Gas turbine, the gas turbine control apparatus and gas turbine operating method

A gas turbine (10), equipped with a compressor (11), a combustion chamber (12) and a turbine (13) is also equipped with a pressure build-up device (40) to divert a portion of the compressed by a compressor compressed air (11) ; a combustor cooling line (49) for cooling the combustion chamber (12) using the compressed air pressure; a temperature-regulating line (48) for regulating the temperature of a stationary part of the ring blade (37) or the like of a turbine (13) using the pressurized compressed air; a combustor supply line (45) through which the pressurized air from the pressure build-up device (40) to the combustion chamber cooling pipe (49) flows; a turbine supply line (44) through which the pressurized air from the pressure build-up device (40) for temperature regulation line (48) flows; a heater (62) for heating the compressed air, which is provided on the turbine supply line (44); a control unit (50) that can control the heater (62).
