AutoTune system automates gas turbine combustion tuning to optimize the GT for maximum power and increased hardware life.


Automated GT Combustion Tuning

Combustion AutoTune System for all B/E/F-class Gas Turbines, and now also for aeroderivative LM machines.


Automated GT Combustion Tuning

Ansaldo Energia's AutoTune system automatically tunes engine operating parameters to maintain emissions and combustion dynamics within specified limits under varying ambient conditions, engine deterioration, and while using a range of natural gas or liquefied natural gas. AutoTune also has optional software features to optimize unit operation from a power and heat rate standpoint. The result is improved emissions control, improved hardware life, and improved operability.


Optimize Unit Operation

The AutoTune system incorporates features which result in optimal operation from a power and heat rate standpoint. The result is improved emissions control, hardware life, reliability and operability.


Optional Software Components

Extended Turndown, Fuel gas temperature optimization, Power+ for maximum power, and optimization for LNG are all options for allowing optimal power and increasing hardware life.



Operators can select the Power+ option to have AutoTune maximize power output while maintaining emissions and dynamics within limits. Enabling Power+ takes advantage of existing NOx and dynamics margin, especially during the summer months, resulting in maximum power.


Key Benefits

The AutoTune system enhances gas turbine operability to meet today's energy market demands.

  • Eliminates need for seasonal manual tuning
  • Reduces risk of Lean Blowout (LBO) unit trip events
  • Improves emissions control year round
  • Extends hardware life with minimized combustion dynamics
  • Improves operability during changes in gas properties (e.g. Wobbe Index variation)
  • Improves turndown
  • Power+ option improves power output



Currently we have installed over 55 AutoTune systems worldwide.
