The world's most powerful combustion turbine-according to the manufacturers-completed no-load, full-speed testing late last year.
The 212-mw, 50-hz GE MS9001F gas turbine ("9F"), jointly manufactured by General Electric and Alsthom Turbines a Gaz (ATG) of France, was tested in November at GE's Greenville, S.C., manufacturing plant. ATG is a subsidiary of the European Gas Turbine Co.
This first unit tested was built at the Greenville plant. The second 9F is being built at ATG's facilities in Belfort, France, and will be field-tested this year.
The MS9001F is scaled up from GE's 150-mw, 60-hz MS7001F gas turbine.
TESTING
The MS9001F ran for 83.7 hr of testing with a total of 19 starts to rated speed. Tests included a complete cranking check for rubs and integrity; firing checks for ignition, crossfire, and combustion stability; and steady-state testing of performance points of 90%, 95%, 100%, and 105% of ISO-corrected speeds.
Tests also involved measurement of inlet air flow, heat rate, exhaust temperatures, compressor pressure ratio, and first-stage effective nozzle area.
A certification test run was completed, and preliminary results are satisfactory, stated GE. A post-test inspection revealed no problems, the company said.
The Greenville prototype unit is undergoing a complete disassembly for engineering inspection. Thereafter, it will be rebuilt to meet customer specifications and is expected to ship later this year.
FRENCH UNIT
The Belfort unit is being manufactured for the French utility, Electricite de France (EDF), for installation at its Gennevilliers site near Paris. There, it will provide peaking power for that urban grid.
The unit is scheduled for shipment to the site early this year, with installation to be completed and field testing started in the fall. Commercial operation is expected by December.
GE and ATG both produced hardware for the two units.
ATG supplied compressor blades and wheels, compressor stator blades, inlet guide vanes and inlet guide vane actuator components, turbine nozzles, and turbine shrouds. GE provided turbine rotors, buckets and wheels, combustion components, and Speedtronic Mark IV controls.
The 9F is a cold-end drive machine, facilitating combined-cycle applications by allowing the exhaust to be ducted directly into a heat-recovery steam-generator.
The unit has a heat rate of 10,542 kJ/kw-hr and a simple-cycle efficiency of 34.1% at ISO conditions. Exhaust temperature is 1,100 F. (583 C.), and combined-cycle efficiencies of more than 54% are expected, said GE.
