Gas Turbine Combustor

A gas turbine combustor including a plurality of fuel nozzles that inject fuel, an air hole plate including a plurality of air holes formed to correspond to the plurality of fuel nozzles, the air hole plate being provided on a downstream side in a flowing direction of the fuel of the plurality of fuel nozzles, and a combustion chamber that causes the fuel and an air injected from the plurality of air holes to burn to generate combustion gas,

• the air hole plate including a center air hole group configured from the plurality of air holes and a plurality of outer circumferential air hole groups configured from the plurality of air holes and formed to surround the center air hole group,
• the gas turbine combustor comprising:
• a hole part and a temperature sensor provided on the air hole plate to be located in a region surrounded by a pair of the outer circumferential air hole groups adjacent to each other and the center air hole group;
• a supply source of coolant;
• a cooling pipeline that connects the hole part and the supply source;
• a valve provided in the cooling pipeline;
• and
• a control system that drives the valve on the basis of a measured value of the temperature sensor.
