燃气-蒸汽混合循环热力学分析

THERMODYNAMIC ANALYSIS OF STEAM INJECTED GAS TURBINE CYCLE

燃气-蒸汽混合循环装置因其具有高效率、高比功、变工况性能好等特点,越来越受到人们的重视。混合循环的性能与很多因素有关,这些因素之间也存在着相互作用和相互影响。本文对进入燃气轮机的燃气和水蒸汽的混合物(湿燃气)热力性质计算方法进行了探讨;编制了关于混合循环的计算机程序,并采用它分析了各循环参数对循环性能的影响。对联合循环和混合循环进行了比较分析。

With regard to steam injected gas turbine (STIG) cycle the authors have discussed the calculation method for the working medium (gas-steam mixture) thermo-dynamic properties. On this basis a STIG cycle computer program was given, with which the influences of various parameters on cycle performance were analyzed. A comparison analysis between the STIG cycle and the gas-steam combined cycle has been done.
