Zusammenfassung:	PROBLEM TO BE SOLVED: To dispense with a temperature sensor exclusive for temperature detection within a combustor by using the heating coil of a glow plug as thermosensitive resistance element, and calculating the temperature within the combustor by the use of a table, in which the characteristic of temperature to the resistance value of the glow plug is set. SOLUTION: A constant current is carried to a glow plug 5 via a constant current drive part 2 controlled by an ECU 1 to preheat a combustor 6. Fuel is supplied from a fuel feed part 3 to the combustor 6 in a prescribed flow rate, and the fuel is combusted under the supply of compressed air from a compressor 7 to generate a high-pressure combustion gas, which is then supplied to a turbine 8. At this time, the glow plug 5 is driven with constant current, whereby the resistance value of the glow plug 5 is measured by a resistance measurement part 4, and the internal temperature of the combustor at that time is calculated by use of a table, in which the temperature characteristic to the resistance value of the glow plug 5 is set with the air flow rate as parameter.
