GE Energy's wide range of flexible power generation applications for the 9FA gas turbine include simple cycle, combined cycle, and cogeneration in both cyclic and baseload operation using a wide range of fuels.

• Combined Cycle applications are common in today's power plants. The gas turbine generator produces electricity and captures the waste heat to make steam to generate additional electricity via a steam turbine. Today, 95% of the 9FA gas turbine fleet is operating in combined cycle mode.
• Cogeneration is the production of electricity and useful thermal energy simultaneously from a common fuel source. The rejected heat from industrial processes can be used to power an electric generator. Surplus heat from an electric generator can be used for industrial processes or for heating purposes.
• Integrated Gasification Combined Cycle (IGCC) is the production of electricity from combined cycle gas turbine power plant operating on synthesis gas (syngas) derived from gasification of coal or other fossil fuels. In this case, the 9FA gas turbine is configured as a 9F syngas turbine with GE's Multi-Nozzle Quiet Combustor (MNQC) for operation on syngas or high hydrogen fuels, enabling carbon capture and sequestration (CCS) or use of CO2 for enhanced oil recovery (EOR).
• Integrated Water and Power Plant (IWPP) is the co-production of electricity and water in a single plant. Potable water is generated using the thermal energy in the gas turbine exhaust to drive desalination.

GE's 9FA gas turbine is a 50 Hz product that typically operates in a traditional market, such as Western Europe (England, Italy, Spain, etc.). Over the past few years, the customer base for the 9FA gas turbine has expanded to new markets in Eastern Europe (Latvia, Lithuania), North Africa (Algeria, Egypt), the Middle East, South America (Chile, Argentina), and China. GE has shipped more than 200 9FA gas turbines with 8.1 million fired hours since November 2010.

The 9FA heavy duty gas turbine is aerodynamically scaled from 7FA gas turbine. It uses advanced aircraft engine technology in its design. Key advantages of the 9FA gas turbine include its fuel-flexible combustion system and high output performance.

• Dry Low NOx (DLN) 2.6+ combustor has five outer fuel nozzles with a single center fuel nozzle, which ensures a stable combustion across a wide range of operating conditions. The DLN 2.6 architecture also has an advanced fuel nozzle, called the swizzle, which combines the fuel injection gas ports into the swirler vanes all within the fuel nozzle body to provide a better mixed, more stable combustion zone. The DLN 2.6+ is able to maintain low NOx and CO emission levels while extending the load range available for operation.
• Eighteen-stage, axial flow compressor is designed with an ISO base pressure ratio of 17:1 and airflow of 203 kg/second. High strength, corrosion resistant stainless steel airfoil material is used on the first eight stages with the remaining airfoils made of steel alloy.
• Advanced controls - Model Based Control (MBC) - GE has developed industry leading, aviation-proven technology for advanced control of the gas turbine using detailed, thermodynamic models of the gas turbine and its sub-systems. By controlling the gas turbine using a real-time physics-based model, the overall performance, operability, and reliability of the gas turbine is increased. GE's  MBC methodology has been used for several years on the 7FA gas turbine product and was introduced on the 9FA gas turbine in 2009.

GE offers world-class project management services, such as project engineering, controls, global field operation, contract management, and sourcing. We are a leader in emission capabilities, providing our customers environmental permitting support. We also offer grid connectivity and compliance support from concept to project completion.

Financing solutions and support for the 9FA gas turbine are available from GE Capital Markets for all stages of the initial project phase-from acquisition to final negotiation. We also support regulatory advocacy.

GE Energy's Quality Management System is designed to satisfy ISO9001:2000 requirements. In particular:

• Rotor balancing and full-speed no-load test of the 9FA gas  turbine is usually performed in the factory before shipment.
• Test software is validated on the 9FA gas turbine control cubicles before shipment.
• Over speed test and full-load rejection tests are done at customer site.
• Performance, noise, and emission measurements are also performed in situ on the 9FA gas turbine.
