AE94.3A:                                     The proven value

The AE94.3A is the natural choice when the F class performance are required to match the high reliability at the lowest investment cost, ensured by a proven consolidated technology.

AE94.3A: The proven value

​​​​​​The  AE94.3A is suitable both for combined and simple cycle application. The proven design of all its components, 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 resulting in easy operation, fast start up / hot restart time and grid support capability.

Optimizations to reduce the minimum environmental load keeping at the same time the machine ready for grid support, quick and reliable fuel change over are available as well. 

As a result of fuel gas premix combustion extension from synchronization to base load, high flexibility is possible throughout the entire operating range, including all transient conditions.

A wide selection of fuels, ranging from hydrogen enriched natural gas to liquid fuel, are burnt in dry premix mode with no water consumption, thus minimizing the plant and operating cost and the layout area. 

With more than 2 million equivalent operating hours cumulated and more than 70 units in Ansaldo Energia fleet, the AE94.3A offers the most proven technology in the F class market.

The AE94.3A Customer's benefits include:

  • Fast start​, fast ramp and hot restart capabilities
  • High fuel flexibility with quick and dependable fuel switch over and dry mode operation for both gas and oil
