  • Fluidized bed combustion Wikipedia

    OverviewBenefitsTypesSee alsoReferences (Requires update in links)

    Fluidized bed combustion (FBC) 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 (sand, limestone etc.) 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 the bed. FBC plants are capable of burning a variety o

  • What happens when limestone is fed in a coal-fired boiler

    It depends on the type of coal-fired boiler. If it’s a Bubbling Fluidised Bed (BFB) or Circulating Fluidised Bed (CFB) boiler then limestone could be added to the bed material to give a de-sulphurising effect. If it’s a Pulverised Fuel (PF) boiler.

  • Coal-Fired Boiler an overview ScienceDirect Topics
