Difference Between AFBC And CFBC Boilers--Z

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. The CFBC boiler has more advantages than AFBC boiler.
