PROBLEM TO BE SOLVED: To provide a coal gasification combined-cycle power generation plant which enables the installation cost to be reduced and can prevent the efficiency from being lowered.SOLUTION: This coal gasification combined-cycle power generation plant includes a gasification furnace 9 to which coal is led, a gas turbine 16 comprising a combustor 17 in which a fuel gas gasified in the gasification furnace 9 is burned, an exhaust heat recovery boiler 23 which generates steam by the exhaust gas discharged from the gas turbine 16, a steam turbine 25 to which the steam generated in the exhaust heat recovery boiler 23 is led, a generator 21 which is driven by the steam turbine 25 and the gas turbine 16 to generate power, and a carbon dioxide recovery device 13 to which a part of the exhaust gas led from the gas turbine 16 thereto for recovering the carbon dioxide. Coal is conveyed to the gasification furnace 9 by the carbon dioxide. |
