Deflagration Suppression Systems

Deflagration is a combustion that propagates through a gas or along the surface of an explosive at a rapid rate driven by the transfer of heat. FENWAL Protection Systems are designed to detect and contain explosions from spreading to interconnected equipment and other locations within a processing facility.

There are two approaches to handling deflagration from spreading down a pipeline damaging equipment.

The first is to use a chemical suppression system. In this system, the pressure wave is detected by a sensitive press sensor that is measured by a control unit which instructs a chemical suppression agent to be discharged into the pipeline mitigating the passage of the flame and burning material further down the pipeline.

The second is to use a mechanical isolation system. In this system, the pressure wave is detected by a sensitive press sensor that is measured by a control unit which instructs a high speed knife valve to close forming a barrier, stopping the flame and burning material from traveling further down the pipeline.

Both of these approaches to eliminate a deflagration condition from causing damage to equipment and injury to employees has been proven highly effective. FENWAL Protection Systems used to eliminate deflagration problems are being applied around the world.
