Abstract

Abstract: Two adjustable movable blade type axial flow fans are configured in boiler of a power plant as primary air fan. Since they were put into operation, the stall fault occurred frequently, and this influenced on safe operation of the unit seriously. According to the experiment and adjustment of the primary air fans of the unit, the reasons of stall fault of the fans in practical operation were analyzed. From the angle of operation technical management, the prevention and treatment measures of fan stall fault were put forward, which can be used as reference for operators of similar fans in prevention and treatment of primary air fan stall fault.
