IMPROVED TURBINE OPERATION BY DRAINAGE OF STEAM SYSTEMS AND MONITORING OF VIBRATION

This paper reviews recent operational problems caused by water induction into propulsion turbines and the resulting heavy vibration. The phenomenon is described as an orbiting vibration of the turbine shaft. Analysis shows the conditions required to produce this result. The steam system is discussed with a view to reducing the opportunities for water induction and specific recommendations are made for improved drainage. A newly developed vibration monitoring system is described which can be used to reduce turbine speed when large vibration levels occur.
