Definitions

  • the invention relates to a tube heat exchanger in which the tubes are traversed by combustion gases.
  • the invention is based on the knowledge that a condensate can be made usable if the heat exchanger is given a specific design. Accordingly, the invention is based on the object of designing the exchangers mentioned at the outset in such a way that through a conscious accumulation improved cleaning of the combustion gases and / or heat storage are possible from condensate.
  • At least one tube for forming a condensate accumulation has one or more projections similar to a dam, reducing its clear cross-sectional area, and / or an inclined rise. Accordingly, the condensate is deliberately not discharged, but at least collected or dammed at one point, these collections preferably extending essentially over the entire length of the horizontal or inclined pipe sections.
  • the condensate that accumulates can then be used as a heat accumulator and heat the air touching the pipes. At the same time, the contact area between the combustion gases and the condensate increases within the pipes, which results in better cleaning of the combustion gases.
  • the protrusions or the increased location due to the inclined slope do not prevent the condensate from draining off. If a certain amount of condensate has accumulated, the protrusions or the highest points are overcome, but a reservoir-like accumulation remains.
  • the heat exchanger has a large number of approximately horizontal, one above the other straight pipes 1 made of plastic; adjacent, stacked pipes 1 go about 18o o - manifold 2 into each other in a manner that will be of fed upward in the direction of the arrow 3 combustion gases having a temperature of about 6o o C back and forth through the heat exchanger, the bottom of the Leave the direction of arrow 4 at a temperature of about 4o O C.
  • the air used to cool the combustion gases is fed in countercurrent from below in the direction of arrow 5; it leaves the exchanger in the upper region in the direction of arrow 6. While, according to the embodiment according to the drawing, the cooling air is guided in counterflow to the combustion gases, it can also be guided and directed transversely to the tubes 1 in other embodiments.
  • the tubes 1, seen in the flow direction of the combustion gases, are provided in the end region with a projection in the manner of a small dam in the lower floor region;
  • small plastic molded bodies 7 are glued into the tubes according to FIGS. 2 and 3 or fastened in some other way. They have a T-shaped cross section in such a way that the vertical cross bar 8 is the actual one. Dam or projection forms.
  • the greatest height h should be 1o - 5o% of the inside diameter of the pipe.
  • the condensate from the combustion gases collects on the bottom of the tubes 1, a corresponding, flat liquid accumulation being formed.
  • the free condensate surface thus created serves to better influence the combustion gases;
  • thermal energy is stored, which can be passed on to the outside air, which e.g. is of great importance when the air is fed to the boiler or furnace from which the combustion gases to be cooled come.
  • the attachment of the plastic molded body 7 at the ends of the tubes 1 is simple because the elbow 2 and tubes 1 are plugged together. There is a socket connection as a plug connection with an O-ring seal.
  • the condensate Due to the tempered flue gases, the condensate is at a correspondingly high temperature. Therefore, it is also possible to use the heat exchanger according to the invention as a radiator, primarily by using the heat stored in the condensate.
  • the radiator designed in this way is preferably used for space heating.
  • the heat exchanger can also be used to preheat the combustion air for a boiler system, which also has the effect of lowering the temperature of the combustion gases.
  • the tubes 2 lie one above the other; they are inclined so that condensate can also accumulate.
  • the inclination of adjacent tubes 2 is in opposite directions, in such a way that their mutual distance - when viewed in the direction of tubes 1 - is greater in the area of the elbows 2 than at the opposite end (B greater than A) (in tubes 1 and elbows 2 with practically the same diameter dimensions).
  • the condensate is indicated at K.
  • 5 and 6 provides pipes 10, which are laid to and fro, but are practically in a horizontal plane. Its inlet section 11 is downward towards the pipes 1o and the outlet region 12 of the pipes 1o, on the other hand, is inclined upward from the pipes 1o in order to enable the condensate to accumulate over the entire length of the pipes 1o.
  • the inclination of the pipe sections 12 is advantageously chosen to be so small that the condensate can flow through them before the pipe sections 10o completely fill with the condensate and thereby even close the heat exchanger.
