Electrostatic Precipitator. Electrostatic Precipitator will be provide to two Boiler stack to control particulate matter emission as coal will be used as fuel in boiler. The unique feature of electrostatic precipitator is the separating force that is applied directly to the particles without the necessity of accelerating the entire gas as is done for all other particulate collection devices. This leads to an extremely low pressure loss for the collection of fine particles compared with that in any other type of collector.  Applying a high-voltage between discharge electrode and collecting electrode causes corona discharge to produce negative ions.  The electrically charged dust is attracted towards the collecting electrodes by an electrical force  The dust accumulated on the collecting electrode is removed and dropped into the hoppers by rapping (i.e impart a vibration or shock to the electrodes) and wet clearing (i.e. water spraying)  Collection of all types of dust, droplets  Collection in both wet and dry conditions  Collection of even sub-micron particles

Electrostatic Precipitator. The one existing coal-fired boiler is equipped with a new electrostatic precipitator, together with necessary controls, stairways, galleries, enclosures, ductwork and ash removal system. The precipitator is located south of the existing Unit 6 boiler and turbine room at grade. The precipitator is approximately 160’ wide, 47’ long and 36’ high and has an operating weight of 2,387,000 pounds. The Unit 6 boiler was equipped with an electrostatic precipitator (designed for 98% efficiency). The new precipitator was installed in series with the existing electrostatic precipitator. The design combined collection efficiency of the new and existing precipitators is 99.6%.
