Definitions

  • the invention relates to the formation of hot gas on heating boilers according to the preamble of the main claim.
  • heating boilers equipped therewith have proven themselves well and have been introduced on the market.
  • Such boilers are operated today with what is known as the sliding temperature and are therefore referred to as low-temperature boilers.
  • the invention is therefore based on the object of solving this problem, that is, a heating gas train training of the type mentioned is to be improved in such a way that taking into account the corrosion protection needs of the objective of being able to operate such heating boilers also as low-temperature boilers with a sliding temperature at higher output ranges, Can be taken into account.
  • U-shaped profiles are known according to DOS 15 Ol 676 and 20 25 472, but these profiles form the wall itself in the boilers concerned, which separates the water-carrying from the gas-carrying space.
  • the design principle according to the invention can also be used not only for trains which have only a water-cooled wall, but also for trains which have water-cooled walls on the opposite side.
  • the U-profiles are used on the one hand to form the heating gas flues, but on the other hand their base webs simultaneously form a largely condensation-preventing double wall on the water-carrying train wall, because they are arranged close to one another, and, as will be explained in more detail below, a specifically metered one Heat transfer to the wall takes place, which has the effect during start-up processes, but also during operation, particularly in the low-temperature area of the boiler, that the areas towards the fume cupboard can heat up more quickly because of the lower heat transfer there, which counteracts or largely prevents the accumulation of condensate.
  • the legs of a profile are pressed together, which is done with a suitable wedge-shaped tool that is pressed between the free legs of two adjacent profiles, where applicable. it can also be ensured that the resulting traction channels narrow towards the discharge side in adaptation to the decreasing gas volume.
  • the draft wall is rounded to form a tube or partial tube and closed with a longitudinal weld seam
  • a multitude of heating gas flues with approximately triangular cross sections are created around the pot-like combustion chamber to be used later, each alternating with their distal base points against the combustion chamber and are directed against the wall.
  • heating gas train design according to the invention and its various design options are explained in more detail below with reference to the drawing of exemplary embodiments.
  • the rear cover 25 is provided with a flue gas outlet connection 26.
  • the deflection chamber 27 is arranged in the tube formed by the wall on the burner side (burner not shown).
  • the pot-like combustion chamber 28 sits in the free space between the heating gas flues 8, and the flue gas collecting chamber 28 'is located behind it.
  • This boiler structure is not absolutely essential, just as the combustion chamber 28 must be cylindrical and the heating gas flues 8 must be arranged in a ring structure. Opposite 8 additional post-switching heating surfaces can be arranged behind the combustion chamber 28 or the heating gas flues. Furthermore, the walls of the combustion chamber can also be designed as water-carrying double walls, the interior of which is connected in a suitable manner to the other interior of the housing 22. This would be the case in which the heating gas flues 8 are delimited on both sides by water-cooled walls 3, 3 '.
  • the sheet metal blanks for the rib profiles 1 look like they can be seen in FIG. 2 before they are deformed into U-profiles.
  • the side slots are used to compensate for thermal expansion, but are not absolutely necessary.
  • the profiles thus formed are placed close to one another in the sense of FIG. 4 on the sheet metal cut of the wall 3 which later forms the pipe, is still planar or is slightly bulged, and is welded to the wall in the region of the longitudinal welding slots 16.
  • a wedge-shaped tool (shown in simplified form as a triangle) is pressed between the free legs 9 of each two adjacent profiles 1, so that the profiles then appear in cross-section, as can be seen in FIG. 5 and FIG. 1.
  • Opposite longitudinal weld seams can also be laid in the gussets 30 '(FIG. 5) which form. It is also possible to bend the legs in the sense of FIG. 6.
  • annular shell 30 can advantageously either wholly or, as shown, partly freely project in the region of the tube Flue gas collection chamber 28 'are arranged, but for which it is essential that these are welded with their inner edge to the profiles 1 in order to ensure heat flow from the profiles into the shell 30, so that this can also heat up quickly.
  • thermally conductively connected in some areas means the slot welding connection described above, but it is also possible, and this is also preferred because of the much lower cost, to base the webs 2 with, for example, a tungsten electrode (ie without the addition of additional welding material ) to be welded or melted.
  • the attachment of slots 16 of different sizes and distances can be omitted, and the attachment takes place in such a way that the stitching area or the resulting thermal bridge 5 becomes narrower or smaller from front to back.
  • the flow channels of the heating gas flue which are U-shaped in cross section are formed by rectangular profiles 10, i.e. two adjacent profiles 10 complement each other to form a U-profile.
  • U-profiles 1 can also be arranged at a distance from one another, the free surfaces of wall 3 being covered with correspondingly wide intermediate webs 12 in order to maintain the double wall principle in all surface areas.
  • the legs 9 or ribs of the profiles 1, 10, 11 can, as indicated in FIG. 7, be provided at intervals with flag-like bends 19. 7, 8, the wall of the combustion chamber 28 which is not water-cooled in this case is designated by 3 ".
  • a water-cooled additional wall 3 ′ for the heating gas flue (FIG. 9) also arises (boilers of this type are known), in which the profiles described on both walls 3, 3 now occur 'are arranged and determined according to the same principle.
  • the arrangement can be such that the longitudinal edges 17 of the opposing profiles 1, 10, 11 end approximately in the same intermediate plane or protrude somewhat into the space 18 of the other profiles .
  • an arrangement according to FIG. 9 is advantageously chosen such that the longitudinal edges 17 run closely above the welded points of the heat-conducting bridge 5.
  • legs 9 can also have a common base web, and the whole can also be designed, for example, as an extruded profile with a suitable wall thickness.
  • the train formation is shown in a straight extension, which can of course also be used in this form depending on the structural conditions on the boiler.
  • trains in this design generally have more or less curved walls 3 or 3 ', i.e. the exemplary embodiments shown also apply to such curved surfaces.
  • An essential aspect of the entire hot gas train training, as described, is as summarized send to a certain extent draining hot gas-carrying areas in such a way that condensate formation is largely prevented, but on the other hand it is ensured that any condensate deposits are evaporated as quickly as possible when the boiler is restarted.
  • train designs described is not limited to trains in heating boilers, which is for the sake of simplicity, but that they can also be used in heat exchangers (gas / liquid) in which condensate formation Must be taken into account, that is, in particular heat exchangers, which are used in the form of separate devices downstream of a boiler.
  • train training is not limited to thermal devices for burning liquid or gaseous fuels.
