Technology Overview: Circulating Fluidized-Bed
A circulating bed boiler should not exceed a conventional atmospheric fluidized-bed combustor in capital coat, and will probably be less, due to reduced combustor size. The cost advantage of a pressurized circulating bed boiler is questionable. 2.

COAL CFB Boiler - Getabecboiler
Circulating Fluidized Bed (CFB Series) Combustion technology utilizes the fluidized bed principle in which crushed fuel is injected into the furnace or combustor and the fine combusted particles are elutriated out of the furnace with flue gas. The balance particles are then collected by solid separators and circulated back into the furnace.
