  • This will be used for exhaust gas purification in one Exhaust pipe used a heating system.
  • a capacitor is formed by the spray, which runs approximately centrally through the exhaust pipe and therefore also referred to as the center electrode, and a peripheral surface of the exhaust pipe, which is also referred to as a cylindrical capacitor in a cylindrical tube-shaped design of the exhaust pipe.
  • the spray or center electrode generally has a circular cross section in the flow direction of the exhaust gas, wherein the diameter of the cross section or the radius of curvature is generally formed relatively small (for example, less than 0.4 mm).

Due to this charge, most of the particles migrate through the electrostatic Coulomb forces to the inner wall of the exhaust pipe, which serves as a collector electrode.
  • the particles are electrostatically charged by the corona discharge which forms along the surface of the electrode.
