Both agglomeration of bed material and corrosion of heat transfer equipment are issues related to combustion of biomass in a fluidized bed boiler. The biomass-ash component potassium is considered a major contributor for both phenomena. In this study, the conventionally used bed material, silica sand, was replaced with up to 40 wt % by the natural ore ilmenite in Chalmers 12 MWth circulating

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.

Summary of Biomass Combustion Technologies | BioEnergy Consult

9/4/2021 · The most common type of biomass boiler is based on a grate to support a bed of fuel and to mix a controlled amount of combustion air, which often enters from beneath the grate. Biomass fuel is added at one end of the grate and is burned in a fuel bed which moves progressively down the grate, either via gravity or with mechanical assistance, to an ash removal system at the other end.
