Improvement of Technological and Electric Performances for Plate- Type Electrostatic Precipitators with Three Sections

The plate-type electrostatic precipitators have long been used by industry applications as the preferred method for controlling pollution with dust particles. The paper analyze the collection efficiency, for electrostatic precipitators with three sections (still, there is in industry applications), when are used different voltage supplies of electrostatic precipitators sections, the gas particles mass distributions, element average V- I curves, onset Corona voltage, spark discharge voltage, current density, collection efficiency, the inlet and the outlet dust concentration for different energization of sections. It's been performed an analysis of the total harmonic distortion coefficient of the current absorbed by the source, the supply voltage, the apparent and active power (for fundamental and harmonics), and the power factor (global, fundamental's and deforming) in situation when the current's value from the ESP field was superiorly limited.
