摘要: 为研究高高原机场特定环境中正庚烷油池火燃烧特性,考虑火灾受空气氧分压等因素影响,在康定高高原机场实验室利用ISO9705燃烧系统开展等效火灾油池的燃烧试验,重点分析热释放速率、燃烧速率、温度场分布和火焰辐射热通量等特性参数的变化规律。结果表明:燃烧速率方面,油池尺寸和单位面积燃烧速率近似呈线性变化;火场温度方面,受大气压力和空气密度影响,油池轴线最高温度较常压低,温升与经典羽流温升理论存在偏差;热辐射通量方面,通过曲线拟合方法得到油池尺寸与热辐射通量的关系式。

Abstract: To analyze the high plateau airport pool fire combustion characteristics affected by the low air pressure, such as flame temperature, mass burning rate and radiation flux, experiments were conducted in the Kangding High Platea Airport Laboratory with by using an ISO9705 combustion system. Heat release rate, burning rate and flame temperature field distribution and flame radiation heat flux were recorded and analyzed. The relationship between oil pool size and mass burning rate was deduced, and it was found that the mass burning varies linearly with oil pool size. The flame temperature was found that the classical theory cannot correctly predict the airport plume temperature rise for the influence of low pressure and low oxygen concentration. By the curve fitting method, the relationship between the oil pool size and the heat radiation flux was also obtained.

Key words: high plateau, oil pool fire, burning rate, plume temperature, thermal radiation
