Abstract
A power plant burning a fuel, primarily coal, in a bed vessel with a fluidized bed of a particulate material at a pressure exceeding atmospheric pressure. Consumed bed material and/or ashes separated from combustion gases are removed through a pressure-reducing discharge means. A part of the pressure-reducing discharge means is located in a dryer for crushed coal which forms a bed arranged as a bed vessel where crushed coal to be dried forms a fluidizable bed. The bed is fluidized by gas introduced through nozzles in the bottom of the bed vessel. The discharge portion constitutes a heater for the bed and a cooler for the discharge portion.
