  • Shrink tunnel for shrinking shrink films on 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 flow 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 object of the invention is to provide a burner with which large amounts of air can be heated energetically favorable.
