Grit Arrestors and Bag Houses

Grit Arrestors/Multiclones are capable of achieving high efficiencies at a lower cost.

Grit Arrestors/Multiclones are sometimes used as pre-cleaners to heighten the efficiency of final stage cleaners such as the Vortex Pulse Jet Baghouse, Electrostatic Precipitator or Wet Scrubber.

However in some applications a Grit Arrestor/Multiclone is the only pollution control device that may be required for a system. Many boilers have the Grit Arrestor/Multiclone attached directly to the back end. Grit Arrestors/Multiclones assist to protect the induced draft fan from excessive wearing.

Some of the factors influencing the choice of Grit Arrestor/Multiclone are:

  • Particle size
  • Concentration and density
  • Gas flow volume and temperature
  • Allowable pressure drop
  • Required efficiency and space constraints
