A combustor of an embodiment includes: a cylindrical combustor liner; and a fuel nozzle which is provided at one end of the combustor liner and jets a fuel and an oxidant into the combustor liner. The fuel nozzle includes: a plurality of fuel supply passages which each supply the fuel; and a plurality of oxidant supply passages which each supply the oxidant. Flow rates of the fuel supplied to the respective fuel supply passages and flow rates of the oxidant supplied to the respective oxidant supply passages are each individually regulated.

Gas turbine combustor

A combustor according to an embodiment includes: a cylinder body that demarcates a space between a combustor casing and a combustor liner; a pipe that guides a combustion gas between the combustor liner and the cylinder body; a pipe that guides a combustion gas having a temperature lower than a combustion gas to be guided to the pipe between the combustor casing and the cylinder body; a pipe-shaped member provided so as to penetrate the combustor casing, the cylinder body, and the combustor liner; a heat-resistant glass that is provided in the pipe-shaped member; a condensing lens provided in a manner to face the heat-resistant glass; and a laser oscillator that emits laser light to the inside of the combustor liner through the condensing lens.

Gas turbine combustor including laser ignition

A gas turbine facility of an embodiment includes: a combustor casing; a combustor provided in the combustor casing; a cylinder surrounding a periphery of the combustor and dividing a space between the combustor casing and the combustor; a turbine rotated by combustion gas exhausted from the combustor; a heat exchanger cooling the combustion gas exhausted from the turbine; a pipe through which a part of the combustion gas cooled in the heat exchanger passes in the heat exchanger to be heated, the pipe guiding the combustion gas heated in the heat exchanger into the cylinder; and a pipe guiding another part of the combustion gas cooled in the heat exchanger to a space between the combustor casing and the cylinder.

Gas turbine facility exhaust gas supply heat exchange arrangement

A gas turbine facilityin an embodiment includes: a combustor; a fuel nozzle; a turbine; a heat exchangercooling the combustion gas. The gas turbine facilityincludes: a pipeguiding a part of the cooled combustion gas to an oxidant supply pipe; a pipepassing a mixed gas composed of the oxidant and the combustion gas through the heat exchangerto heat it, and guising it to the fuel nozzle; a pipepassing another part of the cooled combustion gas through the heat exchangerto heat it, and guiding it to the combustor; a pipepassing still another part of the cooled combustion gas through the heat exchangerto heat it, and guiding it to the fuel nozzle; and a pipeexhausting a remaining part of the cooled combustion gas.
