Abstract: An efficient approach for the detection of the acoustic damping of gas turbine combustors is the combination of spatially resolved finite element method (FEM) approaches based on the Helmholtz equation with low-order ...

Abstract: Premixed combustion is a common technology applied in modern gas turbine combustors to minimize nitrogen oxide emissions. However, early mixing of fuel and oxidizer opens up the possibility of flame flashback into the ...

Abstract: Multi-injector burner systems offer a high spatial-temporal mixture homogeneity due to their small size and thus have a high NOx emission reduction potential at increasing flame temperatures. This potential is reduced due ...

Abstract: Axial staging in premixed gas turbine combustors is a promising option for the increase in firing temperature without NOx penalty and for the improvement of turndown ratio, which is limited by the onset of COemissions. The ...

Abstract: Lean premixed singlestage combustion is state of the art for low pollution combustion in heavyduty gas turbines with gaseous fuels. The application of premixed jets in multistage combustion to lower nitric oxide emissions ...

Abstract: The reduction of full and part load emissions and the increase of the turndown ratio are important goals for gas turbine combustor development. Combustion techniques, which generate lower NOx emissions than unstaged premixed ...

Abstract: A new approach to calculate the mixture statistics in multiinjector burner (MIB) systems from a single injector database is presented in the paper. In such systems, the mixture quality is highly sensitive to the flowrate ...

Abstract: The reduction of pollution and noise emissions of modern aero engines represents a key concept to meet the requirements of the future air traffic. This requires an improvement in the understanding of combustion noise and ...
