Analysis on Distribution Law of Damaged Filters for Bag Dedusters in Coal-Fired Power Plants

Abstract:

Operating for 1.5 years, part of filtering bags for bag dedusters in a coal-fired power plant had severely decreased intensity and were generally broken. These disabled bags were mainly at the middle and tail of dedusters. By analysis, the reason of the ineffectual filtering bags is oxidation corrosion and more flue gas passing through, owing to the nonuniform distribution of gas. As an improvement measure, such methods are needed as operation optimization, installing de-nitrification system and adding gas uniform plate in dedusters.
