Electrostatic Precipitators

Main focus of work:

 

  • Fundamental study and application of corona discharge
     
  • Electrostatic precipitators for small combustion facilities (CAROLA - www.carola-clean-air.com/index.php/de/)
     
  • Development of space charge electrostatic precipitators for industrial applications (reduction of fine particles emissions from combustion processes, precipitation of acid aerosol from industrial exhaust gases, condensation of oil mist from biomass and plastics pyrolysis gases using electrohydrodynamic phenomena).
