PURPOSE:To make it possible to change the ratio between the production amount of steam and the power generation amount by providing a regenerator for preheating combustion air with the use of exhaust gas from a gas turbine, by providing a bypass section therein, and by enabling a part of steam from a waste heat boiler to be fed into a part of the regenerator. CONSTITUTION:A regenerator 5 having a heat-exchanger part 6 and a bypass part 7 is disposed in pipe line 4 for air which is compressed by a compressor 1 direct-coupled to a turbine 3. A damper 8 disposed in the bypass part 7 in the regenerator 5 on the inlet side, is opened and closed through a worm 14 and a worm gear 13 in association with the operation of a motor 15. Exhaust gas discharged from the turbine 3 is led into a heat-exchanger 9 in the heat exchange part 6 so that compressed air fed from the compressor 1 is preheated, and thus preheated compressed air is fed into a burner 17 through a pipe line 16. Further, there is provided a waste heat boiler 22 for generating steam with the use of the heat of the exhaust gas discharged from the heat-exchanger 9, and extra steam from the boiler 22 is fed into a front stage chamber 10 in the regenerator 5.
