PCT No. PCT/SE90/00446 Sec. 371 Date Dec. 23, 1991 Sec. 102(e) Date Dec. 23, 1991 PCT Filed Jun. 20, 1990 PCT Pub. No. WO91/00474 PCT Pub. Date Jan. 10, 1991.The invention relates to a power plant with a combustor (10) with combustion of a fuel in a fluidized bed of a particulate material and with a storage container (36) for hot bed material for adjusting the bed height upon changes of the load by the transfer of bed material from the combustor (10) to the storage container (36) and vice versa. It is primarily intended for a PFBC power plant with the combustor (10) and the container (36) in a pressure vessel (14) filled with compressed combustion air. The container (36) is provided with an internal mantle (66) which surrounds the storage space (40) for the bed material and an internal insulation (68) in the gap (70) which is formed between the container wall (36a) and the mantle (66). The lower part of the mantle (66) is joined to the container wall by means of an outwardly and upwardly directed skirt-like flange (66a-c). |
