摘要

根据超临界660MW直接空冷机组的特点

在调试期间对其主要附属系统如汽封系统、真空系统、凝结水系统、给水系统、直接空冷系统等从设计、运行等方面进行了优化改进。优化改进后

消除了附属系统的不经济因素

较大地提高了机组的经济性。

Abstract

Based on features of the supercritical 660 MW direct air cooling unit

the optimized retrofit of its main auxiliary systems

such as the steam seal system

the vacuum system

the condensate system

the feed-water system

and the direct air cooling system etc.

have been carried out in aspects of design and operation etc.

during the debugging period in capital construction.After retrofitting

the non-economic factors of said auxiliary systems have been eliminated

the economic efficiency of unit being greatly enhanced.
