Definitions

  • the present invention relates to a forced draft burner according to the preamble of the main claim or to a method for operating such a forced draft burner.
  • the figure shows a schematic cross-sectional view of an oil blowing burner.
  • a housing -1 forms a hollow cylinder with an interior 2, which is surrounded by a jacket 3 and has end faces 4 and 5 at both ends.
  • the end face 4 has an opening 7, which is coaxial to a central axis of symmetry 6, through which a nozzle block 8 extends, to which supply pipes 9 for oil and 10 for air are connected.
  • the line 9 is connected to an oil pump, not shown, the line 10 to an air blower, not shown.
  • the nozzle assembly 8 ends at a distance 11 from the end face 4 in the central interior 12 of a flame tube 13, which is the same if a cylinder forms with a jacket 14, one end face of which is aligned with the end face 4 and the other end face of which forms an orifice 15.
  • the flame tube is at a uniform distance from the housing 1, so that the interior 2 of the housing is divided by the flame tube into an outer annular space 16 and the actual interior 12. While the one end face 4 together forms the end face for both the flame tube and the housing body, the housing 1 with its end face 5 projects beyond the mouth 15 of the flame tube.
  • the flame tube 13 is thus overlapped by the housing over its entire jacket region and at the mouth 15, but not in the region of the end face 4, where the fuel / air supply takes place.
  • a radial connection 17 is provided for air conveyed by a blower, which flows along the direction of the arrows 18.
  • An ignition electrode 19 projects through the shells of both the housing and the flame tube into the interior 12 inside the flame tube 13.
  • the ignition electrode 19 is attached in a region which lies between the end face 4 and the air connector 17.
  • a plurality of rings 20 of air inlet openings 21, 22, 23 and 24 are provided in the jacket 14 of the flame tube 13, the individual air inlet openings belonging to a ring having different sizes.
  • the ring 20 of air inlet openings 21 facing the nozzle assembly 8 has the largest total passage area for air; this ring lies approximately at the level of the end of the nozzle stocks.
  • the second ring of air inlet openings 22 is, seen from the mouth of the nozzle block, behind the ignition electrode, but in front of the air nozzle 17.
  • the third ring 20 is located approximately at the height of the air nozzle 17, so that the plane of passage of the air inlet openings with the central axis 25 of the air connector 17 is aligned.
  • the fourth ring of air inlet openings 24 is located directly at the mouth 15 of the flame tube. While the air inlet openings 21 have the largest overall cross section, the air inlet openings 22 are provided with the smallest air passage cross section.
  • the air inlet openings 24 assigned to the mouth have an average passage cross section, while the cross section of the air inlet openings 23 lies between that of the air inlet openings 24 and that of the air inlet openings 22. Air enters through all air inlet openings 21 to 24 in accordance with the arrows 26 shown.
  • the annular space 16 continues between the flame tube and the inner casing of the housing via the mouth 15 of the flame tube; here the jacket 3 of the housing 1 has a recess 27 which forms a truncated cone.
  • the larger diameter 28 of the truncated cone faces the jacket 3 of the housing 1, the smaller diameter 29 of the truncated cone is smaller than the diameter of the flame tube and thus covers part of the mouth of the flame tube.
  • the cone is designed as a step cone, it has a step transition 30, at which the cone inclination changes, in the direction of the smaller diameter 29, the cone becomes more pointed.
  • the deflection point in the The area of the large diameter 28 is such that the cone forms an acute angle 31 with the housing 1.
