The circulating fluidized bed is a type of Fluidized bed combustion that utilizes a recirculating loop for even greater efficiency of combustion. while achieving lower emission of pollutants. Reports suggest that up to 95% of pollutants can be absorbed before being emitted into the atmosphere. The technology is limited in scale however, due to its extensive use of limestone, and the fact that it produces waste …

Cfb boiler basic design, operation and maintenance

Summary: Circulating Fluidized Bed boilers have witnessed substantial growth over the past couple of years owing to the increased need for power coupled with stricter emission norms which resulted in the need for cleaner methods of power generation. CFB boilers, due to their lower operating temperatures reduce the emission of gases such as sulfur dioxide, carbon dioxide and nitrogen dioxide.

CFB Boiler - Coal Fired Boiler, Biomass Boiler, Pressure

Circulating Fluidized Bed (CFB) Boilers. 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 …
