Definitions

  • the invention relates to a three-pass boiler, consisting of a water-carrying housing with a combustion chamber, deflection chamber, starting from this second train, overflow chamber and starting from this, with a third train leading to the exhaust gas connection in the form of a plurality of small-diameter individual pipes.
  • Such three-pass boilers are known, for example, according to DE-U-93 04 468.
  • the three trains and also the deflection and overflow chambers can be implemented in different ways, which ultimately depends on it whether it is a reversing combustion chamber or a combustion chamber open at the rear, from the rear open end of which the heating gases flow forward to the deflection chamber, from which, in such cases, the heating gases flow in such boilers into the third train, either over the combustion chamber or can also be arranged below this.
  • Special measures additional double-skin heating surface make it possible to operate such boilers and the associated heating system with a relatively high degree of annual utilization.
  • the invention is based on three-pass boilers of the type mentioned, the task of improving such a three-pass boiler in such a way that the design saves weight and weld seams in particular and integration of the deflection chamber requires less effort and the overflow chamber has a comparatively larger water-cooled area from the second to the third train with comparatively equally good accessibility.
  • the second train in the form of a single tube with a smaller in relation to the diameter of the combustion chamber and in relation to the diameter of the individual tubes of the third train is substantially larger diameter, which with a manifold piece forming the deflection chamber is connected at the end region of the combustion chamber to its peripheral wall provided with a corresponding opening and with its other end opens into the overflow chamber, which is covered with an insulated closure cover at the front of the boiler, the other boundary walls of which are arranged in the water-carrying interior of the housing.
  • the otherwise complex deflection chamber is replaced by a simple elbow piece, which is only possible in that the second train no longer consists of a large number of individual tubes, but only of a single tube with a correspondingly large diameter, which in particular involves the amount of welding work significantly reduced and ultimately the space required for this in the water-carrying housing.
  • the overflow chamber from the second to the third train is no longer attached to the outside of the boiler housing, but protrudes into the water-bearing interior, attached to the water on the front wall of the housing, i.e. the remaining boundary walls of this overflow chamber are cooled down to the sealing cover and require what the side walls of these Chamber concerns, no external isolation.
  • combustion chamber is arranged in one half with respect to the vertical longitudinal center plane of the housing and the third train extending over the second train in the other half, and on the other hand the elbow section of the second train under 40 - 50 °, preferably 45 °, is connected to the peripheral wall of the combustion chamber.
  • the three-pass boiler consists in a conventional manner of a water-carrying housing 1 with combustion chamber 2, deflection chamber 3, from this starting second train 4, overflow chamber 5 and starting from this, with a third train 7 leading to the exhaust gas connection 6 in the form of a plurality of smaller-diameter individual pipes 7 '.
  • the present differs, and as can be seen in particular from Fig. 1, that the second train 4 in the form of a single tube 4 'with smaller in relation to the diameter D of the combustion chamber 2 and in relation to the diameter D1 the individual tubes 7 'of the third train 7 is of substantially larger diameter D2.
  • This single pipe is connected to a manifold piece 8 forming the deflection chamber 3 at the end region 2 'of the combustion chamber 2 to its peripheral wall 2' 'provided with a corresponding opening 8'.
  • the pipe 4 ′ opens into the overflow chamber 5, which is covered with an insulated closure cover 9 at the front of the boiler and whose other boundary walls 10 are arranged in the water-carrying interior 11 of the housing.
  • the diameter D2 of the second train forming single pipe 4 ' is, for example. 30 cm and the diameter D of the combustion chamber, for example, 70 cm, while the third train forming individual pipes 7' have a diameter D1 of, for example, only 6 cm.
  • the entire package of individual tubes 7 'for the third train is arranged such that, in addition to the upper boundary wall 10, the other boundary walls of the overflow chamber 5, as can be seen in FIG. 2, can be dimensioned as long as possible by means of an arcuate design.
  • the combustion chamber 2 and the trains 4 and 7 are assigned, as can also be seen from FIG. 2, in such a way that the combustion chamber 2 with respect to the vertical longitudinal center plane 12 of the housing 1 in one half and that which extends over the second train 4 third train 7 is arranged in the other half.
  • This assignment and arrangement is essentially and how shown below the upper third in the water-carrying housing 1 in order to create a sufficiently large vapor space there.
  • the manifold piece 8 of the second train 4 which simplifies the whole construction, is connected in the exemplary embodiment at 45 ° to the peripheral wall 2 ′′ of the combustion chamber 2, which, in contrast to conventional three-pass boilers, has a bottom 13 which, as illustrated, on the rear wall 14 of the housing , is anchored.
