In the development of new gas turbines, low emissions and increased efficiency are two of the main goals. Modern gas turbines therefore rely on lean premixed combustion, which has the downside of potentially rendering the combustion process unstable. So-called thermoacoustic instabilities are high amplitude pressure fluctuations that can arise when pressure fluctuations and unsteady heat release of the flame are in constructive interference. These instabilities can deteriorate the efficiency as well as the emissions and can be the reason for fatigue failures.

Gas turbine engines with sequential combustion systems are characterized by high efficiency, specific work output, and load flexibility. Beyond that, pollutant emissions compliant with legislation, the prevention of thermoacoustic combustion instabilities, and fuel flexibility are crucial for an engine’s competitiveness in today’s power generation market.
