PURPOSE:To prevent generation of air pollution substances such as MOx, SOx, etc., by generating power through a CO reheat gas turbine in which carbon dioxide gas is produced by using oxygen gas as a combustion oxidizing agent to perform combustion of carbon monoxide gas and circulated as working fluid. CONSTITUTION:In a CO reheat gas turbine 1, in a combustor 4, combustion of carbon monoxide gas CO is performed by oxygen gas O2 to produce carbon dioxide gas CO2, and in a high pressure turbing 5, power is generated with the above described CO2 gas serving as working fluid, while in an intermediate pressure turbine 6, power is generated with the CO2 gas, discharged from the turbine 5, serving as working fluid. In an afterburner 7, the CO2 gas, discharged from the turbine 6, is mixed to burn the CO gas by O2 gas with the CO2 gas produced, and in a low pressure turbine 8, power is generated with the CO2 gas from the afterburner 7 serving as working fluid. That is, by using not air but O2 gas as a combustion oxidizing agent while CO in place of fossil fuel, respectively, generation of NOx and SOx is prevented. |
