分析法在动力装置循环中的应用及其优点

在对各类动力装置及其循环的分析中,采用较多的是传统的热效率计算方法,得出循环的热效率及其热流分配,但它不能直接反应装置中各部分不可逆因素引起的作功能力损失以及整个循环总的作功能力损失,而火用分析正好弥补了这个缺点。在工程上利用火用分析法为节能提供了可靠的线索。

The analysis to all kinds of power plants and the energy cycle, in order to gain the heat efficiency and the apportionment of heat flux, it is the traditional heat efficiency method that we usually take. But it can＇t directly express the loss of the work ability in all parts of the unit because of the irreversibility, meanwhile the total loss of the work ability in the cycle. While, to the method of exergy analysis, it is the advantage in the analysis of the loss of the work ability. It supplies reliable clue for energy saving by using the exergy analysis in project.
