火电机组热力系统抽汽等效热降矩阵算法

Matrix Calculating Method of Extraction Steam Equivalent Heat Drop in Thermal System of Fossil Fired Power Sets

在对热力系统进行局部定量分析之前首先需要确定新蒸汽的等效热降和各级抽汽的等效热降。各级抽汽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火电厂热力系统抽汽等效热降的矩阵算法,利用该方法能够迅速准确计算出不同热力系统各级抽汽等效热降,具有很好的通用性。

It is necessary to ascertain equivalent heat drop of live stream and each extraction steam before the partly quantitative analysis of thermal system. Based on linear algebra theory, with deeply study of equivalent heat drop theory, a matrix method of calculating each extraction steam equivalent heat drop is 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.
