... hydrogen fuel momentum swirl stabilized burner flame stabilization To a large extent, the development of gas turbine combustors is driven by the reduction of the nitrogen oxide (NO x ) emissions in the entire load range. This requires the improvement of the fuel-air mixing in the burner at high...

... dynamics of swirl burners designed for lowly reactive gases in a favorable way for proper flame stabilization of highly reactive fuels without changing the hardware geometry. The investigations presented in this paper cover the development of the optimum basic aerodynamics of the burner...

... imaging were applied to natural gas/air flames for a qualitative analysis of the position and shape of the flame brush, the flame front and the stabilization mechanism. The results exhibit two different ways of flame stabilization, a conical more stable flame and a pulsating opened flame. For quantitative...
