Abstract
A premixed methane/air flat-flame burner is described. The burner was designed to have a central flame which could be seeded with sodium, and an annular guard flame which ensured a flat temperature profile in the seeded region. The burner produced a well behaved flat flame for linear gas velocities of 20 to 30 cm/s and air to fuel ratios within 15% of stoichiometric. The temperature distribution in the flame was measured for a range of operating conditions using the sodium line-reversal technique. The temperatures measured were within the range 2000 - 2100 K, slightly lower than the adiabatic methane/air flame temperature. This burner will be used as a calibration tool in the development of CARS (Coherent anti-Stokes Raman spectroscopy).
