METHOD FOR DETERMINING THE EXISTENCE OF AN OPTIMAL INTERVAL FOR RAPPING THE ELECTRODES OF AN ELECTROSTATIC PRECIPITATOR

摘要

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 it 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.
