Understanding Flame Cells and How They Limit Flame Speed with Flame Arrestors

Flame arrestors, also called flame arrestors, are important safety devices used in various industries to prevent the spread of fires and explosions. They are installed in piping systems and equipment that transport flammable gases and vapors. They slow the flame, thus reducing the risk of explosion and fire.

How Flame Arrestors Work

Flame arrestors are designed to interrupt the flow of flames and prevent their spread in the piping system. They consist of a metal or mesh screen with precisely shaped openings that block the flames. The screen acts as a barrier, forcing the flames to flow through small openings and dividing them into smaller flames that lose their energy and slow down.

The size and shape of the flame arrestor's openings are crucial in reducing the flame's speed. The smaller the openings, the more effectively the arrestor slows the flames. Smaller openings create more resistance, causing the flames to split into smaller flames, lose their energy, and slow down. The shape of the openings also helps slow the flames. The zigzag and twisted arrangement of the openings creates turbulence that further disrupts the flow of the flames and reduces their speed.

Materials and Design

The material used to construct flame cells also plays an important role in their effectiveness in slowing the flames. The most commonly used materials for flame cells are metals such as stainless steel or aluminum, which have high melting points and can withstand high temperatures. The mesh design also allows for a large surface area, maximizing contact between the flames and the metal, resulting in better heat dissipation and flame deceleration.

Importance of Flame Arrestors

In short, flame cells are important safety devices that play a crucial role in preventing the spread of fire and explosions. Their precise construction and design work together to slow the flame and reduce the risk of dangerous incidents. The use of flame cells is recommended in all industries where flammable gases and vapors are present, as they provide additional protection against potential fire hazards.
