Effects of DC electric fields on burning velocity of methane-air premixed flame were investigated with a cylindrical flame burner with a earthed porous cylinder. The center electrode was mounted on the centerline of the porous cylinder, and the porous cylinder itself was used as the other electrode. The cylindrical flame was formed inside the porous cylinder, and the flame never deformed when electric fields were applied. Increase in flame radius was detected when the center electrode was over+7000V, and no change of the flame was detected when the center electrode was less than+7000V. When the center electrode was negative, no change of the flame was detected up to 9000V. Increase in flame radius with electric fields is considered to show increase in burning velocity because the flame radius at a fixed ejection velocity without electric field increases when the burning velocity of the premixed gas increases.
