Refractory Ferrules Market - Global Industry Analysis, Size, Share, Growth, Trends and Forecast 2017 - 2025
Refractory ferrules are specially modified ceramic heat transfer agents that are embedded into metallic casings. They are utilized to transfer heat from high temperature boilers to other refineries and chemical units. Refractory ferrules installed in a boiler help minimize heat losses from the furnace and contain the heat generated in the furnace. Refractory ferrules must have insulating properties to withstand extremely high boiler temperatures. Refractory ferrules used inside the boiler furnace should be made of inert materials. They should not contaminate the materials with which they are in contact during the operation. Refractory ferrules are primarily used in the chemical industry for heat transfer at extremely high temperature. Ceramic ferrules possess superior heat transferring properties at extremely high temperatures; therefore, they are employed in sulfur recovery units in petrochemical reformer units. Ceramic ferrules are mostly made of zirconium, alumina, and mullite. Recent technological advancement in composite material development has made it possible to use composites in the manufacture of refractory ferrules. These ferrules protect carbon steel tubes and welded joints of the boiler from extreme heat and chemical corrosion & degradation. In order to withstand these constraints, refractory ferrules should have high mechanical strength, chemical resistance, and thermal shock resistance at elevated temperatures. Failure of refractory ferrules in boiler applications can result in unplanned shutdown of the entire production unit.

Designing of industrial refractory ferrules depends on operating parameters, unit construction, and historical performance of the boiler. Other important factors that should be taken into account before installation of ferrules are operating temperature range, unit environment, operating pressure range, tubing and pipeline design, tubing material, and cost. Commonly used refractory ferrules include regular ring ceramic ferrules, double ring style ferrules, tapered style ceramic ferrules, solid head ceramic ferrules, hexagon ceramic ferrules, and round refractory ferrules. Most commonly used refractory ferrules in boiler operations are round ferrules embedded in a monolithic refractory setting. It is used to protect boiler tubing from extremely high temperature and pressure. Hexagonal refractory ferrules also employed in majority of boiler applications that require special operating conditions. These are highly flexible in applications among different tubing and pipeline designs and are compatible with the systems that use oxygen enrichment in the boiler. Hexagonal refractory ferrules possess lower pressure drop compared to round ferrules. This helps improve process efficiency by preserving heat losses.
