Understanding Flame Arrestors: How They Prevent System Ignition

What is a Flame Arrestor?

A flame arrestor is a mechanical device consisting of a screen or series of perforated metal plates installed in a pipe or vent line. Its job is to allow gases or liquids to pass through, but prevent flames from entering the system.

A flame arrestor can be installed in a variety of locations, including:

• Pipes
• Tanks
• Vents
• Storage containers

These installations protect against potential hazards from flammable gases and liquids.

How does a flame arrestor prevent a system from igniting?

Flame arrestors work by extinguishing flames. As a flame spreads through a system, it creates a fast flame front that transfers heat and energy. The flame front hits a flame barrier, which interrupts and extinguishes it.

Perforated metal plates or screens in a flame arrestor create narrow channels that divide the flame front into smaller, cooler flames, reducing their speed and extinguishing the flame.

Another way a flame arrestor prevents a system from igniting is by reducing the temperature of the flame. The metal plates or screens absorb the heat from the flame and lower its temperature below its ignition point. This prevents it from reaching other parts of the system, which could cause a fire or explosion.

In addition, flame arrestors also prevent flashback, which is the return of flames into the system. They prevent flashback by creating a gap between the flame and the ignition source, thus preventing the flame from coming into contact with the fuel and causing an explosion.

Conclusion

Flame arrestors are important safety devices used in various industries to prevent fires and explosions. They work by extinguishing the flame and lowering its temperature. This prevents the substance from spreading to other parts of the system and causing ignition. Flame arrestors are a key element in the safety of workers and equipment.
