PURPOSE:To remove CO2 with high efficiency and the min. energy loss by installing a reactor for converting CO in the purified gas to CO2 and a CO2 removing device for removing CO2, between a gas purifying device and a combustor of a gas turbine power generation device. CONSTITUTION:The generated gas which is generated in a coal gas furnace 1 and from which impurities are removed by a gas purifying device 2 is supplied to a combustor, together with the high pressure air supplied from an air compressor, and combusted, and the generated high pressure high temperature gas is supplied into a gas turbine 3, and work is executed to drive a power generator. The exhaust gas which is discharged from the gas turbine 3 is supplied into an exhaust heat recovering boiler 4, and steam is generated, and this steam is supplied into a steam turbine 5, and the power generator is driven. In such a compound power generation plant, a shift reactor 6 for converting CO gas to CO2 gas by introducing the turbine extracted steam into the generated gas and a CO2 removing device 7 for removing the CO2 are installed in succession at the outlet of the gas generator 2. |
