CFBC boilers are mostly claimed to be more cost effective than AFBC boilers for industrial uses requiring more than 80-110 T/hr of steam. CFBC needs huge mechanical cyclones to aquire and recycle the high amount of bed material, which need tall boiler. Fig. shows CFBC bed boiler.
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…

AFBC Boiler VS CFBC Boiler - Circulating fluidized bed boiler
Oct 28, 2016 · AFBC = 1.2 m/sec to 3.7 m/sec. CFBC = 3.7 m/sec to 9 m/sec. 2.Heat Transfer Surface: AFBC = Heat is extracted within the the bed. CFBC = Heat transfer occer outside of combustion zone i-e Convection section, water walls and at the exit of the riser. 3.
Dec 11, 2015 · Presentation on CFBC Boilers 1. Key benefits are fuel flexibility, reduced emission and lower bed temperature. 2. Different Versions Industrial boilers ore developing with gradual change in their design of different parts and to optimize the thermal efficiency, fuel multiplicity and to sustain with environmental norms, with cost effectiveness for installation operation and maintenance. In our
Unlike Bubbling AFBC boilers, erosion-prone submerged heating surfaces are dispensed with. The recirculated cold fly ash takes over the cooling of the fluidised bed. It is in the convection pass, that the heat taken is transferred to the convectional heating surfaces. The boiler has a tower-type arrangement. The first boiler pass is formed
Atmospheric Fluidised Bed Combustion Boiler ( AFBC ) – Enmas GB …. Atmospheric Fluidised Bed Combustion Boiler (AFBC) Capacities: Up to 200 TPH Twelve (12) nos AFBC boilers having capacities varying between 55 TPH to 170. Fluidized bed combustion – Wikipedia Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels.
