Abstract

To improve the lean flammability limit and combustion stability of premixed methane flames, plasma can be applied. A flat flame burner has been made with a high voltage electrode in the surface, which creates a nanosecond micro-discharge plasma in the gas channels. With Raman spectroscopy it becomes possible to quantify rotational and vibrational temperatures, caused by the plasma, using a Boltzmann- and Treanor distribution for the scattered population. Measurement results with varying equivalence ratios and degrees of plasma are presented.
