Abstract: A self-regenerative burner has a burner tile coupled to the head portion of the burner. The burner tile includes a fuel injection hole formed through the center of a body; intake/exhaust holes formed around the fuel injection hole; a mixing-preventing separation wall formed with respect to the fuel injection hole, the separation wall bisecting the intake/exhaust holes to prevent air movement between the intake/exhaust holes; and first and second combustion sections formed at both sides with respect to the separation wall, the first and second combustion sections acting to alternately perform main combustion and exhaust, respectively. The separation wall allows intake/exhaust flows in the two combustion sections to be separated from each other. Accordingly, a flame in the burner is stabilized and the combustion and exhaust performances of the burner are improved, leading to an improvement in the energy efficiency of the burner.
