'''Flameless Explosion Vent''' is a safe indoor venting solution for explosion protection of indoor processes in personnel areas. It uses a stainless steel mesh filter to quench vented explosions and arrest flames. | |||
==Features== | |||
*Ideal for small volume venting inside buildings. | |||
*Low cost installation and reconditioning after actuation. | |||
*Stand-alone, passive protection system. | |||
*Single integrated unit reduces the need for costly suppression systems. | |||
*Full compliance with NFPA and European requirements. | |||
==Operation Principles== | |||
Flameless Vent System was developed in response to a specific need, i.e. explosion venting inside buildings. Traditional explosion venting technologies require a safe venting area (usually outdoors), where there is no risk of secondary explosions or harm to personnel. Explosion vented plant has to be ducted out to a designated (external) safe area (usually within 3 to 6 metres). The only alternative was to strengthen vessels to withstand greater explosion pressures and/or to install relatively expensive explosion suppression systems. | |||
The design allows venting of explosions without the attendant risks of an external fireball and without the use of vent ducts. It is essentially a flame-arrester comprising a porous, heat-absorbing surface in the form of a pipe. The vented explosion enters the pipe, the gases are cooled as they pass through the porous surface, dust is filtered out and the flame is quenched. The internal surface-area of the is designed so that the effective vent area is almost the same as if the vent itself was free. | |||
