ovens � Real ‘green’ opportunities are limited to green electricity for motors, fans, etc. CDQ (coke dry quenching) provides some BF coke rate reduction. � Non-recovery coke ovens technology reduces emissions, � Biomass addition to coking coal.

Also the CO2 emissions of the met coal feed should be taken into account.

By contrast, iron ore mines exhibit much lower CO2 emissions (kg/ton), associated with electrical power and fuel use in mobile equipment and processing facilities. Some examples are shown below, from Teck (coal) and Rio Tinto (iron ore). Figures 1 and 2.

/BOF A great deal of what has been written about the roadmap to carbon-neutral steelmaking revolves around the shift from integrated steelmaking via the blast furnace/basic oxygen furnace (BF/ BOF) route to the direct reduction/scrap/ electric arc furnace (DRI/scrap/EAF) route that is expected to take place over the coming decades. However, there are at least two reasons for exploring what can be done with the existing BF/BOF steel production route:

� In the interim, before process conversions take place, it is still desirable to reduce CO2 emissions in BF/BOF production.

For some regions of the world, especially where the majority of global steel production occurs, the ultimate conversion to DRI/scrap/EAF steel production might not be feasible, so it is essential to examine what can be done with the BF/BOF route.

Injection of hydrogen, natural gas, biomass/bioenergy, plastics Globally, nearly all blast furnaces, outside of North America and the CIS, inject pulverised coal (PCI) at rates of 150-200 kg/ton hot metal; this could eventually be replaced by ‘green’ H2 injection; as an intermediate step, injection of natural gas or ‘blue’ H2 also reduces CO2 emissions.

Steelmakers such as TKS are conducting trials with H2 injection. Natural gas

27 www.furnaces-international.com

Furnaces International December 2021

Global Furnaces

Figure 1. CO2 from coal production (Teck)

injection is prominent in the CIS and NAFTA regions; in NAFTA many also coinject coal and gas.

However, until H2 is available as an injectant in sufficient quantity and at economic cost, some PCI, along with natural gas injection, will still be desirable from the perspective of overall CO2 reduction as coke rates can be minimized with such ‘co-injection’ of natural gas and coal. Injection of H2 may be maximized with equipment modifications to recycle and reinject a portion of the top gas. Satisfactory BF operation has been maintained with coke rates as low as 250 kg/tHM, suggesting that co-injection (coal, natural gas) rates of 250 kg/tHM or H2 rates of 40 kg/tHM are feasible.

Injection of biomass and plastics: Whereas biomass (such as charcoal) can be claimed to fit into a circular economy, plastic injection merely displaces primary carbon usage, similarly to CO2 use for chemical upgrading. Not all plastics are suitable for injection, such as high chlorides in PVC that are detrimental for the BF process.

Co-injection of multiple injectants: co-injection of coal, gas, biomass, plastics and so forth, can maximize coke replacement and yield net reduction in CO2 emissions. All injectants, other than H2, convert to CO in the raceway. Though carbon exhibits the highest caloric value, gases with hydrogen promote direct reduction and might provide good replacement ratios.

Table 2. Concentrates and pellet feed grades %

(sinter, pellets) with higher Fe content, thus reducing required rates of sinter and/or pellet consumption with attendant reduction of CO2 from these agglomeration processes. Agglomerates with higher Fe content also reduce blast

furnace fluxing requirements (limestone/ dolomite) and hence slag rates with attendant reduction in coke rate and CO2 emissions. Furthermore, higher proportions of agglomerates (i.e. less lump ore) in the BF burden reduce coke rates and, therefore, CO2 emissions.

However, working against this is the long term decline in Direct Shipping Ore (DSO) grades, summarized as the averages for nine of the principal sources of sinter feed fines in the table below (from Australia, Brazil, South Africa and Mauritania). Sinter feed is the largest component of global iron ore seaborne trade, comprising perhaps >80%. Over a 20-year period there has been a clear decline in the Fe content and an increase in acidic gangue and P levels that has several implications: increased BF slag volumes, coke rates and increased BOF flux consumption. Table 1 and 2.

However, for iron ore concentrates and pellet feed, the history is somewhat different, due principally to the ability to maintain or improve grade through the use of beneficiation technology. The table above shows the same comparisons for 1998, 2010 and 2019 for Fe, SiO2, Al2O3 and P for five of the leading pellet feed and concentrate producers (from Brazil, Canada, Sweden and Mauritania) and indicates little substantive change in overall quality.

Charging metallic Charging of metallics offers significant benefits in coke rate reduction (0.3kg coke rate/1.0kg metallic Fe) and thus reduction in CO2 emissions; metallics can replace 25% to 40 % of charged Fe units, but some CO2 credit is needed to overcome

the higher initial cost of metallics. The practical limit of HBI use in BFs is about 25% to 40 % of the iron bearing charge as a certain minimum level of coke is necessary to support the descending BF burden and maintain its permeability

and to provide the gas volume necessary to preheat incoming raw materials.

Higher blast temperatures Higher blast temperatures achieved by plasma superheating of the hot blast

can provide a direct benefit through reduction in the coke rate and thus in CO2 emissions (only if based on ‘green’ electricity) as every 100°C increase in hot blast temperature can save about 9 kg/T coke.

Utilization of CO2 scrubbed from top gas can be considered for other applications, such as chemicals. The ULCOS top gas recycle BF concepts (see below) have been well demonstrated at the LKAB experimental blast furnace. Figure 3.

Best practice technologies Waste heat recovery: sinter plant waste heat recovery is incorporated into a number of the technologies aimed at sinter plant pollution control.

Blast furnace top gas pressure recovery turbines (TRT): such turbines are incorporated into all of the newer, larger blast furnaces operating at high top pressure.

Coke dry quenching: coke dry quenching (CDQ) is extensively used in countries with high energy costs and also has a small coke rate benefit and so could be helpful in reducing CO2 emissions.

Figure 4.

Other BF energy efficiency measures include: � burden and gas distribution control to improve gas utilization: conversion of any remaining two bell top furnaces to bell-less tops can increase gas utilization and reduce coke rates; � digital process control to optimize hot metal: digitization of the BF process can also lead to reduced coke

rates and CO2 emissions through more precise adjustment of blast conditions and burdening.

Top gas recycling This includes injection of reducing gases in a second bustle pipe above the cohesive zone along with possible injection of additional reducing gases such as CO, CH4 and H2 through the tuyeres.

BOF off gas energy recovery: this is another technology that has required high energy costs to justify the investment involved, but otherwise has no other potential for process improvement.

Heat recovery from slags: dry granulation of slags is yet another technique that offers no additional process benefit, so project investment return depends upon energy pricing.

Figure 5.

31 www.furnaces-international.com

Furnaces International December 2021

Global Furnaces

Utilization of slags: many BFs direct their slag to slag granulation facilities, usually joint ventures with cement producers to provide feed material for cement production. This does provide a CO2 reduction benefit for the cement producer as it offsets the production of clinker, normally produced in coal-based, environmentally unfriendly rotary kiln operations.

Power generation from any excess plant gas sources: many steel plants globally direct excess plant gas into co-generation plants that can generate electricity for plant or external use. However, the priority applications for plant gases are within the same or related processes such coke oven under firing, BF stoves, sinter plant burners or rolling mill reheat furnaces.

Carbon Capture Utilization and Storage (CCUS). This topic will be covered in the upcoming IIMA White Paper

Differing regional approaches China, ASEAN Age of plant/equipment – The figure below (source: BHP) illustrates the median age of ironmaking/steelmaking facilities in all regions of the world. The facility ages in years in China (12), India (18) and other APAC (6) (Asia Pacific: Vietnam, Indonesia, Malaysia, etc) are in regions that account for over 75% of global steel production; thus the CAPEX barriers for major process equipment changes are formidable; the OPEX barriers (Australian iron ore less suitable for DRI) are already high. These barriers point in the direction of incremental CO2 reduction within the existing BF/BOF route as exemplified by the Japanese Course50 programme outlined below. Also with respect to the BOF, increasing scrap ratios in the BOF charge can be expected as China’s scrap reservoir grows. Essentially, the same level of steel production, but with lower hot metal ratio in BOF decreases specific CO2 emissions per ton of steel. Figure 4.

Japan: Course50 Programme The Japanese steel industry’s Course50 programme (CO2 Ultimate Reduction System for Cool Earth 50) consists of: � CO2 capture and storage from blast furnace gas: � direct CO2 capture (CO2 storage is not included in the project); � reduction of CO2 capture energy:

by using waste heat from steelworks, input of external energy is minimized. � Promotion of carbon-alternative reduction in the BF � utilization of H2 in coal as a BF reductant (conventionally used for power generation and heating); � development of a future H2 reduction technology.

South Korea Posco’s earlier phases focus on energy efficiency, reduction of coal usage, COG or LNG as reducing agents and increased scrap use; the long range plan emphasizes the HyREX (modified FINEX process), as shown below. Figure 5.

Europe Europe is still heavily dependent upon the BF/BOF route. Current EU plans strongly emphasize a transition to the DRI/EAF route, as will be outlined in the upcoming IIMA White Paper.

NAFTA The DRI/scrap/EAF route is well established here. About 12Mt EAF capacity has been recently commissioned or is under construction in the USA, which will significantly increase the EAF share of steel production beyond the 69.7% of 2019 (see below) and thus demand for scrap and ore-based metallics. Figure 6.

Brazil Brazil already has a well-established charcoal-based, lump ore-fed mini-BF sector that is primarily a producer of merchant pig iron for local and export

markets for EAF and foundry applications.

Brazil also has a large coke-based BF/ BOF steel production sector where CO2 reduction efforts are focused on charcoal-based PCI along with natural gas injection. The large iron ore pelletizing sector, led by VALE, is exploring CO2 reduction via biomass replacement of anthracite, plasma indurating burners and other initiatives.

Another development is Vale’s plans to commercialize the Tecnored smelting reduction process using briquettes of iron ore fines, waste oxides and/or biomass materials.

How far can they go?

The question of how far can integrated mills go can be answered as follows: the Course50 programme in Japan is based on maintaining the BF/BOF route, but aiming at 50% reduction in CO2 emissions. A study by SMS Paul Wurth indicates potential of up to 4476% reduction in CO2. The pathways to carbon-neutral steelmaking will be evolutionary rather than revolutionary.

There is considerable scope for reduction in CO2 emissions from the integrated steelmaking route, although not to the extent possible for the H2-based DRI/EAF route.

Economics: CAPEX and the reliance on expensive DR grade pellets versus lower cost sinter feed ores and waste oxides will play a role in steel company decisionmaking, as will the attitudes and policies of governments and regulators. Also, additional processes will be needed to utilize waste oxides. �

CoJet burners firing uniformly around the furnace

25 years of CoJet technology for the EAF

34 Furnaces International December 2021

Global Furnaces

The introduction of Linde’s CoJet coherent injection technology 25 years ago is now adopted by over 170 EAF operators resulting in greater efficiency of operations and thereby a reduction in CO2 emissions, a factor further enhanced by the system being ‘H2 ready.’

In September 1996. Gerdau MacSteel at Fort Smith, Arkansas, was the first steelmaker to install a CoJetTM Gas Injection system in its 60-ton electric arc furnace (EAF), replacing conventional manual lancing with the new concept of a wall mounted multi-functional fixed burner/lance system. Twenty five years later, in January 2021, fellow group steelmaker, Gerdau Steel in Midlothian, Texas, installed three CoJet systems in its 150-ton EAF. In this 25-year period, 172 furnaces have installed CoJet technology across the continents of the world, in North and South America, in Europe and Asia.

Coherent jet injection technology was conceived in the USA by Praxair. Praxair merged with Linde of Germany in 2019 to form Linde plc. This new breakthrough technology, named CoJet, was a significant step in injecting chemical energy into an EAF in an efficient manner.

It was the first to introduce the concept of fixed wall mounted injectors, with each injector designed to perform multiple functions, incorporating an oxyfuel burner, oxygen lancing, post combustion, and carbon injection.

“That the CoJet programme has been a success, is clearly evident”, says Pravin Mathur of Linde, who pioneered the implementation of CoJet technology in electric arc furnaces. “The testimony to its wide acceptance in the EAF melting process can be summarised as follows”: � Over 170 furnaces authorised to operate this technology worldwide over the past 25 years, and perhaps twice as many additional furnaces using a similar concept; � A wide geographical distribution with customers in North and South America, Europe, and Asia; � Furnaces ranging in capacity from 30 to 400 metric tonnes tap weight; � The number of injectors installed per furnace ranging from one to five; � Various furnace types including AC, DC, Shaft, Consteel and Conarc; � Raw material input to the furnace with wide ranging variation – 100% scrap, 100% DRI, a mixture of scrap and DRI, various percentages of hot metal, continuous scrap feeding; � Furnaces operating under constant flat bath conditions with continuously varying bath heights; � Inherent burner capacity of 3MW to 6MW per injector; � Designed oxygen lancing from 600Nm3/h to 4750Nm3/h;

� A wide spectrum of oxygen practice from 12Nm3/ton to 55Nm3/ton.

The technology Exploratory research on supersonic gas jet behaviour by Linde’s corporate fellow, Dr John Anderson, first led to the concept of flame-shrouded jets. These become coherent and maintain their exit velocities and momentum over long distances. For example, an optimum flame shroud extends the length of a Mach 2.0 supersonic oxygen jet in ambient air from around 15 times the nozzle diameter to about 70 times the nozzle diameter (Figure 1).

In an EAF, the laser-like oxygen jet from a coherent injector travels significantly farther than an oxygen jet from a conventional supersonic lance. Hence, coherent jet injectors can be positioned well above the bath in the sidewall of the furnace, and still carry out effective bath lancing. Also, when the coherent jet of oxygen produced by the nozzle impinges and penetrates through the slag and into the molten steel bath, the concentrated momentum of the oxygen jet dissipates in the steel as fine bubbles, providing deep penetration and effective slag-metal mixing. This results in high efficiency lancing and decarburisation.

The CoJet injector assembly, in addition to lancing, is also designed to provide multiple functions. Each injector also functions as a burner to melt scrap and to simultaneously inject supplementary oxygen at subsonic velocity for post combustion. The post combustion oxygen is introduced in a controlled fashion at a specific shallow angle and close to the main lance oxygen to achieve maximum benefits, not only during scrap melting, but also during flat bath periods. This results in a further reduction in electric power consumption, and an increase in furnace productivity.

The CoJet injector assembly (Figure 2) also incorporates a feature to introduce carbon. The carbon is injected in a fully automated mode through a port specifically located to allow for effective slag foaming and reduction. Under proper conditions, this injected carbon can also provide some recarburisation of the bath.

The benefits resulting from this efficient mode of carbon injection is the excellent slag foaming achieved, with a significant reduced quantity of injected carbon used.

Gas requirements CoJet technology is fuel flexible in that a

wide range of hydrocarbon fuels can be used for the burner and shrouding gas.

Natural gas, desulphurised coke-oven gas, LPG, kerosene, and fuel oil have all been commercially deployed.

Linde has also developed CoJet using hydrogen as the shrouding gas and burner fuel. “Hydrogen is in fact an ideal fuel to produce coherent jets,” said William Mahoney, who spearheaded the use of hydrogen, while leading the development of coherent jets in applications other than the EAF. “Not only does hydrogen produce the longest coherent jets for oxygen lancing (greater than 85 times the nozzle diameter), it also improves the heat transfer efficiency for scrap melting”. The existing CoJet burners can be easily used with hydrogen with minimal modification (Figure 3).

Given the high temperature atmosphere in an EAF, questions are periodically raised by customers about the need for a shrouding fuel to produce coherency. While hot ambient conditions do improve jet lengths of a conventional O2 jet, up to about 35 nozzle diameters, laboratory studies and field experience has shown that they do not produce jet lengths comparable to a perfect coherent jet (>70 nozzle diameters). In addition, the jet length is not consistent throughout the heat, and leads to negative impacts on furnace operation especially when the bath height changes through the heat based on type of operating practice and general refractory wear (Figure 4).

The purity of oxygen required is less stringent than for a BOF and can be

produced by Vacuum Pressure Swing Adsorption (VPSA) in which most of the nitrogen is ‘filtered’ out of the air by molecular ‘sieves’ resulting in a gas containing 90-92% oxygen and 4% argon. This is a lower cost method than cryogenic liquification of air.

Operational features and benefits A typical CoJet system includes multiple injectors with associated assemblies for mounting on the sidewall of the furnace, a valve skid to independently meter and control the oxygen and fuel, a programmable logic controller, and an

operator station usually located in the furnace pulpit.

Historically, conventional EAF operation had been carried out by manual lancing and carbon injection, usually through an open slag door. By using coherent jet technology, the furnace is converted from a manual operation to a fully automated sequenced operation with the slag door closed. In addition, the oxygen and carbon are now uniformly introduced through multiple injectors around the furnace in a homogeneous manner as shown in Figure 5. This allows for the use of higher overall chemical energy and improved safety for the operators.

CoJet coherent jet technology provides a fully automated sequenced operation.

Once a bucket charge is added and the roof closed, the injectors automatically begin to operate in their pre-programmed sequence. With staged firing profiles, the injectors operate to provide different flame shapes. Initially, the injectors function in a low burner mode to melt the scrap. At this stage, a wide flame is used to heat a large area of scrap. Subsequently, a high burner mode is used with a more cutting or penetrating flame, followed by a low lance cutting mode that is deployed to rapidly cut through the heated scrap and facilitate rapid melting. After the scrap is melted with this sequenced burner/low lance cutting operation, the injectors automatically switch to high lancing and decarburisation.

Concurrently, carbon injection is automatically initiated to inject carbon

at set flow rates. Throughout this run, the post combustion oxygen is continuously added, the flow rate modified for each mode of operation of the injectors; ie low burner/high burner/low lance/high lance-refine. This allows for a high rate of utilisation of the CO evolved during the heat, and its combustion to transfer energy to the bath.

A furnace operated with CoJet can immediately reap benefits. Typical cost savings derived are from a combination of the following parameters: � Reduced power consumption � Increased productivity � Elimination of supersonic lances and manipulators � Significantly reduced maintenance � Improved yield � Reduced refractory wear at banks � Reduced gunning

� Reduced injected carbon � Improved delta life

Some of the other factors that lend added value to using a coherent jet technology are: � Automation – less operator dependent � Consistency – from heat to heat � Improved slag foaming – higher rate of power input � Non-water-cooled injectors – easy

to check � Total flexibility – option to selectively lance with any injector(s) � Improved safety.

Table 1 illustrates average actual savings in a 125 short ton AC furnace with three CoJet injectors.

“With over 170 furnaces around the world authorized to use CoJet technology, considerable knowledge has been garnered at Linde from their experiences with a wide range of furnace types and operating practices,” said Sumant Warty, who leads the worldwide commercialization of CoJet technology at Linde.

Jet characteristics Coherent jets can be designed for remote location on the sidewall even as high as 1.85m above the bath. CoJet offers coherency of the jet, at supersonic speeds, up to 2.5m in length from the nozzle face.

This factor becomes even more critical when furnaces are operated with hot metal, 100% DRI feed or continuous feeding of scrap. Under these conditions, the furnaces are in a flat bath condition all the time and the bath height changes significantly over the extent of the heat.

Under such conditions, it becomes critical to have accurate quantitative data on jet length. This helps ensure that a truly coherent jet is designed with the appropriate requirements, and with its characteristics maintained over the requisite distances. Well-designed coherent jets can function effectively in such furnaces with continuous feeding, or even in furnaces where there are bath height changes due to bottom wear.

It is critical to have quantitative data on coherent jet length and ‘perfect’ coherent

jets to handle variations in bath height without splashing or creating negative effects on the furnace. Imperfect coherent jets, when installed in such furnaces, can render considerable damage to the furnace and negatively impact the operation. Typical problems that can be encountered with poorly designed coherent jets are: � Excessive splashing � Excessive overheating of panels � High delta wear � High refractory wear � High levels of FeO � Poor yield Another key aspect of coherent jets

is the shroud ports, which are integral to the injector design. Maintaining the appropriate gas flows through the flame shroud (fuel gas and shroud oxygen) is critical for proper operation in each of the modes. If the flows to the shroud ports are not independently controlled, the integrity of the coherent jet can be compromised during a campaign. Such occurrences lead to negative effects on the furnace, some of which are listed above.

Sometimes customers in countries with high fuel prices request that the coherent jet offer be made without using a shrouding fuel. As indicated in Figure 4, this is not advisable, and it results in excessive splashing, loss in yield, longer heat times, increase in O2 consumption due to lower injection efficiency, and significantly higher carbon injection consumption to combat raised FeO levels.

The effects of flame shrouding on the penetration length of a supersonic oxygen jet are huge. While, relative to ambient air, the hot furnace gases increase the natural jet penetration length, the application of a flame shroud maximises the coherent jet length to more than double the length inside the hot furnace.

Lancing efficiency and carbon When lancing with coherent jets, the decarburisation efficiency improves considerably. This becomes a useful tool to reduce refining times, improve productivity, and make gains in power savings. Generally, carbon injection with the CoJet system has demonstrated that best results are achieved with additions of less than 5-8 kg/ton. With the slag

door closed, the foamy slag generated can be retained and carbon injection proportionally reduced or stopped.

Reduced injected carbon of up to 60% achieved in some cases. In addition, since the ingress of air is curtailed when the slag door is closed, NOx emissions that form in the vicinity of the arc are reduced.

The improvements in jet penetration, uniformity of lancing around the furnace and better slag foaming also result in lower nitrogen levels in the steel. Reductions up to 10 ppm have been achieved, both in scrap and DRI charged furnaces.

Maintenance A frequent concern of any melt shop is the kind of attention and the level of maintenance necessary for any new system and hardware installed. This aspect is crucial since any down time needed to carry out maintenance, comes at a price.

The injector itself requires no cooling water and weighs barely 13kg. A quick inspection of an injector takes about 10 minutes. Generally, such an inspection is advised at least once a week on a down day to ensure the integrity of the nozzle face. A notification in the operator station is available to alert the operator, in case any specific changes occur.

Another key benefit from a maintenance perspective is the life of the coherent jet injector. Experience shows, provided adequate cooling water is maintained, basic flows and pressures of oxygen and fuel are held and sustained in the various modes – especially during charging, the injector life is significant.

Customers have been using CoJet injectors and panels for more than a year, and in some cases, over 18 months.

Sustainability In recent years the EAF’s lower carbon footprint has grown increasingly important compared with the integrated blast furnace – basic oxygen furnace (BFBOF) route. For an EAF charging 100% scrap, a reduction in energy requirements as high as 75% can be achieved, and scrap is defined as carrying zero CO2. CO2 emissions from an EAF charging 100% scrap are in the order of 0.33tCO2/tonne of steel produced.

Over the past 25 years, global EAF output has doubled from 246Mt to 494Mt. However, the share of EAF global steel production has fallen from 33% to 26% over this period, reflecting the vast expansion of steel output from

China using the BF-BOF route, with EAF production here accounting for only 9% of output in 2020. The ratio of EAF to BF-BOF production is generally much higher elsewhere; 42% in Europe and Asia (excluding China), and 70% in NAFTA countries, in 2020.

Total CO2 emissions are dependent on the carbon emissions relating to electricity generation, the fuel gases used in burners, electrode consumption, carbon injection, and so on.

If quality requirements demand part charging of primary iron such as DRI, pig iron or hot metal, the CO2 emissions increase. Indeed, it is impossible to reach zero emissions in any steelmaking process since the steel itself requires carbon as an alloying element. Even DRI produced with 100% hydrogen requires carbon to passivate it to avoid spontaneous combustion on exposure to moisture, unless directly linked via an inert conveyor to the EAF. The ability of CoJet technology to use hydrogen as the fuel for shrouding and for burner flame without major conversion of the hardware readily lends itself as a ‘H2 Ready’ application for the steelmaking process and one that will further lower the CO2 footprint of the EAF once ‘green’ hydrogen can be supplied at a commercial price.

Other applications of CoJet CoJet technology has been demonstrated in the basic oxygen furnace (BOF) replacing the top lance with a CoJet system. The greater penetration and smaller area of impact of the CoJet coherent flow of oxygen resulted in less splashing, improved mixing of metal and slag, shorter blowing times, reduced slopping and improved efficiency of oxygen use. In trials, the degree of stirring was similar to that achieved using bottom stirring through porous plugs. The amount of slopping fell from 50% when using a conventional lance, to 20% with CoJet. In addition, heavier scrap can be included in the charge, FeO is lower, resulting in improved yield, and refractory wear is less. From a quality point of view, there is reduced nitrogen in the steel. The CoJet top lance can potentially be used in burner mode for scrap preheating to help increase scrap charged to the BOF.

Non-ferrous applications

smelter using Inco’s MK ‘top blowing, nitrogen bottom-stirring converter’. A marked improvement in the efficiency of oxygen utilisation was achieved through a reduction in ‘horn’ formation at the lance tip, which has stopped the need for mid-charge lance tip cleaning thereby increasing productivity. Cleaning is still required at the end of each charge, but the task is now much easier and quicker.

At Rio Tinto Kennecott in the USA, CoJet technology has been installed to speed up melting of scrap copper in the anode-refining furnace, and also achieve rapid sulphur removal by oxidation. The lancing capability of the process further helps to remove hearth accretions.

The increased scrap melting capacity in the anode furnace is growing in importance worldwide in support of minimising CO2 efforts.

Conclusions and outlook The past 25 years have seen a dramatic increase in the production of steel in the electric arc furnace with a growth in furnace heat size coming close to that of many BOF converters (Figure 6).

To alleviate longer tap-to-tap times for refining resulting from the shallower hearth of the EAF compared with the BOF, steelmakers are searching for means of speeding up reaction rates in the EAF. CoJet technology has proved to be an excellent way of achieving this goal.

As the proportion of EAF steelmaking increases with the move to decarbonise steel production, CoJet technology becomes of even greater significance in the drive to support this decarbonisation roadmap.

“The introduction of CoJet 25 years ago changed the industry standard completely, created many learnings that yielded further operational improvements, and formed a platform for the future. CoJet is ‘H2 ready’, but there are also a number of other interesting developments with ‘fluidic burner’ and multi-injection, which will make a great technology even greater going forward”, said Joachim von Scheele, who carries the overall responsibility for commercialisation of Linde’s technologies to the steel industry.

“CoJet is an excellent example of how Linde has been making the world more productive, but it is also providing a tool for decarbonisation available today and ready for the future,” Scheele concluded. �

Gentlemen, thank you for joining us.

Let’s just jump right in. Brian, since I picked on you last, let’s go to you first on the questions.

IS HYDROGEN COMBUSTION THE FUTURE? DG: Is this Hydrogen combustion thing coming? And, if so, how soon and what’s driving it?

Brian Kelly (BK): It is coming and there is going to be a lot of back and forth in that it doesn’t make sense and all that.

It is here. We’re seeing inquiries from customers that ask, “Hey, do we have burners that do this, control systems and stuff that do that?” The news that I get emails on, for example, is that with one of the steel companies in Europe, they already said their plan is going to be entirely Hydrogen. We’re delivering billets right now of Hydrogen.

So, yes, it’s coming. Is it coming soon?

It’s here today. Widespread? That’s going to be a longer road. I think you’re going to hear from people that know more about it than I do, but, certainly from industry buzz, we’re testing burners, we’re making sure our burners run on partial Hydrogen, full Hydrogen, safety valves, control valves, and all that is definitely within a lot of the testing that we’re doing right now beyond the usual R&D on lower emissions burners and things of that nature.

JEFF RAFTER is vice president of sales and marketing for Selas Technologies out of Streetsboro, Ohio and has a rich history in the combustion industry as well, including many years with Maxon Corporation. He’s got 28 years of industrial experience in sales, Research & Development, and marketing. He’s a combustion applications expert in process heating, metals refining, and power generation and has also served 10 years on the NFPA 86 committee and holds a patent for ultra-low NOx burner designs. He is also an IHEA member.

Finally, we have BRIAN KELLY with an equally rich history in combustion, spending most of his years at Hauck Manufacturing in Lebanon, PA, where he did a lot in sales and engineering before they were purchased by Honeywell. Brian currently works for Honeywell and is also an IHEA member.

Jeff Rafter (JR): I have a slightly different answer, but I agree with Brian. I think Hydrogen combustion has been here for over a century. The difference has been, it’s been largely restrained to a few industries that have a regular Hydrogen supply. A great example would be refining and petrochemical industries.

We have had, for literally decades, burners designed to burn pure Hydrogen, for example, in applications like ethylene crackers.

The fundamentals of Hydrogen combustion are very well known. The next evolution that we’re currently in the process of seeing is taking more industries into an availability of Hydrogen as a fuel and modifying designs and process heating equipment to accept it. There are fundamentally a lot of changes that occur when you switch the fuel, and we can get into more of those later with more

relevant questions, but it doesn’t come without challenges. There is quite a bit to be done, but I think the fundamental science is already well-known. There is a lot of design work to be done and there is a lot of economic and supply development still yet to be had.

John Clarke (JC): Yes, I certainly think it is coming, but the timing is uncertain.

And, when I say “coming,” I mean deployed in a certain or large volume.

When we simply talk about Hydrogen, I do think the order of deployment is somewhat predictable and when it comes to pure Hydrogen, I think it will likely be deployed first for transportation, and only after that need is met, as a process heating fuel, widely.

Now, if there is a breakthrough in battery technology, this order of deployment may change. But, right now, it looks like Hydrogen represents an opportunity for higher energy density for long haul transportation. And, if we’re pushing hard to reduce CO2 or carbon emitted, I think policy will be implemented in a means to

maximize a reduction of carbon. That’s where I think they’ll be pushing harder.

Now, that said, partial Hydrogen, blending Hydrogen into natural gas, is likely to occur perhaps sooner than that.

Joachim Wüenning (JW): Not really. I think a lot of things were said correctly and I strongly believe it has to come. If you believe in climate change, it must happen because we cannot use fossil fuels forever.

I also don’t believe that we will have an allelectric world. I don’t believe in nuclear power, so we cannot get all our energy from that, therefore, chemical energy carriers will be necessary for storage and long-haul transportation. Is it coming soon? Of course, it is hard to predict how fast it will be. Now, fossil fuel is cheap so it will be hard to compete with as Hydrogen is likely to be more expensive.

But certainly, what we see is the requirement from our customers to have Hydrogen ready burners. Because, if they invest in equipment at that point, why would they buy a natural gas only burner.

They should, of course, look for burners

which are able to do the transition without buying all new equipment again. So, we have a lot of projects momentarily to demonstrate the ability of the equipment to run with Hydrogen or natural gas and, preferably, not even readjusting the burners if you switch from one to another gas.

Perry Stephens (PS): I’ll try to add something a little different. At EPRI, we’re charged with providing the analysis and data from which other folks, like these gentlemen, are going to try to base important business decisions. Our work hasn’t focused specifically on Hydrogen, but, more generally, the class of alternate energy carriers – molecules, gas, or liquid – that can be produced in low carbon first energy ways through renewable energy sources. A lot of our work is focused on understanding the pathways from the initial energy which as a biomass source, solar, wind, could be nuclear, could be hydro. . . These sources of electric power that ultimately have to be used to produce this low carbon Hydrogen. One other

42 Furnaces International December 2021

pathway is Hydrogen or Hydrogenbased fuels produce the steam methane reformation process which uses a lot of hydrocarbons but would then require carbon capture and sequestration. The CO2 from these processes could be employed in a circular economy fashion.

So, we look at all of these.

The real challenge is the challenge of cost. How do you produce this Hydrogen or alternate fuel? And there are many other potential fuel molecular constructs that could be deployed. Ammonia is one being discussed in some sectors.

And then how do you transport them, store them, and what is their fuel efficiency and the cost of either new equipment or conversion of existing equipment to deploy those. We’re not specifically focused on Hydrogen. It is a very important energy carrier. It can be blended with fossil fuels in the near-term and then maybe expanded in the long term to higher percentages up to pure Hydrogen depending on the application, depending on where you produce it.

These costs must be evaluated and that is

a big job that we’re doing at EPRI with our LCRI initiative right now. We are trying to understand that techno economic analysis, that is, what makes the most sense for each sector of the economy.

WHY NOT ELECTRICITY? DG: Thanks, guys. Joe had mentioned global warming, a driving force here. Why not electricity? Why don’t we just convert everything over to electricity? Perry, you’re with EPRI, let’s start with you on that.

Instead of going just straight-out Hydrogen, why not just go to electricity?

PS: I think the question again rephrased might be, “when electricity and when Hydrogen” because I think that’s really what we’re trying to decide. There are interesting areas of research involving catalysis techniques that dramatically improve the net energy efficiency of chemical processes, for example, that might make direct electrification of certain processes more competitive. There are electric technologies for the low- to midrange temperatures that are attractive and use pieces of the electromagnet spectrum to produce transformation of products, heating and/or other transformations, that are very cost effective today.

So, we judge that a portion, maybe something approaching 30% of the remaining fossil fuel, could be electrified.

A certain chunk, a quarter, maybe reduced consumption through energy efficiency, 30% or more through electrification. It’s that difficult-to-electrify piece. Steambased processes and other direct combustion processes where electric technologies — for one reason or another, don’t look like they offer a strong solution, at least today — that we’re really concerned with. And, both in steam production and direct combustion of fossil fuels today, many cases we’re looking at having to have some sort of alternate combustible fuel.

JC: I’m not sure I completely agree with your question. In some ways, clean Hydrogen, or environmentally or low carbon Hydrogen, is electricity. It is simply a different means of storing electric power because the source of that is going to be some sort of renewable power, more likely than not, photovoltaics, wind, hydroelectric; those are going to be the electricity we use to break down the water

to generate the Hydrogen that we then go ahead and store. So, the alternative is whether we use batteries or Hydrogen to store this electricity and make it available either in a mobile setting, in a car or a truck, or off-peak times, at times when we are not able to generate electricity from renewables.

I think the question really is more along the line of end use. When are we going to be using electricity for the final end use?

We’re kind of process heating guys around this table. I think it’s going to come down to economics, for the most part. And I don’t think we’re quite there yet.

JW: Electricity is fine for some applications. I’ve driven an electric car for the last 10 years, but in long range, I drive the fuel cell Hydrogen car from my father, so different technologies for different purposes. There might be batch processes where I can have a break of a week if there is no sunshine and do the batch processing when electricity is available.

But if I have a continuous furnace with 100 megawatts which should run 365 days a year, it will be tough to produce the electricity constantly from a renewable basis to fulfill all these requirements. I think it’s just more economic and makes more sense to use the right technology for the right processes. It’s not an either/ or. Use the right technology for the right application.

BK: I would just back what Joe says. It can be selective to industry, the furnace type, or the type of material being processed. I know I’ve dealt in my career with a lot of the higher temperature-type applications — ceramics and heat treating and things of that nature. If you start getting above 2000 degrees Fahrenheit and up, and especially dealing with airspace, uniformity has a lot to do with it.

Electricity can be hard to get that uniformity without moving fans and having fans that operate at higher temperatures is another challenge. It’s extremely challenging and a big cost factor. What most people have said here is that it is probably not either/or. We see a lot of electricity being used but we’re fossil fuel burner guys, so we’re going to push that efficiency and that kind of cost.

You’re not going to want to miss the rest of this thought-provoking discussion.

A furnace manufacturer with a sterl L&L Special Furnace Co., Inc., is renowned for designing and building hightemperature furnaces, ovens, kilns, quench tanks and heat-treating systems, specialising in batch production furnaces and ovens with applications requiring high uniformity and controlled atmosphere. By Greg Lewicki* & Tom Schultz**

The company's humble origins began during World War II, with a need for a ceramics firing kiln in the city of Chester, Pennsylvania. The woman owner of a very small porcelain manufacturer asked her husband if he could help her find a kiln to fire her ware. Her husband, then working at a local shipyard as a welder, looked into the kilns that were available for that segment of the market and realised that there were not that many available and that perhaps he could make her one with the skills he had. Working with a friend from the shipyard, he made her a kiln and then other people, friends of his wife, asked if he could make one for them. One thing led to another, and soon the two friends quit their daytime jobs and started manufacturing hobby kilns in his garage.

And L&L Manufacturing Company was started.

Soon after, L&L became interested in industrial heat-treating furnaces, and a smaller division called L&L Industrial

Division started up. A few years later, the industrial division became L&L Special Furnace Company, a separate business.

In the 60 years since, L&L has earned a reputation for sophisticated engineering, quality workmanship, excellent documentation, and professional service.

The company offers a large line of heattreating furnaces in all different sizes, temperature ranges and capabilities, along with tempering ovens and quench tanks.

Everything is customisable On top of that range of product offerings, L&L Special Furnace Co. can customise and add accessories for each customer's unique needs. Various options such as circulating fans and heating zone control are available for tight uniformity requirements. Atmosphere gas control is available for either inert, reducing or oxidising requirements, and of course neutral hardening or carburising

atmosphere control is readily available as well. Any type of control and recording option is available, depending on requirements.

A value-oriented offering Over many years of development, L&L Special Furnace Co. has sought the best combination of features to promote precision, uniformity and value in its small bench-top furnaces. These are in demand across many industries, and for various applications and processes.

L&L Kiln Mfg., Inc., the successor to the old L&L Manufacturing Company, has had a strong presence in many hobby segments, including glass beads for the jewelry trade. In 1997, the two companies decided to work together to design and market a high-uniformity glass kiln with an opening at the bottom of the door to provide access for an operator to manipulate the beads inside the furnace on the hearth.

A SCIENTIFIC GLASS FABRICATOR’S TESTIMONIAL “L&L’s GS1714 is far and away the most dependable and robust scientific glass annealer ever built. I spent years using it for annealing glass instruments I built out of Pyrex, aluminosilicate, fused quartz… not to mention frit bonding optical components, slump testing exotic glass, firing precious metal lusters, and heat-treating metal.

The GS1714 stands out from the competition for two very compelling reasons: extremely smart design, and the most robust build of any scientific glass annealer on the market. That’s not hyperbole, it’s industry-proven reality, and the superiority of the design truly cannot be overstated. Any single feature on this furnace is enough to get excited for, and all combined, the GS1714 is so far ahead of the curve…. That’s all well and good, but let’s not forget the counterbalanced guillotine door equipped with an element cutoff switch for safety, 125-pound capacity in the firebox, constructed from heavy gauge steel, 2.5” (sic) thick firebrick backed with 2” of mineral wool to keep all your valuable heat inside the firebox where it’s supposed to be....”

The furnace had been shut down to carry out a cold repair and connected equipment.

The float glass line features hot oxy-combustion technology which uses 100% oxygen as an oxidiser instead of air, which results in a decrease in the melting energy consumption and a reduction of CO2 and NOx emissions.

A ribbon cutting inauguration ceremony took place on September 29 attended by managers, employees, the engineering team and overhaul suppliers.

LIBERTY STEEL UK RESTARTS ROTHERHAM GREENSTEEL PLANT LIBERTY Steel UK (LSUK) has relaunched production at its GREENSTEEL Rotherham electric arc furnace, with restart and operation at night to maximise efficiency and mitigate high energy costs.

Operations at Rotherham, which produces sustainably-produced steel for growth markets such as infrastructure and high-value engineering and is among the UK’s most electro-intensive industrial sites, are scheduled to run between 11pm and 6am when energy costs will be comparatively lower.

LSUK’s speciality steel division in nearby Stocksbridge which produces steel components for demanding aero-

space and energy applications, is also restarting focused production campaigns for key customers.

The restart, which LSUK plans to reach 50,000 tonnes per month as soon as possible, follows a £50mn funding injection from LIBERTY Steel’s parent company GFG Alliance, part of GFG’s restructuring and transformation drive following the collapse of its main lender Greensill Capital. The injection sets a stable platform for the full refinancing of LSUK operations.

LSUK plans to expand the Rotherham plant’s long-term capacity, ultimately creating a two million tonnes per annum GREENSTEEL hub with increased

employment and new products. Rotherham will supply LSUK’s downstream mills at Thrybergh and Scunthorpe which manufacture products for infrastructure, automotive and other sectors.

LIBERTY Steel UK’s Chief Executive Officer Subhajit Roy Chowdhury said: “As LIBERTY Steel UK ramps up we’re showing our commitment to make South Yorkshire a UK GREENSTEEL hub. LIBERTY is determined to support the Government’s drive towards a net zero economy and to make the decarbonisation of the UK steel industry a reality. We are committed to supporting the UK’s infrastructure growth plan.”

PLIBRICO TARGETS ALUMINIUM PROCESSORS WITH NEW

The Plibrico Company announced the introduction of Plicast Al-Rezist™, a line of low-cement, aluminium resistant refractories, to mitigate damaging and costly corundum growth in furnaces.

For aluminium processors, one of the costliest operational challenges in high production environments is the aggressive formation of corundum deposits in furnaces. Excessive, damaging, and costly, corundum growth can be mitigated with the right refractory materials, coupled with proper maintenance.

Plibrico’s Plicast Al-Rezist line of refractory materials are engineered for processors who run their aluminium melting and holding furnaces hotter and faster for extended periods of time, and therefore require superior aluminium resistant refractory performance.

“Due to robust demand, processors, foundries and die casters are operating furnaces at or above maximum production rates, leading to one of the industry’s most costly operational challenges: preventing corundum growth that will destroy a refractory lining,” explained Brad Taylor, President and CEO of the Plibrico Company. “We introduced Pli-

cast Al-Rezist to meet today’s need for a more resistant, longer lasting refractory that protects our clients’ furnaces from corundum and other destructive forces.”

Plicast Al-Rezist is strongly recommended for protection of the furnace hearth, lower sidewall and belly bands.

These areas of metal contact suffer the most mechanical abuse and metal penetration. The Plicast Al-Rezist line is produced with an enhanced multi-component package for exceptional performance against more aggressive alloys, including those with high fluidity. Developed with installation in mind, Plicast Al-Rezist is simple to apply with flexible options including Cast, Pump, or VibCast.

Engineered to resist corundum growth, thermal shock, and abrasion in extreme aluminium processing environments, Plibrico’s Al-Rezist line of castables offers superior aluminium penetration resistance and refractory performance. Extending the life of the furnace, maximising production uptime, and keeping downtime and repairs to an absolute minimum.

FORGLASS HAS ANNOUNCED THE LAUNCH OF A DUAL MELTING FURNACE Forglass has announced the launch of a furnace that can simultaneously melt two or more different types of glass.

Merging the need to quickly implement changes in production schedule involving different glasses with the desire to maintain the highest possible melting efficiency for as long as possible in one furnace is difficult, often impossible.

The Forglass MultiGlass furnace has been designed to simultaneously produce smaller volumes of two or even several glasses with energy consumption comparable to melting only one glass in

a standard, single-tank furnace.

Lower energy consumption per ton of glass also reduces the emission of environmentally harmful compounds (CO2, NOX, SOX), and eliminates reject of glass that is unsellable due to its undesired properties or quality, but has to be produced when changing the glass composition in the furnace ‘on-the-fly’.

The Forglass MultiGlass furnace is the ideal option for both greenfield investments and modernisations in restricted spaces.

For many glassworks located in urban areas, this opens up new opportunities

for expansion or restructuring of their production capacities.

Conversion of a standard furnace into the Forglass MultiGlass furnace can be carried out in any glassworks by expanding the furnace (adding a second tank) only in its width, not length.

It is generally the only space available in the production hall and, what’s crucial, the expansion of a U-fired furnace does not involve radical rebuilding of the regenerator, which makes it inexpensive and fast.

Life of a Furnace

Advanced modelling to speed up th technologies in the manufacturing o temperature performance furnaces

By JiaYi Yan* and Mustafa Megahed** Sustainability is nowadays a keystone in industrial furnaces working at high temperatures (>900ºC) linked with energy and spare parts consumption.

Many of the components inside these furnaces comprising rails, beams, rings and rolls among other are responsible of transporting the product during their working routine. Many of these components are metallic due to their unique combination of high temperature properties such as thermal fatigue, thermal conductivity, creep, oxidation, wear and ductility. Refractory stainless steel alloys are by far one of the most extended alloy grade used for this porpoise due to the their balanced price and performance condition. However, their degradation with time is evident and the replacement of components has a significant impact in energy efficiency of furnaces due to programed or nonforecasted stops and in raw material consumption due to a significant rate in components replacement.

New advances in digitalisation through modelling and in new manufacturing techniques allow to step up in a new scenario, where materials and new processes for the manufacturing of components can be developed more precisely and fast from design to validation.

The use of bulk materials highly alloyed can be substituted by using low alloyed substrates and applying a high value-added layer of mms with high wear and creep performance properties. One ring located in a hot stamping furnace that transport parts inside it, supports temperatures in the range of 930-950ºC, oxidant atmospheres and loads. Current

he integration of new materials and of components for their use in high failure modes of these rings are creep and a combination of wear and oxidation.

The geometry of this ring is adequate to

substitute the bulk material by a hybrid component comprising a refractory stainless steel alloy with a surface layer

Figure 3: Predicted variation of liquidus and solidus temperatures for the maximum and minimum limits of each element in the Haynes 230 alloy specification

Figure 4: Scheil (solid) and equilibrium (dotted) solidification ranges for the nominal composition of Haynes 230 without (green), average (black) and with maximum (red) amount of impurity elements (Fe, Co, Cu, Ti, B)

of Ni alloy, e.g., Haynes 230. The layer can be applied via laser metal deposition (LMD), for example.

Using a CALPHAD-based materials modelling approach in the framework of HIPERMAT - H2020 -GA- 958196 project, it is possible to extend upon the experimentally available data and provide properties in a wider temperature range while capturing the influence of chemistry variations on thermodynamic properties such as specific heat, liquidus and solidus temperatures and latent heat, but also physical properties such as density, thermal conductivity and liquid viscosity as shown on Figure 1.

Material datasheets for Haynes 230 contain useful data, such as the specific heat from room-temperature to 1000 ºC, covering the most common application temperatures for the alloy. However, for liquid- and solid-state process simulations, a wider temperature range is needed. For example, by calculating the specific heat (not accounting for latent heat during phase transformations) of the nominal composition of Haynes 230 (average content of all alloying elements listed in Table 1), the experimental specific heat is well-replicated in the lower temperature range. Furthermore, the available temperature range for this important material parameter is greatly extended to cover not only the solidification range, but also the hightemperature melt. Figure 2 shows the CALPHAD-predicted and datasheet values of the specific heat, respectively.

Another example of the usefulness of a CALPHAD-based modelling approach for material parameter determination is the sensitivity of equilibrium solidification range to alloy chemistry within the specification listed in Table 1. Possible batch-to-batch solidus and liquidus temperature variations based on thermodynamic equilibrium calculations using Thermo-Calc software and the TCNI database, within the specification

Figure 5: Example thermo-physical property prediction variations

Figure 6: Example output from process simulation showing the melt pool and heat affected zone dimensions in meters during LMD deposition

are shown in Figure 3. The liquidus temperature varies in a rather narrow temperature range (~20 ºC) whereas the solidus temperature is highly dependent on the impurity content and varies by up to 60 ºC. Additionally, the influence of processing route on the relevant material parameters (in this example the solidification range) should not be neglected, especially for manufacturing routes with rapid solidification (e.g. casting, welding, LMD/additive manufacturing), since rapid solidification causes elemental segregation in the microstructure, which in turn influences the solidification sequence and the corresponding solidification temperature range. Figure 4 shows an example of equilibrium (dotted lines) and Scheil solidification (assuming no diffusion in solids, full lines), where the Scheil solidification range for the nominal Haynes 230 composition (black) is extended by nearly 100 ºC compared to the equilibrium solidification range.

impurity elements on the solidification range is shown by the green (no impurity elements) and red (maximum impurity content) lines. Figure 4 In addition to composition variations, differences in CALPHAD databases also lead to variations in predicted properties.

Figure 5 shows the calculated density and solid fraction functions for two choices of composition and CALPHAD database, to demonstrate variance.

Variant 1 is from Pandat database, while Variant 2 is from Thermo-Calc database TCNI11 using a different composition.

The predicted properties exhibit some differences, though the general ranges and trends are in agreement.

Using the computationally predicted

materials properties as input, LMD process simulations were carried out. Figure 6 shows the temperature distribution in space, from which the size and geometry of melt pool, can be visualised. Figure 7 shows the temperature history of a monitor point, using the Variant 1 dataset. The material undergoes multiple heating and cooling cycles as the heat source approached, processes and then moves away from that point.

The variations in calculated properties result in different cooling profiles during solidification. A metric derived from the cooling profile is the so-called “cracking susceptibility coefficient” (CSC), defined

by Clyne and Davies as the ratio of time spent in the “vulnerable” interval to

While the empirical metric bears some arbitrariness and can only be used for rough comparison purposes, the LMD simulation clearly provides more information on solidification process and realistic cracking tendency.

The influence of chemistry variations on solidification becomes increasingly important when modelling the entire LMD process on a steel substrate, where mixing at the substrate/coating interface will significantly change the alloy composition. The alloy composition variation across the interface, as well as the length-scale that is affected will depend heavily on both substrate composition and alloy composition, as well as process parameters (laser power, scanning speed). Depending on the amount of alloy mixing, a different set of material parameter may be needed to provide reliable process simulations for. Similarly, if the selected alloy does not meet the property targets or the performance goals in the LMD-processed condition, the alloy composition may need to be optimised for improved asdeposited mechanical properties, or even replaced with another alternative. Any process parameters developed for Haynes 230 (or other coating) would then need to be re-optimised for the new substrate alloy chemistry, which in turn would influence the as-deposited mechanical properties of the deposited coating alloy.

This closely connected loop of alloy and process optimisation, and the associated material and process modelling, can be described in a “combined material and process modelling framework”, as outlined in Figure 9.

As the HIPERMAT project develops, and experimental results for the benchmark materials become available, the intention is to take this another step. By utilising the optimised process parameters and the resulting simulated temperature-time profiles as input for modelling of LMDdeposited coating on a steel substrate, the alloy’s microstructure will be determined and mechanical properties predicted. This ultimately allows for upfront evaluation of the alloy’s properties and their chemistry optimisation to meet the property requirements of the final components in the hot stamping furnace. �

BatchPilot fu increasing ca production g BatchPilot furnace major upgrade A top-selling furnace weighing system from Aluminium Casthouse Technologies (ACT) is embracing the advance of Industry 4.0 with a major IT upgrade.

The BatchPilot, an innovative technology used in casthouses worldwide to accurately measure furnace liquid metal weight and determine exactly what is wanted aluminium and unwanted dross, is now installed with the latest Siemens S7 central processing unit and software for an even more accurate online process data logging and more userfriendly smart screens.

The upgrade of the Batchpilot system will, ultimately, allow customers to achieve greater gains in productivity, leading to even higher production levels at a time when the London Metal Exchange is rising sharply.

Managing director John Courtenay said: “Knowing the correct weight of metal in the furnace is crucial to ensure slabs are consistently cast to the precise length ordered by the customer. The BatchPilot means casthouses don’t have to rely on visual estimates of furnace heel weight, which are notoriously unreliable, often leading to short casts, overfilling of the furnace or potentially restricting the number of slabs cast, all hugely wasteful.”

He continued: “Bringing an overall increase of more than 15% in production without the need to install new capacity, the system is an invaluable addition to the casthouse and this IT upgrade embraces the spirit of Industry 4.0, making operations even more efficient and improving the user experience.”

The BatchPilot uses unique technology for the accurate electronic measurement of furnace heel weights and transfer

urnace weighing system for asthouse productivity and gets major IT upgrade weights and is based on the principle of measuring changes in the furnace hydraulic cylinder pressure with furnace tilt angle. This allows precise measurement of furnace liquid metal weight, heel weight and dross build up.

Increasing ‘right first time’ batching, other benefits include increased number of ingots per cast, elimination of short casts, increase in yield due to reduction in overlength casting and energy savings due to reduced furnace waiting times.

Easily fitted to existing furnaces without interruption of production, it is a simple, fully automated, retro fitted device that is fully integrated into the batching process.

In terms of return on investment, with prevailing premiums, the payback time for a BatchPilot fitted on a 70MT furnace is less than three months due to the productivity gains it brings.

Crucially, the system – which has successfully been in production usage for over 10 years with fifty five units installed in casthouses around the world - can be tailored and customised to individual customer needs.

ACT is owned and managed by the Courtenay family, also shareholders and directors in aluminium grain refiner producer MQP. MQP’s parent company is Sitong Group, one of the largest producers of master alloys in the world and manufacturer of MQP’s high efficiency Optifine grain refiner.

As well as the BatchPilot, ACT provides the aluminium industry with a range of well-established casthouse products including Refinal fused fluxes and Casiflux environmentally-friendly launder coatings, together with comprehensive back-up support through distributors, agents and technical personnel. �

Tenova TRGX regenerative and TRG burners: The reliable technology for reduction through improved combu

By Michele Roveda* and Davide Astesiano **

Introduction The current discussion about energy transition and transformation of the steel industry into a climate-neutral sector by 2050 is mainly focused on the decarbonization of steel production, where fossil raw materials and fuels contribute to the CO2 direct emissions.

In hot rolling processes, fossil feedstock is used as a fuel and it is responsible for the carbon footprint of final steel products from about 100 to 250 kgCO2/tCS respectively for billets and plates.

In order to be in line with industry’s long-term vision and to contribute to the worldwide general targets of GHG emission reduction, it will be of fundamental importance to adopt a holistic approach that includes low carbon technologies for heating processes associated with the steelmaking downstream furnace operations.

The availability of green electricity is of course crucial to this end, both to reduce emissions and to produce green fuels such as hydrogen in order to replace fossil sources.

As green fuels are still not giving enough returns in terms of profitability besides hydrogen availability which remains still to be exploited, an immediate step towards decarbonisation can be considered in the new capital investment by adopting those technologies which assures the highest level of fuel efficiency which is mainly reached by increasing the combustion air temperature recovering the residual heat stored in the waste gases.

These technical goals motivated

Tenova, a leading developer and provider of sustainable solutions for the green transition of the metals industry. To develop the regenerative and selfregenerative burners which were released in early 2008 . Since then more than 500 regenerative/self-regenerative burners have been installed at nine different industrial plants.

Tenova’s approach to being a valuable partner in providing sustainable solutions for end users is part of the continuous development strategy towards the next generation combustion systems: a comprehensive approach to sustainability providing the combustion system with hydrogen ready burners, smart equipment for a flexible operation obtained from the synergy between automation process control and AI platform based algorithms. The most recent Tenova SmartBurner platform installation represents the framework in which IoT solutions are leveraged in order to monitor and improve key performance indicators (KPIs) and key health indicators (KHIs) of each single burner unit.

Technology assesment There are several drivers that are considered during the assessment phase for a new installation or plant modernisation combustion system technology project. Ultimately, the selection of the combustion system is based on the key drivers of high target product quality, minimum energy consumption, compliance with environmental regulations, and the

achievement of minimum CAPEX. Minimum energy consumption is normally synonymous with minimum OPEX. Regenerative burners work in pairs (see Figure 1) with typical cycles of about 60 secs, and are controlled by automatic valves installed into the piping lines.

They are able to preheat combustion air up to 1000 - 1150 °C for reheating process while for self-regenerative burners used in heat-treatment the air pre-heat is up to 750 °C. Considering the fixed furnace length, the regenerative systems are able to provide higher available heat to the process thus implying a productivity improvement of about 20 - 25%. This is particularly effective for plant modernisation where a significant increment of production rate can be achieved while minimising the impact of the revamping operations.

In the other hand, a regenerative furnace is 20-25% shorter in length than a conventional one and the higher available heat to the process implies areduced fuel consumption thus the carbon footprint is significantly reduced.

The regenerative burner combustion system are an immediate solution to reduce CO2 emissions of about 10% compared to CO2 emission rate of recuperative systems which is today the largest adopted technology on hot rolling mill and heat treatment lines.

CO2 emission drops immediately despite the availability of green fuel hydrogen which today is still a crucial issue for steel plants. The Tenova Regenerative

burners are hydrogen ready so whenever green hydrogen becomes available in the fuel network an additional significant step towards decarbonisation (eventually reaching zero emissions) can be achieved by the end users The increasing of combustion air temperature in high efficiency furnaces means a sensible increase of NOx emissions, especially in the case of hydrogen fuel pure or mixtures having high hydrogen content: The effect of hydrogen is to reduce the flame length, higher intensity implying higher peak temperature which enhance the NOx formation reactions.

For this reason, Tenova regenerative burners adopt flameless technology to reduce temperature peaks and reduce NOx emissions.

Tenova tradition on regenerative burners Tenova has a long tradition in leading edge combustion technology and developed an interdisciplinary design process including Computation Fluid Dynamics (CFD) modeling, industrial scale test and industrial applications.

The consolidated workflow (figure 2) allows Tenova to drastically reduce the time it takes to develop new burners and combustion systems for the market.

Experimental tests are also focused on providing reliable and high endurance equipment, which are of paramount importance to assure combustion performances. In fact, the high combustion air temperature reached inside the regenerator requires a precise design and material selection for the

internal refractory lining. Similarly, the automatic valves and field equipment to properly control the cycling operations between the two subsequent working modes (firing-regeneration) have to provide top operating and long lasting performances keeping into consideration the extremely high amount of manoeuvres which are required during the burner lifetime.

Subsequent to the tests, the test campaign on full-sized industrial furnaces was done from 2008 to 2010 by replacing some burner units on existing recuperative type furnaces. Two different types of regenerative media for combustion air have been assessed: honeycomb type and ball type. The honeycomb is suitable for clean fuels and clean furnace chamber atmospheres

while the latter can be adopted where dust and gases contamination is present.

While TRGX are used in reheating furnaces, for heat treatment furnaces Tenova has developed, in 2012, TRGSX self-regenerative flameless burners. These burners adopt the same concepts of the regenerative type provided that a double set of regeneration media is installed on the unique burner so the regeneration of one set of media is done in the burner while the burner itself is firing using pre-heated air from the second set of regenerative media. This allows the burner to always be in operation with the drawback of an increased complexity of the burner system.

The portfolio was enlarged in 2015 by the double regenerative burner, TRGD, which is able to preheat both air and gas by using two different regenerators. The TRGD are suitable for the application where the gaseous fuel has a low net heating value as for example Blast Furnace Gases where increasing the flame temperature is necessary. It is important to underline that the burners are able to work with BFG starting from cold conditions assuring extremely low CO emissions.

“Lowering the impact on the environment, maximizing efficiency and energy saving have been the drivers for several investments in Tenaris for the last years. The self-regenerative technology for heat treatment furnaces and the regenerative technology for rotary furnaces developed by Tenova were a perfect fit for our new Pipe Mill in Tenaris Bay City, TX, USA. “, says Luca Benigni, Engineering Senior Director - North America from his office in Tenaris’ America Engineering Department. He continues “The use of Tenova burners allowed us to achieve in the Mill best in class efficiency values and lower CO2 and NOx emissions.

For the years to come, Tenaris will remain committed with environmental footprint reduction of its industrial activities, including a firm commitment to reduce CO2 emission by 30% within 2030. Having reliable partners such as Tenova for the development of new and more efficient combustion technologies, including hydrogen, will be a key element to achieve this goal.”

After some years of operation of regenerative technology burners in Bay City, Dalmine and several other furnaces in Tenaris industrial systems, the technology has proven to be mature and providing the expected benefit in terms of consumption and emission reduction.

Considering the complexity of the regenerative system, for maintaining burner performances at nominal levels throughout its life, in recent years Tenova has introduced the concept of SmartBurner where the burner status is monitored, controlled and integrated with the furnace process parameters.

The SmartBurner IIoT framework offers a complete set of process diagnostics, KPIs and KHIs that allow controlling the status of important process burner parameters (i.e combustion ratio, leakage of switching valves, combustion quality) and carrying out easier burner inspection and maintenance interventions.

Process performance measures and health status of single critical components can be continuously monitored with the final aim to simplify and support any personnel intervention on field.

The recent development program relates to the optimisation of regenerative burners powered with hydrogen or with natural gas and hydrogen mixtures.

The flexibility of the hydrogen ready burners permits to maximise the consumption of the available amount of hydrogen on Customer plants through www.furnaces-international.com

the possibility to work with variable mixtures of NG and H2.

The optimised hydrogen flameless combustion allows maintaining NOx emissions always below the future stringent limits (< 80 mg/Nm3) in combination with a potential carbon free quantity of waste gases.

Operation results Since the first industrial installation of a whole furnace combustion system made by regenerative technology in 2009 till 2019 more than 600 Tenova TRGX regenerative and TRGSX selfregenerative flameless burners units have

been put in operation contributing to an approximately reduction of 250.000 tons of CO2, as summarised in the Table 1 and Table 2.

Conclusions Many well-known potential drawbacks (cost, complexity, control) that affect implementation of regenerative burner technology, are now being overcome

by Tenova, with specific technological solutions, such as flameless technology, correct material choice, burner design, control strategy, and overall furnace design, from knowhow derived from more than 40 years’ experience.

Tenova regenerative flameless burners combine the lowest NOx emission level with high temperature combustion air preheating, which allows an important reduction of CO2 emissions through high combustion efficiency. Hence the sustainability of the steel plant can be immediately improved even for those sites where green hydrogen is not available yet, keeping into consideration that the Tenova burners are hydrogen ready so whenever hydrogen will be available a further step towards carbon neutrality can be taken without any modification to the burner. �

VALMIERA GLASS INVESTS €9 MILLION IN LATVIAN FURNACE Latvian glass manufacturer Valmiera Glass has completed an extensive reconstruction of its glass melting furnace.

The group invested €9 million of its E-glass melting furnace no 2.2 which it aid would improve the production quality of the furnace and make it more efficient and climate neutral.

The E-glass melting furnace will allow the company to ensure stable supply and delivery of E-glass and its products to the global glass fibre market.

The furnace is expected to reach full capacity by October with gradual production expected to start this month.

Stefan Jugel, Chairman of the Management Board, said: “With the help of our shareholders and our financing partners, we have managed to terminate the LPP early and put the company on a solid financial basis. The switch to investment and growth is now the logical step to make us as a reliable, European manufacturer even more attractive for our customers. We have already started further investment projects in order to meet the

market requirements in 2022 and the following years.”

A new automatic control system was installed for E-glass melting furnace No. 2.2, its electric heating furnace was completely reconstructed in the melting section, and the electric melting capacity was increased to reach EU natural gas consumption and CO2 reduction targets.

The furnace also has a new recuperator for recovering the heat from exhaust fumes, as well as a new filter for the exhaust fumes. In parallel, it has also reconstructed the indoor climate maintenance system and made investments in the glass fibre bobbin storage and maturing system that ensures higher manufacturing quality. The company invested an additional € 1.9 million to complete these works.

Girts Vèveris, Management Board member responsible for production, said: “By reconstructing furnace No. 2.2, we not only want to become technologically advanced, but also to protect the

environment, and become as climate neutral as possible in our core business.”

He continued, “These improvements allow us to take a few steps towards this goal: with the new recuperator, we will be able to recover more heat from the exhaust fumes of the furnace, and heat the production facilities instead of the outdoor air.

Thanks to the higher electric melting capacity, we will consume less natural gas and produce fewer CO2emissions.

Moreover, the reconstructed climate maintenance system will increase the quality of our products, as well as considerably improve the working conditions of our employees during the warmer months of the year. It will also allow us to use energy sources in a more rational manner.”

Glass melting furnace No. 2.2 features an approx. 35m2 basin, and its maximum production capacity is up to 50 tonnes of E-glass fibre per day. The glass melting furnace is expected to have a 10year life cycle after the reconstruction.

ARCELORMITTAL BELGIUM ANNOUNCE PLANS TO REDUCE CO2 EMISSIONS BY 3.9 MILLION TONNES PER YEAR BY 2030 ArcelorMittal has announced that it has signed a letter of intent with the Governments of Belgium and Flanders, supporting a €1.1 billion project to build a 2.5 million-tonne direct reduced iron (DRI) plant at its site in Gent, as well as two new electric furnaces.

The two electric furnaces will melt the DRI and scrap steel, which will then be transformed in the steel shop into steel slabs and then further processed into finished products. The furnaces will be able to take waste wood and plastics as a substitute for fossil carbon.

Once the DRI and electric furnaces are built, there will be a transition period during which production will move gradually from blast furnace A, to the DRI and electric furnaces, after which blast furnace A will be closed. By 2030, this will result in a reduction of around three million tonnes of CO2 emissions each year.

The DRI plant will operate alongside Gent’s blast furnace B, which restarted production in March 2021 following a significant investment of €195 million.

Various decarbonisation initiatives, including the commissioning in 2022 of Gent’s Steelanol/Carbalyst and Torero projects will see annual CO2 emissions reduction of 0.9 million tonnes by 2030.

The combination of the new DRI plant alongside a sustainable, stateof-the-art blast furnace enables the creation of unique synergies in ArcelorMittal Belgium’s roadmap to climate-neutral steelmaking.

The hybrid model approach of Smart Carbon and Innovative DRI steelmaking in Gent fits into ArcelorMittal Belgium’s CO2 roadmap (more information can be seen via the link below).

Alexander De Croo, Prime Minister of Belgium, commented on the plans: “To tackle the climate crisis, we need ambitious action. European countries are leading the way, with clear targets

to reduce greenhouse gas emissions by 55% by 2030 and climate neutrality by 2050. It is good to see that sectors with a large footprint are also joining the race by investing in innovation that reduces emissions and, in the long term, achieves carbon neutrality. This major investment in new technology by ArcelorMittal is important for the wider Ghent region, for reducing our country’s footprint, and shows that decarbonising our economy is a joint effort.”

ment and Belgian Minister of Finance, added: “In order for us to enable climate transition for a better, healthier tomorrow it is crucial for government and industry to come together in this crucial pivoting point in time. ArcelorMittal is proving to be a leading example for this transition in our region. This joint effort is not only securing the presence of ArcelorMittal in our region but is also quintessential in lending the Ghent region healthy & clean air for all.”

Aditya Mittal, CEO, ArcelorMittal, said: “Today’s announcement is the third major decarbonisation project we have announced in the past two months, demonstrating how we are taking firm steps to decarbonise our operations

ment in order to accelerate ArcelorMittal’s journey to net-zero steelmaking.”

Manfred Van Vlierberghe, CEO, ArcelorMittal Belgium, said: “ArcelorMittal Belgium has a passion for sustainability and circularity. We continue to invest and launch new projects in order to remain at the forefront of energy and climate transition. This €1.1 billion project is a major milestone in our decarbonisation journey. The DRI plant and two electric furnaces will result in a sharp decrease of CO2 emissions while the relined blast furnace will contribute to recycling waste wood and end-of-life plastics. This approach contributes to strengthening our global leadership in terms of CO2 and energy efficiency in the steel sector.”

PILKINGTON RUNS FURNACE ON HYDROGEN IN FIVE-DAY T Pilkington UK used a blend of hydrogen and natural gas to run its Greengate furnace in Liverpool during a five-day trial.

The trial found that a full furnace could be run safely on the hydrogen blend, without comprising quality or performance. Each day of the event, two tonnes of hydrogen were consumed

– enough to provide an equivalent hydrogen blend for approx. 30,000 average-sized homes.

The event marked the latest demonstration of a UK-wide roadshow led by the Decarbonised Glass Alliance (DGA).

Launched earlier this month, the national tour will run until 27th October,

ending the weekend before the UN Climate Change Conference (COP26) in Glasgow.

The tour has illustrated the role hydrogen has to play in assisting the UK’s target of zero net carbon emissions by 2050.

MATERIALS PROCESSING INSTITUTE WELCOMES SELECT COMMITTEE’S SUPPORT FOR HYDROGEN AND ELECTRIC INNOVATION TO DECARBONISE UK STEELMAKING Materials Processing Institute to decarbonise UK steelmaking The Materials Processing Institute has welcomed a recommendation to the UK Government to “commit to a pilot of hydrogen-based steel production in the UK as part of its industrial decarbonisation strategy”.

Chris McDonald, Chief Executive of the national steel innovation centre gave evidence to the Department for Business, Energy and Industrial Strategy (BEIS) Select Committee, in addition to the Institute’s formal written evidence.

It follows publication of the Teesside-based Institute’s “Decarbonisation of the Steel Industry in the UK” paper in March 2021.

Jointly authored with industrial consultancy, Syndex, it made a series of recommendations about how the decarbonisation of the steel industry provides Britain with an opportunity to stimulate domestic production and take a lead in the new Green Industrial Revolution.

Chris McDonald said: “Delivery of a DRI-hydrogen based solution alongside electric arc furnace technology for steel decarbonisation would enable Britain to deliver the net zero ambitions coming out of COP26 whilst allowing a smooth and just transition for the workforce.

“Speed is of the essence and an industrially-focused innovation strategy accelerating pilot and demonstration facilities will enable British steel producers to catch up with competitors in Sweden, Germany, Canada and even China.

The Prime Minister is right to describe UK steel as a “great national asset” so getting this right is essential to deliver the Green Industrial Revolution.

In-Furnace Radiometric Thermal Imaging to reduce specific energy and carbon dioxide (CO2) Christopher Leonard*, and Neil Simpson** review the potential of in-furnace radiometric thermal imaging to reduce the specific energy of industrial applications and start the decarbonisation journey.

The road to sustainability for many energy-intensive industrial processes is a major challenge; however, it can be broken down into more manageable steps.

Radiometric thermal imaging can optimise aspects of combustion and thermal process dynamics to improve product quality and yield while reducing specific energy consumption and

extending asset life.

In most industrial furnace applications, whilst the energy balance is complex, it can be simplified to � Energy In = Energy to Process

+ Stack Loss + Additional Loss (such as through walls) In many applications, the Additional Loss is almost constant and is the zero-product or “hot-hold” energy requirement.

Assuming this loss is constant, then if more product can be made (to the same quality and specification), the specific energy or Joule per Tonne decreases as the constant loss is spread over more product. A worthy goal, which by default also reduces CO2.

High-definition radiometric thermal imagers, including the Near Infrared (NIR-B) and Medium Wave Infrared (MWIR-B) borescopes, can provide new levels of thermal data and insight to troubleshoot and optimise furnace operation and design.

Examples An early example of the potential of infurnace thermal imaging came from surveys on Steam Methane Reformers (SMR), which are used in the industrial production of hydrogen, which is now projected to be a decarbonised fuel of the future.

A radiometric thermal survey or fixed installation can provide critical data and insight into the condition of the reformer tubes, highlighting tell-tale hotspots that could indicate an imminent breakout or provide greater confidence to run the process at a higher temperature and

closer to optimum efficiency. Insight and actionable data enable small changes to deliver large returns, avoiding unexpected costly shutdowns or maximising yield, quality, and thermal efficiency. Figure 1 The potential scope of work is significant, and the challenge is deciding what to look at! The NIR-B imager is assumed by many to be an incredibly clear CCTV image and “pretty picture”.

This is not the case - with more than 324,000 radiometric thermal data points in one frame (nearly 3 million data points for the 2K model), it becomes evident that identifying critical areas and fully utilising this data needs planning and process.

Considering this thermal data in a similar manner to that offered from a Computational Fluid Dynamic [CFD] model may be beneficial. Indeed, the data from an in-furnace thermal survey can be used to validate CFD models.

When you have a validated CFD model, you can investigate optimisation and the impact of making modifications for decarbonisation, such as firing with hydrogen or a renewable biofuel.

Monochrome black and white (B&W) has been the pallette of choice for many years, since it has the maximum contrast and offers the chance to best use specific temperature isotherms. In the biomass application in Figure 2, there is the opportunity to set high-temperature isotherms to track the movement of the

charged fuel.

This high-definition radiometric thermal data enables operators to optimise fuel flow rates, monitor tube fouling, receive alerts on process parameters and alarms for critical refractory damage.

In essence, it provides a clear view and precise measurement of previously ‘dark or obscured processes’ to enable better process and asset management.

Figure 3 shows 62*1.5° isotherms of the surface temperatures of the billets in a walking beam steel reheat furnace. The impact of the water-cooled skids is evident and offers the opportunity to validate the model-based predictive control system to optimise energy for existing fuels. The billets are cooler at the near side. A hotter leading edge should reduce the risk of damage/interruption to the first pass breakdown roller. Moving the camera to the discharge end shows the maximum surface temperatures, and ensures that the steel is not overheated to the point where the resulting product is scrapped.

Conclusions Taking the first steps on the road to decarbonisation can be daunting; however, the high-definition thermal data provided by the latest radiometric thermal imagers offers a powerful tool to guide process changes and help optimise and automate many aspects of furnace operation and thermal process.

The net results speak for themselves:

THE SURVEY In most industrial combustion applications, an organic (Carbon-based) fuel is used, with CO2 a product of combustion. Therefore, any energy usage reduction reduces CO2 production. For many, this is the obvious and best starting point. A thermal survey can identify cold spots that may suggest over-cooling or where additional insulation could be beneficial. It could also suggest a hole in the refractory or exposure of water skids. Early identification of refractory issues can make a repair easier, lower the repair cost, and reduce or avoid the high cost of lost production.

Long-term asset protection impacts plant viability and decarbonisation relating to the manufacture of refractory components.

The NIR-B imager has been used to supervise ceramic welding, furnace cool-

increased yield and quality, reduced emissions, asset life extension, and reduced fuel consumption. This is good for the bottom line, and also an important debit in carbon accounting.

Sophisticated thermal imaging equipment that has been made rugged for use in arduous industrial environments needs a robust investment justification, and therefore, to enhance fixed installations and provide an introduction to high-definition radiometric imaging,

down and heat-up to reduce downtime.

While many initially look at energy in isolation, the specific energy (energy/ unit) is a better measure and focus for the decarbonisation potential.

If the thermal survey identifies the source of a defect, such as over-heating a steel billet, then the quality and yield of the products improve. The ability to sell a product instead of scrapping or using energy to re-work/recycle dramatically reduces the specific energy. This is the fastest return on investment of any survey. Once you have optimised for quality/yield, there is the potential to increase throughput, provided there is forming/rolling capacity and market demand/storage. Typically, there is an increase in total energy; however, the specific energy and CO2 reduce, since fixed

energy losses, such as wall losses, spread over more products produced.

It is anticipated that an in-furnace thermal survey has the potential to be included as part of an ESOS furnace audit or part of a company’s ongoing ISO50001.

The quality and amount of data that can be measured and recorded during a survey is contingent on suitable access, site preparation, and the quality of utilities (air, water etc.) available. Preparation is key to obtaining good data. Typically, the larger the furnace and the more viewing locations, the longer the process takes. For extended surveys or hot regenerator repairs, semipermanent installs with an auto-retraction system may offer a better solution.

Improving safety, emissions rates a safety shut-off technologies ASCO™ 158/159 Series Motorised Double Safety Shut-Off Valve

By Asaël Hervet-Binois* Two of the highest priorities across today’s furnace industry are protecting people and the environment. Facilities that use furnaces for heat-treating processes, including melting, smelting and reheating furnaces or vertical hearth, galvanizing and surface treatment furnaces, seek solutions that offer better combustion safety and energy efficiency.

Manufacturing and operating furnaces that are safer and produce fewer emissions

start with specifying components that improve safety and energy use.

There may be no components in a furnace fuel train that are more important to safety than the safety shut-off valves.

These elements either block or allow fuel to flow between the source feed and burner, and their function and design can influence the reliability and performance of the furnace overall. If safety shut-off valves perform optimally, they can help

conserve energy and save lives. If they do not perform as required, the results can range from inefficiencies in combustion drives and increased fuel consumption to life-threatening explosions.

Because of their critical role, safety shut-off valve technology requires careful selection. There are many options to choose from. The latest advancements in safety shut-off valves help manufacturers design and end users operate reliable

and energy efficiency with the latest furnace fuel trains that use less energy.

A new generation of safety shutoff valve technologies offers greater temperature ranges, higher pressure ratings and improved product capabilities and meets key global standards and regulations. Their specification in furnace fuel trains can optimise furnace performance, significantly improving safety and energy efficiency in addition to reducing emissions.

Higher fuel flow rates, faster valve response times Heat-treatment facilities use a substantial amount of energy to produce their products. To save energy, these facilities look at both process and facility energy consumption to determine where losses may occur. When facilities use energy inefficiently, high emissions can result.

To help save valuable energy and lower emissions, it’s important to consider the safety shut-off valves in the fuel trains of boilers, ovens and furnaces.

Safety shut-off valves provide on/ off control to completely stop the flow of fuel and high/low/off control to modulate valve status from fully open to fully closed. Component designers have engineered new, motorised safety shut-off valves to achieve higher fuel flow rates, which can improve energy efficiency as well as furnace performance.

Optimised curvature, volumes and capacities can achieve higher flow through the valves as well as the fuel train at large. These updates take into consideration the devices along the fuel train that slow fuel flow or change the pressure profile, resulting in pressure drops. The traditional double safety shutoff valve, for instance, is responsible for 65% of pressure drop incurred. Higher flow rates significantly reduce pressure drop, even when inlet pressure is low, to adequately maintain fuel flow.

This makes it possible to generate greater heat output and allows burners to function at a set higher turndown ratio, which reduces the number of stops and starts and, in turn, fuel consumption and emissions. It can also improve load control and even extend burner life.

Selecting motorised safety shut-off valves over solenoid-activated on/off valves can also save energy. Motorised valves offer greater flexibility with placement in the low or high fire position.

Instead of wasting energy by fully firing the burner when demand doesn’t require it, the actuator can modulate valve opening and closing to better meet demand and optimise energy use.

The latest pneumatic piston safety shut-off valves feature very fast response times that enhance pulse-firing

fuel consumption and the emissions that result.

Durable valves that open and close the fuel line quickly are preferred in these applications due to cycle frequency. Some valves may cycle 500,000 times per year.

It’s important that the valves chosen for these applications have a very long lifetime and cycle quickly.

With improved flow, these valves can also handle a range of fuels and other media at pressures up to 25 bar (360 psi), including coke oven gas, vacuum, oxygen, steam or hot water, hydrogen, ammonia, nitrogen and oil.

Compared to conventional pneumatic ball valves, the latest pneumatic piston valves consume less air, and have a lower actuator volume, than conventional pneumatic ball valves. They also have a smaller footprint and longer expected lifetime.

Higher pressure ratings and greater temperature ranges

Asaël Hervet-Binois is product marketing manager of Combustion, EMEA, at Emerson. He serves different customers and applications in the field of heat treatment, including petrochemical furnaces; process boilers; thermal oxidizers; industrial and commercial burners; and metal, ceramic and glass furnaces. https://www.emerson.com/en-gb/automation/solenoids-pneumatics/asco/combustion-solutions Image courtesy of Emerson.

applications, like those used in the metals industry, which can help reduce energy consumption and decrease emissions.

Instead of firing continuously, the burners in pulse firing are frequently cycled between ON/OFF functions. By not firing all the time, pulse firing reduces

In addition to improving efficiency, higher turndown ratios also enable valves to handle a much wider range of pressures.

High close-off pressure ratings are also essential for burner applications subject to high system pressure spikes, which are often found in remote locations. Powerful motorised actuators enable some of the latest safety shut-off valves to handle gas pressures as high as 1.4 bar (20 psi) and close safely against higher pressure from 3 bar (30 psi) up to 5.2 bar (75 psi).

This helps provide reliable operation no matter where burners are located.

Industrial furnaces and gas-burning appliances can be found in nearly every climate. They may be located indoors, where they provide heat, or they may be outside, where they’re exposed to sweltering or freezing temperatures. But no matter what the thermometer says, it’s critical that safety shut-off valves operate reliably, even in punishing environmental conditions.

A new generation of safety shut-off valves offer reliable performance in a broader temperature range, from extreme cold to high heat. The robustness of the motorised actuator design and material

composition of the latest motorised safety shut-off valves are rated to function from -40°C (-40°F) up to 66°C (150°F). This is a big change in countries with cold climates, including Canada or Russia, as the low-temperature limit for motorised valves has been about -10°C (14°F) or -20°C (-4°F).

For gas-burning appliances subject to dirt, precipitation, water or the dust and soot found in metal and glass processing, a weatherproof, NEMA-4 and IP65 rated enclosure is also available. This optional protection helps ensure safety shutoff valves perform as expected, even in extreme or harsh conditions.

The high configurability of the latest pneumatic piston valves makes it possible for these valves to reliably function in temperatures that range from -60°C (-76°F) to 80°C (176°F), as well as in hazardous environments. Bronze or stainless-steel body selection can meet a broad range of connections, including flanges while the air-operated actuator can be plastic

or stainless steel if greater corrosion resistance is required. There’s also a broad range of signaling box options. Some are air pilot integrated, some are approved for explosive atmospheres (ATEX) while some have visual indication or proportional control.

Global compliance and simplified procurement Although a furnace may be manufactured in one area of the world, lots of manufacturers source components from and supply their products to regions far from where they’re located. As such, it’s critical that global manufacturers and their component suppliers know applicable regional and international regulations and standards.

Most, if not all, of these standards are intended to protect people and the environment and are often in accordance with detailed safety, construction or performance criteria. To meet exacting criteria, ensure reliable performance and

achieve compliance, safety shut-off valves must undergo highly rigorous testing to last hundreds of thousands of cycles.

To simplify compliant furnace designs across all regions, there are global certifications and approvals to look for in safety shut-off valves. These include UL, FM, CSA and EN 161 Class A, as well as RoHS directives.

Comprehensive pneumatic angle seat valves include European use with EN norms, including EN 161, EN 16678 and EN 13611, and have ATEX certifications.

These additional standards approve use in gas-burning applications, including those with complex fuel needs where typical solenoid valves fail.

Greater safety and energy efficiency: When using industrial furnaces in heattreating processes, the primary way to protect people and the environment is to start with reliable components that help save energy. It’s critical to know which features and capabilities to look for in safety shut-off valve technologies depending on its operating location, including the climate, conditions and regulations. Fuel trains equipped with compliant, long-lasting valves that consume less fuel mean a safer, cleaner combustion system for manufacturers and end users alike. �

FEVE: Furnace of the Future glass decarbonisation project The ‘Furnace for the Future’ (F4F) project held a webinar focused on the Furnace of the Future sustainability project as well as the decarbonisation steps the glass industry needs to take.

FEVE’s Future Made Clear webinar, which included Ardagh Glass CEO Martin Petersson and FEVE technical expert Fabrice Rivet as well as host, Feve Secretary General, Adeline Farrelly introduced and discussed the Furnace for the Future project to its audience.

For the very first time, 20 industry companies have joined forces to create, fund and test a pilot furnace project under real-life conditions to see if it can fully meet both technical and market criteria.

Ardagh Group has volunteered to build the furnace in Germany.

Mr Petersson described the Furnace for the Future project as a true industry collaboration, with Ardagh working alongside with 19 other glass manufacturers which represents 90% of total glass container production in Europe.

“Together our collective technical expertise and skills will be used to bring this sector level transition to the low carbon economy and we will share the know how to produce climate neutral packaging.

Our priority is to work on the melting technologies we currently use. We are looking to invert the fuel balance from today’s 80% gas and 20% electricity, to 20% gas and 80% renewable electricity with CO2 savings of 50% plus.

We believe we can use this technology to produce all glass colours with high levels of recyclable content.”

He added it will be the first time that all the elements of electric melting will be put together on this scale of industrial production.If an application for funding is successful the furnace will be built in 2022 and first glass produced in 2023.

For the first time, European container glass manufacturers have come together to build the world’s first large-scale

hybrid electric furnace to run on 80% green electricity. The industry’s collective ‘Furnace of the Future’ pilot project is a breakthrough technology, which claims it will enable the switch to green energy. � Capable of processing over 300 tonnes of glass per day � Replacing fossil fuel energy sources via a hybrid furnace using up to 80% green electricity � Able to melt all kinds of glass together with recycled glass

This pioneering hybrid technology overcomes a major milestone towards climate-neutral glass packaging. Today, by using more recycled glass, dramatic reductions in CO2 can be possible. This will replace current fossil-fuel energy sources and cut CO2 emissions by 50%.

Mr Peterson added, “We recognised from the start of this project that this is key to setting us on the path to climate neutral glass packaging and to ensure the long term sustainability of glass packaging.

By demonstrating the viability of electric melting on a commercial scale we will secure a sustainable future for glass as a sustainable material. This is vital for our industry, our company and our customers’ sustainability agendas.”

Fabrice Rivet’ FEVE’s Technical Director then outlined some of the challenges facing the project. The furnace will be deemed a hybrid furnace because, while most of it will be supplied by renewable electricity, a small amount of natural gas will be required.

While electric furnaces already exist, they are mostly used on a small scale of about 100 tonnes per day capacity and used by niche sectors such as perfumery.

“The main challenge for the Furnace for the Future is that we want to go big, we want to get to 350 tonnes per day capacity.”

Due to its larger size, the new furnace will be a horizontal rather than a vertical furnace and will therefore require different technology.

Another requirement is to produce all colours of glass, particularly amber glass.

Amber, or brown glass, is effective at protecting the contents of the bottle or jar from the sun’s UV radiation.

However it is a challenge to make brown glass using electricity due to the risk of foaming.

“So we have to heat where we need to have heat and which is why we will still have 20% natural gas to avoid this foaming.”

The final challenge was to ensure that the correct know how was disseminated across the industry once the new furnace is built.

“Such a furnace has never been built so far, this is the first of its kind, so we need to develop the right know how on how to operate this furnace. We need to operate it to get a glass, which meets customer requirements.

This know how is important, it is a reason for this sectoral approach in order for us to disseminate this know how across our industry.”

Out of more than 300 applications for funding from the EU, the Furnace for the Future project was one of only 70, which had made it through to the final stage of application.

Just 10 of these will be awarded funding and a final decision on successful applications is due at the beginning of November. �
