Argus AIC, the innovative control system for active damping of self-excited combustion oscillations, also called thermoacoustic instabilities, pulsations or humming.
With our new product Argus AIC, we shall be offering a highly flexible control system for active damping of self-excited combustion oscillations which can be used in single-burner and multiple-burner arrangements as well as in land-based gas turbines. This innovative technology is based on the tried and tested AIC 300 system which is successfully in operation around the world in large land-based gas turbines of modern combined cycle (gas+steam turbine) power plants.

Areas of application:

• Industrial or land-based gas turbines.
• Large industrial firing systems, e.g. process gas heaters.
  

Main features:

• Analysis and recording of up to 16 sensor signals and control of up to 32 actuators.
• Automatic setting of control parameters.
• Modular design.
• Complete integration into the gas turbine control system by digital, analog or field bus interfaces, e.g. Profibus, Modbus, Can-Bus, etc.

Advantages in comparison to passive measures:

• Easy upgrade for existing applications.
• No cost and time intensive altering of the construction of the combustion system is necessary.
• The efficiency, stability and construction of the combustion system are not negatively affected - no additional losses occur due to the Argus AIC system.
• Pollutant emissions are even partially reduced, e.g. NOx and unburned fuel/gas.
• The control is able to adapt to the actual system behaviour and its changes.
