由于高压氢气释放到空气中而引起的自燃过程是已知的现象。加压氢气突然膨胀进入充满环境空气的管道，可能导致自燃并产生喷射火。本文介绍了可见火焰传播和压力测量的实验研究结果，在4毫米延长管的长度可达1米的散装容器的爆破片连接。在这项研究中使用透明玻璃管的视觉观察和冲击波压力传感器。讨论了延长管长度对自燃后稳定射流火发展的影响。版权所有（C）2014，氢能出版物有限责任公司。由爱思唯尔有限公司出版。保留所有权利。
Spontaneous ignition processes due to high pressure hydrogen releases into air are known phenomena. The sudden expansion of pressurized hydrogen into a pipe, filled with ambient air, can lead to a spontaneous ignition with a jet fire. This paper presents results of an experimental investigation of the visible flame propagation and pressure measurements in 4 mm extension tubes of up to 1 m length attached to a bulk vessel by a rupture disc. Transparent glass tubes for visual observation and shock wave pressure sensors are used in this study. The effect of the extension tube length on the development of a stable jet fire after a spontaneous ignition is discussed. Copyright (C) 2014, Hydrogen Energy Publications, LLC.
