Precipitators for Coal Fired Boilers


Ducon supplies Dry Electrostatic Precipitators for new applications, upgrade of existing installations and replacement parts. Ducon has operating installations at boilers of sizes up to 600 MW capacity.


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.


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.
