Combustion Research Associates manufactures many safety devices for gas applications. Flame arrester is an important member of safety equipments family.

Flame arrester is used for preventing flash back in the process lines, fuel lines, storage tanks having potential risk of accidental flame flash back.

Combustion Research Associates manufactures INLINE and END OF LINE flame deflagration arresters and IN LINE detonation arrestors for all general, specific and customized requirement of the Industry.

Operation Type :
Detonation arrestors are also available for the critical applications of detonation.

Construction :
The flame arrestors consists of housing, flame element and connections and optional accessories ( thermal shut off value, drains valve, differential pressure alarm system etc).



Materials :

HOUSING	LOW COPPER ALUMINUM, CAST IRON, STAINLESS STEEL, - Other materials and coatings available on request.
FLAME ELEMENT	SS316, SS304, Aluminum, Copper.
Sizes	Sizes are available from ¼ to 12 ( 6mm to 300 mm) Other/Higher sizes available on request
Pressure Rating	Standard 5- 10 bar High-pressure ratings available on request.

Flame arresters block the propagation of flame by quenching the flame passing through it. The heat of flame is absorbed by the flame element where very high surface area is provided for immediate heat transfer.

It has no moving parts and the custom designed flame element gives the necessary protection from flame flash back. Where as the flame propagation is blocked through the flame elements, the gases can pass through them easily having minimum pressure drop. This is ensured by having large flow area available to gases in the flame bank.
TYPE / NOMENCLATURE OF FLAME ARESTORS

1. Deflagration Arrestors
The deflagration arrestors are generally used with group I gases. These gases do not Have the detonation characteristics.

2. Detonation Arrester
If the gases belong to II A, IIB and IIC group with high detonation characteristics and flame front traveling at speed exceeding Mach 1 (supersonic) then the detonation arresters are advised. Detonation arrestors are also advised in pipelines with high working temperature of the medium.

3. In Line Flame Arrester
These flame arrestors are used in the pipe line and manufactured for flame deflagration and Detonation

4. End Of Line Flame Arrestors
They are normally used on the storage tanks or for venting the combustible gases into the atmosphere. The protection of these flame arrestors is generally for Deflagration only.
