Fluidized Bed Combustion (FBC Boiler) “Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels.”. A bed of solid particles is said to be fluidized when the pressurized fluid (liquid or gas) is passed through the medium and causes the solid particles to behave like a fluid under certain conditions.. Fluidization causes the transformation of the state of solid particles from …

lexie@zozen.com > Get A Quote >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. With further increase in the velocity, the air bubbles through the bed and the particles attain a state of high turbulence. Under such conditions, the bed assumes the …
