PROBLEM TO BE SOLVED: To provide a gasifying combined power generation equipment whereby kept energy of extraction air supplied to a low pressure type air separator can be effectively applied without reducing residual oxygen concentration of exhaust gas supplied to a boiler equipment, in the case of providing the boiler equipment with high temperature exhaust gas of a gas turbine serving as an oxidizing agent. SOLUTION: In this gasifying combined power generation equipment provided with a gasifying equipment 1, gas turbine equipment 6, and a boiler equipment 10 to burn fuel in the boiler equipment 10 with exhaust gas in the gas turbine equipment 6 serving as an oxidizing agent, a low pressure type air separator 7 liquefying pressure air separated in low pressure oxygen gas and nitrogen gas and an oxygen gas compressor 16 (for instance, turbine compressor) further pressurizing oxygen gas separated by high pressure extraction air from the gas turbine equipment 6 are provided. The high pressure extraction air, after its temperature is increased to a high value (for instance, about 500 to 600 deg.C), is supplied to the oxygen gas compressor 16, and oxygen gas is further pressurized therein, to be supplied to the gasifying equipment 1.
