An electrostatic precipitator as a function of the corona power ratio which is power consumed in watts divided by the airflow in cubic feet per minute cfm principle electrodes at high voltage create a corona effect ionized atmosphere surrounding them this charges the passing particles
However compare to bag filter esp is very economical let see entire study about electrostatic precipitator working principle of electro static precipitator it is working under principle of ionization electrostatic precipitation is a method of dust collection that uses electrostatic forces and consists of discharge wires and collecting plates
Oct 02 2015 esp basic principles of electrostatic precipitator electrostat ic p recipitator principles electro static precipitator or esp is a globally used system for effective filtrationcontrol of particulate emission it is a filter that removes minute dust particles from factory exhausts esps can collect dust particles of size 01 to 10 micron
The particle separation process in the electrostatic precipitator is based on the principle of electrostatic separation electrons are emitted by a negatively charged ionising electrode and accelerated toward a positively charged collecting electrode the particles that flow through the filter are
This is the principle of electrostatic precipitation and electrostatic precipitator apply this principle on an industrial scale the particles collected on the collecting plates are removed by methods such as 1 dislodging by rapping the collecting plates 2 scraping off with a brush or 3 washing off with water and removing from a hopper
The basic principle of electrostatic precipitation is that gasborne particles are passed through an electric field where they are initially charged by means of a corona discharge charged particles are then deflected across the electric field and deposited on collecting electrodes
Electrostatic precipitator efficiency and reliability have improved steadily since the 1970s as a result of research and development programs sponsored by equipment manufacturers trade associations and the usepa operating principles in all types of electrostatic precipitators there are three basic steps to particulate matter
Gea has been building electrostatic precipitators for cleaning industrial process for over many years well over 12000 units have been supplied to firms all over the world being the air pollution control technology supplier of choice gea offers innovative system designs stateoftheart microprocessor controls and constantly upgrades and rebuild enhancement strategies for your specific
Dipak k sarkar in thermal power plant 2015 14223 basic properties of the gas and dust particles a precipitator is designed specifically for an ash produced by coal containing a certain amount of sulfur if coal with different sulfur content is burned the efficiency will vary a coal with lower sulfur content may give satisfactory separation when the fluegas temperature is increased
The coulomb force caused by the electric field causes the charged particles to be collected on the collecting plates and the gas is purified this is the principle of electrostatic precipitation and electrostatic precipitator applies this principle on an industrial scale
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 twopart article discussing esp operation and some of the available upgrades and modifications now available for new
Sep 25 2013 electrostatic precipitator esp working function 1 prepared by syokesh 2 elctrostatic principle an electrostatic precipitator esp is an device that removes dust particles from a flowing gas such as air using the force of an induced electrostatic attraction ie like charges repel unlike charges attract electrostatic precipitators are highly efficient filtration devices
The basic design of an electrostatic precipitator is a row of vertical wires followed by a stack of plates oriented vertically with a usual separation of 1 to 18 cm 77 the gas stream flows perpendicular to the wires and then passes through the stack of plates where a negative voltage of several thousand volts is applied between the wire and
The basic principle of the electrostatic precipitator is to use electric power to capture the dust in the flue gas which mainly includes the following four related physical processes 1 ionization of the gas 2 the charge of dust 3 the charged dust moves toward the electrode 4 capture of charged dust
The basic principle of an electrostatic precipitator esp is to ionise particles passing through it after which they are strongly attracted to a series of plates upon which they are trapped a typical esp is constructed with a row of thin wires which is followed by a stack
Basic principles of electrostatic precipitators electrostatic precipitators take into account the usage of electrical forces to attract particles within a gas that is incoming these particles are thereafter supplied with electrical charges through compelling them to pass by a region whereby ions which are gaseous in nature pass through

Oct 27 2020 the working principle of the electrostatic precipitator is quite simple it has two sets of electrodes one is positive and another is negative the negative electrodes are in the form of rod or wire mesh positive electrodes are in the form of plates the positive plates and negative electrodes are placed vertically in the electrostatic precipitator alternatively one after another
The working principle of the electrostatic precipitator is to use a highvoltage electric field to ionize the flue gas and the dust charge in the gas stream is separated from the gas flow by the electric field the negative electrode is made of a metal wire of different crosssectional shape called a
The principles at work in an electrostatic precipitator are essentially the same forces that hold balloons to the wall when you rub them on carpet or a shaggy sweater as you rub a balloon electrons break free the balloon then loses electrons and becomes positively charged while the carpet which gains electrons becomes negatively charged
