Study on Application and Issues of Bag Dedusters in Coal-Fired Power Plants

Abstract:

Article Preview

To meet the standard requirements of dust emission for boiler and ensure the safety and normal operation of desulfurization equipment, bag dust filtering technologies have been used widely to deal with flue gas. Because of design defects and different running conditions, abnormal breakage may appear in the key parts of the bags, particularly some issues such as oxidation and acidic corrosion of the bags may happen in short-term application of electrostatic-bag precipitators. This paper elaborates the status of bag filters in coal-fired power plants, discusses some issues of bag filtering technology in design, manufacture and operation, and especially analyses the special problems of composite electrostatic-bag precipitators. Solutions are presented for extending the life of filtering bags.
