Ansaldo Gas turbin AE64.3A

Scaled down by the well-proven AE94.3A technology, the Ansaldo Energia AE64.3A offers the same high reliability in a compact package.
The rotor construction with the internally air-cooled hot gas path and the uniform temperature distribution, due to the annular combustion chamber, ensure optimum balancing of the thermal flow. This results in easy operation, fast start-up/hot restart time and high grid support capability.
Gas pre-mix combustion extension offers high flexibility throughout the operating range, with easy transient management and reliable fuel change-over.
A wide selection of fuels, ranging from low-BTU natural gas to liquid fuels, are burnt in dry pre-mix mode with no water consumption, thus minimizing both layout size and operating cost.
The compact size allows the AE64.3A turbine to be used in applications ranging from power generation to the marine industry, and make it the ideal gas burner in Energy Transition Combined-Cycle plant

The mid-size flexible solution
The AE64.3A was the first annular gas turbine in the world to be operated in
gas premix mode across the entire load range, simplifying the management
of load rejection and all the transient modes in general. Thanks to its fast
start up capability and operational versatility, it is a flexible solution for many
applications: open cycle/peakers, base load plants, Combined Heat and Power
Plants, power/steam producer for petrochemical industries.
Special application
Thanks to its compact design, the AE64.3A is suitable for offshore applications,
providing a reliable solution for fast deployment of power generation systems
also in remote marine/fluvial areas.
Able to operate by burning hydrogen in natural gas blends, the AE64.3A is also a
valuable proposal for refineries, chemical plants or small /medium size
renewable parks

Environmentally sustainable
NOx level down to 15 ppm in dry gas mode and 75 ppm in dry oil mode (with
possibility to reach 60 ppm with small water amount).
