| 摘 要： | 天然气管道发生泄漏时,大约90%的气体产生燃烧并形成火球,遇火源即发生危害性非常大的火球爆炸事故。本文针对城市天然气管道泄漏事故,综合考虑天然气泄漏后可能发生的火球燃烧和爆炸,利用爆炸冲击波和火球热辐射模型对天然气管道(完全破裂)在发生泄漏时发生火球爆炸进行计算,结果表明:2分钟内泄漏天然气云团超压爆炸的死亡半径和热辐射的火球半径分别高达39.44m和92.93m。因此,通过计算天然气泄漏火球事故爆炸和热辐射范围,对天然气火球爆炸事故预防与应急救援具有一定的意义。 |

| Abstract: | About 90% natrual gas will be burned and formed the fireball when the natrual gas pipeline leaked,and it will bring an extremely hazardous fireball explosion accident.In this paper,a method of shock wave assessment and evaluation of fireball thermal radiation were uesd for fireball explosion because of leakage of natrual gas pipeline（full rupture） considering the fireball combution and explosion for the natrual gas pipeline leakage accident.The results indicated that the death radius of explosion overpressure and fireball radius of fireball combution about natrual gas cloud were up to 39.44m and 92.93m respectively in two minutes.So the computation of natrual gas firebaoll combution and explosion radius can provide the available foundation for natrual gas fireball explosion prevention and it has certain significance to emergency rescue of natural gas fireball accident. |
