翻译：In recent years， due to corrosion caused by sulfur oil refining， storage and transportation equipment， such as frequent accidents leaked to the business causing huge economic losses， analyze the cause of the accident found that iron sulfur compounds lead to the spontaneous combustion is the main reason for the This article study the oxidation of sulfide exothermic reaction product of activity of factors， from a theoretical and experimental analysis of sulfur exothermic oxidation of iron compounds on fire and explosion caused the cause of the accident in order to raise oil storage tank to prevent fire and explosion Study of different ambient temperature 15 ℃， 25 ℃， 50 ℃， 75 ℃ conditions， oxides of iron sulfide oxidation product of On the tank of sulfur compounds of iron sulfide formation and the oxidation product of burning oil for a theoretical analysis of the principle of sulfur oxidation of iron compounds in the dynamic changes of temperature and iron sulfur compounds the impact of certain factors oxidation system Experimental study has also examined in depth， combined with storage and transportation of oil processing and the actual situation in the process of influencing factors on the oxidation rate of the analysis and discussion， drawing in different curing conditionsTemperature curve of the product of Theoretically explained by the oxidation of sulfur compounds exothermic iron and fire and explosion caused the cause of the accident， and according to the experimental data and oxidation temperature curve of economic and effective preventive
