Definitions

  • the invention relates to a device for burning contained in a media stream oxidizable pollutants.
  • the device consists of a combustion chamber as well as in these opening channels for the supply of the preheated media stream and Lines for the supply of gas or gas required for the combustion of pollutants vaporous fuel.
  • the channels for the media flow supply exist from axially parallel to each other via a combustion chamber front side in approximately uniform Distribution arranged nozzle, which the combustion chamber with a prechamber connect, the nozzles opening in the plane of the combustion chamber face.
  • a line for the fuel supply is arranged concentrically in each nozzle.
  • Such a device is known from EP 0 572 693 A1.
  • the one used in it Burner is provided with several concentrically arranged ring channels for feeding the oxygen-containing polluted media stream and the gaseous or vaporous Fuel in the combustion chamber.
  • the one loaded with pollutants The ring channel supplying media flow is provided with swirl blades and by one Surround fuel supply channel.
  • the known burner is particularly complex in the production and still limits the desired intensive mixing with the polluted medium and the fuel on ring zones.
  • a burner is known from GB-A-2 178 839, but in which Swirl principle is not realized. Instead, a hole emerges from the holes in a front panel Burner housing the media stream essentially linear. This is the fuel fed via a single centrally located line. The end of the feed line is closed, so that the fuel flow through four evenly over the Circumferentially distributed holes in the jacket of the supply line must emerge.
  • Burner should therefore have a single supply line for the fuel to one if possible lead intimate mixing with the media flow supplied through holes. The quality of the mixing in such training is naturally very inadequate. At most, it happens with the media flows that come from the fuel supply leak out adjacent holes, for an acceptable mix.
  • the invention is based, for a device of the initially described object
  • a combustion chamber with little effort can be produced and particularly intensive mixing even with large volume flows the medium loaded with the pollutants and the fuel directly allows when entering the combustion chamber, so that the mixing zone and shorten the residence time of the medium can be further reduced with the same burnout ratio.
  • a device in the preamble of the claim 1 mentioned type which according to the invention is the characteristic in its Features specified features.
  • the mixing zone is also an induced one
  • Burner are made smaller by the largest possible number Burner replaced, which are parallel to each other via a combustion chamber front side in even distribution are arranged.
  • the assigned to each burner unit Swirl blades cause a highly turbulent swirl of the rays, which causes the intimate Mixing of the medium with the respective burner flame optimized and consequently the thermal oxidation of the pollutants contained in the medium is accelerated.
  • Another advantage of the device according to the invention is the high flame stability the burner with variable volume flows.
  • the radial outflow direction of the fuel reduces the risk of the burner flames tearing off larger volume flows.
  • the swirl flow also almost leaves the volume flow independent flame pattern with a minimal combustion chamber penetration depth.
  • a combustion chamber face 1 is equipped with 19 individual burner units 2. These are arranged axially parallel close to each other and extend in the essentially over the entire surface of the combustion chamber face 1.
  • each individual burner unit comprises 2 a nozzle 3, in which a ring of swirl blades 4 is arranged.
  • a hub 5 is provided concentrically in the nozzle 3 and has an axial bore 6, start from the branch lines 7 formed by radial bores. From one of these opens on the vacuum side of a swirl vane 4 The line 8 connected to the bore 6 becomes the single burner unit 2 with fuel provided.
  • a media stream loaded with oxidizable pollutants is not shown Heat exchanger preheated and passed through the nozzle 3. Issue the swirl blades 4 the media flow an intense swirl. This creates a highly turbulent Flow field with an extremely short mixing zone.
  • the device according to the invention can be operated with relatively low flame temperatures, as a result of which the NO x formation in the media stream is reduced.
