Abstract:
1. A method mitigating sparking in an electrostatic precipitator having a discharge electrode, a collecting electrode, and at least one resistor in series with the discharge electrode the method comprising: applying a current to the discharge electrode to form a voltage potential between the discharge electrode and collecting electrode; flowing a gas through the precipitator and through a gap between the discharge electrode and the collecting electrode, wherein the gas is ionized b the voltage potential; collecting charged particulates in the gas on the collecting electrode to remove the particulates from the gas; when a spark forms between the discharge electrode and the collecting electrode, reducing current flowing through the electrode by dissipating current in the at least one resistor; wherein the discharge electrode is a plurality of discharge electrodes arranged in sets and the method further comprises selecting a first resistor in series with a first set of discharge electrodes to have a higher resistance than a second resistor in series with the second set of discharge electrodes.
