Definitions

  • the invention relates to a method for burning a liquid or powdered fuel by means of a burner, the fuel being atomized by a fluid and burned together with an oxygen-containing gas.
  • a liquid fuel such as heating oil can be fed to a nozzle without pressure or at low pressure and atomized with a fluid such as air, gas or steam when it emerges from the nozzle (injection atomization).
  • a fluid such as air, gas or steam when it emerges from the nozzle (injection atomization).
  • the oil mist is mixed with an oxygen-containing gas such as air or oxygen.
  • the oxygen-containing gas is fed to the flame around the actual atomizer.
  • the atomizing fluid is under pressure. For the operator of a burner with injection atomization, it is therefore necessary to use energy to produce steam or compressed air.
  • the invention has for its object to provide a method of the type described above, with which a liquid or solid, powdered fuel can be burned with the least possible noise.
  • This object is achieved in that the fuel is atomized outside of the nozzle by means of oxygen.
  • a fuel is atomized outside the nozzle, the fluid for atomizing the fuel being gaseous oxygen.
  • the mixture of fuel and oxygen produced in this way is subsequently burned with the supply of an oxygen-containing gas such as air or oxygen.
  • the method according to the invention effectively avoids disadvantages of previous methods.
  • the atomizing oxygen is under pressure as in known methods, but the pressure level is comparatively lower than, for example. with atomization in a toroidal burner.
  • the outer mixture enables simple flow guidance of the atomizing oxygen, so that the combustion process in the method according to the invention is considerably quieter than in known methods.
  • the ignition speed of the fuel-oxygen mixture is increased. Due to the higher ignition speed, the risk of the flame lifting off is considerably reduced and the flame stability is improved.
  • oxygen is used both for: atomizing the fuel and for the subsequent combustion, a practically nitrogen-free atmosphere is created.
  • the atomization of the fuel takes place particularly simply and safely if, according to a preferred embodiment of the method according to the invention, the fuel as a central jet and the oxygen for atomizing the fuel as a coaxial, conical hollow jet from the nozzle. be performed.
  • the fuel is given through a central inner tube of the burner.
  • the oxygen is conducted in an annular channel arranged concentrically to the inner tube.
  • the oxygen is deflected so that it leaves the spray nozzle in the form of a cone.
  • the cone apex lies outside the spray nozzle on the extended axis of the inner tube. The oxygen escapes at high speed to atomize the fuel.
  • the structure of the external mixing nozzle required for this flow guide is very simple, relatively inexpensive and not prone to repair, since it has practically no wearing parts. If necessary, however, an atomizing nozzle for the method according to the invention can be easily replaced.
  • the oxygen for atomizing the fuel is set into a rotating movement with respect to its flow direction before it leaves the burner. This measure increases the intensity of the atomization.
  • the length of the flame can be influenced by different twists. In special cases (to achieve a long flame), the atomizing oxygen can also not be swirled.
  • the oxygen required for the combustion can be supplied to the atomizing nozzle in the form of air, oxygen-enriched air or oxygen.
  • an additional tube is arranged coaxially to the outer tube 2 and at a distance from the atomizing nozzle. In the ring channel formed by the outer tube 2 and the additional tube, the oxygen flows to the nozzle end.
