摘要
某F级燃气电厂运行中发现NOx数值存在较大波动,通过分析和排查,发现烟气分析仪存在老化现象,同时CEMS仪表间存在布置不合理情况,通过处理NOx数值波动得以有效改善,可为同类电厂烟气系统数据异常处理提供参考。
There is a great fluctuation in the NOxvalue of a F grade gas power plant. Through analysis and investigation,it is found that there is an aging phenomenon in the flue gas analyzer. At the same time,the layout of the CEMS instrument is not reasonable,and it can be effectively improved by dealing with the numerical fluctuation of the NOx. It can provide reference for the abnormal processing of the data of the smoke system of the same kind power plant.
