Abstract
A power plant with combustion of a fuel at a pressure exceeding the atmospheric pressure in a fluidized bed (14) in a bed vessel (12) which is enclosed within a pressure vessel (11). The space (37) between the pressure vessel (11) and the bed vessel (12) is supplied with combustion air from a compressor (22). Ash and consumed bed material are taken out from the bed vessel (12) via an ash chamber (34) and are cooled therein by air from the space (37). The air from the space (37) is cooled in a cooler (44) before being supplied to the ash chamber (34).
