Increasing 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 ...
