Abstract

This paper reviews recent advancements in ammonia reaction mechanisms, focusing on essential combustion characteristics such as laminar burning velocity, ignition delay time, and NOx emissions. As a carbon-free fuel, ammonia is attracting growing interest as a potential alternative energy source. However, its slow combustion characteristics and high NOx emissions present considerable technical challenges. To address these issues, research has aimed at improving ammonia’s combustion properties, resulting in the development of various reaction mechanisms that enhance performance. This review evaluates these models’ predictive accuracy for NOx emissions, particularly under high-pressure conditions. Furthermore, the paper highlights future research directions for optimizing ammonia combustion models to support the development of low-emission gas turbine technologies.
