传统的燃煤电厂历来被视为大气污染物的主要来源，是国家环保监管的重点。国内首套烟气超低排放装置在浙能嘉兴发电厂8号机组投入运行后，主要污染物排放指标基本都达到了天然气燃气机组的排放标准，特别是氮氧化合物的排放全时段控制在50mg/Nm3以下[1]。本文介绍了嘉兴电厂百万燃煤机组烟气超低排放环保示范项目实施后，热控专业针对系统中存在的问题对脱硝系统CEMS测量、脱硝自动控制策略等方面进行了一些措施改进，并针对项目实施过程中遇到的问题进行了探讨。
傳統的燃煤電廠歷來被視為大氣汙染物的主要來源，是國傢環保鑑管的重點。國內首套煙氣超低排放裝置在浙能嘉興髮電廠8號機組投入運行後，主要汙染物排放指標基本都達到瞭天然氣燃氣機組的排放標準，特彆是氮氧化閤物的排放全時段控製在50mg/Nm3以下[1]。本文介紹瞭嘉興電廠百萬燃煤機組煙氣超低排放環保示範項目實施後，熱控專業針對繫統中存在的問題對脫硝繫統CEMS測量、脫硝自動控製策略等方麵進行瞭一些措施改進，併針對項目實施過程中遇到的問題進行瞭探討。

The traditional coal-fired power plant has been regarded as the main source of air pollutants, and became the focal point of national environmental protection. As the ifrst ultra-low lfue gas emission devices put into operation in the 8th generator unit in Jiaxing power plant of Zhejiang provincial energy group company, the main pollutant emission indicator has up to the standard of natural gas generator units, especially the NOx emission has been controlled below 50 mg/Nm3 all time[1]. The thermal-control team has reformed the existing problems in the CEMS measurement of DeNOx system, the DeNOx automatic control tactics and so on, since the ultra-low emission environmental demonstration project implemented in 1000MW coal-ifred units in Jiaxing power plant. This paper discusses this improvement measures and problems in the progress of project operation.
