Definitions

  • the invention relates to combustion devices, in particular combustion devices for solid fuel.
  • the secondary gases are supplied via nozzle tubes that over a plurality of lateral outlet openings the secondary gas in the primary flue gas discharge or directly in the afterburning chamber.
  • the nozzle tubes are usually made of steel, usually high-alloyed Stainless steel, because these nozzle tubes have a frequent and strong temperature change or non-compliant fuels and yet not too thick-walled to be formed.
  • the lining of the Combustion chamber and / or the space for the flue gas removal to Nachbrennraum mostly made of incombustible materials such as fireclay or silicon carbide (SiC), which are made as moldings and then fit the lining the housing of the heater, which also made of sheet steel, cast or Fireclay exists, represents.
  • grate bars are not as hollow material, but as solid rods with a comparatively large cross-section of, for example, more than 2 cm Diameter, in particular more than 3 cm in diameter, used, wherein the Grate bars also made of a steel-iron material, preferably of cast iron, preferably made of heat-resistant cast steel.
  • the nozzle tubes are located below this grate and not in contact with this rust, wherein the nozzle tubes preferably like the grate bars also horizontally, but viewed in the supervision of these run transversely to one optimum mixing of the flue gases discharged down through the grate to achieve.
  • this flue gas discharge is below the grate inclined side surfaces of the side linings tapering to Nachbrennraum out designed to a nozzle effect and thus a good mixing to achieve.
  • the nozzle tubes have a triangular or pentagonal or round cross-section with an upturned tip, and therefore can be made very easy, because they are open at both ends.
  • nozzle tubes are on the side of supplying the secondary air with a across all the nozzle tubes reaching distribution box, which usually also Made of sheet steel, not welded or otherwise firmly connected, but only the front side in corresponding passage openings of a wall plugged into this distribution box and lie with their other end on or in a corresponding part of the front lining of the flue gas discharge, which also made of non-combustible material (fireclay or SiC), on.
  • distribution box usually also Made of sheet steel, not welded or otherwise firmly connected, but only the front side in corresponding passage openings of a wall plugged into this distribution box and lie with their other end on or in a corresponding part of the front lining of the flue gas discharge, which also made of non-combustible material (fireclay or SiC), on.
  • Fig. 2 is mainly the area of the flue gas discharge 5 in its construction recognize, which is limited at the top by the combustion grate 2, on which the Wood 10 or other combustible material rests, and thus what the main combustion chamber. 3 represents. Below the flue gas outlet, the flue gases enter a Afterburning 4, in which the afterburning of these flue gases and their Removal takes place to the fireplace, which is no longer shown.
  • the combustion device is in a housing 11 of, for example Sheet steel arranged, from whose vertical side walls transverse walls free ending so far inward that on this the side liners 13 with their bottom can be put on, the free passage between the Side linings for the flue gases, however, through the transverse walls of the housing 11 is not obstructed.
  • the pockets 16 are also adapted to the cross-sectional shape of the grate bars 2a, b, preferably an L-shaped with the tip pointing down and above have rounded cross-section.
  • Preferably are - as in the supervision Fig. 1 to recognize - the pockets 16 at a smaller distance or each other partially overlapping arranged as the thickness of the grate bars 2a, b, c .. corresponds to the grate bars not only in a given but in one to be able to arrange stepwise selectable distance to each other, depending on the size the parts of the fuel.
  • the nozzle tubes 6 lie with their other, facing away from the frontal lining, End in the through holes of a wall of the over all nozzle tubes from one to the other side wall of the housing 11 preferably continuous, hollow distribution box 9 made of sheet steel, in the z. B. from an end face forth in an access opening 19, the desired secondary gas is supplied and from there into the open end faces of the projecting into the distribution box 9 Nozzle pipes flows in. From there it will be on both long edges the nozzle tubes 6 existing outlet openings 7a, b passed and flows out this in the flue gas discharge 5 of the primary flue gas. An outflow through the opposite, lining-side open face of the Nozzle pipes are almost completely avoided by placing them with their front end abut the housing wall on the inside
  • the outlet openings 7a, b are on the two sides of the nozzle tubes, the one Cross-section in the form of an upright with the top pointing upwards Diamonds possess, at the two opposite and at the furthest apart points of the cross section and arranged in Longitudinal direction of the nozzle tubes 6 offset from each other so that in the region of Outlet opening z. B. 7a on one side on the opposite side just a gap between two outlet openings 7b is present.
  • the gaps are preferably about as long as the outlet openings in the direction of extension the nozzle tubes 6.
  • a nose 12 for example, be bent down, then in a corresponding Recess 18 in z. B. engages the lower end-lining part 14. Thereby a movement of the nozzle tube 6 in the direction of the distribution box 9 is avoided. Also, the nose 12 and the corresponding recess 18 in the lower Stirnausient 14 of the end face set back in the middle of the Stirnaus mecanicsers 14 be present as a blind hole or slot, creating a Movement in both directions is prevented, even if the nozzle tube in Distance in front of the housing wall ends.
  • Fig. 1 shows that the nozzle tubes 6 only as small as possible in the interior of the distribution box 9 protrude to disassemble the nozzle tubes in Wear case does not have to remove the complete distribution box, but - after lifting the grate bars 2a and the upper end lining 15 - slightly raise the nozzle tubes 6 at the liner-side end and then to be able to pull out of the distribution box 9.
