Fluidized Bed Combustion FBC Boiler - boilersinfo.c

(FBC) Fluidized bed combustion is a combustion technology used to burn solid fuels in steam boilers. In Fluidized Bed Combustion Boiler technology When air or gas is passed through an inert bed of solid particles such as sand supported on a fine mesh or grid, the air initially will seek a path of least resistance and pass upward through the sand.
