Issue Statement
- When T2 at ESR trips off, the turbine continues to spin much longer than expected. The is a concern that the turbine will be damaged if it does not stop spinning when the inlet valve is closed. On a few occasions, the turbine continued to spin (~500Hz) until the the plant was re-started.
Agenda and Notes
- What do we need to do to fix this problem.
- Is this really a problem (I think that this is a big problem)
- Why do we think this is a problem (Is bearing gas on during that time)
- Should we be doing something manually?
- Other questions that we need to make sure we have answered.
Action Items
- investigate bearing gas process at ESR
- Verify LVDT on turbine inlet valve
- Warm T2. Schedule. Dependent on transfer line.
- Check seating force of T2 inlet valve (require trip?) (verify proper operation)
- Can T2 be isolated to support troubleshooting without damaging turbine or stopping entire CBX?
- Develop plan to isolate CBX in the event T2 must be stopped, and/or CBX must be tripped.
- Verify that we have a spare.
- What is required to check seating force (operationally)?
- Create an alarm that will alert us when turbine inlet valves are closed and turbine speed is > 0.
- drink a beer
- Get the transfer line from CHL operational
- follow-up meeting ~1/20/2017.
- Contact Pete to begin information/data collection, vendors, contacts.
