FLUIDIZED BED COMBUSTION Fluidized bed combustion (FBC) is a combustion technology used in power plants. FBC plants are more flexible than conventional plants in that they can be fired on coal and biomass, among other fuels. Fluidized beds suspend solid fuels on upward-blowing jets of air during the combustion process.
