An analysis on the optimal fields number of the plate-type electrostatic precipitators used in a thermoelectric power plant

The most used deduster in industrial applications are plate-type electrostatic precipitators. They can treat high gas flows obtained from various burning processes, but their price is high. These costs depend mostly on the number of fields. An analysis was performed using experimental data collected from different plate-type electrostatic precipitators in a thermoelectric power plant. The following items were analysed: the collection efficiency, the speed distribution of the dust particles in the fields, and some electrical parameters for three types of electrostatic precipitators: with two, three and four fields.
