Abstract: Combustion is a key method for converting energy, historically relying on fossil fuels like coal and oil, which have significant drawbacks for sustainable development. Ammonia (NH 3 ) is highlighted as a viable hydrogen carrier with high hydrogen content, easy liquefaction, and better transportation characteristics compared to hydrogen. Despite its potential, ammonia combustion faces challenges such as NOx emissions and combustion performance, necessitating further research into its combustion dynamics. This systematic review is geared towards encapsulating the latest advancements in the research and development initiatives pertaining to ammonia fuel combustion, with a particular emphasis on elucidating the chemical kinetics and strategies for controlling nitrogen oxide emissions, and delineates the technical hurdles and prospective research avenues associated with ammonia combustion.
