This Electric Generating plant was originally commissioned by Fluor Engineering on behalf of California Electric Co. with the purchase and installation of two (2) 33,000 kW / 13.8 kVA General Electric Steam Turbine Generators. Each turbine generator was supplied operating steam from Dual Fuel (Oil/Gas) Combustion Engineering supplied Boilers with Peabody Burners. Allis-Chalmers and Westinghouse supplied much of the remaining Balance of Plant equipment including feed and circulating pumps, condensers and ancillary equipment.
Two (2) additional 44,000kW/13.8kVA steam turbine generators and another
independently
operated pair of Combustion Engineering Boilers were later installed alongside
the original plant in the
late 1950's. Again, each unit operates independently with respective systems,
controls, Combustion
Engineering Boilers, Peabody Burners, Allis-Chalmers and Westinghouse.
The generating plant with all equipment was shutdown in 2001 and is currently in
an active
decommissioning phase. The Southern California climate is well suited for the
long term storage of this
machinery with consistently low relative humidity.
Upon arrival onsite, the plant was visually inspected and all assets found in
good overall
condition. The turbine generators, at this time, had not been operated in excess
of ten years however
lubricants and fluids were maintained and a blanket of inert gas was preserved
at all times on the
generators.
For reporting purposes, pairs of two of kind turbine generators will be
represented: Units 1 & 2
and Units 3 & 4. All supporting data and document images included herein
were available at the site in
a well kept file storage facility. Heat Balance Flow Diagrams are included in
this document as
attachments “A” and “B”. Presumably more information is available
however due to project and time
constraints such supplementary information and data shall be committed to an
additional task at a later
time.
Unit’s 1 & 2
Turbine Generator Inspections Summary Unit’s 1 & 2 are of the same design; Single Flow
Condensing Steam Turbine with Hydrogen

======================================
Unit’s 3 & 4
Turbine Generator Inspections Summary Unit’s 3 & 4 are of the same design; Double Flow LP
Condensing Steam Turbines with Hydrogen Cooled Generators, both units are installed end to end
on an outdoor pedestal arrangement. The Turbines Generators Enclosures and Appearance Lagging is all
in very good condition with little corrosion if any near the structural foundation connections.
Visual inspection of the Double Flow Low Pressure Turbine (LP)
revealed very little water erosion on the turbine blades and the case, coupling and exhaust
hood were all found in good condition. The Control Valves are all in good condition with albeit a film
of surface corrosion is present on carbon steel components. The generator stator winding end turns and
field coils were visually inspected with an industrial Videoscope and no abnormal conditions were detected. Photos
