Comparative Study on Combustion and Explosion Characteristics of High Flash Point Jet Fuel

Abstract Jet fuel is a kind of hazardous chemical and it can easily result in combustion or explosion accidents in the process of production, use, storage, transportation and other aspects, so its safety issues are essential and urgent. Explosion performance testing device and combustion performance testing device have been used to study the combustion and explosion characteristics of high flash point jet fuel and No.3 jet fuel. The results show that the explosion pressure and explosion pressure rise rate have a rising trend with the spray pressure increases. The ignition time of high flash point jet fuel was later than that of No.3 jet fuel, showing that high flash point jet fuel is more safety than No.3 jet fuel. The obtained combustion and explosion parameters of the two kinds of jet fuel from the experiments can be used to evaluate their safety quantitatively.
