摘要

本文讨论了气体爆炸的超压和应用细水雾抑爆的性能。根据实验结果,开口面积越大,压力越难积聚,导致气体爆炸的超压越低。当开口在高空气速度环境下打开时,夹带的空气量更大。因此,爆炸的发生时间比在低空气速度下更短。尽管细水雾喷嘴安装在外壳外,但无论使用多少细水雾,仍发生丙烷气体爆炸,未能抑制爆炸。然而,安装在外壳内的细水雾喷嘴提供了足够量的细水雾,可以冲洗部分丙烷,导致燃料浓度降至爆炸下限以下,阻碍了爆炸的发生。

Evaluation of propane explosion with applied water mist
This article discusses the overpressure of a gas explosion and the performance of applying water mist for explosion suppression. According to the experimental results, the larger the opening area, the more difficult it is for pressure to accumulate, resulting in lower overpressure of a gas explosion. When the opening was opened under a high air speed environment, the amount of entrained air was greater. Consequently, the occurrence time of the explosion was shorter than at a low air speed. Despite the water mist nozzle being installed outside the enclosure, a propane gas explosion still occurred regardless of the amount of water mist used, failing to suppress the explosion. However, the water mist nozzle installed inside the enclosure supplied an adequate amount of water mist that could wash a part of the propane, resulting in the fuel concentration dropping below the lower explosion limit, hindering the occurrence of an explosion.

期刊介绍: The Journal of Fire Sciences is a leading journal for the reporting of significant fundamental and applied research that brings understanding of fire chemistry and fire physics to fire safety. Its content is aimed toward the prevention and mitigation of the adverse effects of fires involving combustible materials, as well as development of new tools to better address fire safety needs. The Journal of Fire Sciences covers experimental or theoretical studies of fire initiation and growth, flame retardant chemistry, fire physics relative to material behavior, fire containment, fire threat to people and the environment and fire safety engineering. This journal is a member of the Committee on Publication Ethics (COPE).
