GE's new 9FB GT and 'FlexEfficiency 50' 510 MW single-shaft CCGT plant
Chris Hodrien
9FB Gas Turbine Highlights
>40 percent simple-cycle efficiency
- Air-cooled technology
- Advanced 3D aerodynamic-design compressor with 14 stages
Full load validation prior to first fire
- GE’s Greenville, South Carolina validation test facility conducts the most thorough full-scale gas turbine validation in the world.
Advanced technology
- Proven materials ensure reliable and efficient operation
- Improved rotor cooling and sealing using 'near-flow path' seals and cover plates — over 50 percent more rotor life versus industry for cyclic missions like windfarm balancing.
Field-replaceable blades
- Allows on-site replacement of compressor and turbine blades
Extended turndown of 30 percent 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 ratio of the combined cycle plant from baseload to 40 percent
GE’s new 9FB Gas Turbine† in the 'FlexEfficiency 50' CCGT plant operating at ISO baseload conditions for 4,500 hours per year is designed 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 new 9FB 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 510MW 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.
