Abstract

Abstract: The abnormal situation of the movableblade adjustment of the adjustable movableblade axial flow forced draft fan and primary air fan in a 600MW unit boiler at long time operation was introduced. The fault phenomenon of the movableblade adjustment mechanism was analyzed and treated, and the practical feasible preventive measures were summarized, which can be used as reference for similar fan operation.

Key words: adjustable movable-blade axial flow fan, hydraulic control system, adjustment of movable-blade, fault
