燃气轮机起动是机组可靠性的主要指标之一。本文用相似理论分析了大气参数变化和起动设备更换时对起动工况的控制方法。其结论与单轴机组长期运行的数据基本一致。 一、单轴燃气轮机的相似工况和理想起动过程 燃气轮机起动过程中的燃料控制对起动的成败有决定性的作用。很多机组随着压气机、透平气动性能变差和起动设备的出力下降使起动问题日趋尖锐。尤其是在气温较高的夏季中午,往往是起动时间延长,产生“热挂”,甚至起动失败。单轴燃气轮机运行工况
Gas turbine starting is one of the main indicators of unit reliability. In this paper, the similar theory is used to analyze the change of atmospheric parameters and the control method of starting condition when the starting equipment is changed. The conclusion is consistent with the data of long-term operation of uniaxial units. First, similar conditions and the ideal start-up process of a single-shaft gas turbine Fuel control during start-up of a gas turbine has a decisive effect on the success or failure of the start-up. Many units with the compressor, turbine deterioration of the aerodynamic performance and the decline in the output of the starting equipment to start getting increasingly sharp problem. Especially in the hot summer noon, it is often the starting time is extended, resulting in “hot”, or even start failed. Single-shaft gas turbine operating conditions
