摘　　要：普通煤油作为日常及工业中常用的液体燃料,其燃烧过程及排放特性的研究显得尤为重要。本文采用实验和表征的方法,搭建煤油燃烧实验平台,利用热泳技术进行碳烟颗粒采集,利用透射电镜、XPS等技术进行碳烟颗粒表征。结果表明:(1)普通煤油在燃烧过程中,其火焰中碳烟生成符合颗粒成核、表面生成、团簇凝聚、颗粒氧化等碳烟颗粒物的演变规律;(2)火焰外生成碳烟中,官能团最多的为C=C,达到60.71%,而碳烟颗粒中的氮化物含量都较小,但吡啶含量远高于其他氮化物;(3)在火焰外碳烟颗粒粒径分布在91.28nm~341.99nm之间,相比于火焰内利用TEM图像统计的碳烟颗粒粒径明显增大;(4)在热重实验中,氮气气氛下,碳烟颗粒在567℃时,发生质量转折式下降。As a liquid fuel commonly used in daily life and industry,the study of combustion process and emission characteristics of ordinary kerosene is particularly important.In this paper,the methods of experiment and characterization were used to set up an experimental platform for kerosene combustion,and thermal swimming technology was used to collect carbon soot particles,and transmission electron microscopy,XPS and other technologies were used to characterize carbon soot particles.The results show that:(1)The soot generation in the combustion process of common kerosene conforms to the evolution law of soot particles such as particle nucleation,surface formation,cluster agglomeration and particle oxidation;(2)In the carbon smoke generated outside the flame,the most functional group is C=C,reaching 60.71%,while the nitride content in the carbon smoke particles is small,but the pyridine content is much higher than other nitrides;(3)The particle size distribution of soot particles outside the flame ranges from 91.28 nm to 341.99 nm,which is significantly larger than that of soot particles inside the flame according to TEM image statistics.(4)In the thermogravimetric experiment,under the nitrogen atmosphere,the carbon smoke particles at 567℃,a turning mass decline.
