Abrupt Stoppage of Turbine Rotor, Running on Barring after Major Overhauling
MetadataShow full item record
Case Study 15: This case study is about a typical experience where a steam turbine, which was running at 100 RPM on barring (turning) after overhaul, stopped abruptly and the rotor was found to be seized. The case study is about this incident and the external factors influencing the turbine rotor seizure, from 100 RPM to zero RPM in less than 5 seconds, its root cause and the rectification activities.
