Description
Robust overall design, rotor stiffness and excellent combustion stability (due to two external combustion chambers), make the Ansaldo Energia AE94.2 the right choice when fuel diversification and/or fast transient phases are required.
AE94.2 turbines offer fast start capability, extreme operation simplicity and superior fuel flexibility (2 minutes gas-to-oil and oil-to-gas fuel switchover).
They can be profitably used in simple or Combined Cycle, for base or peak load, when grid conditions are severe and in areas where power generation is based on alternative fuels.
The special AE94.2K version is specifically designed for burning low- and very low-BTU gases from steel mill or refinery processes.
The AE94.2s fleet is characterized by more than 20 years of successful operation and 6.6 million EOH, with an excellent record of robustness, operational flexibility and durability
 Fast and Flexible

The AE94.2 gas turbine is a benchmark for both operational and fuel flexibility.Its high cycling capability, combined with fast start up and high ramp rates, makes it suitable for peak plants, grid support and dead power grid energization as well.

Fuel diversification

For normal operation it is possible to use up to 40% of hydrogen in fuel gas blends, but the AE94.2 can burn also non conventional fuels (i.e. naphtha, crude and heavy fuel oil, hydrogen rich fuels, coal gases) as well liquid green fuels such as HVO, Methanol and Ethanol.Its special “version K”, specifically designed for low and very low BTU fuels, can manage a very wide range of syngas, well gases, coal gases

 With more than 120 units installed worldwide and 9 millions of operating hours cumulative through different fuels and load regimes, the AE94.2 shows excellent record of robustness, operational reliability and durability.Environmentally sustainable NOx level down to 15 ppm in dry gas mode and 75 ppm in dry oil mode (with possibility to reach 25 ppm with small water amount).

Smart maintenance approachCustomized service agreements, including upgrading packages, allow Customers to choose the best solution for their needs.

Extended 41 kEOH inspection interval for hot gas componentsPossibility to replace vanes and bladeswith rotor in placeImmediate accessibility into the combustion chambers for checks and repairs
