To provide a highly reliable gas turbine combustor for controlling a load change at the fuel switching of the gas turbine combustor, and for detecting the burner temperature rise of a combustor and protecting thereof.
A gas turbine combustor includes a first fuel supply system 121 for supplying a liquid fuel 100 to a liquid fuel nozzle 13, a first flow regulating valve 105 provided there, a second fuel supply system capable of supplying fuel to a combustion chamber, a second flow regulating valve provided there, and a thermometer 250 for measuring a temperature of a fluid that flows in a flow path from the downstream side rather than the first flow regulating valve to a mixing chamber 11a or a member constituting the flow path, wherein the combustor includes a regulator 260 for controlling at least either one of the opening of a first flow regulating valve or a second flow regulating valve by detecting a change of a temperature of the fluid or the member constituting the flow path measured by the thermometer when a liquid fuel feed to the first fuel supply system is started and an operating state is switched.
