An electrostatic precipitator is a device that uses electric charges to remove airborne impurities in solid droplet gaseous or liquid forms It functions as an air pollution control system effectively capturing pollutants from the exhaust of factories industrial processes and power plants without the need for traditional filters
The effect of the electrostatic precipitator on particles of the size fraction from to 10 μm had a significantly higher efficiency which reached a value of % The last smallest column representing the size fraction of particles above 10 μm was reduced by % using an electrostatic precipitator
A schematic of a traditional two stage ESP is shown in Fig fan not shown draws air and particles into the system Suspended particles are charged by the acquisition of ions and/or electrons that are generated through the corona discharging processes in the charger [4] As the charged particles pass through the collector the strong electric force causes the

The design of a point to plane electrostatic precipitator particle sampler was first described in 1964 Citation Morrow and Mercer 1964 and in 1981 the performance of an ESP of similar design was rigorously evaluated in a landmark article Citation Cheng et al 1981 Both of these works suggested that under ideal conditions the point to plane ESP could sample
The electrostatic precipitator removes particles from a gas stream by first charging the contaminants and then removing them using electrostatic forces [80] The basic construction of the electrostatic precipitator consists of a row of thin vertical rods and a stack of flat parallel metal plates with a spacing of 1 18 cm apart oriented as
gations on the nature of electrostatic forces and engineering development of electrostatic precipitators was included in the book by White [1] The characteristic properties of the electrostatic precipitator are 1 low pressure drop of the order of 100 to 1 000 N/m2; 2 high gas capacity 105 or 106 m /h are quite common;
The paper is dealing with the presentations of collecting efficiencies of electrostatic pre cipitators Whereas the total separation efficiency and effective migration rates respec tively bear some problems in interpretation and discussion an observation of the flux of locally precipitated dust should lead to more clarity and an improved insight of precipita tion because it is only based
