Abstract: NO x contributes to the formation of ozone, a major greenhouse gas, through photochemical reactions in the atmosphere, and also causes acid rains. Therefore, there is a growing demand for reducing nitrogen oxides. NO X is actively generated at fuel-lean and high temperatures. Therefore, combustion near the stoichiometry ratio and avoiding the peak combustion temperature are reduction methods. Moreover, NO X can be classified into fuel NO X , thermal NO X , and prompt NO X according to the cause and characteristics of their occurrence. Ongoing research is analyzing key reactions that contribute to the formation of NO X and simulating phenomena via numerical analysis research to seek reduction measures. Therefore, the significance of the detailed and consistent reaction mechanism is increasing. The Okafor mechanism simulates a granular combustion reaction of methane and ammonia and better simulates the effect of the radical-based species on the formation of NO X based on the GRI 3.0 mechanism and Tian mechanism. The present study aims to analyze the key reactions of NO X formation through Okafor mechanism in the laminar flame of methane, to analyze the effect of oxidant concentration and pre-heating temperature on NO X formation. Numerical analysis research based on Okafor mechanism is expected to be useful to analyze the phenomenological causes of NO X formation.
