摘要

根据某660 MW机组回热系统结构及参数

给出了火用损分布矩阵方程。选取100%、75%、50%、30%负荷工况点

对回热加热器火用损和火用效率进行了定量计算与分析。结果表明

当传热量及加热器结构一定时

为了降低换热温差

则必须设法增大换热系数

如减小阀门阻力、提高工质流速等。

Abstract

Based on the structure and parameters of the regenerative system for one 660 MW unit

the matrix equation of exergy loss distribution has been given.Selecting operating condition point under 100%

75%

50%

and 30% load

the exergy loss and exergy efficiency of regenerative heater has been calculated.The calculation and analysis show that the heat exchange coefficient must try to be increased for reducing the temperature difference of heat exchange at certain heat transfer and heater structure

including decrease of valve resistance

and enhance of working medium flow speed

etc.
