Chemkin Analyzer.Distinguishing Thermal and Fuel NOx Contributions

      I am using the Chemkin Analyzer and would like to understand how Chemkin distinguishes between thermal-NO and non-thermal (fuel-NO) contributions when simulating the combustion of a nitrogen-containing fuel such as NH₃.

      Specifically:

      What is the criterion Chemkin uses to identify whether NO is formed via the thermal mechanism (Zeldovich) or from fuel-bound nitrogen?
      How can I determine, from the reaction pathway or flux analysis, whether the nitrogen in NO originates from the air (N₂) or from the fuel (NH₃)?

      Any guidance on how to interpret these contributions correctly within Chemkin would be greatly appreciated.

      Thank you!
