【摘要】 本文就“与分析”一文中有关蒸汽动力循环中确定最优给水焓值的讨论持有不同的看法。[1]文认为对于抽汽回热给水蒸汽动力循环来讲,“（火用）分析得到的最优给水焓值i_sn,要比传统的焓分析得到的值低。所以根据（火用）分析的结果,可以选取更为合理的给水焓值。”为此本文用焓分析及（火用）分析的方法探讨了该问题。结论是:对同类型的蒸汽动力循环来讲,在相同的前提下,无论用（火用）分析还是用焓分析寻求最佳参数时,结论是一致的,不存在何者更为合理的问题。且指出了[1]文之所以得到这一不确切结论的根由。更多还原

【Abstract】 This paper deals with the differences of opinions between the author of "Exergy & Exergy Analysis" [1] and the authors of the present paper in determining the optimum enthalpy of feed water in a steam power circulation. The author of paper [1] holds the view that the optimum enthalpy of the feed water obtained from exergy analysis is lower than that from conventional enthalpy analysis. So, according to the conclusion of exergy analysis, it is better to take the lower enthalpy of the feed water The method of enthalpy analysis and that of exergy analysis are both employed in this paper to discuss the same problem and we arrived at a conclusion that, to the same kind of steam power circulation operating at the same condition, no matter whether the method by exergy analysis or enthalpy analysis we used to find the optimum parameter, the conclusion is just the same. There is no question of one being better than the other. We would like to also point out the reason here why the author of paper [1] arrived at the undefined conclusion.更多还原
