摘　　要：目前SCR脱硝工艺存在氨源不稳定、稀释空气风量不稳定与加热系统工作效率差等问题。将NH3源换成蒸氨塔产生的氨气,增加了风机与稀释空气加热器,实现了SCR脱硝工艺稳定高效运行。Current SCR DeNO_(x)processes face issues with unstable ammonia sources,unstable dilution air flowrate,and poor heating system efficiency.By replacing the NH3 source with ammonia gas produced from ammonia stripper and providing fans and dilution air heaters,stable and efficient operation of the SCR DeNO_(x)process was achieved.
