Fluidized bed combustion - Wikipedia

Fluidized Bed Combustion. Atmospheric fluidized beds use limestone or dolomite to capture sulfur released by the combustion of coal. Jets of air suspend the mixture of sorbent and burning coal during combustion, converting the mixture into a suspension of red-hot particles that flow like a fluid. These boilers operate at atmospheric pressure.

Fluidized bed boilers contain noncombustible solids in combustors. The Ca and K of biomass could react with quartz in these solids coating them with low softening temperature Ca or K silicate layers that cause agglomerates. In fluidized beds separate molten ash particles are formed with type 2 ash that is rich in silica and cause agglomeration.
