Abstract

In an electrostatic precipitator which is supplied with energy in the form of d.c. voltage pulses or of a d.c. voltage and superposed pulses, the energy supply is optimized and reverse corona discharges are avoided by use of a method in which energy at the highest possible rate is supplied to the electrostatic precipitator during the pulsing period and the total energy consumption of the electrostatic precipitator required to achieve in the pure gas a predetermined maximum dust content is minimized in that the pulse parameters are optimized and the application of pulses is interrupted for the longest possible non-pulsing time which is consistent with the predetermined maximum dust content of the pure gas.
