Fundamental Characteristics of Ammonia/Air Premixed Laminar Flames

Akihiro HayakawaTakashi GotoRentaro MimotoTaku KudoHideaki Kobayashi

Fundamental flame characteristics must be required for the design of ammonia fueled combustors. However, few studies of ammonia combustion have been conducted. In this study, fundamental ammonia/air premixed laminar flame characteristics, such as NO formation/reduction mechanisms and laminar burning velocity, were experimentally and numerically investigated. NO mole fraction in burned gas from ammonia/air premixed flames were investigated using a stainless-steel nozzle burner. Experiments were conducted at various equivalence ratios and pressures. As a result, NO mole fraction in burned gas reduced with the increase in equivalence ratio and pressure. Formation/reduction mechanisms of NO were numerically investigated. Laminar burning velocity and…
