Circulating Fluidised Bed Combustion (CFBC) Boilers

The boiler is designed with fluidising velocities up to 4.5m/s, generating a high turbulence and resulting in a good mixing of hot bed material with fuel and recirculated fly ash. The height of the bed is kept constant by removal of the produced bed ash as a function of the differential pressure between the

CFBC boiler process and their advantage over AFBC boiler

Sep 01, 2017· ADVANTAGE OF CFBC BOILER OVER AFBC BOILER:- 1.We get the higher temperature from CFBC boiler because of high gas velocity through the system. 2.Lower combustion temperature can be achieving constantly, which result in minimum NOx formation. 3.In CFBC boiler the combustion air is supplied at lower pressure as compared to the AFBC boiler .
