2018 Baboo Troubleshooting Turbine Journal Bearing Vibration
This paper provides the basis for identifying and correcting turbine problem describes turbine front and rear journal bearing vibration problem and rectified in running plant by some modifications. The 31 CO2 compressor turbine tripped on dated 01/01/2018 & 9/01/18 on rear journal bearing RJB (406 A/B) vibration high. The event analysed and preventive action was taken by some minor modification in running plant, this vibration was occurred due possibility of carbon deposition on the bearing in carbonization process of lube oil at high temperature. The event studied and rectification done by shielded Oxygen through purging of Nitrogen in bearing and also gland steam temperature raised about 5-70C from saturation temperature.
