摘要
介绍了厌氧沼气发电烟气的特点,采用10%尿素溶液作还原剂,在400~450℃使用选择性催化还原脱硝(SCR)进行烟气脱硝,将初始NO_(x)自410 mg·Nm^(-3)降至10 mg·Nm^(-3)以下,并介绍了尿素量计算及SCR催化剂的选型。
The characteristics of biogas generator flue gas from the anaerobic process was introduced,and 10%urea solution was used as reducing agent for the selective catalytic reduction denitration(SCR)under the condition of 400~450℃.Finally,the NO_(x) mass concentration was reduced from 410 mg·Nm^(-3) to below 10 mg·Nm^(-3).And the calculation of urea quantity and the selection of SCR catalyst were introduced.
