Circulating fluidized bed coal fired boiler,CFB coal fired

Suitable the fuel: Lean coal, bituminous coal, anthracite coal, lignite,coal gangue, etc. Combustion efficiency: higher than 97. The Circulating fluidized bed coal fired boiler contains mainly particles of an inert material, like sand and ash, including particles of SO2 sorbent. The coal content in a fluidized bed is not considerable, it is only from 3 to 5% of the whole mass of the bed.

Circulating fluidized bed coal fired boiler,CFB coal fired

CFB boilers are touted for their fuel flexibility. For instance, CFB coal fired boiler can efficiently use fuels such as low rank lignites and sub bituminous coals that typically produce a lot of ash and are difficult to use in other types of pulverized coal boilers. CFB boilers are even being used to remove gob piles in some areas.
