Bleves (Boiling Liquid Expanding Vapor Explosions). 

BLEVE (Boiling Liquid Expanding Vapor Explosion) A blast resulting from the sudden release and nearly instantaneous vaporization of a liquid under greater-than-atmospheric pressure at a temperature above its atmospheric boiling point. The material may be flammable or nonflammable. A BLEVE is often accompanied by a fireball if the contained liquid is flammable and its release results from vessel failure. 

A physical explosion, for example, a boiler explosion, a pressure vessel failure, or a BLEVE (Boiling Liquid Expanding Vapor Explosion), is not necessarily caused by a chemical reaction. Chemical explosions are characterized as detonations, deflagrations, and thermal explosions. In the case of a detonation or deflagration (e.g., explosive burning), a reaction front is present that proceeds through the material. A detonation proceeds by a shock wave with a velocity exceeding the speed of sound in the unreacted material. A... 

BLEVE (Boiling Liquid Expanding Vapor Explosion) See Boilover the same phenomenon may occur in a pressurized container, resulting in an explosion or bursting of the tank or vessel in which a fire is occurring. The term is almost exclusively used to describe a disastrous effect from a crude oil fire. 

The superheat limit was first proposed in the late 1970s as a possible mechanism for explaining catastrophic vessel failures. Reid (1979), Jones (1985), Martinsen et al. (1986), Davenport (1988), and Dunn (1988) suggest that BLEVEs (Boiling Liquid Expanding Vapor Explosions) are superheat explosions and therefore are easily predicted by assessing the superheat limit for any pressurized liquid material.

A BLEVE (Boiling Liquid Expanding Vapor Explosion) is a special type of explosion. It can occur if a tank or vessel containing a liquid is subject to external fire. The heat causes the liquid in the...

BLEVEs (Boiling Liquid Expanding Vapor Explosions) A pressurized tank of VCM or associated piping exposed to an external fire may fail due to metallurgical weakening. Such failure may result in a catastrophic tank failure, a fireball and the potential for rocketing fragments. Relief valve overpressure protection will not prevent a BLEVE.
