【摘要】：为了分析悬挂链式辐照室的火灾危险性,采用实验测定得出室内典型辐照物品的点着温度,通过设置3组火灾场景模拟得到卡源故障下各火灾场景辐照室内温度变化曲线。结果表明:各火灾场景卡源初期1 h,温度上升速度较快。随着时间的增长,室内温度不断上升,但上升速率逐渐放缓。在火灾场景A,B,C等3组条件下卡源故障分别发生9,4,2.4 d后,室内局部温度能达到210℃,室内辐照物品有可能被引燃。
[Abstract]:In order to analyze the fire risk of hanging chain irradiator, the ignition temperature of typical irradiated items in the room was measured by experiments, and the indoor temperature variation curves of each fire scene under kaysource fault were obtained by setting up three groups of fire scenes to simulate the fire scene. The results show that the temperature rises rapidly at the beginning of 1 hour in each fire scene. With the increase of time, indoor temperature continues to rise, but the rate of rise gradually slows down. In the fire scene A, B, C and other three groups of conditions, the card source failure occurred 9, 4, 2.4 days later, the indoor local temperature can reach 210 鈩，
