What is electrostatic precipitator in thermal power plant?

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.

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.

What is the function of ESP in thermal power plant?

Electrostatic precipitators (ESP) collect dust in the flue gas produced by boiler, etc. Mitsubishi Power contributes to air pollution control at thermal power plants, steel plants , and various industrial plants.

Where is electrostatic precipitator are placed in thermal power plants?

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 function of electrostatic precipitator?

An electrostatic precipitator (ESP) removes particles from a gas stream by using electrical energy to charge particles either positively or negatively. The charged particles are then attracted to collector plates carrying the opposite charge.

What is the principle of electrostatic precipitator?

Electrostatic precipitators operate on the principle of the attraction of a charged particle for an oppositely charged collector. They have been used for both collecting particles for further analysis and for controlling particulate emissions from sources.

Where is electrostatic precipitator used?

6 days ago
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.

What is the role of electrostatic precipitator?

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.

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 advantage of electrostatic precipitator?

Advantages of electrostatic precipitator: It can be used for the collection of both dry and wet impurities. It has low operating costs. The collection efficiency of the device is high even for small particles. It can handle large gas volumes and heavy dust loads at low pressures.

What are the uses of electrostatic precipitator?

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.

What factors affect the performance of electrostatic precipitator?

The performance of electrostatic precipitator (ESP) is significantly affected by its complex flow distribution arising as a result of its complex inside geometry.

When did operation and maintenance manual for electrostatic precipitator come out?

Operation and Maintenance Manual For Electrostatic Precipitators. February 1981. 4. Industrial Gas Cleaning Institute, Inc. Bid Evaluation Form for Elec- trostatic Precipitators.

What are the electelectrostatic precipitator collection area requirements?

Electrostatic precipitators on BOF’s contain six to eight chambers with three to five fields per chamber. Collection area requirements, as shown in 9 Figure C-5, range from 200 to 600 ft /1000 acfm. The newer systems are at the high end of this range, and requirements on some are even higher.

What is a thermal power plant?

Page |1 INTRODUCTION: A thermal power plant converts heat energy of coal into electrical energy. coal is burnt in a boiler which converts water into steam. The expansion of the steam turbine produces mechanical power which drives the Excitation Generator (Alternator) coupled to the turbine.
