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。
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.
