Explosion protection systems are one of the most important safety features in any manufacturing facility that deals with raw materials that have the potential to create combustible dust. Some of the most common raw materials that can create combustible dust include metal, wood, chemicals, grain, sugar, flour, textile fibers, and many other solid organic materials. When a rogue spark or other ignition source comes into contact with combustible dust within a closed vessel, it can lead to catastrophic explosions that can cause severe damage to a facility, equipment, and worst of all, employees. The best way to contain these explosions and limit the amount of damage they’re able to do is by using two key components of an explosion protection system: explosion suppression systems and explosion isolation valves!

Explosion Suppression

Explosion suppression systems are designed to detect and chemically extinguish explosions in their earliest stages, just milliseconds after their original ignition. Explosion suppression systems include a precisely calibrated pressure detector component that can sense the pressure wave that expands outward at the very moment that a potential explosion ignites. The pressure detector will then instantly send a signal to system’s suppressor, which will unleash highly-pressurized nitrogen into the vessel where the ignition is occurring, extinguishing the explosion before it has the chance to propagate through interconnected ductwork and cause devastating damage to the facility and surrounding equipment.

Explosion Isolation

The other components of an explosion protection system that are essential for preventing deflagrations that travel through interconnected ductwork & equipment are explosion isolation valves. Explosion isolation valves are used to mechanically contain explosions within the vessel where the ignition occurs, whereas explosion suppression systems are used to chemically suppress the ignition. When the pressure detector within a vessel senses an ignition, it will send a signal to the explosion isolation valves within milliseconds. When the explosion isolation valves receive this signal, the knife gate will instantly close, cutting off the explosion’s ability to travel into the interconnected ductwork and adjacent vessels. When explosion suppression systems and explosion isolation valves are properly installed, calibrated, and paired together, your facility will have the best protection possible from deflagrations that could otherwise propagate through interconnected ductwork and equipment!
