Electrostatic Precipitator (ESP) is an electric device to remove particulate matter present in the exhaust of thermal power plants. ESP has electrode wires and a stage of collecting plafes. Wires are provided with an electric current of several thousands volts, which produces a corona that releases electrons^) These electrons attach to dust particles, giving them a negative charge within a very small fraction of a second. Collecting plates are earthed, so that they attract charged dust particles. The velocity of air passing through plates is slow enough to allow the dust particles to fall on them.
How does an electrostatic precipitator work to remove particulate pollutants released from the thermal power plants?
