10-09-2015. The increasing demand for circulating fluidized bed (CFB) boilers to co-fire biomass and waste fuel products creates increased stress on refractory systems resulting in more frequent replacement cycles and increased maintenance costs.The problems with refractory systems in this application are accentuated due to improper application or inappropriate material selection.
Fluidized-bed boilers are the most common type of boilers recommended for biomass fuel. The fuel is suspended by an upward flow of combustion air through a bed of hot, inert particles, allowing oxygen to reach the combustible material more readily.
In biomass fired FBC boilers, partial melting is considered as the main mechanism leading to bed agglomeration . Fig. 10 shows the development of an ash layer rich in potassium after few hours of operation in a fluidized bed boiler which ultimately results in the formation of agglomerates.

Mar 31, 2010· A typical bubbling fluidized bed boiler has rows of “tuyeres” that line the distributor plate (furnace floor). High levels of primary or underfire air (as much as 70%) are used to push the bed
David A. Tillman, in Coal-Fired Electricity and Emissions Control, 2018. 2.1.3 Control of NO x. Fluidized bed boilers of all types are, by virtue of their combustion temperatures, low NO x generators. Operating the reactors at temperatures ≤1700°F virtually eliminates formation of any thermal NO x.All NO x is generated from the conversion of fuel nitrogen.
Valmet’s boiler solution utilizing bubbling fluidized bed (BFB) combustion technology is called Valmet BFB Boiler (formerly HYBEX). Wide fuel flexibility, high combustion efficiency, high reliability, excellent controllability and low emissions have turned it into a real winner, with over 200 deliveries and boiler conversions around the world.
