Mechanism study on the effects of Na/K hydroxides and chlorides on NO reduction by biomass volatiles reburning during high-alkali coal combustion

Key Points

• NO reduction occurs effectively through the interaction of biomass volatiles and high-alkali coal.
• Exposure to sodium and potassium hydroxides significantly enhances NO reduction, with chloride ions also playing a role.
• Observational analysis evaluated various conditions involving biomass volatiles for reduced emissions during combustion processes.
• Findings highlight potential pathways for emission control in coal combustion, indicating broader implications for environmental policy.
