摘　　要：实验研究了以天然气和氨为还原剂,在高温环境中对烟气中氮氧化物进行还原脱除。在这个过程中,通过改变再燃区的温度、过量氧系数、喷氨量、喷水蒸汽量等方法,提高再燃区的脱硝效率。通过实验研究对这些参数进行优化,并从机理上给予解释。本研究为其工业应用提供有价值的数据依据和理论基础。Experiments were carried out to study on the influences of parameters to de-NO by natural gas and ammonia injection under high temperature. The parameters include temperature, excess oxygen ratio, NH3 injection, water vapor content, etc. Many influences rules were found by the experiments, and their mechanism is explained. This will provide valuable data and theory foundation for the utility of this technology.
