PROBLEM TO BE SOLVED: To provide a gas turbine device which performing the control for maintaining the number of revolutions of a turbine at a fixed number and detecting the occurrence of flame-out quickly even when performing operation as load increases. SOLUTION: This gas turbine device is provided with an air-fuel ratio calculation part 31 for calculating an air-fuel ratio of air and fuel in air-fuel mixture, a compensation air-fuel ratio calculation part 34 for calculating a compensation air-fuel ratio which becomes substantially constant by adding a predetermined compensation value fluctuating in accordance with a value detected by a pressure detection part 20 to the air-fuel ratio calculated by the air-fuel ratio calculation part 31, and a flame-out discrimination part 33 for discriminating that flame-out occurs when the compensation air-fuel ratio calculated by the compensation air-fuel ratio calculation part 34 is lowered below a predetermined reference air-fuel ratio.
