Abstract: Measurements of HCN in flat, fuel-rich premixed methane/air flames at atmospheric pressure are reported. Quartz-microprobe sampling followed by wavelength modulation absorption spectroscopy with second harmonic detection was used to obtain an overall measurement uncertainty of better than 20% for mole fractions HCN on the order of 10 ppm. The equivalence ratio, ϕ, was varied between 1.3 and 1.5, while the flame temperature was varied independently by changing the mass flux through the burner surface at consta…
