Inline Detonation Flame Arrester approved to EN ISO 16852 in Eccentric Design
Deflagration = Explosion propagating at subsonic velocity
Detonation = Explosion propagating at supersonic velocity and characterized by a shock wave
Inline detonation flame arrester prevents a flame propagation to the protected side in case of deflagration and detonation of explosive vapor-air or gas-air mixtures.
Inline Detonation Flame Arrester – Eccentric: Explanation
Deflagration = Explosion propagating at subsonic velocity
Detonation = Explosion propagating at supersonic velocity and characterized by a shock wave
Inline detonation flame arresters are fitted with two pipe connections, one on each side of the flame arrester. Inline detonation flame arresters are designed to prevent the transmission of a detonation (explosion propagate at supersonic velocity).
Ignited explosive gas mixture will propagate through the pipe in direction to e.g. storage tank. With pipe length the speed of flame will increase. Up to a certain pipe length / pipe inside diameter ratio, the flame propagate changes from subsonic speed (Deflagration) to supersonic speed (Detonation).
Compared to the concentric design, the eccentric design allows condensate to drain off and allows easy installation in places where the installation is close to the floor or a wall.
