受多方面因素的制约,目前还很难直接测量燃气轮机的运行初温,在许多情况下需采用理论方法确定。本文依据热力学和燃烧学基本原理,结合燃气轮机设备和系统的一些具体情况,提出了四种较切合工程实际的确定运行中燃气轮机初温的方法,并对每一种方法的使用作了分析。 Constrained by many factors, it is still very difficult to directly measure the initial operating temperature of the gas turbine, and in many cases it needs to be determined by theoretical methods. Based on the basic principles of thermodynamics and combustion, combined with some specific cases of gas turbine equipment and systems, four methods to determine the initial temperature of gas turbine in operation are proposed, which are more suitable for engineering practice. The use of each method is analyzed.
