Definitions

  • the invention relates to a boiler for burning liquid or gaseous fuels according to the preamble of the main claim.
  • Boilers of the type mentioned are known from EP-A-0 414 926 and are used in different, but in principle identical construction forms.
  • this well-known boiler design applies both to sheet steel and cast iron boilers, the cast iron boilers being made from relatively narrow, one-piece and core-cast individual members (see DE-A-20 17 992 and also FR-A-22 37 141) exist, which, nippled in the area of relatively small overflow openings on the water side, are joined to form a block consisting of a large number of individual members.
  • a boiler design according to FR-A-1 084 896 also has a similar link construction, according to which the links are sealed to one another with O-ring seals.
  • the abutting surfaces of one or the other link are equipped with ring grooves for receiving the O-rings. It may be left open whether this sealing arrangement and design actually meets the sealing requirements, but in any case it can be the different thermal expansions in the walls, namely in the wall, which on the one hand the combustion chamber to the water-bearing interior and the wall that the water-bearing Interior space limited on the other hand, not enough, and the invention has for its object to provide such a boiler, a sealing system that better suits the different expansion conditions at the different temperatures exposed walls.
  • the boiler consists of a water-carrying housing 3, provided with supply and return connections 1, 2, which is penetrated by a combustion chamber 4, the two openings 5 of which are provided with closures 6, 7, one of which 6 is the insert opening 8 for the burner and the other 7 contains the exhaust system.
  • the water-carrying housing 3 is formed from two middle members 10 and two end members 11, 12, the corelessly shaped members 10 to 12 being directed towards one another and sealed together with their opening edges 13.
  • the firing chamber 4 is the limit in each case
  • Wall 14 is formed as a web 15 encircling the links, which ends as an integrally molded part in the connecting plane E of the link in question, the transverse wall 16 of the boiler members 10 supporting the web 15 being provided with a plurality of openings 18 connecting all the interior 17 of the members.
  • these openings 17 are very large in relation to the total cross section of a link, ie the sum of all cross sections 17 corresponds practically to the total cross section of a link in the water-carrying area.
  • 1 is a horizontal boiler with a pot-shaped combustion chamber 20 inserted in the combustion chamber 4.
  • the two central links 10 are H-shaped in cross section, while the two end links 11, 12 Are U-shaped, the end member 11 has an annular collar 11 'for the connection of the burner 9 carrying the combustion chamber closure and the end member 12 has a flue-side rear wall with a cast-on flue gas outlet connection 21. All the members are designed in the region of their opening edges 13 such that all the connecting edges 13 'have interlocking steps 30, in which areas seals are arranged, which is explained in more detail in relation to FIG. 3.
  • the tension connection of the links to one another is achieved by the fact that all the links 10, 11, 12 are tensioned with tension rods 28 which are evenly distributed over the circumference of the housing and which span the links in their openings 18 Cross walls 16 pass through much smaller openings 29 sealed.
  • tension rods 28 Such an end of the tension rods, which are shown in their distribution over the entire circumference in FIG. 2, is illustrated in FIG. 4.
  • This arrangement of the tension rods 28 in the passage of the water-carrying interior advantageously ensures that both the outwardly sealing ring seals 31 and the ring seals 31 'lying on the combustion chamber side can be clamped together at the same time.
  • the coreless formability of the links 10 to 12 also makes it possible for the water-side to be distributed evenly over the circumference in the links the respective link outer wall 33 and the wall 14 delimiting the firebox 4, stiffening ribs 34 can be arranged, which end in front of the opening edges 13.
  • the shape of the ribs 34 is illustrated in FIG. 1 and their arrangement with respect to the boiler cross section in FIG. 2.
  • a sealing ring 31 ' is clamped between the two surfaces 32, 32' of the webs 15, which extend perpendicular to the longitudinal axis of the combustion chamber, in the joint regions between the opening edges 13 of two members 10 to 12, and a further sealing ring 31 is arranged in one end or the other 35, secured against axial displacement, between the ends 35 of the outer link walls 33 which overlap in the axial direction.
  • a flat ring seal is particularly suitable, as shown, and an O-ring seal for the sealing ring 31.
  • the surface 32 extends at one end of the web 15 in one plane, and the surface 32 'at the other end of the web 15 is delimited towards the water side by an annular collar 36 which overlaps the other end of the adjacent link.
  • a collar 36 can also be provided on the combustion chamber side, as indicated by dashed lines, in order to shield the sealing ring 31 'against the direct exposure to heating gases.
  • a sealing ring receiving groove 37 is provided in one or the other of the overlapping ends 35 of the link outer walls 33.
  • at least one of the overlapping ends 35 is advantageously provided with a slip-on chamfer 38 in order to facilitate the joining of the links without risk of damage to the sealing rings 31.
