600MW超临界机组光热耦合发电方案研究

Research on Photo-Thermal Coupling Power Generation Scheme of 600 MW Supercritical Unit

随着我国火力发电的发展,600MW等级超临界、超超临界机组已成为主力机组,做好600MW超临界的节能降耗有着重要的现实意义。本文分析了我国太阳能资源分布情况,提出了利用太阳能光热设备耦合机组热力系统发电方案,达到机组节能降耗的目的。文中针对600MW超临界机组热力系统设计了2种耦合发电方案,分别进行了理论计算,得出综合效益最佳方案,为机组节能改造实施提供理论依据。

With the development of thermal power generation in China,600MW supercritical and ultra-super⁃critical units have become the main units.It is of great practical significance to do a good job in energy sav⁃ing and consumption reduction of 600MW supercritical unit.This article analyzes the distribution of solar en⁃ergy resources in China,and proposes a power generation scheme using solar thermal equipment coupled with thermal system to save energy and reduce consumption.In this paper,two coupling power generation schemes are designed for the thermal system of 600 MW supercritical unit,and the optimal scheme of com⁃prehensive benefits is obtained by theoretical calculation respectively,which provides the theoretical basis for the implementation of energy-saving transformation of units.
