Boiling liquid expanding vapor explosion - Wikipedia

A boiling liquid expanding vapor explosion (BLEVE, / b l v i / BLEV-ee) is an explosion caused by the rupture of a vessel containing a pressurized liquid that has reached temperatures above its boiling point. Because the boiling point of a liquid rises with pressure, the contents of the pressurized vessel can remain liquid so long as the vessel is intact.Power Transformers and Environmental Protection , burundi transformer tank fire volumePower Transformers and Environmental Protection. , burundi transformer tank fire volume infrastructure ï INTRODUCTION Transformer explosions and successive fires are caused by internal breakdown in transformer tank.
