Proc. ASME. GT2022, Volume 2: Coal, Biomass, Hydrogen, and Alternative Fuels; Controls, Diagnostics, and Instrumentation; Steam Turbine, V002T03A008, June 13–17, 2022
Paper No: GT2022-81004
... for use in high-pressure systems. In the current study, the oxidation of ammonia/natural gas/hydrogen mixtures was carried out to study CO formation profiles as well as the ignition delay times behind reflected shock waves in order to refine chemical kinetic models. Experiments were carried out...

... temperature ranges. Considerable model disagreements have been shown at intermediate pressures (10–100 atm), while good agreement is seen for higher pressures (> 100 atm). Further examination of literature data highlights that the ignition delay time (IDT) characteristics of syngas at these pressures show...
