A dry electrostatic precipitator (ESP) electrically charges the ash particles and imparts a strong electric field in the flue gas to collect and remove them. An ESP is comprised of a series of parallel, vertical metallic plates (collecting electrodes) forming lanes through which the flue gas passes.

What are the disadvantages of electrostatic precipitator?
Electrostatic precipitators have a high initial capital cost, which makes it prohibitive for small-scale industries. They are expensive to purchase and install. In addition to being costly, they require large space to be set up.
How much does an electrostatic precipitator cost?
Cost Effectiveness: $73 to $720 per metric ton ($65 to $660 per ton) Theory of Operation: An ESP is a particulate control device that uses electrical forces to move particles entrained within an exhaust stream onto collection surfaces.
How does an electrostatic precipitator reduce pollution?
The electrostatic precipitator works by removing particles and smoke from a gas stream using an electrostatic charge. … Introducing a water spray can reduce the electrical resistance of the dust particles, allowing them to accept the charge more easily.
Why do you think that some factories might not use electrostatic precipitators?
Factories don’t use electrostatic precipitators because of the high cost associated with it. Explanation: Invented by Frederick Cottrel, an American inventor and physical chemist, the electrostatic precipitator was originally used to recover industrial materials from output materials.
In which kind of application high voltage electrostatic precipitators are preferably utilized?
Electrostatic precipitators are commonly used for collecting particles mostly in industrial plants.
What is Corona ESP?
An important un-dust device is plate-type electrostatic precipitator (ESP). It is used in power plant, cement, steel and glass industries. … The back-Corona phenomenon is specific for high resistance dust and consists in a series of micro-discharges between the particles from dust layer on the collecting plates.
What is the principle of ESP?
Working Principle of ESP
An ESP works on the principle of the corona discharge effect. A high DC voltage is applied across the two plates or electrodes. The negatively charged plate attracts the dust particles which are further attracted by the positively charged electrode by the process of Ionisation.
Does an electrostatic precipitator remove co2?
These unburned particles of carbon are pulled out of the smoke by using static electricity in the precipitators, leaving clean, hot air to escape the smokestacks. It is vital to remove this unreacted carbon from the smoke, as it can damage buildings and harm human health – especially respiratory health.
How is electrostatic precipitator used?
Originally designed for recovery of valuable industrial-process materials, electrostatic precipitators are used for air pollution control, particularly for removing harmful particulate matter from waste gases at industrial facilities and power-generating stations.
How does an electrostatic work?
Electrostatic forces are non-contact forces; they pull or push on objects without touching them. Rubbing some materials together can result in something called ‘charge’ being moved from one surface to the other. Charged objects pull on other uncharged objects and may either push or pull on other charged objects.
How do you clean an electrostatic precipitator?
Mix hot water with the detergent thoroughly and then immerse the precipitator cell in for 1-2 minutes. Take it out of the mixture and let it stand for 5-7 minutes or rinse immediately depending on the mix and instructions.
Who invented electrostatic precipitator?
Frederick Cottrell invented the “electrostatic precipitator,” which removes pollutants from smoke. Cottrell was born on January 10, 1877, in Oakland, California, the son of Henry and Cynthia Cottrell. His ingenuity and interest in the applied sciences were demonstrated early on.
How does pollution control use static electricity?
Static electricity is used in pollution control by applying a static charge to dirt particles in the air and then collecting those charged particles on a plate or collector of the opposite electrical charge. Such devices are often called electrostatic precipitators. … They give the smoke an electric charge.
What are 10 ways to reduce air pollution?

What is the highest source of outdoor air pollution?
The common sources of outdoor air pollution are emissions caused by combustion processes from motor vehicles, solid fuel burning and industry. Other pollution sources include smoke from bushfires, windblown dust, and biogenic emissions from vegetation (pollen and mould spores).
Why is the installation of electrostatic precipitator recommended?
Why is the installation of an electrostatic precipitator recommended? The installation of an electrostatic precipitator for wood stoves, such as the OekoTube, is recommended to drastically reduce the emissions of PM10 or smaller, ultimately for the protection of human health.
What are the types of electrostatic precipitator?
There are four basic types of ESPs: plate and wire (dry), flat plate (dry), wet, and two-stage. ESPs provide a large air volume, operate favourably in various temperatures, and require little maintenance.
What is the maximum efficiency of electrostatic precipitator?
The maximum efficiency of an electrostatic precipitator is 99%.
What is EP dust?
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.
