We are changing out 14K gallons of turbine oil during our maintenance outage and the issue of oil foaming keeps coming up for discussion. Does anyone have any experience with foaming being an issue or have you had no problems on startup? Were using Mobil 797 oil that will be clean and water free. The turbine is a GE 850MwE nuclear unit.
Clarification-We have not changed the oil yet-thats scheduled for next month. My management is concerned that during startup we will have an issue because someone heard that foaming is an issue-I'm trying to bring some facts and experience to the table to counter what I believe is a non-issue. rgf
