非再热机组热系统分析的热/汽耗变换系数法

A Method for Non-Reheating Rower Plant Thermal System Analysis-Method of Conversion Cefficient of Heat/Steam Rate

热（汽）耗变换系数是在功率不变时导出的分析热力系统的重要参数，它代表了汽轮机回热抽汽的品位，利用这两个参数就能帮助对电厂热力系统的热经济性进行评价，用于优化电厂热力系统的结构。这两个参数的求取完全采用矩阵方法，特别适合于计算机运算。

The two important parameters (conversion coefficients of heat rate,ξ i and steam rate,k i)for analysing thermal system are obtained under the condition of constant output.The quality of turine regenerative steam-drawing can be represented by them.The thermal economy and structure for power plant thermal system can be caculated and improved with them.They are calculated with matrixmethod,that is particularly suitable for computer processing.The principle for computing these two parameters for non-reheating power plant themal system is presented in this paper.A condensing unit of 100MW is taken as an example to show the correctness of the method.
