What is the use of electrostatic precipitator?

electrostatic precipitator, also called electrostatic air cleaner, a device that uses an electric charge to remove certain impurities—either solid particles or liquid droplets—from air or other gases in smokestacks and other flues.

Where is electrostatic precipitator in thermal power plant?

The purpose of an ESP is to avoid these particulates being expelled into the atmosphere where they can cause pollution. ESPs are installed at many types of industrial plant, but they are most easily identified at thermal power plants where they are installed as part of the flue gas cleaning system.

What is the use of electrostatic precipitator in steam power plant Mcq?

The electrostatic precipitators (ESP) are extensively used in the thermal power plant or steam power plant for removal of fly ash from the electric utility boiler emissions.

Does an electrostatic precipitator remove so2?

An electrostatic precipitator for removing sulfur dioxide and other polluting particles has a wet liquid removal area or compartment down stream and in the last section of plates of the electrostatic precipitator.

What is the efficiency of electrostatic precipitator?

Design efficiencies are usually better than 99.5\%. Overall collection efficiencies of 99.7\%–99.9\% and fine particulate collection efficiencies >99\% are common. An FF consists of a large surface area of fabric, which collects dust particles from the flue gas passing through it.

How do catalytic converters work apes?

Inside a catalytic converter, a catalyst stimulates a chemical reaction in which noxious byproducts of combustion are converted to less toxic substances by way of catalysed chemical reactions.

What is electrostatic precipitator and how does it work?

What is an Electrostatic Precipitator? An electrostatic precipitator (ESP) is defined as a filtration device that is used to remove fine particles like smoke and fine dust from the flowing gas. It is the commonly used device for air pollution control. They are used in industries like steel plants, thermal energy plants.

What is a precipitator in a power plant?

The precipitator creates a charged electric field that attracts suspended particles onto a metallic surface and allows the flue gas to pass through the chimney. This is done primarily so that the area surrounding a power plant does not get covered in soot and ash.

How are dust particles collected in electrostatic precipitators?

The dust particles are collected from a stream of air by hammering the electrodes. Wet electrostatic precipitator: This precipitator is used to remove resin, oil, tar, paint that are wet in nature. It consists of collectors that are continuously sprayed with water making the collection of ionized particles from the sludge.

Are electrostatic precipitators the solution to factory smokestacks?

The industry is an integral part of our economic system and many believe that it is their right to put up with the factory smokestacks that choke up the air. But not many know that technology has a good solution to this for over a century in the shape of electrostatic precipitators. These greatly reduce pollution and help improve the environment.
