Dynamic lifted flame in centerbody burner

Proceedings of the Combustion Institute, 2011
Abstract During some exploratory experiments performed on a centerbody burner it was observed that the sooting behavior of the burner could be altered dramatically without changing the fluid dynamics. One of the interesting operating regimes, in which the flame lifts off and forms a column of soot, was identified when oxygen in the annular flow was ...

Stability of lifted flames in centerbody burner

Combustion and Flame, 2011
Abstract The centerbody burner was designed with the objective of understanding the coupled processes of formation, growth, and burn-off of soot through decoupling them using recirculation zones (RZs). Experimentally it was found that the sooting characteristics of the centerbody burner could be altered dramatically via simple changes in the ...

Ultrasonic stabilization of small lifted flames

The Journal of the Acoustical Society of America, 2003
Combustion of a fuel gas (such as methane) flowing at low speeds from a nozzle into air produces a flame commonly described as a ‘‘diffusion’’ flame. As the flow rate of fuel is increased, the flame is known to lift off the nozzle. This premixes fuel with air and improves certain aspects of the combustion.

The stabilization mechanism of lifted diffusion flames

Combustion and Flame, 1966
Abstract Measurements on gas composition, gas flow velocity, intensity and Eulerian scale of turbulence have been made in a free jet of methane emerging from a conventional circular burner into an unconfined atmosphere. From the experimental data it appears that the base of a lifted diffusion flame anchors in a region where a stoichiometric ...

Numerical Prediction of Flame Lift Off and NO Emissions for Hydrogen Air Flames

Volume 2: Coal, Biomass, Hydrogen & Alternative Fuels
Abstract Fossil fuel-based gas turbine engines contribute significantly to carbon dioxide (CO2) emissions, which can adversely impact the environment. Next-generation of gas turbine engine designs attempt to reduce CO2 emissions by improving the overall engine efficiency or via alternative fuels.
