F CLASS GAS TURBINES


Maximum Reliability
With millions of hours of operation, F class turbines have established GE as the clear industry leader for successful fired hours in advanced technology gas turbines. Representing the world's largest, most experienced fleet of highly efficient gas turbines, designed for maximum reliability and efficiency with low life cycle costs, GE's F class turbines are favored by both power generators and industrial cogenerators requiring large blocks of reliable power.
Introduced in 1987, GE's F class gas turbines resulted from a multi-year development program using technology advanced by GE Aircraft Engines and GE's Global Research Center. GE continually advances this technology by incrementally improving the F class product to attain ever higher combined cycle efficiencies.
GE's F class gas turbines offer flexibility in cycle configuration, fuel selection and site adaptation. All F class gas turbines include an 18-stage axial compressor and a three-stage turbine, and feature a cold-end drive and axial exhaust, which is beneficial for combined cycle arrangements where net efficiencies over 58 percent can be achieved
The available models of F Class are,
MS 9001 FA
MS 7001 FA
7FB
9FB

Maximum Reliability
From Argentina to Singapore, world power producers require reliable power generation. The 9FA is the 50 Hz gas turbine choice for large combined cycle applications.
Since the 9FA is an aerodynamic scale of the highly successful 7FA gas turbine, it too has experienced industry-leading reliability. Key advantages of the MS9001FA (9FA) gas turbine include its fuel-flexible combustion system and higher output performance.
The 9FA gas turbine is configured with the robust Dry Low NOx (DLN) 2.0+ combustor, which is ideally suited for the diverse fuels typical of the worldwide 50 Hz power generation market. The DLN 2.0+ combustor is the industry leader in pollution prevention for 50 Hz combined cycle applications, with greater than 56 percent efficiency and achieving less than 25 ppm NOx.
The 9FA is a building block that can be configured to meet site and power requirements. For re-powering applications where space limitation is a key consideration, the 9FA gas turbine can be configured in a single-shaft combined cycle arrangement with the generator and steam turbine. For large combined cycle or cogeneration power plants where flexible operation and maximum performance are the prime considerations, the 9FA can be arranged in a multi-shaft configuration where one or two gas turbines are combined with a single steam turbine to produce power blocks of 390 or 780 MW.
