摘　　要：主要针对液化石油气储罐受热侵袭时出现的分层现象进行了实验研究。通过自行设计的液化石油气储罐加热系统,便于分析热流密度对分层升压过程的影响。实验数据表明,随着热流密度的增加,升压速度也将增大。同时,在液化石油气中,不同位置上的温度变化也是不同的。越接近上部,温度越高,温度增加也越快。实验结果说明,受热时液化石油气中存在着热分层现象,它影响着液化石油气的温度分布和升压过程。The experimental bench is set up to study the thermal response in the LPG(liquefied petroleum gas)vessel when heated by fireThe heating system is reasonably designed to simulate the situation where the vessel is heated isothermallyThat will make it easy to analyze how heat flux affects the processes of pressurization and stratification in LPG vesselThe result shows that pressure rises faster if the heat flux increasesThe temperature at different height from the bottom of vessel also rises at different velocityThe temperature at higher level is greater and varies more greatlyThose prove that there is the stratification layer within LPG and it has effect on the temperature and pressurization
