Abstract： Ammonia combustion and co-firing are of positive significance to replace fossil fuels for carbon-free and carbon-reduced combustion to achieve carbon peaking and carbon neutrality goals. Focusing on the applications of ammonia and blended ammonia as fuels in chemical industry, the present work elaborates on the issues of ammonia combustion and ammonia-based co-firing, including (i) the reaction path, reaction equation, and mechanism model; (ii) the main limiting factors including the effect of equivalent ratio, ammonia ratio, and initial temperature on flame propagation speed and flame temperature; (iii) the mathematical modeling and prediction performances of reactions, fluid flow, and energy transport; (iv) the generation and control of nitrogen oxides during the combustion process; (v) applications of ammonia co-firing technology. Finally, the future outlook is highlighted to advance the fundamentals and technologies of ammonia combustion and co-firing.

Keywords： ammonia combustion ammonia-based co-firing combustion mechanism process factor modeling approaches NO_x
