火电厂环保排放口稀释抽取式CEMS系统工作原理及影响因素

Working Principle and Influencing Factors of Dilution Extraction CEMS System of Environmental Protection Discharge Port in Thermal Power Plant

目前,全国已全面实施环保超低排放和近零排放标准,石油、化工、火电厂等的废气排放口环保仪表的稳定运行和准确测量尤为重要。以目前最受欢迎的稀释抽取式气态污染物CEMS为例,对其进行全面的介绍。

At present,the national environmental protection ultra-low emission and near-zero emission standards have been fully implemented,the stable operation and accurate measurement of environmental protection instruments at exhaust gas discharge ports of petroleum,chemical and thermal power plants are particularly important.As an example,the most popular dilution extraction gaseous pollutant CEMS is introduced in this paper.
