Understanding Flame Arrestors: From Function to Application

Flame arrestors are important safety devices in industries that handle flammable gases, liquids or vapours. They are used in pipes and vents to prevent or limit the spread of flames and possible explosions. The main function of a flame arrestor is to stop the spread of fire by absorbing and dissipating the heat of the flame or extinguishing it completely. They are designed to allow the flow of gases or liquids under normal conditions. However, in the event of a flame or explosion, they restrict the flow, thereby preventing the further spread of fire.

Applications of Flame Arrestors

In the oil and gas, petrochemical, chemical and pharmaceutical industries, flame arrestors are essential for safe operation. They are usually installed at critical points in the process where there is a risk of fire or explosion, such as:

• Storage tanks
• Mixing vessels
• Pipelines

Types of Flame Arrestors

Flame arrestors come in various shapes and sizes, depending on the application and the type of gas or liquid being processed. The most common types include deflagration barriers, detonation barriers, and fire extinguishers.

• Deflagration barriers are used in low-pressure applications and are designed to extinguish flames by cooling.
• Detonation barriers, on the other hand, are used in high-pressure applications and are designed to cushion the shock wave of a sudden explosion.
• Fire extinguishers are typically used in small applications and create swirling motions to quell the flame.

Important Parameters and Selection

An important parameter of a flame arrestor is its maximum allowable gap (MAG). MAG is the maximum distance between the flame arrestors that prevents the spread of flame or explosion. The MAG value is determined by the type of gas or liquid and the expected flow rate. Careful selection of the appropriate flame arrestor for a specific application is essential to ensure that it will effectively prevent fires and explosions.

Conclusion

In summary, flame arrestors are essential safety devices in industries where there is a risk of fire or explosion. They operate by controlling the spread of flame and are designed to operate at high temperatures and pressures. Correct selection and installation of flame arrestors is critical to maintaining safe work in these industries and plays a significant role in preventing accidents and protecting personnel and equipment.
