摘要
为了解决火电厂脱硝出口NOx和NH3浓度测量误差过大的问题,文章介绍了一套压差式自回流NOx网格取样系统。系统应用结果显示,网格取样装置测量的平均值与烟囱排放口在线测量的结果很接近。
In order to solve the problem of excessive measurement errors of NOx and NH3 concentrations at the denitration outlet of thermal power plants,a set of differential-pressure-type self-refluxing NOx grid sampling system was introduced.The results of the system application showed that the average value measured by the grid sampling device was very close to the online measurement result of the stack discharge.
