摘要
河北国华定洲发电厂3号机组为国内首台取消旁路并保留有独立增压风机的660 MW超临界空冷机组,其脱硫系统的试运过程与其他机组有很大不同。介绍了定洲电厂3号机组湿法烟气脱硫装置封闭旁路后的试运过程,阐述了因旁路封闭引起的系统问题和解决方案,并重点分析脱硫系统影响主机可靠性的各项因素,为机组取消旁路等提供参考。
Hebei Guohua Dingzhou Power Plant Unit No.9 is China＇s first 660 MW supercritical and air-cooling system equipped with independent booster fans and with the WFGD bypass system closed;and its trial operation is different from other units.This paper introduced the trial operation process,analyzed problems caused by cancellation of bypass and proposed corresponding solutions,and emphasized on the influence on the reliability of the major unit,which provides reference for other cases of bypass cancellation.
