| 摘 要： | 针对常规的汽轮机理想循环热效率受到汽轮机本体相对内效率的影响而不能准确反映汽轮机回热系统运行热经济性的问题，对汽轮机理想循环热效率定义方法进行了改进，并对改进后的汽轮机理想循环热效率进行了分析。指出改进后的汽轮机理想循环热效率不仅能准确反映汽轮机回热系统运行经济性的变化，而且不受汽轮机本体相对内效率的影响，从而更适合于对汽轮机的热经济性进行诊断。

| Abstract: | Aimed at the problem that the conventional reheat steam turbine ideal cycle thermal efficiency is affected by steam turbine relative internal efficiency and it can't accurately express the thermal economics for regenerative system of steam turbine,the conventional defining method of ideal cycle thermal efficiency is improved.And the analysis on the new ideal cycle thermal efficiency is done.The viewpoint is pointed out that the new ideal cycle thermal efficiency not only can accurately express the change of the thermal economics for regenerative system but also is not affected by relative internal efficiency.So it is more fit for thermal economics diagnosis of steam turbine. |
