FLAME ARRESTORS ORIGIN

The origin of the flame arrestors or arrester goes back to the "Davy lamp" invented by Sir Humpry Davy in 1816 to offset the fuel gas which is produced in coal mines, explosive gases when mixed with air. This lamp had the flame covered by a wire mesh through which there passes the spark or flame, upon cooling through the mesh fuel gases. However, the limited heat dissipation power along with low mechanical strength limited the reliability of this solution in the industrial field. Although the flame arrester is constructed in multiple ways, the most popular and secure is one composed of sheets coarrugadas confined flat sheets to form a cylinder with hundreds of openings. If cause a flame, the gas would be cooled below the ignition point to pass through the baffles, passing through it with a low pressure drop.

INLINE FLAME ARRESTORS

This category includes devices in off position, for example, a flame front of flammable vapors located on the roof of the tank and ignited by lightning or a spark. Since the flame front will attempt to burn the effluent gases from the opening of the vent valves, the deposit will always remain protected with a flame arrestor for a possible flashback. These flame arresters are characterized by:

  • Their high mechanical strength to be able to withstand the collision of an explosion inrerna.
  • Long duration of flame resistance

INLINE DEFLAGRANTION FLAME ARRESTERS

This category flame arresters able to extinguish a flame front, confined in a pipe, which moves at a speed less than that of sound. So this equipment will support significant mechanical and thermal energies.

INLINE DETONATION FLAME ARRESTERS

This category flame arresters able to extinguish a flame front, confined in a gallery, which moves faster than the speed of sound, so having the character of a detonation. The mechanical and thermal energies in this case are more critical and must resist such stresses.

Download Flame Arresters in Aluminium

The flame arresters in aluminum are very cheap and light, and the range of flame arresters in stainless are ideal for the chemical industry and services in applications that require high corrosion resistance.

CERTIFICATIONS
All the flame arrestors are built under the EC Directive 94/9 (ATEX).
