In this study, the effect of corona discharge on the combustion phenomenon has been made clear. A homogeneous propane-air mixture was used and three equivalence ratios were tested. For generating the positive and negative corona discharge, a non-uniform electric field was applied to the combustion chamber by the needle to plane gap. One or five needle-shaped electrodes were used to change the corona discharge state. When the positive corona discharge was applied, the luminescence from corona with five-electrode was weak as compared with that of one-electrode. When the negative corona discharge was applied, the luminesence from corona and combustion were not affected by number of electrode. When the positive corona discharge was applied by low voltage, the combustion was improved in the case of one-electrode, but the index of combustion with one-electrode was almost equal to that of five-electrode when the high voltage was applied.
