Circulating Fluidized Bed (CFB) Boilers | Boilers

2020-1-31 · Boilers Circulating Fluidized Bed (CFB) Boilers. The flue gas temperature in the furnace sometimes reaches 1,400-1,500°C. In case of CFB, however, it is in the low range of 800-900°C, thus inhibiting the generation of thermal nitrogen oxides (NOx whose production is dependent on combustion temperature). Further, with the use of two-stage
