The Effects of Non-Premixed Hydrogen on Soot Formation in an Ethylene-Fuelled Laboratory-Scale Rich-Quench-Lean Combustor

Abstract This work investigates the effects of hydrogen blending on soot formation and flame structure in a laboratory-scale Rich-Quench-Lean (RQL) burner using ethylene-hydrogen mixtures (0-50 vol.% hydrogen) at constant carbon mass flow rate. Laser-induced incandescence and sin...

Extinction Prediction and Emission Analysis of a Bluff-Body Stabilized Ammonia-Hydrogen-Nitrogen Premixed Flame With Conjugate Heat Transfer

Abstract Ammonia/hydrogen blends represent a promising carbon-free fuel for gas turbine combustors. To minimize the NOx emission, premixed ammonia/hydrogen/nitrogen flames under ultra lean equivalence ratios are investigated. This paper simulates the extinction process of a bluff...
