摘要
The present invention relates to a coal gasification combined cycle power generation system and a coal gasification combined cycle power generation system that can prevent the decrease in summer output. In the coal gasification combined cycle power generation system capable of preventing a decrease in summer output according to the present invention, the oxygen separation device (9), coal gasification unit (1), air compressor (3), gas turbine combustor (2), gas turbine (4), in the coal gasification combined cycle system comprising a heat recovery boiler (6) and a steam turbine (8), the temperature for sensing the temperature of the outside air flowing into the gas turbine air compressor (3) When the temperature of the sensing means 10 and the outside air detected by the temperature sensing means 10 is above a predetermined temperature, the inflow of the outside air supplied to the gas turbine air compressor 3 is blocked. Between the opening and closing means 20 for bypassing the heat exchange means 30 of the oxygen separation device 9 and the oxygen separation device 7 described above with the outside air bypassed by the blocking of the opening and closing means 20. The gas turbine ball is cooled to a constant design temperature by heat exchange. Characterized in that it further comprises an outside air cooling means 100 composed of the heat exchange means (30) for introducing into the compressor (3).
