Corona effect in electrostatic precipitator

Update date: May 24

Corona Discharge Characteristics in Electrostatic Precipitator under High Temperature. Harmful substances like particulate matter (PM), nitrogen oxides and sulfur compounds emitted from marine diesel engine exhaust have a great impact on the air environment. Among them, especially black carbon in PM has a negative effect on global warming

    The suppression of corona by particle space-charge is of considerable importance in electrostatic precipitators dealing with medium to high concentrations of particulates. In addition to the expected reduction in corona current due to low mobility dust particles, the presence of these charged particles has two other main effects: 1

    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
