PFBC power plant for burning fuel, primarily coal, in a fluidized bed of particulate material, at a pressure exceeding the atmospheric pressure. The plant comprises a bed vessel (12) which is divided into a first section (14) and a second section (16) by a vertical partition (17) which reaches up to the upper wall of the bed vessel (12) so as to form two separate freeboards (86 and 46, respectively), one for each section of the bed vessel. The first section (14) of the bed vessel (12) forms a gas generator in which a burnable gas is generated. This burnable gas is cleaned in a gas cleaner (90), then burnt in a secondary combustion chamber (98), and then mixed with the combustion gases from the second section (16) of the bed vessel (12), thus raising the temperature of the gas supplied to a gas turbine to an optimum level for the gas turbine. |
