燃煤电厂脱硝烟气稀释法测量技术故障探究

Research on Technical Failure of Dilution Method Measurement of Flue Gas Denitration in Coal-fired Power Plant

稀释法作为超低排放大趋势下CEMS测量的主流技术,优势日趋明显。文章在介绍一种烟气稀释法测量原理的基础上,结合多年CEMS维护经验,提出了几种典型的故障及处理方法,并列举了案例。

The dilution method,as the mainstream technology of CEMS measurement under the great trend of ultra-lowemissions,shows a obvious advantage.Based on the presentation of measurement principle of dilution method of a flue gas,the paper combines maintenance experiences with CEMS for many years,and puts forward several typical common faults andprocessing methods as well as lists the cases.
