摘　　要：本文主要基于神福鸿电两台百万机组超低排放烟气在线监测系统,分析了烟气在线监测系统结构组成、测量原理,介绍了仪表本身高低量程切换原理以及实现方式。在机组停备、起动、运行期间分别进行了模拟试验,高低量程切换信号触发正常,仪表本身模拟量高低量程切换正常,机组不同工况下环保参数监视正常。Based on the on-line monitoring system of ultra-low emission flue gas for two million units of Shenfuhong Electric Power Station,this paper analyses the structure and measurement principle of CEMS system,and introduces the principle of high and low range switching of the instrument itself and its implementation.Simulated tests were carried out during unit standby,start-up and operation.The high and low range switching signals triggered normally,the high and low range switching of the instrument itself was normal,and the environmental protection parameters of the unit were monitored normally under different working conditions.
