摘要

过氧化苯甲酰(BPO)的燃烧不同于一般固体燃料的燃烧,是一个自反应过程。目前对BPO的储存采用喷淋保护,但喷淋的效果尚不清楚。本文结合BPO、FDS的ARC数据,对水雾保护下过氧化苯的贮藏条件进行了模拟。在模拟结果的基础上,采用回归分析的方法对喷淋保护下的火灾堆垛温升进行了分析,得到了不同距离下的堆垛温升。研究发现,在喷水保护下,距离对温升的影响不大,但能显著延缓闪络的发生。

Simulation of Influence of Water Spray on Runaway Temperature Field of Benzo Peroxide Storage Heat
This The fire of benzoyl peroxide (BPO) is different from that of common solid fuels, which is a process of self-reaction. At present, the storage of BPO is protected by spraying, but the effect of spraying is unknown. This paper combined the ARC data of BPO, FDS was used to simulate the storage condition of benzo peroxide protected by water spray. Based on the simulation results, the temperature rise of fire stacking under spray protection was analyzed by regression, and the temperature rise of stacking at different distances was obtained. It was found that distance has little effect on temperature rise and can greatly delay flashover under water spray protection.
