Abstract
One object of the present invention is to provide a burner which can uniformly heat a wide area without decreasing the heat radiation even when the swing width of the flame self-oscillating is large, and the present invention provides a burner in which a main combustion fluid and a second combustion fluid are combusted by ejecting the main combustion fluid while self-oscillating from a central expanding ejection port () which expands towards a tip end and ejecting the second combustion fluid from a pair of side ejection ports (and) provided on both sides of the central expanding ejection port (), wherein a pair of the side ejection ports (and) are disposed symmetrically with respect to a central axis of the central expanding ejection port (), and the central expanding ejection port () and the side ejection ports (and) are provided such that an expanding angle α of the central expanding ejection port () and an angle β formed by the central axes of a pair of the side ejection ports (and) satisfy a relationship of −5°≤β≤α+15°.
