Flame arrester tested according to DIN EN ISO 16852 as Inline Detonation Flame Arrester
Detonation = explosion in which the flame propagates at supersonic speed.
The detonation flame arrester prevents flame penetration during deflagration and stable detonation of explosive vapour-air or gas-air mixtures.
Detonation = Explosion in which the flame propagates at supersonic speed.
Deflagration = explosion in which the flame propagates at subsonic speed.
If explosive gas ignites in a container or in a pipe, a deflagration (explosion) is triggered. If a flame front runs through a pipe, the flame speed increases with the pipe length. Up to a certain pipe length / pipe inner diameter ratio, the flame propagates at subsonic speed. If this length is exceeded, the flame accelerates from subsonic to supersonic speed. In order to stop a flame from propagating at supersonic speed, flame arresters tested as inline detonation flame arresters are required.
The installation position of the inline detonation flame arrester is independent of the distance to the ignition source. Detonation flame arresters are also certified as deflagration flame arresters.
