CALCULATION AND ANALYSIS OF AN AXIAL FAN BLADES' ACCIDENT

The present paper is a typical example which combined the theoretical calculation with the engineer practice. An axial fan of coal fired boiler fail many times, it seriously effect the running of the power plant. After a detail calculation and analysis about the rotor, bearing system, shell and blade by means of finite element method, the author find the cause of the axial fan's failure, and give a useful suggestion.
