Circulating fluidized bed coal fired boiler,CFB coal fired

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. CFB boilers are touted for their fuel flexibility.

Experimental Investigations on Deposit Formation by

In coal fired CFB boilers, limestone can be continuously injected into the combustion chamber to capture the sulphur dioxide formed from sulphur components of the coal. In typical air-fired CFBs with operating temperatures of around 800-850°C, the inserted limestone is first calcined (Eq. 1) and then sulphated to CaSO 4 (Eq. 2)[7]. CaCO 3 CaO
