Abstract
A method of an apparatus for improving the capacity and efficiency of electrostatic precipitators by increasing the average field intensity. The precipitator is supplied with a substantially constant base level DC voltage that is less than the sparking threshold level of the precipitator, and superimposed thereon is a periodic DC voltage waveform of short duration having peak levels that substantially exceed the sparking threshold level. By controlling the characteristics of the periodic DC voltage waveform the average applied voltage is greater than the sparking voltage but the duration of the instantaneously applied voltage is not sufficient to cause sparking in the precipitator.
