The results confirm that NH3 slip increases with both higher ratio of NH3 to NO n(NH3/n and higher concentration of a reducing reagent, while it decreases with the increase of temperature. Initial NO concentration and its residence time can also affect the NH3 slip. A higher initial NO concentration lead to higher NH3 slip, but added residence time has the opposite effect. Among urea, ammonium carbonate and ammonia liquor, the NH3 slip of urea is the highest and that of ammonia liquor is the lowest.

试验结果表明：温度越高，漏失氨含量越低；随氨氮物质的量比的增加，NH3漏失含量不断增加；还原剂质量浓度越低，NH3漏失含量越低； NO初始浓度和停留时间对漏失氨浓度也有影响，NO初始浓度越高NH3漏失浓度越高，停留时间越长漏失氨浓度越低；不同还原剂NH3漏失浓度不同，尿素、碳酸氨、氨水3种还原剂中，尿素的NH3漏失浓度最高，氨水的NH3漏失浓度最低。
