摘要

摘要: 沸騰液體膨脹蒸氣爆炸(boiling liquid expanding vapor explosion,BLEVE)是過熱液體整體沸騰迅速膨脹引發的爆作.液化氣罐在儲運中時有BLEVE在發生.基于英國健康與安全署的關于液化氣罐在火焰包圍環境下的實驗結果,分析了儲罐受熱后其內部壓力、罐壁溫度變化及儲罐介質排放等一系列熱物理過程及各相關因變量之間的相互關系.據此介紹了可以模擬儲罐受熱引發BLEVE現象的壓力液化氣仿真軟件PLGS99的物理模型與數學模型,并在此基礎上詳舉實例討論了儲罐受熱引發BLEVE爆炸的機理.

Abstract: The boiling liquid expanding vapor explosion (BLEVE) is an explosion caused by bulk boiling and rapid expanding of superheated liquid. It often happens in liquefied petroleum gas (LPG) tanks during stationary and transportation storage. Based on experimental results from the Health and Safety Executive of England on LPG tanks under pool and jet fires, the authors investigated the thermo-physical processes including internal pressure change, wall temperature change and LPG mass release in LPG tanks as well as the relations among the dependent variables. Physical and mathematical models were presented in PLGS99 (pressure liquefied gas simulation) software to simulate the temperature and pressure responses of LPG tanks. The predictions were validated by experimental data and the explosion mechanism of LPG tanks caused by BLEVE was analyzed.
