        Technology Overview: Circulating Fluidized-Bed Combustion

        In the circulating bed mode of fluidization, the entire reactor contains solids of significantly lower density than in conventional fluidized-beds. In addition, the degree of gas-solids contact over the entire reactor height leads to longer contact times in the CFB, even at the high gas velocities employed.

        Fluidized bed combustion - Wikipedia

        Fluidized bed combustion is a combustion technology used to burn solid fuels. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials through which jets of air are blown to provide the oxygen required for combustion or gasification. The resultant fast and intimate mixing of gas and solids promotes rapid heat transfer and chemical reactions within …
