Effect of alkali metals on NO reduction by NH3/H2 mixtures during high-alkali coal combustion

Key Points

• NO reduction efficiency increased with the presence of alkali metals in NH3/H2 mixtures during coal combustion, indicating enhanced reactions.
• The study shows that specific alkali metals significantly influence the reaction pathways for NO reduction, demonstrating distinct effects on combustion efficiency.
• Assessment using reaction pathway analysis across varying alkali metal concentrations highlights their role in reducing nitrogen oxides effectively.
• These findings suggest optimizing alkali metal use in coal combustion may lead to improved environmental outcomes by lowering NO emissions.
