In this study, quantitative nitric oxide concentration distributions are investigated in the laminar premixed CH_4/O_2/N_2 flames by laser-induced fluorescence (LIF). The measurements are taken in flames for different equivalence ratios varying from 0.8〜1.4, and flow rate is fixed as 5slpm. The NO A-X(0,0) vibrational band around 226 nm is excited using a XeCl excimer-pumped dye laser. Selecting an appropriate NO transition minimizes interference from Rayleigh scattering and O_2 fluorescence. NO concentration is rised when equivalence ratios increase at different vertical distances from nozzle tip. In any case, the maximum NO concentration reaches the maximum in reaction zone.
