Pressurized Fluidized Bed Combustion (PFBC) Boiler

In type Pressurized Fluidized Bed Combustion (PFBC) boiler, a compressor supplying air Force Draft (FD) and the combustor is pressurized tank. The rate of heat release in the bed is proportional to the pressure in the bed so the bed is used for extracting large amounts of heat.

This condition will improve the combustion efficiency and sulfur dioxide absorption in the bed. Steam generated in the two tube bundles, one in the bed and one above it. Hot gas from flue gas drive gas turbine power generator.

System Pressurized Fluidized Bed Combustion (PFBC) Boiler can be used for cogeneration (steam and electricity) or power plant with combined cycle. Operating combined cycle (gas turbine & steam turbine) increase overall conversion efficiency 5% up to 8%.
