Definitions

  • the invention relates to an atmospheric gas boiler according to the preamble of claim 1.
  • a gas boiler of this type is known, for example, from DE-A-37 05 230.
  • This gas boiler consists of two end members and a middle member, which is nippled in a conventional manner with the end members.
  • This central link has a special design in that it is very long vertically and thus divides the combustion chamber located below the upshift heating surfaces into a two-part chamber, a burner tube being arranged below each chamber in the region of the likewise water-carrying floor.
  • the rear wall of the combustion chamber and the heating gas shafts is not designed to carry water.
  • the links are precisely adapted to the accommodability of the burner tubes, i.e.
  • gas surface burners for example in the shape of a hemisphere, which take up more space and require a correspondingly large insertion opening, cannot be accommodated in such a gas boiler.
  • the object of the invention is to make the links forming the water-carrying housing nipple-free so that a combustion chamber which is sufficiently large for each type of burner and has a sufficiently large insertion opening results and the combustion chamber rear wall facing the insertion opening is water-cooled, and this is associated with the requirement that each link be provided with its own flow and return area in order to ensure a consistent, vertically oriented diagonal flow for each link from the lower return to the upper flow area, the or the intermediate link (s) should correspond to such a diagonal flow in terms of the shape of their water-carrying interior.
  • the intermediate elements therefore do not have a water-bearing base part, i.e. the combustion chamber is limited at the bottom by a simple sheet metal cut, and the lower front edge of the shaft part forms the upper edge of the burner insertion opening, in which only a detachable, heat-insulated combustion chamber closure plate is arranged.
  • the gas boiler according to the invention is, as will be seen even better from the special drawing description, to a certain extent, as I said, to the most necessary "emaciated" compact boiler, which nevertheless has a relatively large transmission area, is known to vary in width within limits, and in the Different types of burners can be easily installed.
  • a gas burner with a hemispherical burner surface is preferably used in this gas heating boiler, since this best meets the essentially cubic combustion chamber.
  • An embodiment is preferably provided for the gas boiler in such a way that the side wall members and also the at least one intermediate member are provided with mutually gas-tightly connectable webs both in the area of the combustion chamber rear wall and the discharge shaft and on the front of the boiler in the area of the discharge shaft and on the front of the boiler in the area of the discharge shaft.
  • This enables the links to be connected to one another without any complications and easily sealed, which in this respect do not require any previously usual nippling. Since these non-water-bearing webs go directly from the water-carrying cavities of the limbs, the heat absorbed by the webs is also dissipated directly to the heat transfer medium.
  • the gas boiler shown in a highly schematic form in FIG. 1, consists of a water-carrying housing 1 with a multi-part exhaust duct 2 and combustion chamber 3, in which an atmospheric gas burner is to be arranged.
  • the bottom 11 of the combustion chamber 3, which is not water-cooled, is only indicated by dashed lines, and the outer casing and the extractor hood with extractor connection are not shown.
  • This schematic representation shows the exposed arrangement and design of the forward and return flows V and R particularly clearly.
  • the housing 1 is formed from two hollow side wall cast members 5, which extend over the total height H of the combustion chamber 3 and the exhaust duct 2 located above it and leading to the exhaust, wherein, as shown, between the two side wall cast members 5 two also hollow cast intermediate members 6 are arranged and these are hydraulically indirectly connected to the side wall members 5 by a common forward and return connection V, R. 4, each intermediate member 6 is formed from a shaft part 7 and from a hollow extension 8 'forming the water-cooled rear wall 8 of the combustion chamber 3. This water-bearing shaft part 7 of the intermediate element 6 delimits individual discharge shafts 2 'with its outer walls 9 and the adjacent walls 10 of the side wall elements 5 (see FIG. 3).
  • the combustion chamber 3 which is bounded at the bottom by its non-water-bearing bottom 11, is provided in the upper region on the burner insert side with a detachable, heat-insulated combustion chamber closure plate 12 (FIGS. 2, 6), and below this the gas burner 4 with its end plate 4 'is arranged.
  • the water-carrying extensions 8 'of the intermediate members 6 are at the lower end and the side wall members 5 are aligned with return line pieces 14 and the water-carrying shaft parts 7 are at the upper end diagonally to the lower return line piece 14 and the side wall members 5 are also included provided in alignment with flow line pieces 15, which line pieces 14, 15 are liquid-tight against one another clamped each form the flow connection V and the return connection R of the boiler.
  • the side wall members 5 and also the intermediate members 6 are provided with mutually gas-tight webs 16 both in the area of the combustion chamber rear wall 8 and the exhaust duct 2 and in the front of the boiler in the region of the exhaust duct 2. Liquid seals are therefore only to be provided between the line pieces 14, 15, while the seals 13 only have to seal gas-carrying spaces.
  • the webs 16 extend on all links essentially only vertically, since the individual exhaust ducts 2 'must of course remain open upwards and downwards.
  • the entire link assembly forming the housing 1 is held together in a known manner by external tensioning elements 17, since only one is shown in FIGS. 2, 3, since it is not nippled.
  • the gas-side walls 10 of the side wall members 5 and the walls 9 of the intermediate members 6 are provided with enlarged transmission areas, such as knobs or ribs, which is indicated in FIG. 4.
  • a gas burner 4 in the form of a hemispherical gas surface burner 4 ' is used in the practically ideal cubic combustion chamber 3, which does not require any further description, since it is known per se.
  • the housing 1 from the side wall members 5 and only one intermediate member 6, or even from three intermediate members 6, if another type of burner (ear torch with only two tubes) was used without having to change anything the width of the pipe burner (e.g. with three or four pipes) should be required.
  • another type of burner ear torch with only two tubes
  • the flow and return line pieces 14, 15 are advantageous and thus arranged in the sense of a compact design with the greater part of their length L on the side of the walls 10 of the side wall members 5.
