Electrostatic Precipitator Concepts

An electrostatic precipitator (ESP) removes carbon and dust particles from gas streams by charging them electrically. Charged particles are attracted to collector plates with the opposite charge. ESPs can remove particles as dry or wet material, achieving over 99% efficiency. Key components include gas distribution plates, discharge electrodes, collection surfaces, and a wrapping system. Gas distribution plates ensure proper flow, while discharge electrodes charge particles. Collection surfaces capture particles, and the wrapping system removes them.

What is the primary function of an electrostatic precipitator?

• To remove carbon and dust particles

• To increase gas pressure

• To heat the gas stream

• To cool the gas stream

How are particles charged in an ESP?
