    Fluidized Bed Boiler - an overview | ScienceDirect Topics

    Solid material sent into the CFB boiler is mainly fuel and desulfurizer (with added bed material for some furnaces). The combustible elements of C, H, O, N, and S and all moisture transform into gas. The remaining solid material (mainly ash and some unburned carbon) should be discharged through proper equipment and at a corresponding position to maintain the material balance in the furnace.
