What is Electrostatic Precipitator?

This device is used for removing fly ash after the combustion of coal or other materials. After the combustion of coal and other materials, polluted gas or smoke enters the electrostatic precipitator.

  • The device is electronically charged. The polluted air and impurities become negatively charged as they gain electrons on their surface.
  • Negatively charged dust particles are then drawn towards the positively charged electrode plates and are deposited there.
  • Impurities are then dislodged by mechanical rappers and get collected at the bottom of the unit in a hopper.
  • An electrostatic precipitator is a very efficient device that removes more than 99% of impurities.
