Abstract:

Abstract:The steam seal of the steam turbine of unit No. 4 in Jiangsu Huaiyin Power Generation Company Limited was reformed. In order to ensure the steam seal reformation effect,the
influence of the steam seal clearance on the system vibration wasanalyzed. The vibration control measures during unit acceleration and operation were proposed, which can be used as reference for similar units.
