Reasons analysis and treatment method on the common faults of axial flow fan

Abstract

Abstract: The primary air forced draft fans of the boiler No.1 and No.2 of Huadian Baotou Power Generation Corporation Limited are axial flow fans with movable vanes; the air flow and the wind pressure of the fans can be adjusted by changing the dip angles of the movable vanes; so the fans have high efficiency and are adjustable under the load variation in large range. The reasons of the common faults of the axial flow forced draft fan were analyzed, and after the relevant treatment measures were adopted, the better effects have been obtained.

Key words: axial flow forced draft fan, movable blade, flow, wind pressure, opening, treatment method
