Many industrial processes, including kraft recovery boilers, discharge spent gases to the atmosphere. Particulate matter emissions are strictly monitored in all industrial plants due to increasingly stringent government regulations. The purpose of an electrostatic precipitator, or ESP , is to remove particulate matter, or ash, from combustion discharge gases. This module describes the purpose, components, function, and safety guidelines of a precipitator.

The following key questions are answered in this module:
What is the purpose of an electrostatic precipitator?The purpose of an electrostatic precipitator is to remove particulate matter from discharged industrial gases.
How do electrostatic precipators capture particles?Electrostatic precipitators impart negative charge to incoming particles. The negatively charged particles are removed from the gas stream when they are attracted to positively charged collection plates.
How are captured particles removed from an ESP?Captured particles form a layer of dust on the collection plates. The plates are rapped or shaken to loosen the dust so it can fall to the bottom of the precipitator.
Can ESP's remove all pollution from a combustion gas stream?ESPs can only remove particulate matter, pollutant gases such as sulfur dioxide pass through.
What kind of electricity is used in an ESP?Electrostatic precipitators operate on very high direct current (DC) voltage.
