摘要： Extremely cold (e.g., −20° C.) air A is heated by a heat exchanger 30, which is supplied with steam S via a control valve 32, and heated air A′ is taken into a gas turbine 10. The valve opening degree of the control valve 32 is feedback-controlled so that the deviation between the measured temperature t1 and the target temperature TO of the heated air A′ is eliminated. Further, when the number of revolutions, N, of the gas turbine 10 increases, or when an IGV opening degree OP increases, the valve opening degree of the control valve 32 is feedforward-controlled in accordance with the increase in the number N of revolutions or the increase in the IGV opening degree OP. By so doing, the temperature of air A′ can be maintained at a temperature enabling stable combustion without delay in control, and intake air can be heated without delay in control, even at the start of the gas turbine or during change in the opening degree of an inlet guide vane.
