Abstract

A method for operationally determining the existence of an optimal rapping interval for the collector electrodes of an electrostatic precipitator comprises the comparison of the current-voltage characteristics for precipitator operation under pure-gas conditions and actual use conditions. If the comparison indicates that the resistance of accumulated dust layers is greater than the resistance of air, then an optimal rapping interval exists. This interval may be calculated analytically or approximated by means of an iterative process.
