METHOD FOR OPERATING A GAS TURBINE PLANT WITH GASEOUS FUEL

The invention relates to a method for operating a gas turbine plant with gaseous fuel, which is conveyed to the gas turbine plant through a gas line (6), burnt in a combustion chamber (4) and then supplied to a gas turbine. At least one valve (12a, 12b) for controlling the flow of the fuel to the combustion chamber (4) is installed in the gas line (6), a critical opening position (Skrit) being defined for the valve (12a, 12b). According to the invention, to provide an improved method for operating a gas turbine plant in which the power (P) of the gas turbine plant is kept at a maximum for as long as possible in the event of insufficient pressure in the gas line (6), a temperature (TB) of the fuel in the gas line (6) is reduced when the valve (12a, 12b) is about to exceed the critical opening position (Skrit). 一种用于运行具有气态燃料的燃气轮机设施的方法，所述气态燃料通过气体管路(6)被运输到所述燃气轮机设施、在燃烧室(4)中燃烧并且紧接着被输送给燃气轮机。在所述气体管路(6)中装入有至少一个阀门(12a，12b)，用于进行至燃烧室(4)的燃料的流量调节，其中对于所述阀门(12a，12b)定义临界打开位置(Skrit)。关于用于运行燃气轮机设施的改进方法，其中在气体管路(6)中的压力不足的情况下燃气轮机设施的
