| Abstract: | Causes of common failures frequently encountered during operation by axial-flow blowers of fossil power plants were analyzed,such as stalling and surging caused by growth of flow inlet angle and/or pipe resistance;blade ruptures caused by bad working conditions,poor quality of working medium and blade;high temperature of bearings caused by poor lubrication,insufficient cooling and abnormal working conditions;vibration caused by ash deposit and erosion on blade's nonworking face,or by the large inclination angles etc.Meanwhile countermeasures for handling above problems are proposed. |
