High Combustion Efficiency Industrial CFB Circulating

A circulating fluidized bed (CFB) boiler features higher gas velocity (superficial flow velocity) in the furnace (combustor) compared with a bubbling fluidized bed (BFB) boiler. The boiler activates a mixture of particles and gas to improve combustion reaction. Moreover, the fluid sand and fuel issuing out of the furnace are collected in a cyclone and recirculated into the furnace again, thereby improving combustion …

Circulating Fluidized-Bed Boilers - Babcock & Wilcox

Westinghouse has estimated that pressure losses for atmospheric pressure circulating-bed boiler systems would be about 2.7 in. W.C. per foot of bed height and that overall pressure loss including combustor, air preheater, particulate control, convection heat transfer, ducting, etc., would range from 50 to 80 in. W.C. ECONOMICS The costs of circulating fluidized-bed combustion systems are not well …
