“…Ähnliche Messungen wurden von Kallio und Stock [4] durchgeführt. Schmid [5] entwickelte ein Modell, um die Partikeldynamik in einem Elektroabscheider zu simulieren und Kaiser et al [6] ein Modell zur Berücksichtigung hoher Beladungen, was zu sog. Corona-Quenching führt.…”

Size Resolved Droplet Velocity Measurements in an Electrostatic PrecipitatorThe particle velocities in a 3-wire electrostatic precipitator were measured by the Phase-Doppler technique. The drift velocities of the seeding aerosols showed much larger values than expected based on their estimated charge, which indicated the presence of ionic winds. The significant gradients of the aerosol concentration led to increased drift velocities. Drift velocities of the water droplets increased linearly with droplet size and the data allowed an estimation of the combination of ionic wind and turbulent drift velocities.

“…The modelling of electrostatic precipitator (ESP) has been the subject of many papers [7][8][9][10][11][12][13], but none has used the method of experimental designs which proved to be a good tool for the optimization of such processes. The method used in this paper is to determine a mathematical model for the ESP process of a laboratory model, which will be used to determine optimal values of process factors and also for predicting the outcome of the process for randomly values of the factors.…”

Identification of the optimal operating conditions and evaluation of their robustness are critical issues for industrial processes. A standard procedure, for modelling a laboratory-scale wire-to-cylinder electrostatic precipitator and for guiding the research of the set point, is presented. The procedure consists of formulating a set of recommendations regarding the choice of parameter values for electrostatic precipitation. The experiments were carried out on a laboratory cylindrical precipitator, built by one of the authors, with samples of wood particles. The parameters considered are the applied high voltage U, the air flow F, and the quantity of dust in air m. Several ''one-factor-at-a-time'' followed by factorial composite design experiments were performed, based on the following three-step strategy: 1) Identify the domain of variation of the variables; 2) Determine the mathematical model of the process outcome; 3) Validation of the mathematical model and optimisation of the process.
