Definitions

  • the invention relates to a combustion device for heating oil and the like according to the preamble of the main claim.
  • a burner is held in a housing which is open on its front side, from which fuel emerges during operation of the combustion device. Combustion air continues to flow through the housing during operation of the combustion device. To mix the combustion air well To reach the fuel, a baffle plate is arranged between the flame opening of the housing and the burner from which the fuel emerges, which in turn usually has a central opening and several air gaps.
  • the housing wall at the flame opening is bent inwards in DE-GM 90 03 176.8.
  • this embodiment has the disadvantage that the distance between the baffle plate and the bent edge of the housing changes when the baffle plate is moved forwards and backwards together with the burner in order to set the combustion device to different heating outputs. This changes the flow conditions during flame formation and it soot accumulates under unfavorable circumstances.
  • the invention has for its object a u. To create the.
  • a particularly intensive swirling of combustion air and fuel in particular by a recirculation on the outside of the flame, a particularly efficient and low-pollutant combustion enables.
  • the combustion flame is to be kept particularly cool, so that the generation of NO x gases is drastically reduced.
  • This economical and environmentally compatible combustion should be guaranteed in all operating positions of the combustion device, ie at all possible distances of the baffle plate from the flame opening of the housing.
  • a combustion device for heating oil u there is a combustion device for heating oil u.
  • the swirl webs are arranged transversely to the flow direction of the fuel-air mixture on a wall which is attached to the baffle plate.
  • This arrangement of the swirl bars has the advantage that the distance from the flame root, which is located at the bottom of the baffle plate, to the swirl bars not changed, even if the baffle plate e.g. B. is shifted axially in the housing when the heating power changes. This ensures that the combustion conditions for the flame are always kept optimal and that the fuel is always swirled well with the combustion air.
  • the recirculation of combustion air in the lateral areas of the flame also lowers the temperature of the flame, so that the formation of toxic NO x gases is reduced.
  • the combustion device according to the invention can be adjusted over a wide range under optimal firing conditions, so that favorable firing conditions occur both at high and at particularly low heating loads.
  • a combustion device for heating oil and. Like. From a housing 1, which narrows conically in its front section. Located at the front end of the housing 1 there is a flame opening 2, from which the flames emerge during operation of the combustion device. Inside the housing 1 there is a holding device 6 which carries a burner (not shown) and an ignition device (not shown). On the holding device 6, a baffle plate 3 is fastened by means of supports 9, which has a central opening 4 and several air gaps. The baffle plate 3 has a wall 5 on its outer circumference, on which in turn passage openings 7 are arranged. The interior of the housing 1 is in contact with the outside air, inter alia, with the passage openings 7, as can be seen, inter alia, from FIG. 2. From this sectional view it is clear that the upper region of the wall 5 is fastened to the lower region of the wall 5 by means of webs 10.
  • the swirling webs are not arranged at the upper end of the wall 5, but further below. Furthermore, in contrast to FIG. 1, the passage openings 7 are located directly below the swirling webs 8.
  • combustion air is guided through the housing 1 in the direction of the flame opening 2 during operation of the combustion device.
  • Fuel emerges through the nozzle of a burner, not shown, which is held in the holding device 6 and mixes with the combustion air.
  • the combustion air flowing through the housing 1 passes through the central opening 4, through one or more air gaps within the baffle plate 3 and through the passage openings 7 into the area behind the baffle plate 3, in which the flame root is formed. Due to the different flow paths, the fuel-air mixture is thoroughly mixed. An additional mixing takes place through the intermingling webs 8, and a suction develops behind these. This suction effect has the effect that a recirculation is formed which leads further cool air quantities to the flame. As a result, the flame is cooled and, due to this lower temperature, considerably less NO x pollutants are formed than in devices which work with a hotter flame.
  • the holding device 6 together with the burner held therein and the baffle plate 3 can be moved axially back and forth in the housing 1.
  • the baffle plate 3 is moved forward in the direction of the flame opening 2, so that the through openings 7 are either completely or partially covered by the wall of the housing 1. As a result, the air flow through the passage openings 7 is partially or completely prevented. So that the passage openings 7 close completely when the baffle plate 3 is fully advanced, it is advantageous if the wall 5 of the baffle plate 3 lies closely against the inner wall of a specific area of the housing 1. In the In the figures shown, this area is located in the immediate area of the flame opening 2 behind the narrowing area of the housing 1.
  • baffle plate 3 shown in the drawings and the design of the wall 5 as a ring are merely exemplary embodiments, which of course can also be carried out in a different way.
  • the construction of the baffle plate 3 as a polygon is possible.
