Ducon Wet Electrostatic Precipitator (WESP) are available in both horizontal & vertical configuration and are designed to achieve zero opacity and over 99.9% removal efficiency on particles down to 0.01 micron in size (<0.5 mg/Nm3)with 0.5 w.c. pressure drop.
Particles passing through the precipitator are given a negative electrical charge by being forced to pass through a region, called a corona, in which the gas ions flow. Once the particle has been negatively charged, it is forced to the positively charged plate.

Features of Wet Electrostatic Precipitator Suitable for applications requiring a much higher degree of gas purity at outlet than can be readily achieved by dry type ESP. Using water in removing the collected dust, the wet type ESP can achieve high dust removal efficiency (down to 1 mg/m 3 N) without being affected by the high or low electrical
boiler desulfurization tower work principle. The main basic technological process of limestone-gypsum wet flue gas desulfurization is: after the boiler flue gas is dedusted by an electric precipitator and boosted by a booster fan and then cooled by a flue gas heat exchanger it …
The basic design of an electrostatic precipitator is a row of vertical wires followed by a stack of plates oriented vertically, with a usual separation of 1 to 18 cm. 77 The gas stream flows perpendicular to the wires and then passes through the stack of plates, where a negative voltage of several thousand volts is applied between the wire and the plate. If this voltage is high enough, an electric discharge ionizes the …
A precipitator is designed specifically for an ash produced by coal containing a certain amount of sulfur; if coal with different sulfur content is burned, the efficiency will vary. A coal with lower sulfur content may give satisfactory separation when the flue-gas temperature is increased.
