An electrostatic precipitator (ESP) is a filtration 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 therefore is very efficient in its consumption of energy (in the form of electricity).Boryeong Thermal Power Plant Units 1~8 (8 x 500MW).Our dry type electrostatic precipitators are quite successful in achieving the performance in power plant, steel plant, cement plant and other industrial applications for renovation & modernization projects as well as green field projects by EPC turnkey basis.

 

 

Wet Type Horizontal Flow ESP: Wet Electrostatic Precipitators (WESPs) are used to remove dust particles or other undesirable materials (usually aerosols of non-volatile compounds) from fuel or syngas streams. KC Cottrell has supplied several hundreds of such systems throughout the world. Currently, there is a growing demand for WESPs to clean syngas produced in waste-to-energy/energy-from-waste plants using gasification processes.
Wet type ESP has many similarities with the dry type unit in terms of principle and design. However, a basic difference is that the wet type is used in environments where the gas temperature is at or below dew point. Also, the rapping gear associated with dry units is replaced by an intermittent wash-down system using water or other liquids from the collecting plate.Wet type ESP collects particulates that are sticky or suspended in the flue gas close to saturation temperature. It can also capture high resistance particulates and substances in a gaseous state.The best advantage of this ESP is it can achieve high dust removal efficiency without being influenced by high or low resistivity of dust and as a consequence, a low emission can be achieved.
