摘要
本文利用计算机对现有燃气轮机注蒸汽的改装性能进行了模拟计算.考虑具体燃气轮机各部件性能影响,给出模拟计算的模型及对日本S1A-02型燃气轮机注蒸汽改装性能模拟的结果.分析表明,在现有的燃气轮机进行注蒸汽改装时,其首要的限制条件是压气机的喘振裕度,因而最佳注汽量的选择方式与一般的注蒸汽循环计算中的选择方式有所不同.本文还讨论了原机参数对余热锅炉设计参数的影响.
The computation on the performance of an extant gas turbine refitted with steam injection has been made by computer.The effects of the vari-ous parts of the gas turbine on the performance are considered,the simulant model and the result of a Japanese SIA-02 gas turbine with steam injec-tion are presented.The analysis for the result shows that the main consi-deration for the refitting with steam injection is the surge limitation of the compressor, and that the selection to optimum quantity of injected steam is different from that of general cycle calculation method.The eff-ects of the parameters of the gas turbine on the parameters in the design of the waste boiler are discussed.
