Preventing Combustible Dust Explosions

Dust explosions are lethal. When a cloud of dust ignites, it creates a fireball that can cause serious damage and take lives. Combustible dust has caused explosions all over the world in all types of facilities, from sugar processing plants to coal mines. Any time dust collects, explosion is possible.

So how do you prevent combustible dust explosions?

Preventing explosion is simple: you have to remove one or more of the five factors that lead to dust explosions. One of those factors is an ignition source. A common ignition source in dust explosions are system components that are out of alignment. For example, belts or bearings that are inefficiently situated can overheat.

Taking moving parts like these out of the equation significantly reduces possible ignition sources. Pneumatic conveying keeps moving parts to a minimum. Fewer moving parts mean less friction and less risk.

Nol-Tec can help you reduce risk even further by eliminating oxygen from convey lines and replacing it with inert gasses. We also take steps to prevent dust from accumulating. By taking these three steps, we remove three of the five factors necessary to create an explosion.
