摘　　要： 采用自制燃烧实验平台,考察了燃烧温度和空气流量对生活垃圾(MSW)燃烧过程中CO和NO排放特性的影响,并与Logistic数学模型预测结果比较.结果表明,CO排放呈先增后减的单峰曲线,CO平均浓度和峰值浓度随燃烧温度提高先减小后增大,峰值前移,燃尽时间缩短;CO平均浓度随空气流量增加而减小,峰值后移,燃尽时间增加;空气流量13.3 L/min、燃烧温度800℃时,CO的平均浓度最小为44.56 mg/m^3.NO排放呈增大-减小-增大-减小的双峰形态,NO平均浓度和峰值浓度随燃烧温度和空气流量增加而增加,空气流量13.3 L/min、燃烧温度950℃时,NO的平均浓度最大为25.26 mg/m^3.Logistic模型能较好地描述燃烧过程中N析出率的变化. The effects of furnace temperature and air flow rate on characteristics of CO and NO emission from municipal solid waste （MSW） combustion was studied by using a self-made combustion experiment platform. The experimental datas were comparied with the predicted results of Logistic model. The results showed that the CO emission curves expressed single peak, the average concentration and peak values of CO increased first and then decreased, the peak moved forward and the burning time decreased with the temperature increasing. With the air flow rate increasing, the average concentration and peak values of CO decreased, the peak backwards, and the burning time increased. At the air flow rate and combustion temperature of 13.3 L/min and 800℃, respectively, the minimum average concentration of CO was 44.56 mg/m^3 . The NO emission curves had two peaks, the average concentration and peak values of NO increased with the temperature and the air flow rate increasing, respectively. The maximum average concentration of NO was 25.26 mg/m3 at the air flow rate and combustion temperature of 13.3 L/min and 950℃. The model of Logistic can well describe the N precipitation rate of the combustion process.
