摘　　要：脱氮率随尿素质量分数的增大而逐渐增大,尿素含量为20%较适宜;添加剂三乙醇胺能提高脱氮率,当其含量从0.05g/L到0.15g/L时,脱氮率由74%提高到87%;当烟气流量大于0.4 m3/h,脱氮率开始快速下降。烟气流量从0.3 m3/h增加到0.6 m3/h,脱氮效率降至64%,下降了12%。The efficiency of removal NOx from flue gas increases with increasing the urea concentration. It is the most suitable when its concentration is 3%. The removal rate increased from 74% to 87% when triethanolamine concentration from 0.05g/L to 0.15g/L. The removal efficiency declined rapidly as the flow of flue gas is heavier than 0.4 m^3/h. And it declined to 64% by 12% when the flow of flue gas increased from 0.3 m3/h to 0.6 m^3/h.
