Title:
GAS TURBINE COMBUSTOR, GAS TURBINE, CONTROL DEVICE, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2015/166597
Kind Code:
A1
Abstract:
Provided is a gas turbine combustor and the like capable of maintaining flame-holding performance through suppressing the amount of generated NOx while suppressing burning of the area around a pilot nozzle including the pilot nozzle itself. The gas turbine combustor (12) is equipped with: a pilot nozzle (59) capable of injecting fuel (F) and cooling air (A) for cooling the nozzle tip; a flow rate regulation valve (77) capable of regulating the flow rate of the cooling air supplied to the pilot nozzle (59); a detection sensor (92) for detecting a combustion state of the fuel; and a control device (91) for controlling the flow rate regulation valve (77) on the basis of a detection result of the detection sensor (92).
