ABSTRACT:
In a gas turbine combustor of the present invention, a pilot fuel nozzle is composed of at least two systems with different hole diameters, and the fuel flow rate of each system can be controlled independently. Also, even if the operation of main burners is switched in accordance with high or low load, the pilot fuel is selected accordingly. Further, the pilot fuel differential pressure is kept high to effect stable supply of fuel, and stable combustion is maintained.
