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.ON THE SPRINKLER TANK SIZE AND FAST RESPONSE International Journal on Engineering Performance-Based Fire Codes, Volume 2, Number 4, p.124-126, 2000 124 ON THE SPRINKLER TANK SIZE AND FAST RESPONSE SPRINKLER HEADS W.K.
