When a combustible material, an ignition source and atmospheric oxygen collide in a confined space, the result is an explosion. Preventative explosion safety measures aim to stop this potentially lethal mixture from occurring. However, in practice, the vast number of potential ignition sources alone almost always makes this impossible. Consequently, the most important steps towards explosion safety for industrial companies are protection measures that minimise the damage caused by an explosion. Industrial plants must always be protected against the consequences of explosions to ensure that employees are safe and production can be resumed quickly. After all, every hour of lost production costs money. In most cases, explosion safety can be provided cost-effectively through explosion venting and explosion suppression.

Explosion vents

In the case of an explosion, an explosion vent will rupture and thus protect the vessel by reducing the overpressure within it and releasing the explosion into the surrounding environment in a controlled manner. Industrial processes vary widely depending on the sector and the product. No two processes are identical. For this reason, REMBE® supplies explosion vents in a variety of different shapes, materials, temperature and pressure resistances and many other specifications.

Types of explosion vents:
Application Operating conditions Product
Silo/Vessel Mechanical filling
Pneumatic filling
Filter/Cyclone Overpressure or low vakuum
Low to medium vacuum or pressure cycling
High vakuum or pressure cycling
Elevator/Chain conveyor All EGV
Spray dryer Hygienic requirements to avoid cross contamination
No hygienic requirements
Screen/Sieve Slight vibration
Strong vibration
Gas motors All EDP

Flameless explosion venting

During flameless explosion venting, the flames are cooled rapidly and efficiently in the mesh filter of the flame absorber and extinguished immediately. No flames and no pressure wave exit the vessel. The production plant can now be designed to create the optimum proces conditions. Likewise, the typical pressure wave and noise in the production hall are reduced to a barely perceptible minimum. The filter design guarantees that no burned or combustible materials are ejected. This not only reduces the consequences of the explosion, but also provides the highest level of protection for employees. Types of flameless vents:
  • Q-ROHR
  • Q-BOX

Explosion isolation

The objective of explosion isolation or decoupling is to protect adjacent parts of the plant and prevent the explosion from propagating. Explosion isolation is mandatory – secondary explosions in interconnected vessels would cause a high risk.

Types of explosion vents:

Explosion suppression Q-BIC

Explosion safety includes explosion suppression as well as explosion venting and isolation. This method extinguishes the explosion just as it is beginning – and well before the pressure rises to a critical level. Explosion suppression systems use sensors to detect sparks, flames and pressure build-up as they are created and instantly open connected containers of extinguishing agent. In the blink of an eye, they discharge a highly effective extinguishing powder and smother the germ of the explosion.
