CEMS在燃煤机组超低排放改造中的选型与应用

Selection and application of CEMS in ultra-low emission reformation of coal-fired plant

目前大力推广的现役燃煤机组超低排放改造对CEMS测量的准确度和精度都提出了更高的要求。针对超低排放改造后烟气湿度大、污染物排放浓度低的特性,结合山西大唐国际运城发电有限责任公司2号机组(600 MW)超低排放改造,重点介绍了CEMS的选型、特点及应用。根据数据比对监测结果分析,该CEMS系统的准确度和误差范围均满足国家环保规范。

Higher demands for CEMS in terms of accuracy and precision have been proposed with the wide and vigorous promotion of ultra - low emission reformation in coal fired plant in China. Combined the features of low emission concentration and high humidity of flue gas, theselection, characteristicsand applicationof CEMS on Shanxi DaTang international YunCheng power generation of unit 2 that has ultra - low emission reformation have been introduced. According to the results of comparison testing, it is demonstrated that the accuracy and preci- sion of CEMS selected can monitor the pollutant concentration and smoke parameters accurately and objectively and can meet the national environmental standards at the same time.
