IOWA RESOURCES AND FLUIDIZED BED COMBUSTION

Pressurized fluidized bed combustion is based on known components working in a combined advanced clean-coal system: fluidized bed, gas turbine and steam turbine. Taking into consideration P200 combustor, the combustion of coal takes place in the bed vessel at about 850 °C under high pressure (12 bar). PFBC technology is a one-step process for converting coal directly into power, with a number of …
