Industrial Electrostatic Precipitator. There are a number of factors that can affect the performance of an industrial electrostatic precipitator in terms of its dust collection efficiency. Dust has electrical resistivity properties: Dust collection efficiency is expected to be high in the area where there is normal resistance. Most aerosols fall under the category of normal electrical resistivity

The physical design of the precipitator can impact collection efficiencies in three primary ways: Airflow, Voltage Potential, and Corona Generation. 1) Airflow, as already discussed, can be too fast through the unit causing the re-entrainment of particles or the prevention of collection due to velocity head

Electrostatic precipitator (ESP) is the most widely used device for particulate emission control .ESP is a physical process by which particles suspended in gas stream are charged electrically ,and under the influence of electric field are separated from the gas stream .The precipitation system consists of charged collecting surfaces and a high

One of the subtle factors in resistivity is the effect of particle size on electrical characteristics. Where high moisture levels or optimum gas temperatures exist, poor collection results with fine particulate matter are not generally seen—of course, taking into consideration the higher performance require-ments of

The basic principle of an electrostatic precipitator (ESP) is to give particles an electrostatic charge and then put them in an electrostatic field that drives them to a collecting wall. A gas stream containing suspended particulates is allowed to pass between two electrodes electrically insulated from each other, and between which there is a considerable difference in electric potential

Electrostatic precipitator (ESP) remove the gas borne particulate matter and the mist (liquid droplets) from the flue gas stream due to the action of electrostatic forces. When the gas stream passes through an electric field, the particles become charged and are migrated to the oppositely charged electrode-commonly known as Collection electrodes on the surfaces of which a porous layer of dust builds up

Aug 03, 2019 Different Types of Electrostatic Precipitators. Plate; Dry; Wet, and; Tubular; Plate Type. In plate type, two plates or electrodes are arranged vertically through which these gases will be passed horizontally. Due to the principle of corona discharge, the dust particles will be attracted to the positive plate by the electrostatic attraction. Dry Type

Basics of Electrostatic Precipitator (ESP) Operation. 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

Electrostatic Precipitator can be defined as a type of air cleaner or filter that utilizes electric energy for removing the impurities, dust particles from the air. This is a commonly used device for controlling air pollution. Most of the industries, power stations generate fossil fuels in the process of electricity generation or manufacturing

Nov 05, 2020 Nov 05, 2020 How an electrostatic smoke precipitator works. Electrostatic smoke precipitators work by forcing dirty flue gas (the gas escaping from a smokestack) past two electrodes (electrical terminals), which take the form of metal wires, bars, or plates inside a pipe or smokestack. The first electrode is charged to a very high negative voltage.As the dirt particles move past it, they pick up

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

2.1.2 GasStream Factors Affecting Electrostatic Precipitation Several important gas stream and particulate properties dictate how well an ESP will collect a given particulate matter. They include particle size distribution, flow rate, and resistivity which is influenced by the chemical composition, density of the particulate, and process

Sep 22, 2016 Electrostatic precipitators: This electrical equipment was first introduced by Dr.F.G. Cottel in 1906 and was first economically used in 1937 for removal of dust and ash particles with the exhaust gases of thermal power plants. 2. PRINCIPLES OF ELECTROSTATIC PRECIPITATOR Electrostatic precipitation is a method of dust collection that uses
