Abstract :
The damage that occurs in the FD Fan is caused by high vibration which can endanger the device and interfere with the secondary air process (Secondary Air) which will be flowed into the boiler and the combustion air in the boiler furnace so that a repair process is needed, the repair used is overhoul, namely repair process to find the source of the high vibration, the magnitude of the vibration that occurs in bearings 1V O.34 mm/s, bearings 1H 0.43, bearings 1A 0.93, bearings 2V 0.62, bearings 2H 0.46, bearings 2A 0.53, so that you can plan any improvements course that is done on the FD Fan. The method used is by means of Balancing Impeller Fan so that the rotating object is balanced. After overhouling, the vibration values dropped on Bearing 1H 0.27 mm/s, bearing 1H 0.39 mm/s, bearing 1A 0.91 mm/s, bearing 2V 0.47 mm/s, bearing 2H 0.49 mm/s, bearing 2A 0.46 mm/s.
