the type of fuel. The boiler provides customers in coal-rich markets with the opportunity to reduce operating costs and increase output. According to Pierre Gauville, Alstom’s CFB Product Manager, one of the advantages of this new technology is that the overall efficiency of a power plant is increased by around 3 points. It also reduces the CO2 footprint by 6% compared to traditional technology. “Our CFB boiler is a cost effective solution to burn fuel efficiently with a very low NOx as compared to the conventional boiler,” he added.

lstom designs and supplies utility-scale boilers burning a wide range of fossil fuels for steam power generation. With over 100 years of experience, Alstom continuously innovates in clean combustion technologies with its utility boilers. Up to 30% of the world’s boilers use Alstom technology, producing a staggering combined output of 835 GW. With an extensive range of boilers and firing systems, Alstom’s combustion technology has been proven to burn coals, lignites, biomass, liquid fossil fuels, and gaseous fossil fuels as cleanly
as possible. That means improved efficiency and reduced emissions of NOx, SO2 and greenhouse gases.

E has its eyes set on growth and expansion especially with energy demand in Asia expected to grow 3.7% for the next 20 years. “In the ASEAN region, growth demand is expected to double during the same period as well so I think all in all, from energy demand to energy growth, the market is very hot right now,” says Ramesh Singaram, Regional General Manager, Power Generation Products and Services, GE Power & Water. According to Christopher Mastriani, F-Class Gas Turbine Upgrades Product Manager, Power Generation Services, GE launched two new GE solutions platforms as part of its Predictivity portfolio. GE’s new solutions One of the solutions, the FlexEfficiency Advantage (FEA) platform, focuses on GE’s F-class gas turbines where advanced gas path hardware are combined with software to provide additional output, efficiency, reliability, and emissions reduction capability of that hardware,” says Mastriani. GE customers also can benefit from an extension of maintenance intervals, asset and parts life through more durable hardware components and software technology that automate operational adjustments to reduce stresses on parts. On the other hand, GE’s LifeMax Advantage solutions help GE customers with installed B/EClass gas turbines reset the clock on their aging assets with tailored upgrade packages. The installation of GE’s most advanced hard-
Advanced CFB boiler During the recently held POWERGEN Asia in Bangkok, Alstom launched the new Advanced Circulating Fluidised Bed boiler that utilises the efficiency of ultra-supercritical (USC) steam conditions and the flexibility of circulating fluidised beds (CFB). It offers 660 MW or more in output, based on
Efficiency and low emissions Alstom also revealed that circulating fluidised bed technology allows for a wide range of lower-grade fuels, such as lignite and anthracite, to be combusted efficiently and with low emissions – reducing the need for additional environmental protection measures. Further versatility comes from the ability to fire on mixes of fuel types, and even ‘fuels of opportunity’, including biomass and oil shale. Over 32 GW of CFB boilers installed in the world today use the Alstom technology with a maximum commercial size around 350 MW.. This product is best deployed in markets where lower quality fuel is available. As a result, areas of Vietnam near the anthracite mining industry is a prime market.

ware and software offerings on this fleet of units, which averages more than 17 years in operation, can significantly extend their life cycle of operation. GE’s LMA platform features solutions including upgrades to B/E-Class AGP systems; DLN combustion technologies such as 32K, which allows operators to run their units up to 32,000 hours between scheduled maintenance intervals;
and Flange-to-Flange replacements of core engine components.
