ELECTROSTATIC PRECIPITATION FUNDAMENTALS
The vast majority of Industrial Electrostatic Precipitators are of the dry type, though wet precipitators are gaining popularity. Dry Electrostatic Precipitators are often referred to as Dry ESP's or DESP's while the Wet Electrostatic Precipitators are referred to as Wet ESP's or WESP's.Regarding particulate removal, the surfaces in a Dry ESP are rapped or vibrated, and …

Electrostatic Precipitation
For high carbon ferrochrome furnaces, electrostatic precipitators are not, however, commonly used, mainly for the following reasons: (1) fineness and high resistivity of the dust from an electric arc furnace can limit the dust removal efficiency, (2) risk of explosion because of high voltage sparking if there is CO in the gas during startup, and (3) relatively high investment cost …
