Abstract
An improved procedure is disclosed for supplying the power to an electrostatic precipitation system of the type wherein an underlying dc field serves to charge the particulates and transport them out of the stream of gas, while the corona which is required to yield ions to charge the entrained particulates is provided by a high, repetitively pulsed, electric field between the corona electrodes and collecting electrodes. The present disclosure reduces overall power input by connecting the corona electrodes in series and applying very narrow, frequent and high-amplitude pulses to one end of the series-connected cathode wire structure so that the pulses are propagated along the structure, thereby pulse-charging only a small portion of the precipitator at any given instant of time.
