Inline Detonation Flame Arrester: Concentric

Deto Rohrsicherung
Inline Detonation Flame Arrester: Concentric

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.

Inline Detonation Flame Arrester / Explanation

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.

Inline Detonation Flame Arrester: Eccentric

Eccentric type inline detonation flame arresters in horizontal installation are preventing condensate accumulation inside of the arrester.

Inline Detonation Flame Arrester: Short Time Burning

Inline detonation flame arrester approved for stabilized burning for specified time. For detection of a stabilized flame a PT100 temperature sensor mounted on the unprotected side is necessary! When a stabilized flame is detected an action within 30 seconds has to be carried out which ensures a safe quenching of the flame. (E.g. stopping the gas flow)

Inline Detonation Flame Arrester: Endurance Burning

Inline detonation flame arrester approved for stabilized burning for unlimited time.

Inline Detonation Flame Arrester: Elbow Type (90°)

Inline detonation flame arrester as elbow type allow an easy access for cleaning the flame arrestor elements.
