Interaction between a nonthermal plasma and a flame

Summary form only given, as follows. The interaction between nonthermal plasmas and flames has been experimentally investigated. Diffusion flames and dielectric barrier discharges (DBD) with a wire-cylinder type were considered. A burner consisted of a round type fuel nozzle and concentric coflow confinement. Since the burner was used as a plasma reactor at the same time, it was made of quartz tube. Along the centerline of the burner, a stainless steel wire of 1 min diameter was protruded as a high voltage electrode. Firstly, the effects of flames on electric discharges were investigated in terms of discharge onset voltages and delivered power to the reactor. As results, vigorous streamers were observed along with a flame owing to the elevated temperature.
