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
