In order to accelerate the achievement of the goals of "carbon peaking" and "carbon neutrality", a series of laws, regulations, and institutional documents on greenhouse gas control have been introduced by the country, local governments, and industries. Nitrous oxide (N2O), as a gas with strong greenhouse effects, has attracted increasing attention from researchers. This article summarizes the current research status of N2O at home and abroad, compares the N2O emissions of typical coal-fired boilers, analyzes the generation mechanism, influencing factors, suppression methods, and removal methods of N2O during the combustion process, explores N2O emission reduction strategies for coal-fired boilers, and provides suggestions. It is necessary to strengthen the formulation of N2O related standards, research and development of new technologies, and demonstration applications for coal-fired boilers. Further research is needed on the influencing factors of N2O, such as pressurized oxygen enrichment conditions and coal moisture content, to further improve the suppression and removal methods.
