Electrostatic precipitator process in fly ash capture in india ppt

Sep 22, 2016 Sep 22, 2016 PRINCIPLES OF ELECTROSTATIC PRECIPITATOR Electrostatic precipitation is a method of dust collection that uses electrostatic forces, and consists of discharge wires and collecting plates. A high voltage is applied to the discharge wires to form an electrical field between the wires and the collecting plates, and also ionizes the gas around the discharge wires to supply ions
