著者认为现有对具有正压锅炉的蒸汽燃气联合循环的最佳参数分析方法有两种,都有一定的缺陷,一种是所谓多变数的直接计算法,它的缺陷是计算繁复而且未能从特殊提高到一般,缺乏较普遍的指导意义;另一种是具有不同理想假设的理论分析的方法,其缺陷是未能把一般的理论更好地与实际相联系。本文介绍了所建议的介乎二者之间的一种方法:联x或三角形循环的代替方法。采用了联x的代替方法以后,可以把原有的蒸汽循环无任何变动地与联合循环中的其余部分(联x)完全分开。这样,对于分析、比较和确定联合循环中的最有利参数都大大地简化了,而且也从此作出了若干带有一般性意义的结论。
The author believes that there are two kinds of optimal parameter analysis methods for steam-gas combined cycle with positive pressure boilers, which have some defects. One is the so-called direct calculation method of multivariate. The disadvantage is that calculation is complicated and fails From special to general, there is no universal guiding significance. The other is the theoretical analysis method with different ideal hypotheses. The defect is that the general theory can not be better related to reality. This article presents a suggested method in between: an alternative to associative x or triangle loops. With the alternative method of coupling x, the original steam cycle can be completely separated from the rest of the combined cycle (x) without any change. In this way, the most advantageous parameters for the analysis, comparison and determination of the combined cycle are greatly simplified and several general conclusions are made.
