electrical sectionalization

Proper electrical sectionalization is important to achieve high collection efficiency in the ESP. Electrical sectionalization refers to the division of a precipitator into a number of different fields and cells, each powered by its own T-R set. ESPs should have at least three to four fields to attain a high collection efficiency. In addition, the greater the number of fields the better the chance that the ESP will achieve the designed collection efficiency. There should be approximately one T-R set for every 930 to 2970 m2 (10,000 to 30,000 ft2) of collection-plate area.
