Abstract

Most investigations on the implementation of flameless oxidation in gas turbines have been focused on the emissions aspects while the demonstration of the combustion acoustiCS improvement has been hardly ever addressed experimentally. The present experimental study provides insight into the differences of combustion generated noise between the conventional flame and flameless oxidation regimes. Results include noise levels measured in both combustion regimes, for different air-to-fuel ratios, and show an increased noise output in flame mode as compared to flameless oxidation. The paper also explains the acoustic precautions taken to allow comparison between cases.
