摘要
以NH3为还原剂,采用选择性催化还原法对上海某燃煤电厂烟气进行脱硝处理。运行结果表明,该工艺处理效果稳定,烟气出口NOX质量浓度平均值为59.71 mg/m3,满足《火电厂大气污染物排放标准》(GB 13223—2011)中浓度限值要求;项目年减排NOX(以NO2计)2 530.74 t,收益为2 224.30万元,其环境效益及经济效益显著。
The flue gas of coal-fired power plantis treated by SCRprocess,regardingNH3as the reducing agent.The operational results show that the process is efficient and stable.The average value of outletNOX is59.71 mg/m3,which canmeet the emission standard of airpollutantsforthermal powerplants(GB 13223— 2011).The benefits of environment and economy are considerable,which could reduce 2 530.74 tons of NOX and save 2 224.30 Chinese Yuan every year.
