聚甲氧基二甲醚3掺混对正戊烷反扩散火焰燃烧碳烟生成特性的影响研究
Study on effect of PODE3 addition on soot formation characteristics of n-pentane inverse diffusion flame
摘要
Abstract
Polyoxymethylene dimethyl ether(PODEn)is a promising alternative fuel for diesel due to its high oxy-gen content and high cetane number,thereby enhancing the thermal efficiency and reducing the pollutant emis-sions.In this study,an inverse diffusion flame was employed to investigate the effect of adding different concentra-tions of PODE3 on the soot formation characteristics of n-pentane combustion.The soot samples are analyzed by us-ing transmission electron microscope(TEM),Raman spectrometer,and X-ray diffractometer(XRD).The results indicate that with increasing PODE3 blending ratio,the average particle size of soot decreases,the average fringe length reduces,and the average fringe tortuosity increases.The ratio of the integrated intensity of D band to the G band in the first-order Raman spectrum,representing lattice internal defects and disordered structure versus stable graphite structures,gradually increases.Additionally,the interlayer spacing of the(002)crystal plane expands,and the degree of graphitization of soot decreases while the degree of disorder increases.关键词
