Ansaldo Gas turbin AE94.3A

Ansaldo Energia’s great operational flexibility which means they can be started up quickly in order to meet these needs turbines have cumulated over 4 million equivalent operating hours worldwide. They are a well-established solution with applications for baseload and peak, suitable for both Combined and Simple Cycle plants.
Both the hardware and the control system offer advanced self-adjustment capability.

• They can easily adapt to the chemical composition of natural gas and different gas blends.
• They can burn hydrogen up to 40% (as proven by >250,000 EOH of cumulated field experience), reverting at any moment to 100% CH4 for safe backup operation.

With the addition of our Autotune (a digital system that automatically tunes the engine to actual ambient conditions), they always run at the edge of their performances

The AirFlex Compressor Upgrade, based on Ansaldo-proven technology, is designed to increase flexibility in operation and maintenance, with an improved power output due to higher air mass flow.

Its light scope of work, with a reduced outage time, make the AirFlex a cost-effective upgrade.

The AirFlex Compressor Upgrade can be installed with the MXL2 upgrade to reach the maximum performance gain

 Your Gas Turbine

The new AirFlex Compressor Upgrade is applicable up to AE/V 94.3A Rating 2010 and up to SGT5- 4000F Version 7. It is fully compatible with MXL and MXL2. The implementation can be performed during an extended hot gas path inspection

Standard Scope

• Fully retrofittable, limited impact on standard outage scope: no rotor and casing parts rework

or replacement

• Reduced outage time since the new parts can be replaced without the rotor unstacking

• Compressor B&V: 3D aerodynamic redesign of first 6 stages with new blades and vanes

• Front and mid-section vanes improved design for highly flexible operation due to increased

part robustness and lifetime

• Blow-off system upgrade: line rerouting to match the new compressor operational parameters
