In 1948, White6 ascribed the detrimental effects of back corona in reducing the collection efficiency of an electrostatic pre- cipitator to a lowering of the sparkover potential and to the production of positive ions which decrease the efficiency of charging of suspended dust particles in a negative corona

Corona effect is also known as corona discharge and is caused due to the ionization of the fluid such as the surrounding air. This effect is usually observed in high voltage systems. Name the factors that affect the size of the precipitator

In this work, an emission reduction setup was developed that can reduce NO, HC, CO and smoke simultaneously. The emission reduction setup is based on the concept of an electrostatic precipitator (ESP) and plasma generation by corona discharge technique. Both diesel and waste cooking oil biodiesel (WCO) were separately used for the test

Apr 20, 2006 Experimental and theoretical studies were undertaken to investigate the particulatefree secondary flow interaction in the wire-type electrostatic precipitator. The secondary flow generated by the corona discharge is not negligible, and strong flow interactions

ELECTROSTATIC PRECIPITATION . 5.1 INTRODUCTION The electrostatic precipitator {ESP) uses electrical forces to capture either liquid or solid particles from a gas stream. The precipitator is classified as a high-efficiency collector, comparable to the fabric baghouse or gas-atomized {Venturi) scrubber•

The electrostatic precipitator is a highly efficient pollution control device. The precipitator imparts a negative charge to the particles in the air or gas stream. As the stream passes through a high-voltage, direct-current corona, the particles are attracted to the oppositely charged plates (or

Oct 21, 2013 The effect of humidity on the negative corona discharge of electrostatic precipitators was experimentally and numerically studied. The current-voltage characteristics of a wire-plate electrostatic precipitator was measured over a range of temperatures and relative humidities. The inception voltage and electric field were determined based on the streamer theory. A numerical

The effects of corona wire distribution on characteristics of electrostatic precipitators were numerically studied. The electric field, charge density and removal efficiency were discussed at various Sww/Swₚ (ratio of wire-wire length to wire-plate length). The electric field and charge density had an oscillating distribution on the

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
