300 MW循环流化床锅炉SNCR运行优化

SNCR Operation Optimization of 300 MW Circulating Fluidized Bed Boilers

按照新的环保排放要求,2014年7月开始,特别区域的NOx排放要控制在100 mg/m3,为了能够达标排放,米东热电厂于2013年进行了脱硝系统改造,在系统投运后一直存在尿素用量偏大,通过运行优化调整,脱硝还原剂用量大大降低。在保证满足环保指标排放的同时,也大大降低了脱硝成本。

In accordance with new emission requirements for environmental protection, the emission of NOxin special areas will be controlled to 100 mg/m3 starting from July 2014. In order to be able to discharge up to the standard, Midong thermal power plant reformed the denitration system in 2013. Since the system was put into operation, relatively large amount of urea had been used. The amount of denitrification reducing agent has been greatly reduced by the optimal adjustment of operation, which not only ensures that the emissions can meet the environmental targets, but also greatly reduces the cost of denitrification.
