Circulating fluidized bed(CFB) boiler working principle

2019-3-21 · 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 combustion takes place in this suspended condition. This is the Fluidized bed.
