摘　　要：在模拟的燃烧实验台上,通过提高氧浓度分析了富氧燃烧技术对陶瓷辊道窑能耗、废气排放、NOx和CO2浓度及窑炉火焰特性的影响。研究结果表明：柴油富氧燃烧后,在保证实验台内温度场稳定的前提下,随着氧浓度从21%-30%逐渐增加,沿火焰长度方向的热气体温度随距窑墙距离的增加而迅速降低,火焰流速变慢,火焰长度变短;柴油量在氧浓度刚开始升高时快速减少,随后减少幅度下降;理论废气量和CO2浓度逐渐减少,而NOx浓度则迅速增加。The Energy Comsumption,emissions,NOx and CO2 concentrations and flame characteristic in ceramic roller kiln were analyzed by increasing oxygen content on the burning test…bed.The results show that： when diesel is burning with oxygen enrichment combustion,in order to keep the temperature field stable,with oxygen content increasing from 21% to 30%,diesel quantity obviously decreasing in the beginning and then slower;the theory flue gas volume and the concentration of CO2 reduces,however NOx increases;The temperature of hot gas along axis of oxygen flame decrease rapidly with the distance to the kiln wall increasing,the velocity of hot gas slows,the length of flame shorts.
