摘要/Abstract

摘要： 针对燃气站场混氢输送的安全性问题，基于FLACS软件进行掺氢燃气站场事故情景构建，重点针对气体泄漏、气云爆炸以及喷射火3种典型事故展开后果评估。结果发现：泄漏中后期，气云发展规模增大，气云边界的弥散速度与泄漏速度将达到动态平衡。掺氢比例增加在一定程度上缩短了天然气的爆炸区域，并导致总体泄漏气云量下降。当掺氢比为20%时，气云爆炸产生的超压值最高，危险系数最高。氢气的体积能量较小，掺氢行为会降低气体的能量含量。掺氢比例增加后，喷射火灾的风险范围有所减小。

Abstract: Abstract: Aiming at the safety of mixed hydrogen transportation in gas stations, the accident scenario of hydrogen doped gas stations was constructed based on FLACS software. The consequence assessment was carried out on three typical accidents: gas leakage, gas cloud explosion and jet fire. The results show that in the middle and late stage of leakage, the development scale of gas cloud increases, and the dispersion velocity and leakage velocity of gas cloud boundary will reach a dynamic balance. The increase of hydrogen doping ratio shortens the explosion area of natural gas to a certain extent, and leads to the decrease of overall leakage cloud. When the hydrogen doping ratio is 20%, the overpressure value and risk coefficient produced by gas cloud explosion are the highest. The volume energy of hydrogen is small, and the hydrogen doping behavior will reduce the energy content of the gas. With the increase of hydrogen ratio, the risk range of jet fire decreases.
