Abstract
An improved procedure is disclosed for the electrostatic precipitation of particulates entrained in a stream of gas between corona electrodes and collecting electrodes. The underlying dc field which serves to charge the particulates and transport them out of the stream is relatively uniform and therefore can be relatively high, 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 the collecting electrodes. Embodiments are presented which suggest the manner in which conventional precipitators may be adapted to the present invention.
