The waste incineration plants, power generation utility, chemical industry, etc. require the efficient removal of submicrometer particles from raw gases. Wet electrostatic precipitators (WESP) are the most effective control device for fine aerosol from the humid raw gases. They use less energy than mechanical collection devices, have no moving parts to wear, their maintenance costs are lower, p...
We use a hydrodynamic minimal streamer model to study negative corona discharge. By reformulating the model in terms of a quantity called a shielding factor, we deduce laws for the evolution in time of both the radius and intensity of the ionization fronts. We also compute the evolution of the front thickness under the conditions for which it diffuses due to the geometry of the problem and show...
Acid-base Reactions Induced by a Plasma Phase on Liquid Targets : Bronsted Acidity and Oxo Synthesis
The interactions between liquid targets and plasmas provided by a d.c. point-to-plane corona device operated under p = 1 atm. are considered in terms of both Bronsted and Lewis acid-base reactions. The treatments of aqueous solutions by the chargeless species of air or NH3 plasmas increase the Bronsted acidity of the target, and for an air plasma, the pH decrease is a linear function of the qua...
Wood is often combusted in small scale units for domestic heating. Although the total particle emission levels in Germany have declined steadily over the years, small scale wood combustion is an increasing source of indoor and outdoor air pollution. A novel space charge electrostatic precipitator (ESP) was developed for control of fine particle emissions control from wood combustion stoves and ...
