Abstract

A flame produced within a premixer is promptly extinguished and a reduction in output power of a gas turbine associated with extinguishment is suppressed. In a gas turbine combustor 2 including a diffusion burner 41 and a premixed burner 42, the premixed burner 42 is configured with a burner liner 42b that surrounds the diffusion burner 41; a burner casing 42c that surrounds the burner liner 42b; a plurality of vanes 42d that separate a cylindrical space between the burner liner 42b and the burner casing 42c into a plurality of premixers arranged side by side in a circumferential direction; a plurality of premixed fuel nozzles 42a that inject a premixed fuel to the premixers; at least one thermometer 42e installed to be buried in one of the vanes 42d, and the like, and in a case in which a detection value of the thermometer 42e exceeds a corresponding set value, an opening of each of premixed gas control valves is reduced and an opening of a diffusion gas control valve is increased in such a manner that a sum of flow rates of fuels supplied to the diffusion burner 41 and the premixed burner 42 remains unchanged.
