What is electrostatic precipitator in thermal power plant?

What is the function 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 is installed?

An ESP can be installed at one of two locations. Most ESPs are installed downstream of the air heater, where the temperature of the flue gas is between 130 and 180 °C. An ESP installed downstream of the air heater is known as a “cold-side” ESP.

How does an electrostatic precipitator work GCSE?

Electrostatic precipitators

Smoke comprises tiny solid particles, such as unreacted carbon, which can damage buildings and cause breathing difficulties. … Smoke particles pick up a negative charge. Smoke particles are attracted to the collecting plates. Collecting plates are knocked to remove the smoke particles.

How does an electrostatic separator work?

The electrostatic plate separators work by passing a stream of particles over a charged anode. The electrostatic minerals lose electrons to the plate and are pulled away from other particles due to induced attraction to the anode.

What is electrostatic precipitator PDF?

An electrostatic precipitator (ESP) is a particle control device that uses electrical forces to move the particles out of the flowing gas stream and onto collector plates. The particles are given an electrical charge by forcing them to pass through a corona, a region in which gaseous ions flow.
