AE94.2 Evo2 : Summary
Upgrade Scope (HW4, HW3 and HW5 upgrade packages)
New Ansaldo Energia 3D turbine blades and vanes,
New aerodynamic optimized 1-5 compressor stages,
Advanced coatings (BC & TBC) on mixing chamber and inner casing
Benefit
Evo2 Turbine inlet temperature fixed to 1090°CEvo2 Turbine inlet temperature fixed to 1090 C
+10.0% increased power output in Simple Cycle(*)
+8.0% increased power output in Combined cycle(**)8.0% increased power output in Combined cycle( )
more than +1.4pt% increased efficiency in Simple Cycle (Up to 4.0% higher exhaust mass flow provide more power output in case of existing combined cycle or combined cycle extension compared to HW4 package only)cycle or combined cycle extension compared to HW4 package only)
Maintenance Interval Extension @ 1075°C (41MAC for base load units)

Summary & Conclusion
Ansaldo Energia Upgrade present and future packages for AE94 2Ansaldo Energia Upgrade present and future packages for AE94.2 have been presented.
All upgrade packages are modular, can be combined and are completely retrofitable.
Extended maintenance interval MAC41 up to 1075°C ISO (by HW2 HW4 d HW3 k )or HW4 and HW3 packages).
Decreasing combustion emissions by new VeLoNoxTM low NOx Burner (15ppm for methane firing units)Burner (15ppm for methane firing units).
