Start-Up Dust Control Systems

Fan or Blower System

Start the fan or blower and check for proper rotation.

Check dust pickup points for proper suction. Balance airflow in individual
ducts.

Check for air leakage at all flanged connections.

Equipment Start-Up Sequence

The compressed air supply system must be started first.

When the pressure gauge on the compressed air manifold indicates that
the system is at full pressure (90-100psig) the pulse timer can be
energized.

Dust take away equipment such as rotary airlocks, screw conveyors,
horizontal unloading valves, live bottom bin activators and pneumatic
conveying systems can now be started in their correct sequence.

Check that all access doors, hatches, ports, and other openings are
closed and latched or bolted.

The main exhaust fan can now be started and brought up to speed.

Start the dust-laden air through the collector. The collector should be
started under partial load to allow the bags to become slowly and evenly
coated with dust particles.


On pneumatic conveying systems watch the differential pressure gauge
closely for the first hour or so. If unstable, the collector discharge system
may be too small for the volume it is seeing. A quick fix is to reduce the
material feed until the discharge rate can be increased.

Observe the manometer or magnahelic differential pressure gauge
reading. As the new filter bags become coated with dust, the efficiency of
the filtering action increases and the differential pressure across the filter
bags will also increase. Slowly bring the collector to full load and note the
final pressure drop across the filter bags. Never allow the pressure drop
across the filter bags to exceed 17” w.g. maximum or the filter bags may
collapse.
