GE 9FA Gas Turbine Generator Set Technical Data:
GE 9FA Gas Turbine Generator Set is one of the most advanced technology gas turbine generator, and one of the highest capacity gas turbine genset in the world.
Capacity: 255.6MW
Single cycle efficiency: 36.9%
Preliminary temperature: 1288 Celsius degrees, exhausted temperature: Celsius degrees.
Pressure ratio: 15.4
9FA GE gas Turbine body:
The 9FA GE gas turbine generator set's main body is composed of booster, combustion chamber, turbine, bearing, bearing box, rear and front support and turbine base. there are five chambers. the booster is of 18 stages, turbine of 3 stages, and pull type rotor.
The GE 9FA gas turbine generator set was licensed by GE to our Chinese famous producer of Harbin. And now it is under nationalization under cooperative efforts of GE and Harbin. All the main parts are from GE, and every turbine will be certified and test by GE or GE authorized technicians or parties.
In March,2003, HPEC signed Technology Transfer Agreement (TTA) of 9FA heavy-duty gas turbine with GE. GE has transferred all 9FA gas turbine manufacture
technology to HPEC except for components which are forbidden to export by American government.
