Abstract:

A premixed methaneair flat-flame burner is described. The burner was designed to have a central flame which can 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 cms 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 methaneair flame temperature. This burner will be used as a calibration tool in the development of CARS Coherent anti- Stokes Raman spectroscopy.
