摘　　要：The risk and thermal safety characteristics of GX kerosene,HX kerosene and WX kerosene are studied.Firstly,the explosion lower limits of three kinds of kerosene steams are tested by using the self-made explosion limit measuring system.Then differential scanning calorimeter(DSC)is employed to perform linear heating experiment on kerosene to analyze its thermal decomposition characteristics.The pyrolysis kinetic parameters of three kinds of kerosene are calculated based on the thermal dynamic methods.The experimental results show that the flash point and lower explosion limit of GX kerosene are relatively low.The DSC test shows that the lowest initial decomposition temperature of HX kerosene is 116.5℃.According to pyrolysis kinetics calculation,the T_(D24) and apparent activation energy of HX kerosene are the minimum.ARC test shows that GX kerosene has the worst thermal stability under the adiabatic condition.The high temperature stabilities of the three kinds of kerosene all meet the requirements.On the whole,GX kerosene has the highest hazard,and HX kerosene has the lowest thermal safety.The accumulation of heat should be prevented during the storage and transportation of kerosene.This study provides the crucial safety characteristics data of coal-based aerospace kerosene-based,and provides technical support for engine reliability growth and performance improvement.
