Claims

[Scope of utility model registration request]

A burner is arranged at the center of the nozzle, a swirler surrounding the burner is arranged at the outlet end of the burner, and a subthroat having a diameter larger than the outer diameter of the swirler is connected to the outer wall of the nozzle by means of a subthroat support. A swirler blocking ring is attached coaxially with the nozzle to the swirler, and a swirler blocking ring is movable in the axial direction of the nozzle toward the inlet side of the swirler.
furthermore, a sub-throat outer circumferential air passage blocking ring is provided coaxially with the sub-throat and the nozzle outer wall on the inlet side of the sub-throat outer circumferential air passage formed between the sub-throat and the nozzle outer wall, and is movable in the axial direction of the nozzle. A combustion device characterized in that it is provided coaxially with the subthroat.
