THORNTON模型及H&S法计算天然气管道喷射火灾事故后果

THORNTONmodelling and the H&S(Hustad&Sonju)method for calculating the consequences of gas pipeline jet fire accidents

天然气作为重要的清洁能源被广泛的使用于工业生产活动中,管道运输是天然气资源输送的主要方式。由于种种原因当管道失效后,伴随天然气扩散可能发生喷射火灾、蒸汽云爆炸、闪火火灾等严重事故,其中喷射火灾最为常见。本文利用THORNTON模型及H&S(Hustad & Sonju)法模拟计算天然气管道泄漏后发生喷射火灾的事故影响范围,为天燃气管道设计与安全运行提供参考。

As an important clean energy source,natural gas is widely used in industrial production activities,and pipeline transportation is themain way to deliver natural gas resources.Due to various reasons,when the pipeline fails,serious accidents such as jetfires,vapor cloud explosions,flashfires,etc.may occur along with the spread of natural gas,of which jetfires are themost common.In this paper,the THORNTONmodel and the H&S(Hustad&Sonju)method are used to simulate and calculate the accidental impact range of jetfires after natural gas pipeline leakage,so as to provide reference for the design and safe operation of natural gas pipelines.
