Flame stability and NOx pathways in ultra-lean NH3/H2 micro-combustion

Key Points

• Flame stability enhances under ultra-lean conditions, improving overall combustion efficiency.
• Key evidence shows that nitrogen oxides (NOx) emissions increase significantly in specific combustion pathways.
• Analysis of micro-combustion processes highlights the critical role of ultra-lean fuel mixtures in reducing pollutants.
• Understanding these pathways may enable the development of cleaner combustion technologies, with potential for broad application.
