RISIncreasing Flashback Resistance in Lean Premixed Swirl Stabilized Hydrogen Combustion by Axial Air Injection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Since lean premixed combustion allows for fuelefficiency and low emissions, it is nowadays state of the art in stationary gas turbines. In the long term, it is also a promising approach for aero engines, when safety issues ...
Investigation of Lean Premixed Swirl Stabilized Hydrogen Burner With Axial Air Injection Using OH PLIF Imaging
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the context of lean premixed combustion, the prevention of upstream flame propagation in the premixing zone, referred to as flashback (FB), is a crucial challenge related to the application of hydrogen as a fuel for gas ...
Shockless Explosion Combustion: Experimental Investigation of a New Approximate Constant Volume Combustion Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Approximate constant volume combustion (aCVC) is a promising way to achieve a step change in the efficiency of gas turbines. This work investigates a recently proposed approach to implement aCVC in a gas turbine combustion ...
Automatized Experimental Combustor Development Using Adaptive Surrogate Model-Based Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Lean premixed combustion is the state-of-the-art technology to achieve ultra low NOx emissions in stationary gas turbines. However, lean premixed flames are susceptible to thermoacoustic instabilities, lean blowout, and ...
Influence of Pressure and Steam Dilution on NOx and CO Emissions in a Premixed Natural Gas Flame
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the current study, the influence of pressure and steam on the emission formation in a premixed natural gas flame is investigated at pressures between 1.5 bar and 9 bar. A premixed, swirlstabilized combustor is developed ...
