在实验室规模的内循环流化床内进行城市垃圾焚烧实验，在线测量焚烧过程中NO和N₂O的排放特性，研究空气过量系数、添加钙基脱硫剂及城市垃圾与半焦混烧时不同混烧率对NO和N₂O排放特性的影响。研究结果表明，城市垃圾在流化床焚烧过程中随空气过量系数增加，NO和N₂O排放浓度都增加，且NO增加幅度大于N₂O；随Ca/（S+0.5 Cl）摩尔比增加，N₂O生成量逐渐下降；随着混烧燃料中城市垃圾混烧率增加，烟气中NO排放浓度增加，N₂O排放浓度逐渐下降。

The incineration experiments of refuse derived fuels (RDF) are conducted in an internally circulating fluidized bed with laboratory scale.The emission characteristics of NO and N₂O are measured on line during the incineration peocess.The effects of the excess air ratio,the molar ratio of Ca/(S+0.5Cl) and the co-firing ratio of RDF to semi-coke on the emission characteristics of NO and N₂O are investigated.The experimental results show that the emission concentrations of both NO and N₂O increase with the increase of the excess air ratio,and the growth for NO is larger than that of N₂O.The concentration of N₂O decreases gradually when the molar ratio of Ca/(S+0.5Cl) increases.With the inceasing RDF co-firing ratio in the mixed fuels,the emission concentration of NO in the flue gas increases while that of N₂O decreases gradually.
