Applications range from electrostatic precipitator to electrostatic coating and inkjet printing. For combined removal of liquid droplets and particulates, a wet electrostatic precipitator is used. Post combustion, the mixture of flue gases and ash passes over an Electrostatic Precipitator (ESP). It also supplies high and low pressure pulse jet fabric filters, and electrostatic precipitator de-dusters. A noted product of the unit is an electrostatic precipitator used in energy generation facilities. In addition, other treatment systems also used are electrostatic precipitator and bag filters. Rectiformers are used for supplying power to different field of ESP (electrostatic precipitator). In 2004, Vectren replaced an existing electrostatic precipitator at Unit 1 with a fabric filter. The precipitator hopper outlets are electrically heated to facilitate dust extraction. Carbon can act, at first, like a high resistivity dust in the precipitator. The low-voltage, two-stage precipitator is generally used for filtration in air-conditioning systems. Cleaning a precipitator can usually be done without interrupting the airflow. Cleaned gases from the precipitator are compressed in a compressor. The first type of particles are solid and are called precipitator. Described below is the high-voltage, single-stage precipitator, which is widely used in minerals processing operations.
