Difference Between AFBC And CFBC Boilers--ZBG

Kefid 17:37:12. AFBC means atmospheric fluidized bed combustion, where the furnace pressure is atmospheric pressure. CFBC boiler stands for circulating fluidized bed combustion boiler, the furnace is pressurised and the furnace gas is recirculated to capture the unburnt carbon, to increase the thermal efficiency of the boiler. Hence this is an improved version of AFBC.
