摘要
燃气轮机燃气透平应运行在设计的进气温度下,以保证燃气轮机热通道部件较长的使用寿命和运行经济性。由于燃气透平进气温度很高且无可靠仪表进行直接测量,因此采用了热平衡方法进行间接计算。经在多台大型燃气-蒸汽联合循环机组性能考核试验中应用证明,使用热平衡方法间接计算燃气透平进气温度切实可行。
The gas turbine incoming gas temperature should be maintained at lower than 130℃ in operation, so as to ensure longer service life and better economic efficiency of the parts situated in thermal passage of the gas turbine. In view of the incoming gas tem- perature being too high and still hasn＇t reliable instrument for directly measuring the said gas temperature,hence,an indirect calcula- tion method of the incoming gas temperature has been carried out by using the heat - balancing method. This method has already used for performance assessment test of many large - capacity combined cycle units. Proving it is reliable and feasible.
