Abstract

The intricate process of nitrogen transformation during combustion is crucial for in both the generation and control of NOx emissions, underscoring its paramount significance in environmental protection. This study focuses on the phenomenon a secondary increase in NO during air-staged combustion, systematically analyzing and summarizing the formation, decomposition, and reduction mechanisms of N2O. An exhaustive review of the dynamic interconversion between N2O and NO reveals a detailed phenomenon governing their mutual transformation during air-staged combustion. The observed differences in N2O and NO emissions arise from the distinct variances in their reaction mechanisms, which are uniquely tailored to the specific conditions encountered. N2O is present in the high-temperature zone of pulverized coal combustion due to the conducive atmosphere in the main combustion and transition zones, the secondary increase in NO in the transition zone is attributed to the oxidation of N2O to NO under these specific conditions. However, the secondary increase in NO may be closely related to N2O during the air-stage combustion of natural gas, which needs to be further explored. This research serves as a valuable reference for newcomers to the field of NOx research.
