Electrostatic Precipitators (ESPs)

Choose the Correct Answer

Correct Answer : Option c

Explanation
Electrostatic Precipitators (ESPs) are devices used to remove particulate matter from industrial flue gases by applying an electric charge to particles and collecting them on oppositely charged plates. Their efficiency is influenced by factors such as collection surface area, gas-flow rates, particle resistivity, and the properties of the flue gas. They can remove over 99% of particulate matter present in the exhaust.

Statement 1 is correct: Electrostatic Precipitators (ESPs) use electrical forces to remove solid or liquid particles from industrial exhaust gases. High-voltage electrodes charge airborne particles, which then migrate to oppositely charged collection plates.

Statement 2 is correct: High moisture content in flue gas can reduce ESP efficiency by causing arcing (electrical discharges) and affecting the charging and collection of particles.
