Abstract:
1. A method of applying electrical energy to an electrostatic precipitator collector which enables operationally effective cleaning using electrical energy, comprising the steps of: applying electrical energy having a first electrical polarity to said electrostatic precipitator collector; collecting precipitate on said electrostatic precipitator collector responsive to said electrical energy applying step; determining a need for cleaning said electrostatic precipitator collector; measuring an instantaneous voltage across said electrostatic precipitator collector: calculating a capacitive source target voltage responsive to said instantaneous voltage measurement; charging a capacitive source to said capacitive target voltage; switching said applied electrical energy from said first electrical polarity to a second electrical polarity derived from said capacitive source and opposite in polarity from said first electrical polarity; thereby removing said collected precipitate from said electrostatic precipitator collector responsive to said switching step; and resetting said applied electrical energy to said first electrical polarity subsequent to said removing step.
