摘要： A fuel supply amount is controlled while the load of a gas turbine is changed so that the fuel supply amount is shifted to a fuel supply amount in accordance with the changed load. A fuel supply control valve is operated at high speed during an initial stage and operated at a lower speed as the fuel supply amount necessary for the changed load is reached. Therefore flameout of a combustor is prevented without increasing the number of revolutions of the gas turbine over a certain upper limit.
摘要翻译：在改变燃气轮机的负荷的同时控制燃料供给量，使得燃料供给量根据改变的负载转移到燃料供给量。燃料供给控制阀在初始阶段以高速运行，并且在达到改变的负荷所需的燃料供给量时以较低的速度运行。因此，在不增加燃气轮机的转数超过一定上限的情况下，能够防止燃烧器的熄火。

摘要： A combined gas turbine plant comprises an air compressor, a combustor including a combustion chamber, a gas turbine, a steam turbine, and an exhaust heat recovery device having a denitration device and arranged at a location through which an exhaust gas passage for leading exhaust gas from the gas turbine to the atmosphere extends. An air extraction pipe equipped with a valve is provided for extracting a part of the air from the air compressor to prevent surging of the air compressor during starting of the plant, and another air extraction pipe equipped with a valve is provided for extracting a part of the air from an air passage extending from the compressor to the combustion chamber to improve stability of a flame and combustibility in the combustion chamber during the plant starting. The extraction pipes extend to and hence lead the extracted air into a portion of the exhaust gas passage located downstream of the denitration device.
