Feb 24, 2012 Electrostatic precipitators have become the norm now in industries. Due to strict regulation and ever-increasing air pollution, installing one in a thermal power plant or any other power plants where flue gases are released, have become a necessity. But whether electrostatic precipitators perform the function expected from them can be determined by measuring the efficiency of the device.
Efficiency of Electrostatic Precipitator eta 1-efrac-WAQ where, is the fractional collection efficiency. W is the terminal drift velocity in ms-1. A is the total collection area in m 2. Q is the volumetric air flow rate in m 3 s-1. Types of Electrostatic Precipitator

Introduction. The electrostatic precipitator ESP is a piece of equipment that is used to capture dust particles that are formed or liberated by various industrial processes.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 ...
An electrostatic precipitator is such an ion propulsion engine. Although it ... due to thermal diffusion of ions in the gas. The rate depends on the ion density, ion mobility, and time, and is ... Precipitator Efficiency The dust removal efficiency of a pre-cipitator can be written as 5
May 17, 2011 Electrostatic Precipitator is a technique used to decrease the pollution content in the flue gasses. It is generally used in Thermal power plants to control the pollution caused by flue gasses. In this article I will explain about the working, advantages and disadvantages of an Electrostatic Precipitator.
Sep 09, 2020 Systems and equipment available to plant engineers include wet and dry flue-gas scrubbers, cyclones, fabric filters, thermal oxidizers and dry electrostatic precipitators. These types of systems can be cost-effective in controlling large-scale particulates, oxides of sulfur and nitrogen and other hazardous air pollutants.
Jul 01, 2011 1. Introduction. Electro-Static-Precipitators ESPs are widely used , in the electric utility industry for removing particles from flue gas generated in coal-fired boilers. Most of the existing ESPs have been in service for 15 years or more and their performance has inevitably deteriorates with age.In the light of increasing pressure to comply air-quality standards, it is imperative that ...
Feb 24, 2012 The efficiency of the electrostatic precipitator is dependent on the particle size of the aerosol dust, mist to be collected. The collection efficiency if high for more massive particles and low for small particles. The formula to calculate the efficiency

Jan 31, 2021 Advantages of electrostatic precipitator are as follows. Electrostatic precipitators have excellent efficiency and can be used to remove 99 of dust particles from impure air. They are capable of collecting both dry and wet pollutants. Dry precipitators collect dry pollutants, while wet precipitants collect humid pollutants.
The collection efficiency of an electrostatic precipitator depends mainly on the resistivity and the particle size distribution both properties can be determined at laboratory scale. 77 A widely used model to calculate this efficiency is the Deutsch model, which assumes infinite remixing of the particles perpendicular to the stream.
Electrostatic precipitator technology was developed in the United States by Dr. Fredrick Gardner at the turn of the century. Frederick Cottrells precipitator was successfully applied in 1907 to the collection of sulfuric acid mist and shortly thereafter proven in a number of
Feb 24, 2012 Electrostatic precipitators are ubiquitous nowadays in thermal power plants due to ever-increasing concern about environmental pollution. Electrostatic precipitator uses the high-intensity electric field to ionise the dust particles in the air stream and then the dust particles are collected by oppositely charged collectors electrodes. The dust particles, once collected are
An electrostatic precipitator ESP is an effective method of particulate collection in power generation applications. Its history dates back to the early 20th century. Of course, technology upgrades to enhance performance have continued for nearly as long. We have prepared a two-part article discussing ESP operation and some of the available upgrades and modifications now available for new ...
An electrostatic precipitator is a type of filter dry scrubber that uses static electricity to remove soot and ash from exhaust fumes before they exit the smokestacks. This one common air pollution control device.Most power stations burn fossil fuels such as coal or oil to generate electricity for use. When these fuels undergo combustion, smoke is produced. ...
An electrostatic precipitator ESP is a filtration device which removes fine particles, like dust and smoke from a flowing gas using the force of an included electrostatic charge minimally impeding the flow of gases through the unit.
The electrostatic precipitator ESP is used in the thermal power plant for removal of fly ash from the flue gas because of the environmental laws. The presence of large quantities of the carbon in the gas can adversely affect the efficiency of the electrostatic precipitator. Electrostatic precipitation is a process in
