汽轮机回热系统加热器给水焓升优化分配方法对比分析

The Approach and Analysis of Optimal Distribution of Feed-water Enthalpy rise for Steam Turbine

以火电机组热力系统为研究对象,通过分析现有各种典型焓升分配方法,得出了各种方法存在的问题。并结合国内某汽轮机回热系统,对给水焓升分配进行了计算对比,为今后进一步研究加热器焓升最优分配问题奠定了基础。

The research object is locked in coal power heating system. The defects of the existing optimal distri- bution of feed-water enthalpy rise are analyzed in this paper, and the problem is given. Then regenerative system for the domestic 300MW steam turbine was calculated by programming. This paper is the basis of further study the problem of optimal distribution of feed-water enthalpy rise.
