    • 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.
    • 一种控制具有两级燃烧式燃烧器的燃气轮机的燃料的方法,其中气体燃料仅通过燃气轮机低压下的主要燃料喷嘴进入燃烧器,并通过两种主燃料 喷嘴和在燃气轮机的高运行下的次级燃料喷嘴,并且根据负载信号由燃料控制阀控制,包括测量通过燃料控制阀的燃料的流量; 根据测量的流量控制燃料控制阀,使得当燃气轮机达到预定负载时,流量将恒定或预定值; 以及在燃料控制阀根据所测量的流量信号进行控制的同时,将主燃料喷嘴的燃料供给切换到主燃料喷嘴和辅助燃料喷嘴两者。
