Experimental studies in the electrostatic precipitation of high-resistivity particulate

A pulsed charging system is described that eliminates reverse ionization inelectrostatic precipitation. The motivating concept is a purely electrical approach. The fundamental characteristic of this method is the relaxation time of the precipitated particulate. Laboratory studies indicate that this powering concept could increase precipitator performance on high-resistivity particulate by more than two orders of magnitude. Pilot results are also presented.
