Electrostatic Precipitators

Electrostatic precipitators (ESP) are particulate collection devices that remove particles from a flue gas by using the force of an induced  electrostatic charge. ESPs have a highly efficient filtration performance with a minimal reduction of pressure loss. They can easily remove fine particulate matter such as dust and smoke from the flue gas stream.

  • Balcke-Dürr/ROTHEMÜHLE® ESPs are state-of-the-art technology with a large number of patented developments
  • Our ESPs fulfill all current requirements with high dust removal efficiency and minimal power consumption
  • High security for our costumers with an experience of more than 1,000 supplied plants worldwide
  • Extreme stability in operation-long-lasting with low maintenance - due to robust design and proven components
  • Future targeted through modernizations which are part of the design concept such as Bi-Corona®

DELTA WING® Technology

Balcke-Dürr’s DELTA WING® technology homogenizes gas and dust distribution at the ESP inlet and in the raw gas ducts

Increases collection efficiency

  • Better utilization of the existing total collecting area thanks to the homogenization of the gas and dust distribution

Reduces pressure loss

  • Partial elimination of guide plates and perforated plates reduces ID fan power consumption by up to 15%

Long-Electrode Technology

Balcke-Dürr’s large electrode height offers minimal footprint with constant collecting area.

Extension of electrode height  reduces investment costs

  • Smaller foundation
  • Reduced electrical wiring
  • Smaller support structure

Bi-Corona® Technology

Balcke-Dürr’s Bi-Corona ® technology with optimized electrode geometry separates the  ionization and collection zones in the ESP.

Reduces electric auxiliary power consumption

  • Reduction in auxiliary power consumption by up to 10 % thanks to optimized electrode geometry

Increases collection efficiency for fine particulate PM2.5

  • Separation of ionization and collection zones results in lower electric wind and prevents collected PM2.5 fine particles from being entrained
