ESPs can be
grouped, or classified, according to a number of distinguishing features in
their design. These features include the following:
• The structural
design and operation of the discharge electrodes (rigid-frame, wires or plate)
and collection electrodes (tubular or plate)
• The method of
charging (single-stage or two-stage)
• The
temperature of operation (cold-side or hot-side)
• The method of
particle removal from collection surfaces (wet or dry)
These categories
are not mutually exclusive. For example, an ESP can be a rigid-frame, single- stage,
cold-side, plate-type ESP as described below.
