摘　　要：针对火电厂脱硝出口NO_x和NH_3浓度测量准确度不高的现象,研究了一套适合脱硝装置出口CEMS的取样装置-分区取样系统。该系统应用结果显示:取样箱上NO_x的测量值与网格法测量平均值以及烟囱入口处在线测量结果都很接近;布置在取样箱上的NH_3在线分析仪表行情况读数稳定。In view of the low accuracy of NOx and NH3 concentration measurement in denitrification exit of thermal power plant, a set of sampling system, which is suitable for the CEMS of the denitrification device, is studied. The application results of the system show that the measured value of NOx on the sampling box is close to the average value of the grid method and the on-line measurement results at the entrance of the chimney, and the readings of the NH3 on-line analysis instrument on the sampling box are stable.
