注蒸汽燃气轮机循环工质热力性质研究

Studv of Steam Injected Gas Turbine Cycle Working Medium Thermodynamic Properties

本文对注蒸汽燃气轮机循环中的工质,首先建立了燃气—蒸汽混合物(以下简称湿燃气)的理想模型;据此确立了湿燃气热力性质计算的二次线性插值方法。采用该方法,编制了供工程实用的湿燃气热力性质表及与之配合使用的理想水蒸汽表。

With respect to the working medium used in a steam injected gas turbine cycle the authors have established an ideal model of gas-steam mixture (referred to as wet gas for short), and on this basis come up with a secondary linear interpolation method for calculating wet gas thermodynamic properties. With the help of the said method a table of wet gas thermodynamic properties and also an ideal steam table to be used in conjunction with the former have been prepared, which are suitable for practical engineering applications.
