Abstract: Abstract:Taking the 600MW direct aircooled unit as example, the reasons of abnormal fracture of axial flow fan blade in air cooling island were analyzed. The measures for preventing blade fracture were proposed, which can be used as reference for similar steam turbine in installation of axial flow fan blade in the air cooling island.
