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.
