Definitions

  • the present invention relates to a heating system with a Heat storage serving, filled with water as a heat storage medium Container and a combustion chamber present in the container circular cross-section for heating the storage water Combustion of a fuel, the combustion chamber at least on their underside at a short distance from a partially circular in cross section Wall is surrounded and between the combustion chamber and wall-formed space is open to the container.
  • Such heating systems are known in many ways.
  • the use The heat stored in the water can take place in that the water via supply and return lines in the circuit to heating surfaces, such as radiators and underfloor heating, where there is heat emits.
  • Another one, especially for heating fresh water is in the tank with the storage water to arrange a heat exchanger through which to be heated Drinking water is led. Combinations of both variants are known.
  • heat loss is caused by heating the combustion chamber balanced by a fuel in the combustion chamber, for example Oil or gas being burned.
  • the heat generated is transferred from the combustion chamber to the storage water surrounding the combustion chamber.
  • a problem here is that in the fuel gas and / or the The resulting flue gas water vapor on the inner walls the combustion chamber condenses. This condensation water brings together with the sulfur contained in the fuel or flue gases Acid formation and thus corrosion of the combustion chamber walls.
  • This problem can be reduced by having the combustion chamber at least partially surrounded by a wall at a short distance is, the space formed between the combustion chamber and the wall the container is open.
  • Such a heating system is known from FR 2 629 907. at this heating system is a wall surrounding the combustion chamber available on both sides of the combustion chamber only to below half the height of the combustion chamber is sufficient. The is accordingly low water circulation caused by this wall. It is therefore done only a little exchange of water in the space between the walls and combustion chamber with the water outside in the container.
  • DE 34 12 331 C 1 shows a heating system, but not the Combustion chamber surrounding wall of the type mentioned.
  • the invention has for its object a heating system of the beginning to improve the type mentioned.
  • the effectiveness of the wall surrounding the combustion chamber can be improved.
  • the height of the combustion chamber wall is the water circulation in the space between the wall and the combustion chamber improved. This means that there is a more intensive exchange of water the water in the container. Among other things, this can cause overheating of the water in the space between the wall and the combustion chamber be prevented.
  • the combustion chamber Due to the wall arranged at a short distance around the combustion chamber the combustion chamber is in this area versus temperature of the storage water surrounding the combustion chamber. That in that Space between the combustion chamber and the wall of the existing water namely warmed up relatively quickly due to the small volume and forms a heat cushion between the combustion chamber and the cooler storage water. Since the space is open to the container, can an exchange of water in the room with the outside in the tank existing water take place, causing water overheating is prevented. Nevertheless, the container wall remains on a higher one Temperature than without such a wall, especially at a temperature where there is no condensation. It turned out that with a heating system according to the invention temperatures the combustion chamber wall in the range of approx. 70 ° to 80 ° C can be achieved, i.e. significantly above the temperature of approx. 40 ° C, below which condensation forms.
  • the wall is on the underside of the combustion chamber and on one side of the combustion chamber is pulled further up than on this opposite side.
  • This partial shell-like encirclement of the combustion chamber is achieved that a small amount of water between Combustion chamber and wall flows through the combustion chamber is quickly heated, so that the combustion chamber wall is kept at a higher temperature than without a wall, even if the storage water due to a large heat withdrawal is strongly cooled.
  • the distance between the wall and the combustion chamber is preferably between about 2 mm and 5 mm. This has been achieved a sufficiently high temperature of the combustion chamber wall turned out to be advantageous.
  • the heating system according to the invention is particularly advantageous in connection with combustion chambers which are designed as so-called low-NO x combustion chambers, and in particular with so-called three-pass boilers in which the flue gases in the combustion chamber are deflected back towards the inlet opening before they reach the fume cupboard.
  • the use of the invention is also particularly advantageous in connection with a heating system, in which the Containers in the circuit via supply and return lines Heating surfaces, in particular radiators and underfloor heating, is connectable and an upper one in the upper area Flow heat exchanger for heating fresh water has in line with one in the lower region of the container provided for preheating the fresh water Flow heat exchanger is arranged, the combustion chamber between the upper flow heat exchanger and the lower one Flow heat exchanger is arranged.
  • Such heating systems have a pronounced temperature stratification in vertical direction and are therefore particularly multivalent Heating systems can be used in which heat from different Heat sources is used. With one Plant is the occurrence of the invention Condensation is prevented particularly effectively.
  • the invention is in the area of the upper flow heat exchanger and / or in the area of the lower flow heat exchanger at least one vertical shaft available, the lower opening of the Upper shaft preferably arranged above the combustion chamber is.
  • the shafts lead to an advantageous revolution of the storage water in the tank, as in the shafts the temperature is higher than outside.
  • the said The arrangement of the shafts has turned out to be special appropriately exposed.
  • a boiler 1 filled with water for the preparation of Hot water for heating systems and the sanitary area has a central oil burner 2 with a combustion chamber 3 and a cover arranged at the front of the boiler 1 4 on.
  • a Flue gas extractor 6 is arranged, through which the combustion evolving flue gas to the chimney.
  • heat exchangers or boiler may be provided, especially above and below the combustion chamber 3, as shown in Figure 2.
  • the combustion chamber 3 has a circular cross section and is essentially cylindrical. At hers The top of the combustion chamber has 3 exhaust openings 7, through which the flue gas can reach the flue gas outlet 6.
  • the Combustion chamber 3 is on the front side of the boiler 1 attached to the boiler 1 via holding devices 8, 9. Between the combustion devices 3 have the holding devices 8, 9 an opening 11 through which the tip of the oil burner 2 can be inserted into the combustion chamber 3.
  • the combustion chamber 3 can also on a heat storage of the heating system or be welded to the boiler 1.
  • the combustion chamber 3 is at a short distance from its outer wall 12 in the area of the bottom 13 and a side wall 14 of the Combustion chamber surrounded by a wall 16, which accordingly the circular cylindrical shape of the combustion chamber 3 as a shell Half cylinder 17 is formed.
  • the half cylinder 17 has a cross section that corresponds to a segment of a circle. The circle segment can also in other embodiments be smaller or larger than a semicircle.
  • the half cylinder 17 is via holding devices 18 at the front of the Boiler 1 attached independently of the combustion chamber 3.
  • the half cylinder 17 can also on the front of the Boiler 1 or on a heat storage of the heating system be welded on.
  • the half cylinder 17 is axial Direction so long that the wall 16 to about protrudes rear end 21 of the combustion chamber 3.
  • the storage water flowing through the space 22 becomes heated by the combustion chamber 3 and forms a thermal cushion compared to the rest of the storage water in container 1.
  • the temperature of the wall 12 of the combustion chamber 3 is thereby in the area of the wall 16 relatively high and is particularly at a temperature that is practical no condensation forms.
  • a simple metal sheet can in particular be used as the half cylinder 17 serve which can be produced inexpensively and easily is to be assembled.
  • the invention can thus be particularly favorable way to prevent the formation of condensation and thereby corrosion of the combustion chamber 3 largely be prevented.
