Experiments were conducted in a wire-tube arrangement with a high loading of liquid submicron particles causing strong space charge effects, also known as corona quenching. The experiments are supplemented by numerical simulation results showing the effect of residence time and power consumption on separation efficiency.

After a short review of the physical fundamentals it is explained why measurements of the pressure gradient play an important role in the design principles for this technology. Its external influence by operating parameters like voltage polarity and aerosol conditions will also be shown. In the second part, the feasibility of enhanced mass and heat transfer is demonstrated based on laboratory measurements. In combination with the previously discussed pressure gradient measurements, methods for simplified engineering concepts like equivalent mean flow velocities or turbulent diffusion coefficients are shown. The topic is rounded off by outlining a potential use in decentralized power generation.

Experiments were conducted in a wire-tube arrangement with a high loading of liquid submicron particles. The experiments are supplemented by numerical simulation results showing the effect of residence time and power consumption on separation efficiency. By combining the own experimental results with seemingly contradicting statements of the literature, the authors provide also some general guidelines for discharge electrode design when designing or upgrading electrostatic precipitator plants.
