    • An operation control method for a gas turbine comprising the steps of: making a molten salt map in a liquid phase state by calculating a dew point and a solidus temperature of molten salt for causing high-temperature corrosion on high-temperature components of the turbine due to impurities using a thermodynamic equilibrium calculation on the basis of the impurities contained in low-quality fuel and operation data of the gas turbine, indicating a surface temperature and a pressure of the high-temperature components of the turbine on the molten salt map to determine a superposition state thereof on a region of molten salt in a liquid phase, predicting a lifetime of the high-temperature components of the gas turbine by estimating a corrosion rate thereof, and controlling the flow rate of the low-quality fuel supplied to a combustor on the basis of the prediction of the lifetime of the high-temperature components so that an area of surface temperature and pressure regions of the high-temperature components superposing on the region of molten salt in the liquid phase on the molten salt map is reduced.
    • 一种用于燃气轮机的操作控制方法,包括以下步骤:通过计算用于对涡轮机的高温部件造成高温腐蚀的熔融盐的露点和固相线温度,使熔融盐图形成液相状态 使用基于低质量燃料中包含的杂质和燃气轮机的操作数据的热力学平衡计算的杂质,表示在熔融盐图上的涡轮的高温组分的表面温度和压力,以确定 其在液相中的熔融盐区域上的叠加状态,通过估计燃气轮机的腐蚀速率来预测燃气轮机的高温部件的寿命,以及控制供给到燃烧器的低质量燃料的流量 在预测高温部件的寿命的基础上,使得高温部件的表面温度和压力区域的面积 在熔盐图上液相中的熔融盐区域上叠加的成分分量降低。
