Circulating Fluidized Bed Combustion - an overview
In circulating fluidized bed combustion (CFBC) (Fig. 5), the gas velocity is higher than in FBC, and a large part of the solid particles is carried over from the bed into a tall riser, where the particles aggregate into clusters that reflux at the wall. Particles that are carried over from the riser are precipitated by a high-temperature process cyclone and are recirculated into the riser.
