endurance burning
Endurance burning
Stabilized burning for an unlimited time.
. These devices are made to stop flames from spreading into process systems when there are outside ignition sources. Installed at the termination point of vent lines or pipelines, they act as a critical safety barrier where flammable gases or vapors are released to the atmosphere.
These devices are particularly relevant in storage tank venting, emission control systems, and process installations where exposure to atmospheric ignition risks cannot be fully eliminated. By stopping flame transmission at the boundary between the system and the environment, they help maintain plant integrity and reduce the risk of escalation.

Lorem Ipsum Working principle of Flame Arresters
Lorem Ipsum The FLAMEFILTER® is made of wound metal strips and forms an effective band arrester. This flame- quenching Quenching Cooling of a fluid by mixing it with another fluid of a lower temperature. principle is applied in PROTEGO® end-of-line Flame Arresters and in-line Flame Arresters.
When a mixture ignites in a gap, the flame spreads towards the unburned mixture. The volume expansion of the burned mixture pre-compresses the unburned mixture and accelerates the flame propagation.
Lorem Ipsum Heat dissipation to the large surface of the gap lowers the temperature below the ignition temperature Ignition temperature Lowest temperature (of a hot surface) at which ignition of a flammable gas or vapor in a mixture with air or air/inert gas occurs under specified test conditions. , thus extinguishing the flame.
The gap width and gap length determine the extinguishing effectiveness of the Flame Arrester.
A narrower and longer gap extinguishes the flame more effectively, while a wider and shorter gap reduces the pressure loss. Experiments can determine the optimum solution between the two conditions.
The PROTEGO® devices are working to our utmost satisfaction. PROTEGO®—who, with their technical expertise, supported in reducing the overall life cycle cost of the Detonation Detonation Explosion propagating at supersonic velocity and characterized by a shock wave (EN 1127-1: 1997). Flame Arresters installed at our plant by installing flame arresters Flame Arresters A flame arrester, deflagration arrester, or flame trap is a device or form of construction that will allow free passage of a gas or gaseous mixture but will interrupt or prevent the passage of flame. , which are easy to clean and maintenance-friendly.
