摘要

根据火用平衡方程、利用火用效率对汽轮机组给水加热系统进行了分析

给出了汽轮机组热力系统通用火用矩阵方程。该方程反映了热力系统对机组热经济性的影响

构造简单

不仅可以简化传统的汽轮机组热力系统火用的计算

为编制通用汽轮机组热力系统计算程序提供了依据

而且为汽轮机组热力系统火用分析特别是为进行局部的定量火用分析提供了理论依据。

Abstract

Based on exergy balanced equation

the feed-water heating system of one steam turbine unit has been analysed by using the exergy efficiency

the general exergy matrix equation used for thermodynamic system of the steam turbine unit being given.The said equation reflects the influence of the thermodynamic system upon the thermal economic efficiency of unit

its structure being simple

not only simplifying the traditional exergy calculation of thermodynamic system of steam turbine unit

but also providing basis for drawing up the calculation programme of thermodynamic system for a general unit

as well as providing theoritical basis for exergy analysis of the thermodynamic system for steam turbine units

especially for carrying out localized quantitative exergy analysis.
