The dangers of industrial explosions have been known for hundreds of years. Substances that are hazardous to dust explosions are handled in many industries and there are legal requirements for precautions to protect personnel and equipment.
Explosion protection techniques aim to minimize or eliminate the occurrence of explosions, while explosion protection techniques control the effects of explosions by minimizing the damage that can be caused by explosions.
Explosion protection techniques include containment, flameless ventilation, explosive ventilation, suppression, and isolation. For proper installation and operation, consult a flameless explosion vents supplier via the internet.
A new option – flameless ventilation – has recently been developed for dust explosions and is actively being marketed as an alternative to ventilation ducts. The fireless ventilation device combines explosion and fire suppression techniques. A fireless ventilation device usually consists of a vent panel, flanged housing, and a flame arrestor element.
The general principle is that at the initial stage of the explosion, the explosion vent cover opens, and unburned dust and fire enter the refractory element. The spread of fire outside the device is prevented by the dissipation of energy (heat) within the element, which lowers the burning fuel below its ignition temperature.
Advantages of flameless venting are flame extinguishment, dust retention, elimination of the need for explosion vent ducts, and minimization of the vent relief area requirements for indoor venting.
