The Analysis of Effect on the Heat Conduction Oil Smoke Ingredients by Different Ignition Ways

This article analyzes the smoke ingredients of heat conduction oil by Gas Chromatography-Mass Spectrometer (GC-MS). Meanwhile, the effect on smoke dust ingredients by two different ignition ways of touching high-temperature surface and wick will be compared. Moreover, the different influences on the smoke by diverse extracts are studied as well. The result shows that n-hexane has better effect than aether. Heat conduction oil produces more polycyclic aromatic hydrocarbon (PAH) by the way of touching high-temperature surface and it produces more oxidizing materials by the other way. The research can provide a certain assistance for the analysis of the combustion of the heat conduction oil in fire physical evidence identification.
