摘　　要：针对SCR脱硝系统运行存在的普遍问题,如脱硝系统出口NO_x浓度分布不均匀、催化剂磨损严重、供氨管道堵塞等,分别选取不同的典型案例,通过脱硝系统性能试验深入分析每个案例中问题产生的原因,同时提出相应的解决措施。In view of the common problems in the operation of SCR denitrification system, such as the nonuni- form distribution of NOx concentration at the outlet of the denitrification system, the serious wear of the catalyst and the clogging of the ammonia pipeline. Typical cases are selected in this article. The performance test of the denitrification system is used to analyze the cause of problem in each case, and the corresponding measures are put forward at the same time.
