Review DRAFT B.2 ELECTROSTATIC …
Background. Electrostatic precipitators (ESPs) use electrical energy to remove PM from exhaust gas streams. As the exhaust stream enters an ESP, PM in the gas encounters negatively charged ions, which apply a charge to the particles. The charged particles then are attracted to collector plates carrying the opposite charge.

Design of a novel closed-loop SOI MEMS resonant electrostatic field
A novel closed-loop SOI MEMS resonant electrostatic field sensor (EFS) has been designed in this paper. The sensor architecture has three major blocks: a vibration shutter, sensing electrodes, and a closed-loop driving electrode that feeds back to the shutter. With a phase and an amplitude closed loop feedback control, the sensor can be ...
Wet Electrostatic Precipitator for Pellet Mills
Wet Electrostatic Precipitator (WESP) - A Wet Electrostatic Precipitator is the most suitable technology for this problem. A WESP has a higher capital cost than a Venturi system, but the removal efficiency is independent of the particle size. It is most often used in situations where there is a high concentration of sub-micron particulates and ...
