A number of vertical, parallel metal plates utilizing the mutual attraction of opposite electric charges to remove dust or ash particles or liquid droplets suspended in a gas.

frequently used to clean dust and fly-ash from many industrial processes. By maintaining a high voltage potential between wires and collector plates in the ESP, a charge is induced onto the dust particles, and the dust particles are then electrostatically attracted to the collector plates.

an air pollution abatement device that removes particulate matter from a gas stream by imparting an electrical charge to the particles for mechanical collection on an electrode

An air pollution control device that removes particles from a gas stream (smoke) after combustion occurs. The ESP electrically charges the particles, causing them to adhere to metal plates inside the precipitator, from which they can be retrieved for disposal.

A type of particulate filtration control that attracts charged particles to oppositely charged surfaces to collect airborne particulates. In this process, the particles are charged by ionizing the air with an electric field. The charged particles are then collected by a strong electric field generated between oppositely-charged electrodes.

A device which uses an electric field to trap particulate pollutants.

A device that removes particles from airflow by using the attractive properties of opposite electric charges.

A device that removes particles of smoke from waste gases. Electricity and magnetism

A type of air pollution control system that uses high voltage fields to electrically charge and collect particulate matter. The charged particles approach an electrically grounded collection plate and accumulate as a dust layer, which is partially removed by mechanical rapping (hammers) on a routine basis.

A system in some air cleaners that uses a weak electric charge to attract tiny allergen particles, thus removing them from the air.

An electrostatic device in power plant chimney flues that removes solid particles from esca

An air-pollution control device that removes particles from an air stream. The ESP imparts an electrical charge to particles causing them to adhere to metal plates inside the precipitator.

An electronic pollution-control device that removes particles of fly ash from a power plant's waste gases.

A device which extracts particles from combustion gases prior to release from a power plant’s stack.

Used to clean up flue and process gases. Removes 99.5-99.8% of dust particles emitted from recovery boilers, lime kilns and bark-fired boilers

A device used to remove particulate matter from the waste gasses of a combustion power plant.

A device that removes fly ash particulate matter from combustion gases to prevent them from escaping through exhaust. It consists of vertical metal plates that use an electric charge to create static and capture the particles so they can be contained and removed. A “hot” electrostatic precipitator removes fly ash particulates before they enter the air preheater unit; a “cold” electrostatic precipitator removes fly ash particulates after they enter the air preheater unit. Each hot electrostatic precipitator at Potomac River has a particulate collecting area equivalent to six acres. This is approximately three times larger than typical units of this type.

equipment in which particles in gas streams are passed through ionisers and become charged, facilitating their subsequent removal

A device that removes particles from a gas stream (smoke) after combustion occurs. The ESP imparts an electrical charge to the particles, causing them to adhere to metal plates inside the precipitator. Rapping on the plates causes the particles to fall into a hopper for disposal.

The two types of electrostatic precipitators are the Cottrell-type (single-stage) and the Penny-type (two-stage). The Cottrell-type combines ionization and collection in the same field while the Penney-type places the ionizer and the collection plates. With either type, particles entering the ionization field receive an electrostatic charge. These charged particles are then collected on the grounded collection plates. The Cottrell single-stage precipitator operates at ionization voltages from 40,000 to 70,000 colts DC. It may also be called a high voltage precipitator and is used to collect particles in application such as utility boilers. The Penney two-stage precipitator uses DC voltages from 11,000 to 14,000 for ionization and is frequently referred to as low voltage precipitator. It is used to collect contaminants in applications such as welding or oil mist and smoke from machining operations. UAS manufactures the SMOG-HOP line of Penney-type, two-stage electrostatic precipitators.

A device for removing particulate matter from smokestack exhaust gas by imparting an electric charge to the particles and then attracting them to a metal plate or screen of opposite charge before the gas is exhausted out of the top of the stack.

An electrostatic precipitator (ESP), or electrostatic air cleaner is a particulate collection device that removes particles from a flowing gas (such as air) using the force of an induced electrostatic charge.
