Formation and Destruction of Nitric Oxide in NO Doped Premixed Flames of C₂H₄, C₂H₆, and C₃H₈ at Atmospheric Pressure

A study of the formation and destruction of NO in adiabatic laminar premixed flames of C2H4 + O2 + N2, C2H6 + O2 + N2, and C3H8 + O2 + N2 doped with NO (100 ppm in N2) in a range of equivalence ratios at atmospheric pressure is presented. The heat flux method was employed to measure adiabatic burning velocities of these flames. Nitric oxide concentrations in the post flame zone at 10, 15, and 20 mm above the burner surface were measured using...
