Claims

[Claim for Utility Model Registration] A combustion device in which a swirler is attached to the tip of a burner guide provided along the central axis of a burner throat section, the base of which is pivotally attached to the inner circumferential wall of the burner throat section, and the free end of which is on the swirler side. A plurality of frame members are arranged, and a heat-resistant sheet is stretched between adjacent frame members to form a hollow funnel whose throat diameter can be freely expanded and contracted, and the swirler is fixed angle blades, A combustion device characterized in that it is formed with a variable angle blade which is disposed on the outer circumferential side of the fixed angle blade and whose inclination angle is variable according to expansion/contraction of the throat diameter.
