烟气脱硝系统在寒冷地区建设及运行总结

摘要

根据国家现行的燃煤机组污染物排放标准,采用液氨-SCR脱硝工艺是比较稳定和经济的选择,本文介绍了多机组并存,寒冷地带脱硝系统改造、调试和稳定运行及制氮系统在寒冷地区SCR供给站建设的必要性.%According to the national standard of coal-fired units of pollutants,the liquid ammonia-SCR process is relatively stable and economic technology choice,many units,cold denitration system, debugging,and stable operation,nitrogen system is the necessity of SCR supply station construction in cold region.
