      Fluidized Bed Combustion - an overview | ScienceDirect Topics

      Bruce G. Miller, in Clean Coal Engineering Technology, 2011. Fluidized-Bed Combustion. Fluidized-bed combustion is not an SO 2 control technology per se. However, this combustion technology does offer the capability to control SO 2 emissions during the combustion process rather than postcombustion where FGD systems need to be installed. Fluidized-bed combustion and the role of sorbents in

      Fluidized Bed Combustible. 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. Pressurized Fluidized Bed Combustion. The first …
