Definitions

  • the invention relates to a boiler for the combustion of liquid or gaseous fuels according to the preamble of the main claim.
  • the longitudinal ribs which divide the ring-cylindrical heating gas flue into individual flues, can be provided in a variety of ways in the design of the combustion chamber. So it is known for the formation of the combustion chamber to produce this as an internally ribbed one-part or multi-part cast body. Furthermore, it is known to form the combustion chamber by means of extruded profiles, the longitudinal ribs of which are also formed during their manufacture.
  • Two other variants consist in the fact that appropriately adapted, internally ribbed cast rings are used in the cylindrical combustion chamber in a heat-conducting manner, or that a correspondingly large sheet metal blank is provided with a large number of folded longitudinal ribs, this blank is rounded cylindrical and inserted overall into the cylindrical combustion chamber and for a heat-conducting one Connection of the two layers ensures. Apart from that, you can of course also arrange angle profiles parallel to the axis and closely lined up on the inner wall of the combustion chamber.
  • the invention is therefore based on the object to improve heating boilers of the generic type and to find a compromise between "hot” and “cold” combustion chamber wall, ie to ensure from the boiler construction that there are no impermissibly high NOX values in the exhaust gas can adjust and with the proviso that the previous boiler design principle can be essentially maintained and also the combustion chamber in terms to optimally train their insertability and condensate-proof design.
  • the end edges of the longitudinal ribs are at least pre-machined so that all opposing rib end edges are at the same distance from one another, the combustion chamber divided into individual rings then being pushed in under compressed air to produce the thermal contact.
  • the division of the combustion chamber into at least two rings according to the invention is of particular importance, since it is easier to achieve the thermal contact in all areas than with a one-piece combustion chamber, individual rings are easier to insert by pressing in, no high demands have to be made on the processing of the longitudinal ribs and there is also the advantage for the condens area of the combustion chamber where there is a risk of satellites, condensate-proof material for the ring can only be used in this area.
  • heating boilers of the generic type are double-layered for reasons of condensate safety with regard to the partition between the combustion chamber and the water-carrying interior of the boiler housing, the inner layer consisting of a correspondingly folded sheet metal blank, which, as it were, is rounded and forms an internal insert.
  • folding the ribs it is inevitable because the folds at the foot of the ribs cannot be made sharp-edged, that between the inner layer and the actual combustion chamber wall, gusset gaps arise, in the area of which the heat transfer is substantially reduced.
  • the boiler consists of a water-carrying housing 13 with a cylindrical combustion chamber 6, in which a pot-like combustion chamber 2 in the space between the end edges of the ring-cylindrical heating gas flue, which extends along the water-cooled combustion chamber wall 11 and is thermally conductively connected to this wall 14 in individual channels 14 'sliding longitudinal ribs 4 is arranged.
  • the wall 1 of the combustion chamber 2 is selectively connected in a heat-conducting manner to the end edges 3 of the longitudinal ribs 4, as can be seen from FIGS. 2, 3.
  • the end edges 3 of the longitudinal ribs 4 are machined, for which purpose the longitudinal ribs at their end edges 3 are overturned, for example, in order to ensure that all opposing ones Rib end edges 3 have the same distance D from one another, which ensures that the combustion chamber wall to be used can be brought into heat-conducting contact with these at all end edges 3.
  • the combustion chamber is formed for the reasons mentioned in FIG. 6 from a plurality of rings 17 of the same width B, which correspond to the length L of the combustion chamber when strung together.
  • the rings 17 are provided on one side with a circumferential bend 18 pointing into the interior of the combustion chamber, which overlaps the crank-free edge 19 of the respective connecting ring.
  • the burner-side ring can, as shown, be combined in one part in a boiler construction according to FIG. 6 (vertical boiler with lintel burner chamber) with the wall 21 surrounding the burner area.
  • the strong division of the combustion chamber wall into, as shown, four rings 17 is not absolutely necessary, but in the exemplary embodiment is based on the fact that the inner shell 16 is also divided into four rings 15.
  • This division of the combustion chamber into several rings is particularly advantageous in view of the avoidability of high manufacturing accuracy of the rib support edges for the combustion chamber wall, because the combustion chamber sections can be introduced better and are also better brought to the ribs for heat-conducting contact.
  • the entire combustion chamber does not have to be formed from high-quality steel sheet if necessary, but can be limited to producing only the most condensate-prone ring 17 'from expensive stainless steel.
  • FIGS. 3-5 relate to a particular embodiment of such heating boilers, in which the longitudinal ribs 4 are obtained by unfolding a corresponding sheet metal blank, which corresponds overall and chend cylindrically rounded and made endless as an inner shell in the combustion chamber 6 is used to conduct heat to the combustion chamber wall 11.
  • 3-5 approximately correspond to the normal size of such rib designs, it is clear from this that not inconsiderable folding gussets arise between this inner shell 7 and the combustion chamber wall 11, which gussets 8 represent corresponding heat transfer barriers.
  • each rib fold 5 in the combustion chamber wall-side fold gusset 5 is one of them Gusset cross section arranged in cross section corresponding filling profile 9.
  • Relatively soft metallic material can expediently and advantageously be used in order to achieve the best possible filling of the gusset volume when the components are pressed together.
