In AFBC, coal is crushed to a size of 1 – 10 mm depending on the rank of coal, type of fuel feed and fed into the combustion chamber. The atmospheric air, which acts as both the fluidization air and combustion air, is delivered at a pressure and flows through the bed after being preheated by the exhaust flue gases.

Cyclone boilers burn crushed (but not pulverized) coal in large (e.g., 10-ft dia.) cyclone barrels and send hot (e.g., 3200–3550F or 1760–1950C) gases into the furnace and then convective pass. Cyclone boilers are designed to maximize the production of slag from the inorganic constituents in fuel; inorganics are managed in this manner.
