  • 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.Get Price

  • CFBC Boiler vs Pulverized Fired Boiler
