Classification of Explosion

Difference between fire explosion is the rate of release of energy in fire it is a storage it are explosion high rate and sudden released.

  1. Physical energy
  2. Chemical energy
  3. Nuclear energy

What Is Explosion ?

Explosion is a result of rapid combustion with sudden, violent change operation involving the liberation and explosion help large volume of gas.

Classification Of Explosion :

  1. Dust explosion
  2. Deflagration
  3. Detonation
  4. Confirm and unconform more vapour cloud explosion ( VCE )
  5. Boiling liquid Expording Vapour explosion ( BLEVE )

Dust Explosion

  • Explosion ➙ Large Volume of gas, gases will be Harmful or not.
  • Blast ➙ Explosion
  • Implesion ➙ Happens at the same place like building collapse.

Difference Between Explosion and Implesion

➙ Dust explosion is they rapid combustion of fine particles suspend in air within the enclose location.

➙ Does explosion can occur where any dispressed powder combustible metals is present in high in a concentration in the atmosphere.

Dust Pentagon

Dust Pentagon

➙ Disper or Dust mens dust particles are suspended in Air.

➙ Dust is inan and closed limited space this restrics allowed to pressure build up increasing likely hood explosion.

Dust Explosion

Vapour Cloud Explosion (VCE)

Leakage of light petroleum products like petrol, CNG, LPG, hydrogen, naptha, methane, flammable vapours, next with air and ignited and blast may happen with high pressure.

Vapour cloud explosion : There are two Types

  1. CVCE (Confine vapour cloud explosion)
  2. UVCE ( open areas fires )

Example : Reactor, vessel, pipe, Building, pit.
