Effects of Irradiation Intensity and Oxygen Concentration on Fire Risk of Rocket Kerosene
For oxygen-enriched combustion fire scenarios in special places such as launch sites,fire propagation apparatus(FPA)was used to investigate the effects of irradiation intensity and oxygen concentration on the ignition time and the heat release rate of rocket kerosene.The results showed that,with the same initial volume of rocket kerosene,the higher the irradiation intensity,the shorter the ignition time and the higher the heat release rate.The peak heat release rate at the irradiation intensity of 30 kW/m2 is three times that at the irradiation intensity of 5 kW/m2.Oxygen concentration has a more significant effect on the heat release rate,and the peak heat release rate at an oxygen concentration of 60%can reach more than 6 times that in the air.Besides,the fire performance index and fire growth index are also calculated in this paper,which can provide reference for the risk assessment and control of fire and explosion of rocket kerosene in oxygen-rich environment.
