2A2. Circulating Fluidized-bed Combustion Technology

circulating fluidized-bed boilers involves a two-stage combustion process: the reducing combustion at the fluidized-bed section, and the oxidizing combustion at the freeboard section. Next, the unburned carbon is collected by a high-temperature cyclone located at the boiler exit to recycle to the boiler, thus increasing the denitration efficiency.

Why to prefer Fluidized bed combustion boilers ?:- EnergyPurse

Dec 24, 2018 · The fluidized bed combustion (FBC) takes place at about 840°C to 950°C for coal. Since this temperature is much below the ash fusion temperature, melting of ash and associated problems are avoided. Main reasons for consideration of Fluidized bed combustion Boiler :-Liberty of fuel choice Normally fuel burns at 700 to 900 Deg C.

Fluidized Bed Combustion - an overview | ScienceDirect Topics

Fluidized Bed Combustion. Fluidized bed combustion (FBC) is a well-established commercial combustion technology, in which combustion occurs in the presence of high concentrations of solids, typically sand, ash or that derived from limestone, if in-situ sulphur capture is required (i.e., a bed), which are fluidized in a stream of combustion air.
