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: Estimating nonvolatile particulate matter (nvPM)—or black carbon—emissions during an aircraft mission is extremely challenging because of the lack of reliable data in flight. For this reason, a detailed study has been ...
