dc.description.abstractAmmonia (NH3) has been considered as a promising alternative energy carrier for automobile engines and gas turbines due to its production from renewable sources using concepts such as power-to-gas. Knowledge of the combustion characteristics of NH3/air and the formation of pollutants, especially NOx and unburned NH3, at intermediate temperatures is crucially important to investigate. Detailed understanding of ammonia reaction mechanism is still lacking. The present study reports ignition delay times of NH3/air mixtures over a temperature range of 1100–1600 K, pressures of 20 and 40 bar, and equivalence ratios of 0.5, 1.0, and 2.0. The experimental results are compared to the literature mechanism of Mathieu and Petersen (2015) and reasonable agreement is observed. Detailed modeling for ammonia emissions is performed, and the NH3/air combustion is found to be potentially free from NOx and unburned NH3 at fuel-rich conditions.
dc.description.sponsorshipAll ignition delay experiments were carried out at King Abdullah University of Science and Technology (KAUST) (grant no. BAS/1/1300-01-01). The funding for this work was provided by the Office of Sponsored Research at KAUST. Fruitful discussions with Dr. Arnas Lucassen (PTB) and Dr. Olivier Mathieu (Texas A&M) are gratefully acknowledged.
