A boiling liquid expanding vapor explosion is an explosion caused by the rupture of a vessel containing a pressurized liquid that is or has reached a temperature sufficiently higher than its boiling point at atmospheric pressure. Because the boiling point of a liquid rises with pressure, the contents of the pressurized vessel can remain a liquid as long as the vessel is intact. If the vessel''s integri

6 FAQs about [Steam storage tank explosion]
What happens if a storage tank explodes?
As the distance from the burst center increased, the damage probability of each target storage tank decreased with the shock wave overpressure, and the domino effect probability value for the T2, T4, and T5 storage tanks reached 100%. The first explosion would cause catastrophic damage to the target equipment in the near field area.
How do explosion sources affect the failure of a storage tank?
The failure of the target storage tank in the middle and far field is greatly affected by two or more explosion sources. The maximum superimposed shock wave propagates along the line direction of the source of the explosion. With the increase of explosion sources, the overpressure of storage tank increases and explosion interval time decreases.
Why did a gas tank explode?
There was a minor explosion, then a strong hiss, and then a major explosion, suggesting that an initial crack had formed by thermal stress at a very hot location on the LNG tank wall which was arrested in a cooler and stronger zone, followed by a discharge (probably two-phase flow which created the hiss).
What is boiling liquid expanding vapour explosion?
Definition of BLEVE The Centre for Chemical Process Safety has defined boiling liquid expanding vapour explosion (BLEVE) as ‘a sudden release of a large mass of pressurized superheated liquid to the atmosphere’.
What is the law of initial explosion impact in LPG tank area?
The law of initial explosion impact in the LPG tank area was analyzed. The ANSYS numerical model of the LPG tank explosion was established based on the calculation of the tank shock wave overpressure and the target tank failure.
What happens if a container explodes?
The increase in volume caused by the instantaneously vaporizing mass of liquid is enormous, which, added to the expansion of the pre-existing compressed vapour, generates a strong pressure wave. The resulting massive explosion can often shatter the container into several pieces, and propel the pieces to considerable distances.
