摘　　要：针对发电厂600 MW机组SCR脱硝系统投产后出现氨消耗量明显偏高的问题,在加强日常检修管理的同时,开展了一次风母管压力优化试验。通过试验寻找出一次风母管压力参数控制的最优值,在不影响制粉和炉内燃烧的同时,达到了降低SCR系统氨消耗量和厂用电率的目的,为同类型机组SCR系统优化运行提供参考。The ammonia consumption is significantly higher after the SCR denitrification system production in the 600 MW unit ofBaiyinhua power plant. According to the problem, the power plant strengthens the daily maintenance management and carries out a windpipe pressure test optimization. Through the experiment, the power plant finds out the primary air pipe pressure control value of the op-timal parameters without affecting the normal combustion and pulverizing. It reduces the consumption of ammonia SCR. These measuresprovides a reference for the optimization of the operation in the same type of unit SCR system.
