Combustible Dust: Preventing Accumulation

Dust explosions happen when five factors are present:

  • Oxygen
  • Ignition source
  • Dispersion of dust particles
  • Confinement of a dust cloud in a small space
  • Combustible dust

When dust gathers, it can become volatile. This applies to virtually any type of dust. Explosions have happened at flour mills, sugar processing plants, coal mines and even custard factories. For any application that can create clouds of accumulated dust, explosion prevention measures are absolutely necessary.

Removing one or more of the five elements of a dust explosion is essential. The dust is the fuel for dust explosions, so preventing dust from accumulating is a very important aspect of explosion mitigation. Dense phase pressure or vacuum pneumatic conveying help to move product through convey lines without causing it to break down – which means the material can move through the convey lines without creating a lot of dust.

It’s also important to make sure dust doesn’t collect in covey lines. Nol-Tec’s unique Air Assist technology moves material past critical chokepoints where dust accumulation is common.
