Dust Entrainment
Issue:
Excessive entrainment of dust with the cleaned air may be due to the
following:
Fix:
•
Equipment running dry or with insufficient water – because of
clogged spray nozzles or strainer, or low water pressure, (40 lb.
minimum pressure required at nozzles).
•
Obstructions in impeller blade hooks.
•
On Arrangement D, spray nozzle in pre-cleaner turned. Flat spray
must discharge in a vertical plane.
•
Dust loading too heavy.
•
Particulate size too small to be captured.
•
Disturbances at inlet, such as elbows or branch entries, causing
unbalanced airflow or dust loading (see Section 9.2.7).
