Streamer Corona Plasma Assisted Nonpremixed Flame Holding of a Propane Jet

A streamer corona discharge plasma was used to assist a propane-jet flame. The nonequilibrium plasma was produced by a 10k Hz sinusoidal power source. The experimental results shows that a streamer corona was generated between the flame edge and the nozzle, and the use of the streamer corona plasma discharge resulted in significant increase in flame stability.
