End of Line Flame Arrester Approved for Endurance Burning and Atmospheric Explosion

Flammendurchschlagsicherung geprüft nach DIN EN ISO 16852 als Deflagrations- und dauerbrandsichere Endsicherung
Flame Arrester approved to EN ISO 16852 as End of line deflagration flame arrester for Endurance Burning

Flame Arrester approved to EN ISO 16852 as End of line deflagration flame arrester for Endurance Burning

Deflagration = Explosion propagating at subsonic velocity

Endurance Burning = Steady burning of a flame stabilized at or close to the flame arrester element

End of line deflagration flame arrester installed at end of vent pipe prevents light-back at deflagration of potentially explosive vapour-air or gas-air mixtures from outside (atmospheric conditions) to the protected side (e. g. storage tank)  also in case of endurance burning.

Please contact us if you need flame arresters for storage or transport of alcohol, e. g. alcohol or alcohol petrol blends like HBEF, superethanol and ethanol diesel blends like Diesohol.

To prevent unnecessary heating up of the flame arrester the rain cover removes automatically after a short time.

End of Line Deflagration Flame Arrester approved for Endurance Burning : Explanation

Flame Arrester that prevents flame transmission during and after endurance burning.

Deflagration = Explosion propagating at subsonic velocity

Endurance Burning = Steady burning of a flame stabilized at, or close to, the flame arrester element.

In case of overpressure in storage tank, gas, vapor or aerosol escapes trough vent to atmosphere. In case gas, vapor or aerosol mixture is ignitable then a flame will burn on the top of the vent as long (endurance burning) as the pressure in storage tank is higher than atmospheric pressure. As soon gas flow ends or the storage tank pressure is nearly atmospheric, then the flame will propagate in direction to the storage tank. End of line deflagration flame arrester tested for endurance burning prevents the flame from striking the storage tank when the gas flow decreases, despite the heating caused by the fire.

To prevent unnecessary heating up of the flame arrester the rain cover removes automatically after a short time. After the flame will burn as long as the overpressure in the system supplies gas.

Please consider:  End of line deflagration flame arresters approved for endurance burning of alcohols and non-pure hydrocarbons require a separate test.
