Ducon's Dry ESP's incorporate the latest advances in the microprocessor design technology and digital controls for enhanced performance and improved reliability. Ducon units have the following unique features:

  • Complete automatic energization systems including optimization of conduction angle thru variable inductance and high transformer impedance.
  • Heavy-duty rigid discharge electrodes design without any concentration of mechanical stress to insure long service.
  • Back corona detection and prevention for better performance with high resistivity particulate.
  • Rapper system is reciprocating type which is microprocessor based that allows intensity adjustment.

WET ELECTROSTATIC PRECIPITATORS

Ducon Wet Electrostatic Precipitators are available in both horizontal & vertical configuration and are designed to achieve zero opacity and over 99.9% removal efficiency on particles down to 0.01 micron in size (<0.5 mg/Nm3)with 0.5 w.c. pressure drop. In addition to power plants, Ducon also provides condensing type WetESP's for control of acid fumes & metal oxides. Ducon's design is non-clogging due to to wide spaced eletrodes.
