  • What is the meaning of CFBC boiler? | AnswersDrive

    AFBC is atmospheric fluidised bed combustion, where the furnace pressure is atmospheric pressure. In case of CFBC, Circulating fluidised bed combustion, the furnace is pressurised and the furnace gas is recirculated to capture the unburnt carbon, to increase the thermal efficiency of the boiler.
