An electrostatic precipitator (ESP) is a filterless device that removes fine particles, like dust and smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding the flow of gases through the unit.. In contrast to wet scrubbers, which apply energy directly to the flowing fluid medium, an ESP applies energy only to the particulate matter being collected and ...

In the past fly ash was released into the atmosphere, but local and regional pollution control standards now require that it is captured prior to release, usually by either mechanical or electrostatic separators. The collected fly ash is stored in silos for later disposal or beneficial re-uses. About 43% of the estimated 22 million tons (20 ...

1.3.1 History of Electrostatic Separation: Electrostatic separation of ash from coal was first done in 1914 by Withington and subsequently two patents came out in the following year.

electrostatic separation, gravitational separation, or froth flotation. Various studies have been carried out on the recovery of combustibles from ash materials2–5. Studies showed that froth flotation is the most efficient method for the removal of unburned carbon, compared to electrostatic or other physical cleaning techniques6,7.

At present, electrical selection is widely used in the following areas: 1. Sorting of non-ferrous and rare metal minerals These two types of minerals are often firstly subjected to gravity separation or other beneficiation methods to remove a large amount of gangue minerals or surrounding rocks to obtain a certain grade of coarse concentrate, which is then selected by electric separation or in ...
