Definitions

  • the invention relates to a cast iron sectional boiler according to the preamble of claim 1.
  • a sectional boiler of this type is shown and described in DE 42 20 987 C2.
  • the boiler described in more detail there is a boiler with an atmospheric gas burner.
  • the heating gases rise vertically.
  • the water hub itself is located in an upper corner area. From here, the cool return water flows downwards outside and inside as heated water upwards. The desired guidance of the water flows is achieved by means of separating and guiding ribs within the water space.
  • the invention has for its object to provide a sectional boiler of this type in which no cool return water reaches the combustion chamber and heating gas draft walls in the not yet sufficiently preheated state.
  • sectional boiler according to the invention has the features mentioned in the characterizing part of patent claim 1.
  • the boiler is designed so that mixing zones are deliberately formed to the side of the water hub arranged centrally above the combustion chamber within the water chamber. These are designed so that the cool return water penetrates and mixes with the rising hot boiler water before it then sinks into the lower boiler area. The sinking will also take place laterally from the side mixing zones, so that cooler water is not initially applied directly to the combustion chamber walls. It is important that the return water also enters these mixing zones. This is served by a shielding element in or below the water hub, which prevents a direct waste heat flow from the cool return water and directs it into the mixing zones located to the side of the water hub.
  • the shielding element can be cast on as a shell-shaped separating rib or as an overall loose part below the water hub in the water space. It is possible to form the separating rib from cast-on rib sections and to insert loose insert parts between them. The cool return water must flow over the bowl-shaped separating rib and in this way is forced into the side mixing zones.
  • Inserted pipes with lateral flow openings allow the cool return water to enter the mixing zones in an even more targeted manner.
  • the return is connected at the end to an end link.
  • the flow can branch off from the upper area of the water space.
  • An end branch of the flow parallel to the return connection is also possible.
  • a special connector enables this type of connection.
  • the boiler element has water channels 1 to form a combustion chamber 2 and a heating gas train 3.
  • the water channels 1 open into an upper water hub 4.
  • Both the boiler return 5 and the boiler flow 6 are connected to this.
  • the boiler flow 6 either branches off from one of the boiler sections upwards (FIG. 3) or at the end next to the boiler return 5 (FIG. 4). The latter is done via a connector 7 to which the safety forward and return 8, 9 is connected.
  • Mixing zones 10 are formed on both sides of the upper water hub 4, in which the inflowing hot boiler water and the cooler return water intersect.
  • the return water is raised in temperature before it reaches the lower areas of the boiler.
  • a shielding element ensures that the return water actually gets into the mixing zones 10 and does not immediately sink to the wall of the combustion chamber 2.
  • This can consist of molded separating ribs 11 in the water space (Fig. 2). It is also possible to insert a half-shell into the water hub 4 (not shown).
  • a tube 12 in the water hub 4 also fulfills this purpose, with lateral flow openings 13 allowing the cool return water to exit only into the mixing zones 10 (FIGS. 3 + 4).
  • a lower water hub 14 only serves to connect the boiler sections to one another and to equalize water between the sections, but not to connect the heating network.
