The main function of Electrostatic Precipitators is the collection of particles from combustion gases in different industrial processes. With the emergence of the clean air concept and its strict limitations, collection efficiencies have increased to a range of up to 99.5% retention of particles contained in combustion product gases. To meet these stringent efficiency figures it has been necessary to change the design and size of the precipitators and the need for efficient operation with low maintenance has become a priority. Today refinement in operation, materials, and new inventions abound for electrostatic precipitators, including the discharge electrode, increased spread between plates, shaker controls, variable current limiters, and programs that allow operators to view the operating conditions of the electrostatic precipitator. precipitator and view other operating parameters.
