摘要

对国电河北龙山发电有限公司2×600 MW空冷机组空冷岛的调试中出现的问题进行了分析

如冬季停机后起动空冷岛真空下降过快

全部空冷风机全负荷运转

汽封系统漏空气空冷岛背压急剧上升等

给出了调试中对上述问题采取的相关防范措施

并对调试中部分未能解决的问题

提出了具体建议。

Abstract

The problems appeared in commission debugging of the air-cooled island systems for two 600 MW air-cooled units of Guodian Longshan Power Generation Co Ltd

such as undue fast vacuum drop in air-cooled island during start-up of said units after their shutdown in winter

the rapid rise of back-pressure in said air-cooled isrand due to full-load operation of all cooling air fans and air-leakage in the steam seal system

etc.

have been analysed

and corresponding preventive measures adopted for above-mentioned problems in the commission debugging process being given.Regarding to a part of problems

which hadn't been solved in debugging

some concrete recommendations have been put forward.
