摘要： 为了研究野外组合式软体油罐在不同辐射强度下的燃烧特性，通过锥形量热仪对软体油罐样本进行燃烧实验，选用25,35,50 kW/m2三种典型的热辐射强度进行研究，得到点燃时间、热释放速率、比消光面积、烟气生成速率、火焰形态等参数的变化规律。结果发现：热辐射强度为50 kW/m2时，点燃时间分别为25,35 kW/m2时的38%和53%；最大热释放速率分别为25,35 kW/m2时的1.4倍和1.7倍，而达到峰值所需时间分别缩短15%和40%；燃烧的最大烟气生成速率分别为25,35 kW/m2时的1.4和1.8倍；燃烧后剩余的炭层质量分别减少1/3和1/2。

Abstract: In order to study the combustion characteristics of field combined soft oil tank under different radiation intensities, the combustion experiments of soft oil tank samples were carried out by cone calorimeter. Three typical heat radiation intensities of 25, 35 kW/m2 and 50 kW/m2 were selected, and the data of ignition time, heat release rate, specific extinction area, smoke generation rate and flame shape were obtained. The results show that when the thermal radiation intensity is 50 kW/m2, the ignition time is 38% and 53% that of 25 and 35 kW/m2, respectively; The maximum heat release rate is 1.4 times and 1.7 times that of 25 and 35 kW/m2 respectively, and the time to reach the peak is reduced by 15% and 40% respectively; The maximum flue gas generation rate of combustion is 1.4 and 1.8 times that of 25 and 35 kW/m2 respectively; After combustion, the mass of remaining carbon layer is reduced by 1/3 and 1/2 respectively.
