Fluidized Bed Combustion | Fluidized Bed Boiler |FBC

The heat released during combustion heats up the surrounding boiler tubes and generates steam. The major advantages of Bubbling Fluidized Bed Combustion are the enhanced thermal efficiency, easy ash removal. Another type is the Circulating Fluidized Bed Combustion; it is applied to fuels with higher heating values such as Petcoke.

Текст 13. Fluidized bed boilers

Main types: there are two main types of fluidized bed combustion boilers: Bubbling fluidized bed (BFB) and Circulating fluidized bed (CFB) boilers. In the bubbling type, because the velocity of the air is low, the medium par- ticles are not carried above the bed. The combustion of this type of boiler is gener- ated in the bed.
