Fluidized bed combustion - Wikipedia

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-generation PFBC system also uses a sorbent and jets of air to suspend the mixture of sorbent and

Pressurized Fluidized Bed Combustion (PFBC) Boiler : In Pressurized Fluidized Bed Combustion (PFBC) type, a compressor supplies the Forced Draft (FD) air and the combustor is a pressure vessel. The heat release rate in the bed is proportional to the bed pressure and hence a deep bed is used to extract large amount of heat.
