锅炉烟气超净排放项目中CEMS应用探讨

摘要

介绍了新的污染物排放标准中特征污染物的排放极值的新要求,讨论了烟气排放连续监测系统(CEMS)如何在污染物的质量浓度超低范围应用于工程项目的问题,着重介绍了直接抽取法和稀释抽取法的测量原理及在超低质量浓度测量中的应用,针对超低排放的工况条件、采样过程的特殊性,提出了在污染物的质量浓度超低情况下CEMS应用的注意事项与发展改进新思路.%The new requirements for emission extremes of characteristic pollutants in new pollutant emission standards are introduced.How to apply continuous emission monitoring system(CEMS) to engineering project in ultra-low mass concentration range of pollutant is discussed.The measuring principle of direct extraction sampling and diluted extraction sampling and application under ultra-low mass concentration are stressed.On the part of particularity of working condition and sampling process of ultra-low emission,the new development ideas and attention of CEMS application in ultra-low mass concentration of pollutant are put forward.
