Definitions

  • the invention relates to an insert for a device for igniting or burning of fuels, in particular a heating device according to the preamble of claim 1, such as one of the FR-A-1 370 708 is known.
  • the present invention relates to a device for igniting or Burning fuels, especially a heater according to the Preamble of claim 8, corresponding to FR-A-1 370 708.
  • Corresponding inserts or devices such as mixed ignition devices with an oil atomization device or a gas combustion device with a surrounding this oil atomization device or gas combustion device Pipe are well known.
  • the pipe in question points around its circumference extending annular constriction sections or widening sections. Based on this construction, the temperature distribution within the tube is that can also be referred to as a flame tube, based on the entire diameter, equal.
  • FR-A-1 370 708 describes an insert for a device for ignition or Burning fuels, in particular for a heating device, is known.
  • This known use is in the direction of fuel ejection, i.e. in the direction of the flame, provided with several sections that sit on a cylindrical base body. These sections are twisted to each other so that a swirl the gases occur within the associated burner. So this is known Use designed as a swirl body and is intended to swirl the gases within cause the burner to face inwards, which is why the twisted Sections or slats are provided. This is intended to ensure that the soot number can be reduced to near zero, while the No reduction in the nitrogen oxide content in the combustion gas or in the exhaust gas is addressed.
  • an insert or a device propose that when burning fuel to a lesser extent of nitrogen oxides in the combustion gas or in the exhaust gas.

  • the amount of air or oxygen required for complete and effective combustion is supplied, but over a range that is lengthened by technical means, so that the combustion range is extended.
  • the maximum temperatures that occur are reduced, and consequently the quantities of thermal nitrogen oxides (NO, NO x ) that occur can be reduced.
  • the sections should be in the fuel ejection direction Longitudinal direction of the fuel ejection device at least partially be of different lengths, the relevant sections preferably in Groups are essentially the same length. It has proven to be particularly advantageous proven if the respective sections are of equal length in two stages and thus be divided into two groups. If necessary, there could be more Groups, e.g. a third group or level of essentially the same Sections or fins may be provided, possibly with larger heating devices.
  • Leave groups or levels of different lengths with the relevant sections are also adjusted in that the sections are at least partially different are oriented far inwards or are curved inwards.
  • either the sections ending at the front can be Cylinder or the like can be combined or the rear sections can be summarized accordingly.
  • this training ensures that the air outlet flows be separated. Thereby, the air outlet flow passes through the least wide sections or lamellae extending to the front is produced, directed inwards and the air outlet flow through the most advanced slats is generated, is directed to the outside.
  • a particularly advantageous arrangement results from the fact that the extension or the ring on the radially inward edge of the respective sections is arranged.

  • baffle block is ensured that in A pressure increase in the area in front of the baffle plate and in the area behind the baffle plate a decrease in pressure occurs in connection with the invention leads to the combustion area further apart by the additional negative pressure, which is also suitable for the flame at a predetermined Point to keep the combustion area further apart is, whereby the maximum occurring temperatures are further reduced can, which can further reduce the generation of nitrogen oxides.
  • the bluff body can advantageously be in the fuel ejection direction or in The longitudinal direction of extension of the fuel ejection device extends cylindrical or conical or funnel-like, preferably widening Have range. In this way, the said negative pressure zone can be more pronounced, which leads to the flame in the area of the bluff or the Baffle plate is held.

This can be used to make further improvements, for example achieve that the bluff body around the substantially central opening if necessary has recesses connected to this central opening.
  • Inserts that are similar or equally designed are used.
  • One insert can surround the other insert or one insert of several other missions. It is also preferable if there are free spaces or channels between the individual inserts through which Combustion gas or combustion air can be supplied.
