An electrostatic precipitator (ESP) is a particle control device that uses electrical forces to move the particles out of the flowing gas stream and onto collector plates. The particles are given an electrical charge by forcing them to pass through a corona, a region in which gaseous ions flow.
The main goal of using electrostatic precipitators)ESPs(is to reduce pollutants emitted into the atmosphere, and the ESP can eliminate more than 99 % of particles in exhaust without forcing the gases through a filter [1].ESPs are utilized in various industries, such as coal power plants, cement corporations, chemical industries, metal manufacturing industries, and glass and …

More nickel laterite ores are imported into China because of the depletion of domestic nickel sulfide resources. Consequently, it is of great importance to the Chinese economy to effectively utilize low grade nickel laterite ore [7]. Nickel laterite ores are formed by the weathering of olivine bedrock in tropical to sub-tropical climates [8,9].
Two electrodes within the electrostatic precipitator produce the electrostatic charge. They can be bars, metal wires, or plates. Once the charge is produced, particulate matter is attracted to and trapped inside the precipitator. The plates within an electrostatic precipitator require occasional cleaning to remove the accumulated particulate ...
