Precipitator Discharge Electrodes

Electrostatic precipitators apply an electrical charge to the particulate which causes them to move to the grounded collector plate.

The discharge electrodes, which operate at high voltage, provide the source of electrical charge by creating a corona discharge.  The discharge electrode design, its relation to the collecting plate, and the nature of the particulate and gas flow, influence the amount of corona discharge that can be applied without excessive sparking.

While many electrostatic precipitators still operate with traditional weighted wire discharge electrodes, today's design has evolved in order to enhance reliability.  This new design incorporates rigid pipe and spike electrodes which can be tailored to the specific requirements for different applications.

To this end, discharge electrodes are offered in a variety of configurations which typically adjust the number and orientation of the emitting spikes depending on the expected level of corona suppression as may be encountered from higher concentrations of fine particulate.
