FLAME ARRESTER
 
Flame Arrester approved to EN ISO 16852 as End of Line Deflagration Flame Arrester
Flame Arrester approved to EN ISO 16852 as End of Line Deflagration Flame Arrester
To avoid a flame propagation from outside (atmosphere) to inside of systems e. g. storage tanks, vessels or in process plants a flame arrester at end of vent line has to be installed. End of line deflagration flame arresters protect the impact of atmospheric deflagration and prevent flame transmission to protect equipment. These flame arresters are not tested for short time or endurance burning.

An in-line deflagration flame arrester prevents light-back at deflagration of potentially explosive vapour-air and/ or gas-air mixtures.
If a flame front propagates through a pipe, its speed will increase proportionally to the length of the pipe. If a pipe is shorter than 50 times (respectively 30 times for explosion group IIB and IIC) its internal pipe diameter, the flame will propagate at subsonic speed. In this case, securing the protected side by a deflagration flame arrester will be sufficient. If the pipe is longer than 50 times its internal diameter (valid for explosion group IIA, IIB1, IIB2, IIB3 respective 30 times for explosion group IIB and IIC) flame will propagate at supersonic speed that means in a detonation.
A deflagration flame arrester operates at a lower pressure drop than a detonation flame arrester and is not suitable for detonation.

Ribbon Coil
Ribbon Coil
Ribbon Coils are also named as metal foil elements, flame arrester elements, flame resistors, flame arresters, grates, flame traps, etc.
Under certain conditions one or more ribbon coils can quench a developing flame front. The flame is directed through small capillaries and cooled by contact with their metal surface. Capillary height depends on the requirements (explosion group) that need to be fulfilled and needs to be adapted accordingly. Therefore a ribbon coil is not an approved divice.
A ribbon coil could be a flame quenching device that is mounted into a flame arrester. Diameter sizing, the choice of material, the determination of capillary height and the number of ribbon coil elements depend on what they are used for. Hence the design of a ribbon coil can only be determined through individual consultation and advice. It is thus impossible for an individual ribbon coil to be ATEX certified.
