3.0 Fluidized bed coal plants In fluidized bed combustion (FBC), solid fuels are suspended on upward-blowing jets of air during the combustion process. The result is a turbulent mixing of gas and solids. The tumbling action, like a bubbling fluid, provides more effective chemical reactions & heat transfer [6].
