Difference Between AFBC And CFBC Boilers--ZBG

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. a. High efficiency.

A Survey on Circulating Fluidized Bed Combustion Boilers

The main advantages of the fluidized bed combustion boilers are: reduced NOx, SOx due to relatively low combustion temperature, better efficiency and reduction in boiler size and design. It has the ability to burn low grade coal and it is less corrosive as the combustion temperature is less when compared to that of an utility boiler.
