Electrostatic Precipitator Upgrade, Rebuild and Performance Enhancement
|
Many of the precipitators in operation today were sized and designed to meet performance
requirements that are far below current requirements. Time has also taken its toll on the
robust machines built many years ago. Most units can be upgraded, repaired or rebuilt to
extend their life and improve their performance. Hamon Research-Cottrell has the design
experience to insure that modifications meet the objectives of today's
precipitator operators.
Hundreds of precipitators have been modified to meet more stringent performance requirements.
Units built in the 1960s and 70s can often be modified to provide 15% to 20% more collecting
surface without increasing the footprint of the unit. The size of European design precipitators
can be increased 30% and more.

Other performance improvement strategies include:
- Increasing the width of the gas passages and replacing wires and weights with rigid discharge
electrodes will improve the reliability of the unit, as there will be no wires to break.
The precipitator performance will also be improved. Hamon Research-Cottrell has developed
and installed pipe and spike electrodes designed to provide the corona generating characteristics
needed for improved performance with out the replacement of the existing transformer-rectifier sets.
- Increasing the number of electrical bus sections will further improve the collection efficiency
of the precipitator.
-
Decreasing the amount of collecting surface that is served by each rapper.
