An electrostatic precipitator (ESP) is a filtration device that removes fine particles, like dust and smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding the flow of gases through the unit. In contrast to wet scrubbers which apply energy directly to the flowing fluid medium, an ESP applies energy only to the particulate matter being collected and therefore is very efficient in its consumption of energy (in the form of electricity).
ESP's are designed for high efficiency to maintain emission levels below 50 mg/nm3. Rigid pipe/and spike discharge electrodes are made from deep drawn CRCA tubes, ensuring longer life by preventing breakage/snapping. They ensure minimum arcking and allow considerable. Elevated voltage resulting in higher efficiency of ESP. Collecting plates made from CRCA sheets of 1.2 or 1.6 mm thickness have structural rigidity to maintain consistent electrode spacing which is very essential for performance of ESP's at high efficiency. Casing hoppers, etc are designed and manufactured and are fully leak proof thus containing the ingress of false air. This eliminates the corrosion of components long term performance of ESP. Microprocessor based TR sets, control panels ensure maximum power input into ESP to maintain high efficiency of ESP in all operating conditions.
