摘要: 本文以注蒸汽燃气轮机系统(STIG)为研究对象，运用Aspen plus软件对该系统进行模拟，并对其进行了热力性能分析。着重讨论了压比、注蒸汽比以及透平进口温度对系统的热力性能的影响规律。通过计算分析，得出了注蒸汽轮机系统的最佳注蒸汽量和最佳压比，并与普通燃气轮机进行对比，证明了注蒸汽燃气轮机的优越性。另外，还得到了一个最佳的状态点，即透平进口温度为1300˚C，压比为34，注蒸汽比为0.2，该状态点对应的系统的比功率较大，发电效率最大，可达53.91%。在实际工业中，在进行注蒸汽燃气轮机的参数设计时，可以参考本文得出的最佳参数值。
Abstract: The steam injection gas turbine system (STIG) is studied in this paper. The system is simulated by using Aspen plus software, and its thermal performance is analyzed. The influence of pressure ratio, steam injection ratio and turbine inlet temperature on the thermal performance of the system is discussed. Through a series of calculation and analysis, the optimum steam injection rate and the optimum pressure ratio of the steam injection gas turbine system are obtained, and the superiority of steam injection gas turbine is proved by comparing with common gas turbine. In addition, we also get an optimum state point with the turbine inlet temperature of 1300˚C, the pressure ratio of 34, the steam injection ratio of 0.2. At this state point, the specific power is larger and the maximum generation efficiency can reach 53.91%. When steam injection gas turbine is designed to be applied to actual industry, the optimum parameter values obtained in this paper can be taken as a reference.
