Precipitator Optimization

29.1 The Requirement of “Synergy”

To achieve the highest performance at lowest cost, few air pollution control devices require more “synergy”, more “balance” between the primary and ancillary components than precipitators. The “primary” components are the vessel, the “can”, and the ancillary components are the devices used to make the “can” work.

Whether a dry or wet design, these components must all work together. Changing a process or moving a precipitator to a new or modified process often requires going back to the beginning. For a dry application, resistivity testing of the particulate may be required. If acidic or other corrosive gases are now part of the input contaminant mix adjustments may be required. ...
