The RIECO dry Electrostatic Precipitator (ESP) can be used to extract fine dust particles from process gases up to a temperature of 400 Celsius by means of an artificial electrostatic charge. The dust-laden process gas enters the ESP horizontally, and is spread to a uniform  flow profile across the entire filter cross-section by means of a gas distribution system. By means of the high voltage applied between the corona discharge electrodes and the collecting electrodes, the process gas and the dust particles are electrically charged. 

On the route through the electric field, the charged particles are transported to the collecting electrode plates by the electric field strength, where they agglomerate with the existing dust particles which are then knocked off by a motorized tumbling type Rapping Hammer System. The rapped off dust particles drop into the ESP hopper and are removed through the dust discharge system. The clean gas leaves the ESP through the gas outlet cone.
