凝汽式机组回热系统矩阵模型的建立及应用

Establishment and Application of the Matrix Model for Heat Regenerative System of Condensing Unites

热力系统是电厂节能降耗理论分析的基础,回热系统是现代火电厂热力系统的重要构成部分。通过对回热系统的分析,考虑到每级加热器可能出现的辅助汽水系统、外加出入热源等进行深入研究,采用矩阵解析思路从而建立模型。

Thermodynamic system is the basis of analyzing the theory of energy saving and consumption reduction of power plant, and heat regenerative system is an important part of thermodynamic system in modem power plant. This paper emphasizes on building models with matrix analytical method for heat regenerative system, especially the occurrence of auxiliary steam and water system and external heat source in each stage of heaters are also taken into consideration.
