摘　　要：卷烟厂膨胀烟丝热端焚烧炉排烟应用烟气再循环低氮燃烧技术改造后,分别进行了空载和负载情况下的烟气污染物排放试验测试,结果表明:膨胀烟丝热端焚烧炉排烟应用烟气再循环低氮燃烧技术改造后,可减少天然气用量9%以上,节能显著;烟丝膨胀过程工艺废气携带的含氮化合物因烟气再循环被更彻底的热力分解为氮氧化物,生成量远大于烟气再循环低氮燃烧技术降低的热力型氮氧化物量,同时工艺废气携带的含碳化合物未充分燃烧生成的一氧化碳浓度可降低20%以上。基于测试数据和相关理论分析,膨胀烟丝焚烧炉应用烟气再循环低氮燃烧技术,配合利用一氧化碳还原性的催化脱硝技术,可以实现既节能又减排的目标,实现减少有机废气、氮氧化物、一氧化碳排放的综合效果。After the application of flue gas recirculation(FGR)and low nitrogen combustion technology in the gas exhaust of the expansion tobacco hot end incinerator in a cigarette factory,gas pollutant emission tests were conducted under no-load and load conditions.The results showed that after the application of FGR and low nitrogen combustion technology in the gas exhaust of the expansion tobacco hot end incinerator,the natural gas consumption can be reduced by more than 9%,and the energy saving is significant;The nitrogen-containing compounds carried by the exhaust gas of the tobacco expansion process are more thoroughly thermally decomposed into nitrogen oxides due to FGR,and the generated amount is much greater than the thermal nitrogen oxides reduced by the low nitrogen combustion technology of FGR.At the same time,the concentration of carbon monoxide generated by incomplete combustion of the carbon compounds carried by the process exhaust gas can be reduced by more than 20%.Based on test data and relevant theoretical analysis,the application of FGR and low nitrogen combustion technology in the expansion tobacco incinerator,combined with the catalytic denitrification technology of carbon monoxide reduction,can achieve both energy-saving and emission reduction goals,and achieve a comprehensive effect of reducing organic waste gas,nitrogen oxides,and carbon monoxide emissions.
