Steam Whip Phenomenon in Steam turbine
Abstract
This case study is designed to outline how the high vibration issue was successfully diagnosed, the root cause for the high vibration found and correction actions recommended. The source of mentioned high vibration - sub synchronous excitations is steam induced instability – steam whip, detected in HP/LP turbine seals, closer to Drive End bearing. This turbine was initially equipped by Antiswirl packages. It was confirmed that this system is installed or operated not properly, non-original spare parts were installed during last overhaul.
