各级抽汽等效热降的简捷算法

在对热力系统进行局部定量分析之前需要首先确定新蒸汽的等效热降和各抽汽段的等效热降。由于各抽汽段等效热降的传统算法比较繁琐,通过深入研究等效热降理论,应用线性代数理论导出了一种求取各抽汽段等效热降的简捷算法,该方法能够针对不同的热力系统进行迅速准确的计算,适用于一次再热机组,非再热机组,供热机组及超临界二次再热机组等任何类型的机组,对于变工况运行也是适用的,具有很好的通用性。最后,采用该简捷方法,对某一次再热机组进行了验证。

Brief calculating method of each extraction steam equivalent heat drop

It is necessary to ascertain equivalent heat drop of live stream and every extraction steam before the partly quantitative analysis of thermal system. Based on linear algebra theory,with deeply study of equivalent heat drop theory,a brief method of calculating each extraction steam equivalent heat drop was given as to the fussy calculated process of traditional method.This brief calculating method has great universal performance;it can calculate rapidly and accurately as to different thermal system and diff...
