输气干线放空系统火灾爆炸事故后果评估

摘要

首先采用FLUENT软件对放空气体扩散进行定量计算，确定火灾爆炸的中心，然后采用挪威船级社PHAST软件对放空气体可能产生的火灾爆炸影响范围进行定量计算和影响分析，最终确定不同放空量和风速下地面上火球事故爆炸和热辐射范围，对放空系统安全设计和应急救援具有一定的意义。%Making use of FLUENT software to quantitatively calculate the venting gas diffusion and to deter-mine fire explosion’ s center was implemented, including applying PHAST software to quantitatively calculate and analyze potential fire explosion’ s scope of influence so that the heat radiation above the ground incurred by the explosion accident at different venting amount and wind speeds can be determined. This has certain sig-nificance for venting system security design and emergency rescue.
