Mitsubishi Power, Ltd. | Circulating Fluidized Bed (CFB

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 …

Progress of circulating fluidized bed combustion

The first lower energy consumption CFB boiler based on the re-specification of the fluidization state began commercial operational in 2007. As shown in Fig. 5, the field test results [] showed that with the pressure drop decrease from 7.3 to 3.2 kPa, the solid suspension density in the dilute zone was barely influenced due to the higher collection efficiency of the cyclones.
