Combustion In Circulating Fluidized Bed Boilers

Circulating fluidized bed(CFB) boiler working principle ...

Circulating fluidized bed technology (CFB) also offers the flexibility of using both coal as well as biomass fuels. Air supply is from under the bed at high pressure. This lifts the bed material and the coal particles and keeps it in suspension. The coal takes place in this suspended condition. This is the .
