Definitions

  • the invention relates to a sectional boiler with a combustion chamber which can be heated by a burner and a jacket which surrounds this combustion chamber and consists of a water-carrying wall, water cavities of this jacket lying opposite one another being connected to one another on the top and / or bottom of the combustion chamber.
  • a water heater of this type is known in principle from FR-OS 22 76 541.
  • the object of the invention is to make the structural design of such a water heater designed as a sectional boiler as simple as possible, in order to keep the manufacturing costs low and to obtain a robust and compact device as the end product.
  • the jacket and the connection arranged on the top and / or bottom of the combustion chamber are formed by plate-shaped, uniformly profiled boiler sections, the cross sections of which have two edge regions with contact surfaces on both sides and one connecting these edge regions, has narrower web penetrated by the water-carrying cavity, two adjacent boiler sections forming the exhaust gas ducts with their inner regions of the webs that are offset from the contact surfaces of the edge regions.
  • the sectional boiler has a combustion chamber 1 heated by a burner 11a or 11b and essentially consists of the jacket 2, wholly or partially surrounding this combustion chamber 1, formed by a double wall, which here essentially consists of similar boiler members (20) and which carry water connecting nippein 25 is composed.
  • the cross section of the boiler sections 20 has two edge regions 28 with contact surfaces on both sides and a narrower web 21 connecting these edge regions 28 and penetrated by water-carrying cavities 5.
  • FIG. 1 shows a sectional boiler composed, for example, of three boiler sections, namely one internal and two external boiler sections 20.
  • the essentially plate-shaped boiler members 20 can be produced inexpensively from aluminum or another light metal alloy in the extrusion process and are braced together at the edge regions with their mutually parallel flanks by means of connecting elements (not shown) to form a block and connected in a water-conducting manner via nipples 25.
  • At least one of the internal boiler sections 20 is dimensioned shorter than the external boiler sections 20, which laterally delimit this combustion chamber 1 and form the jacket 2, and thus does not extend to - like the external boiler sections to the floor, but forms with its lower end the ceiling of the combustion chamber 1.
  • the cavities 5 of the boiler sections 20 can be closed on their faces by end plates 26, for example by welding or screwing, the contour of the end plates 26 corresponding to the uniform profile of the boiler sections 20.
  • the inner regions 27 of the flanks of the boiler members 20, which are offset from the contact surfaces of the edge regions 28, are provided with projections 23, for example fins, which promote the heat exchange between the exhaust gases flowing upward from the combustion chamber 1 and the water contained in the cavities 5 of the boiler members 20
  • a sectional boiler according to the invention can thus be assembled within the scope of the invention in any size from any number of any number of identical boiler sections 20 of any variable length, the size of the combustion chamber 1 also being able to be varied as desired.
  • To manufacture the sectional boiler the required number of boiler sections 20 in the lengths required in each case is first produced cut to length. The cavities 5 of these sections are closed by welding or screwing on the end plates 26 at both ends and the boiler members 20 thus produced are then connected to one another by means of the nipples 25 and braced to form a heating block.
  • boiler sections 20 are not only completely identical to one another but are also of the same size.
  • These boiler sections 20 each consist of a web 21 which delimits the exhaust gas ducts 19 with its outer sides within the sectional boiler, and of two thickened edge regions 28 which form contact surfaces and which the web 21 connects to one another.
  • the web 21 of the boiler member 20 encloses a cavity 5 which is parallel to the outer sides of the web 21 and open to one of the two end faces of the boiler member 20.
  • the outer sides of the web 21 which serve to guide the exhaust gas are again provided in the inner regions 27 with projections 23 which favor the heat exchange, for example ribs.
  • Link boiler shown in Figure 2 are two boiler sections 20 with the open end faces of their cavities 5 facing upwards and bridging the combustion chamber 1 next to each other between two outside boiler members 20, the cavities 5 with their open end faces downwards and through the aligned cavities 5 to form the combustion chamber 1 below, laid, the water jacket 2 forming boiler members 20 are added, the cavities 5 are open upwards.
  • the remaining boiler members 20 can be clamped together to form a block by means of connecting elements (not shown).
  • the cavities 5 of all boiler members 20 are to be connected to one another by nipples 25 which can be inserted into transverse bores and in this way form a water-carrying system within the boiler block, which system can be incorporated into a circulation heating system via a flow 16 and a return 17.
  • the upwardly open cavities 5 of the boiler members 20 bridging the combustion chamber 1 can be closed by end plates 26, the contour of which corresponds to the uniform profile of the boiler members 20.
  • the links 20 of a sectional boiler according to FIGS. 1 and 2 are very simple and correspondingly cut to length by extruded profiles Can be produced inexpensively, but their use as end members is comparatively not economical because the share of these end members in the energy yield is relatively low.
  • boiler elements 20 manufactured in the extrusion process need to be used for the middle links, but boiler sections with a smaller volume and lower efficiency for the outer links, according to FIGS. 3 and 4 one or more uniformly profiled, that is to say producible in the extrusion process, on opposite sides Kesselglieder 20 block consisting of steel end members 29 connected.
  • a sectional kettle consists of the two steel end links 29 and a single central link 20, which has a uniform profile and can therefore be produced in an extrusion process, preferably from aluminum.
  • This middle member 20 consists of a rib-shaped extensions 23 and thereby exhaust gas guides 19th delimiting plate. Accordingly, the two steel end members 29 connect to the inner regions 27 of the flanks of the uniformly profiled boiler member 20, which they are spaced apart by the extensions 23 and, together with the apexes of these extensions 23, limit the exhaust gas ducts 19.
  • the middle member 20 forming the exhaust gas guides 19 extends only over approximately half of the total height, namely only over the upper height range, and delimits the combustion chamber 1 with its underside an atmospheric burner 11 b can be accommodated with an axial direction which runs in a plane parallel to the vertical planes of the boiler members 20 and 29.
  • the two end members 29 advantageously also take on the functions of a pressure plate. By tapering the end member 29 in the combustion chamber area, no additional central member is required to create a combustion chamber 1 of sufficient width.
  • steel end links 29 are connected to those sides of a link block consisting of a plurality of uniformly profiled boiler links 20, on which these boiler links 20 lie flush against one another with their edge regions 28.
  • these uniformly profiled boiler elements 20, which can be produced by extrusion only extend over the upper height range of the Boiler and limit the combustion chamber 1 with their lower ends.
  • a fan burner 11a with an axis perpendicular to the plane of the uniformly profiled boiler elements 20 can be arranged, or it can enter this combustion chamber 1 through a recess 30, indicated by dash-dotted lines, of one of the end elements 29, a group of atmospheric Extend burner 11b.
  • the outer boiler sections 20 of the section block for cooling the combustion chamber 1 can extend to the combustion chamber floor 7 and laterally limit the combustion chamber 1.
  • the two steel end members 29 can be formed by the legs of a U-shaped member which, with its web, embodies the combustion chamber floor 7 and thus forms the water-carrying jacket 2 of the combustion chamber 1.
