where η(r) is the graded PM removal efficiency; E a ⋅ E p ⋅ S is defined as the electric PM removal index, which represents the electric field energy density obtained by the flue gas volume in the unit PM collection area; α is the operation condition coefficient of the electrostatic precipitator, (cm/kV) 2 m/s; β is the system operating condition coefficient; E a is the average electric field strength of the electrostatic precipitator
----- Abstract This manual assists engineers in using a computer program, the ESPVI 4.0W, that models all elements of an electrostatic precipitator (ESP). Once an ESP is accurately modeled, the model can be used as an analytical tool to diagnose problems and to suggest ways to improve efficiency.
It has been anticipated that the overall precipitation efficiency of the elec- trostatic precipitator ~/is the ratio between the overall weight of the precipi- tated dust Wp and the total weight
2.1 BASIC THEORY AND PRINCIPLES OF ELECTROSTATIC PRECIPITATION 2.1,1 Operating Principles The basic principles of the electrostatic precipitation process are 1) development of a high-voltage direct current that is used to electrically charge (transfer to) particles in the gas stream (almost all commercial ESP's have negative polarity), 2) development of an electric field in the space between

Electrostatic precipitator, also called electrostatic air cleaner, a device that uses an electric charge to remove certain impurities—either solid particles or liquid droplets—from air or other gases in smokestacks and other flues. The precipitator functions by applying energy only to the particulate matter being collected, without significantly impeding the flow of gases.

Designers usually calculate a hypothetical average value for gas velocity from the gas flow and the cross section of the precipitator, ignoring the localized variances within the precipitator. New design and research and development are also discussed briefly. 2.2.1 Dry ESP's The major distinction between different types of dry ESP's is the

9/18/2020· For that reason, a new approach is being taken that uses threshold values for voltage and current to define the effective operation of the precipitator.Regardless of the choice of monitoring methodology, it is important to know the times at which the combustion plant is operated. The operation of the ESP must then be measured at these times.
Electrostatic precipitators use electric forces to remove pollutant particles from smoke, in particular in the smokestacks of coal-burning power plants. One form of precipitator consists of a vertical, hollow, metal cylinder with a thin wire, insulated from the cylinder, running along its axis (Fig. P23.67).
