In this study, a novel combustion diagnostic system based on tunable diode laser absorption spectroscopy (TDLAS) is developed to measure the temperature in flames on a turbulent partly premixed burner. This system simulates harsh industrial combustion environment and enables in situ measurements of non-uniform temperature distributions in CO/CO2/H2-air flames. The effects of H2 addition (0, 4%, and 8%, v/v) in CO/CO2 gas flow on multi gas flames are investigated by this system. Two tunable continuous-waves near 1996 and 2004 nm are employed as the light sources of laser. The flame temperature distributions at several different locations along the axial direction at the burner centerline are reported. The results of measurements are also performed to describe the effects of H2 addition on flame lengths and stability.
