Pennar Industries has been making ESP components for the past 15 years. The components include Collecting Electrodes & Discharge Electrodes. These components are manufactured by cold roll forming and then finished by carrying out various post forming operations. The customers list includes ALSTOM, THERMAX, ACC and L&T. Pennar also exports these profiles as a global source of FL Smidth (Denmark) and Hamon Research-Cottrel (Belgium).

How an Electrostatic Precipitator Works :

Thermal Power Plants and Cement Plants produce exhaust gases that contain dust, fly ash (unburnt constituents), fumes (fine elemental particles such as cadmium, sulphur and lead) and mist (such as coal tar), which pollute the environment. The contaminants are removed from the gas stream by using an electrostatic precipitator.

Collecting electrodes Particles caught in the flow of gas move through a collector chamber or passageway containing sets of electrodes in the form of parallel plates, bundles of tubes, or simply the collector's inner walls. The plates, tubes or inner walls serve as grounded electrodes that act as particle collectors.

Discharge electrodes - They are insulated electrically from the rest of the chamber and are charged with high direct current. The electrical charge ionizes the suspended particles, causing them to move toward the collecting electrodes. Opposite high voltages (plus and minus) are charged on two plate grids. The positive grid charges the particles and the negative grid attracts (collects) them.

The collecting electrodes are vibrated to loosen the particles, which fall into hoppers for collection and disposal.
