Definitions

  • the invention relates to a fastening device for forced draft burners on heat generators, in particular on boilers, the forced draft burner being connected via a pivoting device to a flange fastened to the heat generator, through which the mixing tube of the burner projects into the combustion chamber in its installed position.
  • the immersion depth of the mixing tube in the combustion chamber must be variable for optimum firing control.
  • known burner designs have a clamping flange. This clamping flange is displaceable and lockable on the mixing tube of the burner and is screwed to the boiler door or a corresponding component of another heat generator. If the immersion depth of the mixing tube is to be changed, the locking flange on the mixing tube only has to be released and the burner moved inwards or outwards by the required amount. The new position is fixed on the mixing tube by locking the clamping flange.
  • a decisive disadvantage of this solution is that the burner is very difficult to handle during maintenance and repair of the mixing device, in particular in the case of larger and thus heavy burners and where space is limited, since the burner must be completely removed from the heat generator for this work.
  • variable immersion depths can only be achieved by means of mixing tubes of different lengths.
  • a fixed stop is provided on the burner housing as a counter-bearing for the flange attached to the heat generator, to which the burner strikes in the installed position.
  • the immersion depth is therefore determined by the fixed stop. If they are to be changed, the respective mixing tube must be replaced by a longer or shorter one.
  • the resulting variety of components is disadvantageous for storage. This also results in higher manufacturing costs.
  • the object of the present invention is therefore to provide a fastening device for forced draft burners on heat generators, in particular on boilers, which is both easy to maintain and repair and also allows a simple change in the immersion depth of the mixing tube.
  • the flange attached to the heat generator is designed as a clamping swivel flange, or as a conventional swivel flange, in the latter case a displaceable on the mixing tube of the forced-air burner. and adjustable stop arranged and the pivoting device is articulated either on the burner housing or on the stop.
  • a swivel flange 4 is screwed onto the boiler door 3.
  • an O-ring 10 is inserted as a seal.
  • the swivel flange 4 is connected by means of one or more swivel joint arms 5 to a swivel joint 7 fastened to the burner housing 6.
  • On the mixing tube 2 is a slidable stop ring 8, which is slotted and can be locked on the mixing tube 2 via a screw 9. Its position on the mixing tube 2 determines the immersion depth. In the installed position, the stop ring 8 strikes the swivel flange 4, as shown. It is screwed to this.
  • the screw connection between the stop ring 8 and the swivel flange 4 is only to be loosened.
  • the burner 1 can then be pulled out and pivoted sideways. In this position, the mixing tube 2 is easily removable, and the mixing device is then accessible for repair or maintenance work. Since the burner hangs on the boiler as a whole, work can be done well even in tight spaces.
  • the burner 1 is swiveled in and pushed in until the stop ring 8 strikes the swivel flange 4. This ensures that the previously set immersion depth of the mixing tube 2 is maintained.
  • the screw connection 9 is loosened, the stop ring 8 is correspondingly moved on the mixing tube 2 and then locked again.
  • the swivel joint 7 is not provided on the burner housing 6 but on the displaceable stop ring 8. This is also screwed to the swivel flange 4. For maintenance and repair work on the mixing device, this screw connection must be loosened and the burner 1 pulled out and swiveled to the side. It then also hangs on the boiler, specifically above the stop ring 8 attached to the mixing tube 2.
  • the mixing tube 2 is divided into two parts.
  • the division plane 13 lies in the installed position of the burner 1 from the tip of the mixing tube 2 in front of the stop ring 8. Both mixing tube sections are connected to one another via a bayonet catch. The front mixing tube section can be removed quickly and easily, leaving the mixing device exposed for the necessary work.
  • a double tube construction can also be used, in which case the stop ring 8 is seated on an outer tube which surrounds the actual mixing tube 2 and is correspondingly shorter than this. This possibility is not shown in the drawing.
  • FIG. 3 differs from that previously described in that the pivot flange 4 has been replaced by a clamp pivot flange 12 and the stop ring 8 has been eliminated.
  • the clamping swivel flange 12 is screwed to the boiler door 3 via straps provided on its circumference and is likewise connected via one or more swivel joint arms 5 to a swivel joint fastened to the burner housing 6.
  • This solution is also easy to maintain and allows the immersion depth of the mixing tube 2 to be varied. However, since there is no stop here, the immersion depth must be readjusted after each maintenance or repair on the mixing tube 2 or on the mixing device.
