ABSTRACT:
A method of controlling fuel of a gas turbine provided with a two-stage combustion type combustor wherein the fuel of gas is fed to the combustor only through a primary fuel nozzle under a low-run of the gas turbine and through the both the primary fuel nozzle and a secondary fuel nozzle under a high-run of the gas turbine, and controlled by a fuel control valve according to a load signal, comprises measuring the flow rate of the fuel passing through the fuel control valve; controlling the fuel control valve according to the measured flow rate so that the flow rate will be constant or a scheduled value when the gas turbine reaches to a predetermined load; and switching fuel supply to the combustor from the primary fuel nozzle to through both the primary and secondary fuel nozzles while the fuel control valve is controlled according to the measured flow rate signal.
