Fluidized bed combustion - Wikipedia
Fluidized bed combustion boilers (FBC) is a combustion technology, based on a layer of sand or a sand-like media, where the fuel is introduced into and combusted. The combustion air blows through the sand layer from an opening in the bottom of the boiler. A bed of solid particles is said to be fluidized when the pressurized fluid (liquid or gas) is passed through the medium and …
