废气CEMS在线比对监测中的问题及解决方案

The Problem and Solution of CEMS on Line Alignment of Waste Gas

简述了目前比对监测工作的依据以及比对监测现状,指出了比对工作的常见问题,如共性问题、颗粒物比对监测、二氧化硫比对监测、流速比对监测、合理选择比对方法等,提出了相应的解决办法,监测人员应对各种参比监测方法熟练掌握,了解各个企业的CEMS系统原理、方法和工况,在保证监测数据准确性的前提下提高比对工作的一致性。

This paper briefly described the current status and working principle of comparison monitoring. Common problems during work, such as particulate, S02, and flow rate comparison monitoring, as well as appropriate method selection were discussed. It was suggested that the monitoring personnel should be familiar with comparison monitoring techniques, and understand the CEMS system principles, methods, and status of different enterprises, to improve consistency of comparison work while ensure the accuracy of monitoring data.
