7,500 kw general electric condensing automatic extraction steam turbine generator unit
Manufactured in 1949-50
Start-up date: early 1960s
Retirement date: 1993
The unit was in good operating condition when it was shut down due to plant decommissioning and was carefully removed from the original installation site.
Being a multi valve inlet and extraction unit, it operates more efficiently than a single valve unit at part load.
This steam turbine generator unit is offered loaded on trucks.
