Definitions

  • the invention relates to a burner unit according to the preamble of claim 1 and a distributor unit for heating gas according to claim 10.
  • Shrink tunnels for shrinking shrink films onto products e.g. on packaging units, for example, to form containers from a plurality of individual packaging or packaging units are known.
  • the shrinking takes place here by a hot air or hot gas stream, which is hereinafter referred to as shrinkage gas flow and, for example, laterally applied to the respective, already wrapped with the shrink film packaging unit to shrink the shrink film on the packaging unit.
  • shrink gas stream is also directed to the underside of the shrink wrap wrapped product to seal the overlapping ends of the shrink wrap there, i. to be welded or glued.
  • the shrink gas stream is provided by a hot gas or shrink gas heater having at least one heater which is operated, for example, electrically or with a gaseous or liquid fuel.
  • the hot gas heater has a burner which is designed for burning the gaseous or liquid fuel with an open flame and acts in a separate from the shrinkage gas flow inside a combustion chamber, which emits the heat energy to the shrink gas flow in the manner of a heat exchanger.
  • pore burners for example in the form of gas burners, in which a flameless, volumetric combustion (glowing foam) takes place in at least one reactor, which consists of one or more pore bodies.
  • a disadvantage is the use of known pore burners, if so large volume flows are to be heated, since with large channel cross sections no sufficient radiation depth is reached or there is local overheating.
  • the shrink gas stream is provided by a hot gas or shrink gas heater having at least one heater which is operated, for example, electrically or with a gaseous or liquid fuel.
  • the hot gas heater has a burner, which is designed for burning the gaseous or liquid fuel with an open flame and acts in a separate from the shrink gas flow inside a combustion chamber, which emits the heat energy to the shrink gas flow in the manner of a heat exchanger,
  • Such Device was, for example, by the JP 53,016,990 presented.
  • Such a pore burner was, for example, by the EP 1 729 063 A1 presented. Although this document is concerned with increasing the economics of pore or gas burning, this document does not suggest to improve the mixing of the hot gas leaving the burner with the significantly cooler fresh air.
  • a device for the arrangement of a possible smooth outflow of the hot gas from the housing of a pore burner was by the US 5,814,789 presented. Again, this document makes no suggestions that lead to improved mixing of the hot gas with the fresh air.
  • the object of the invention is to show a burner with which large amounts of air can be heated energetically favorable.
  • a burner unit according to the patent claim 1 is formed.
  • a gas distribution unit according to claim 10 is also included in the invention, such as the use of the burner unit and / or the gas distribution unit for a shrink tunnel or a shrinkage process.
  • burner unit 1 comprises a fan 2 and unspecified suction openings and leads, a hood-like burner head 3, in which the cuboid pore element 4 is held.
  • This pore element or pore block 4 has a gas inlet side 4.1 and a gas outlet side 4.2.
  • the burner head 3 has a peripheral flange region 5, with which the burner unit 1 on a flow channel 6.
  • FIG. 2 shows in a perspective view, the collection and outlet element 7 alone.
  • This has a hood-like or roof-like body 8, on the longitudinal sides of fastening strip 9 are formed to secure the collecting and outlet element 7 on the burner head 3.
  • Openings are provided on two planes A and B, the planes being at a distance C from each other.
  • On the plane A, 8 are directly in the body 8 six openings introduced, of which three openings open in a blank 10, which can discharge gas through the openings 11 on the B level.
  • the openings 12 lead through the wall of the main body 8 from the collecting and outlet element 7 out.
  • the perpendiculars 13 on the three openings 11 and the perpendiculars 14 on the three openings 12 are arranged in the example shown in a common plane which is perpendicular to the planes A and B.
  • the dash-dotted lines indicate the direction of flow through the arrow.
  • Fig. 3 shows in a sectional view by way of example a distribution unit 15, on which the burner unit 1 according to the invention is arranged.
  • a distribution unit 15 On the input side 16 17 return gas from the schematically indicated shrink tunnel 18 is sucked through a plurality of channels. This is done via a compressor unit not shown in detail, which is arranged laterally on the distributor unit 15.
  • the recycled air or gas stream from the shrink tunnel 18, which has entered the distributor unit 15 at the input side 16 flows past the burner unit 1 and is mixed with hot fresh gas. This hot fresh gas exits from the openings of the collecting and outlet element 7, not shown.
  • the main flow direction in the distributor unit 15 is indicated by the arrow.
  • the main gas stream is thereby deflected in the direction of flow in the region of the burner unit 1 only downwards, through the ramp-like slope of the main body 8, then directly below the outlets on the two planes A and B (FIG. Fig. 2 ) is intensively mixed with hot fresh gas and heated and subsequently deflected downstream again by means of gas guide bodies 19 arranged at the bottom of the distributor unit 15. Downstream, the heated main gas flow is distributed on the outlet side 20 of the distributor unit 15 to a plurality of channels 21.
  • This device is characterized by the fact that it is very space-saving, all known uses energetic and procedural advantages of a pore burner compared to electric heating systems.
  • the pore base body itself has a relatively easy to produce, conventional cuboid shape and can be structurally easily mounted outside of the main gas stream in the distributor unit.
