9F-7 Gas Turbine Highlights
>40 Percent Simple Cycle Efficiency
- Air-cooled technology
- Advanced 3D aerodynamic compressor with 14 stages
Full-Load Validation Prior to First Fire
- GE’s Greenville, South Carolina validation facility conducts the most thorough full-scale gas turbine validation in the world
- Proven materials ensure reliable and efficient operation
- Improved rotor cooling and sealing using near flow path seals and cover plates — over 50% more rotor life versus the industry for cyclic missions
- Allows on-site replacement of compressor and turbine blades
Extended Turndown of 30% Gas Turbine Load While Maintaining Emissions Guarantees
- Combustion system is an evolution of the current Dry Low NOx (DLN) 2.6+ pre-mix system
- Turndown of the combined cycle plant from baseload to 40%
GE’s 9F-7 gas turbine in the FlexEfficiency 50 Plant operating at ISO baseload conditions for 4,500 hours/year is architected to achieve a 1.0 point increase of combined cycle efficiency, consuming less fuel per MW of power generated.
A typical customer operating GE’s FlexEfficiency 50 Plant with a 9F-7 gas turbine† for an equivalent net plant output of 510 MW could achieve an annual fuel savings of 6.4 million cubic meters of natural gas, equivalent to the annual natural gas consumption of approximately 4,720 EU households.
A typical customer operating under these conditions for an equivalent net plant output of 510 MW could avoid the emissions of more than 10 metric tons of NOx and 12,700 metric tons of CO2 per year, equivalent to the CO2 emissions of more than 6,480 cars on EU roads.
