Circulating Fluidized Bed Combustion

In fluidized bed combustion (FBC) (Fig. 4), crushed coal, 5–10 mm in particle size, is burned in a 1000-mm-deep bed of 0.5- to 3.0-mm particles consisting mainly of additive sorbents (limestone or dolomite) and coal ash. The bed is fluidized by a blast of air through a distributor plate at the bottom of the bed.
