Explosion Suppression System and its Applications

Explosion suppression systems are designed to conquer or extinguish an eruption or deflagration from the start by reducing pressure build-up that would damage the process vessel or transfer line. In eruption suppression systems, a dynamic rate of the rising or static pressure sensor is used to detect the pressure increase due to combustion and, via the control panel.

It activates a pressure cylinder containing sodium bicarbonate, injecting a suppressor into the air stream, cooling the temperature of the fuel fireball and reducing the explosion pressure.

The characteristics of the ignition suppression systems over other mitigation techniques include:

1) Prevents pressure build-up and secondary eruption

2) Very fast response

3) Effective when ventilation panels cannot be used inside the building

4) It can be added as an insulating component instead of a valve

Explosion suppression systems are critical and require the necessary protection for applications such as:

1) Dust Collection Systems- Eruption suppression and/or insulation is a common option included in such systems where cleaning of the compressed air filter cartridge creates a dust cloud.

2) Spray Drying System- Due to the large volume of potentially explosive material, an explosion suppression system is required.

3) Liquid Dryer/Cooler- Combustible process materials require an effective eruption prevention system.

4) Flash Dryer- Explosion-proof required due to flammable dust hazard.

5) Grinding System- The combination of flammable dust and ignition hazards from moving parts requires an explosion suppression system.
