Abstract

Abstract: In order to explore development characteristics, HRR and fire hazard of oil pool fire in low pressure environment, n-heptane and aviation kerosene combustion experiments for oil pool of different diameters were carried out based on full-scale low-pressure HRR test platform. Characteristic parameters of oil pool fire were measured, including heat flux density, HRR and gas concentration. Then, effects of pool diameter on these parameters were analyzed. The results show that when distance between heat flow meter and oil pool is constant, heat flux density increases with increasing diameter, but decreases with increase of distance when the diameter is constant. Combustion heat of n-heptane is greater than aviation kerosene as the diameter is 10-20 cm while that of the latter is greater when it is more than 30 cm. Moreover, combustion of n-heptane produces more CO₂ than the other and burns more fully at the same time.

Key words: low pressure environment, oil pool fire, heat flux density, heat release rate(HRR), gas concentration
