Power plant for burning fuel, primarily coal, in a bed vessel (12) with a fluidized bed (22) of particulate material at a pressure exceeding atmospheric pressure. Consumed bed material and/or ash separated from the combustion gases are removed via a pressure-reducing discharge means (50). A part (50b) of this discharge means is located in a drier for crushed coal in the form of a bed (56). This is arranged as a bed vessel (54) where crushed coal to be dried forms a fluidizable bed (56). The bed (56) is fluidized by gas introduced through nozzles (66) in the bottom (64) of the bed vessel. The discharge part (50b) constitutes a heater for the bed (56) and a cooler for the material to be discharged by the discharge means (50). |
