火灾影响下立式储罐失效行为分析
Analysis of Failure Behavior of Vertical Storage Tanks Under Fire Influence
摘要
Abstract
In order to study the failure behavior of ig-nited storage tanks,a multi physical field coupling method of fire dynamics heat transfer structural re-sponse was adopted to analyze the thermal radiation distribution,temperature distribution law and model of the wall of the ignited vertical storage tank,as well as the buckling failure behavior.The results showed that the vertical storage tank on fire first underwent buckling deformation at the upper part of the liquid surface.For a 5 000 m3/10 000 m3 gasoline and diesel vertical storage tank,the critical buckling tem-perature was between 300～500℃,and the buckling failure time was between 30～70 s;As the size of ver-tical storage tanks increased,the critical buckling temperature significantly decreased,and the buckling failure time also significantly decreased.Buckling led to uneven walls and uneven cooling of vertical storage tanks,making it difficult to extinguish fires.It was recommended to strengthen the cooling protection of the tank walls near the liquid level.关键词
