Summary
On this article, soot particles generated and discharged from the flame in the course of the kerosene combustion had been studied. The soot particles collected within the flame had been characterised by transmission electron microscopy, whereas the soot particles collected above the flame had been characterised by x-ray photoelectron spectroscopy, Fourier rework infrared spectroscopy, Raman, and thermogravimetric strategies. The outcomes present that with the rise of the sampling peak throughout the flame, the morphology of the soot particles step by step modified from viscous, linked dense state to well-defined particles which had been gathered to kind chain construction, and ultimately fashioned particle superposition. In the meantime, the soot particles primarily comprise 4 components of C, O, N, and H. The soot particles confirmed good oxidation exercise within the thermogravimetric evaluation in an oxygen setting. Alternatively, by heating in a nitrogen setting, after 567 °C, the soot particles had been topic to thermal degradation by self-oxidation with O-containing useful teams, involving bond rupture and restructuring to generate unstable substances.
