口温度推定回路。In a gas turbine, a circuit detects a combustor inlet air flow rate and a combustion flow rate, transmits both to a divider through a signal gate, and calculates a fuel-air ratio between the fuel flow rate and the air flow rate, and the output of this circuit. A circuit that calculates the increase in gas temperature by multiplying the signal by a coefficient determined by the air, fuel characteristics, and combustor characteristics, and an adder that adds the output signal of this circuit and the combustor inlet air temperature. A circuit that compensates for the response delay between the combustor inlet and outlet in the combustor output, and a signal gate for the circuit that detects the gas generator rotational speed and calculates the fuel-air ratio when the rotational speed is higher than the idling rotational speed. A turbine inlet temperature estimation circuit for a gas turbine, comprising a signal gate control circuit that opens to operate the circuit and closes a signal gate of the circuit for calculating the fuel-air ratio when the number of revolutions is below idling.
