Definitions

  • the present invention relates to a heating system one serving as a heat store, with water as a heat storage medium filled container and one present in the container Combustion chamber for heating the storage water Burning a fuel.
  • Such heating systems are known in many ways.
  • the use of 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 it gives off heat.
  • Another one, especially for heating fresh water Possibility used is in the container with to arrange a heat exchanger for the storage water which the drinking water to be heated is led to. Also Combinations of both variants are known.
  • the heat loss is caused by heating the Combustion chamber balanced by a fuel in the combustion chamber, for example oil or gas is burned.
  • the one there generated heat 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 water vapor present in the resulting flue gas condensed on the inner walls of the combustion chamber. This Condensation leads together with that in the fuel gases or Flue gases contain sulfur for acid formation and thus corrosion of the combustion chamber walls.
  • the invention has for its object a heating system of the type mentioned above to indicate these disadvantages does not have.
  • a heating system of the type mentioned above to indicate these disadvantages does not have.
  • the occurrence of Condensation on the inner walls of the combustion chamber as far as can be prevented.
  • combustion chamber at least partially surrounded by a wall at a short distance is, the one formed between the combustion chamber and the wall Space to the container is open.
  • the combustion chamber is opposite the wall in this area Temperature of the storage water surrounding the combustion chamber isolated. That in the space between the combustion chamber and the wall existing water is namely due to the small volume warms up relatively quickly and forms a thermal cushion between the combustion chamber and the cooler storage water. Since the space is open to the container, an exchange can be made of the water in the room with the outside in the tank existing water take place, so that overheating of the Water is prevented. Nevertheless, the container wall remains open a higher temperature than without such a wall, in particular at a temperature at which no condensation forms takes place. It has been found that with a Heating system according to the invention temperatures of the combustion chamber wall reached in the order of approx. 70 ° to 80 ° C can be, i.e. significantly above the temperature of approx. 40 ° C, below which condensation forms.
  • the wall is in particular at least on the underside of the Combustion chamber available and on one side of the combustion chamber pulled up than on the opposite one Page.
  • 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. Likewise, it has turned out to be advantageously exposed the combustion chamber with a circular Form cross-section and the wall accordingly to be designed in the form of a circular section.
  • 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 via supply and return lines in the circuit with 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 lower 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 are 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 highlighted.
  • 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 arranged, through which the combustion evolving flue gas to the chimney.
  • the boiler 1 can in addition to the oil burner 2 and heat exchanger 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 but 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, the corresponding 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 corresponding 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 in particular favorable way to prevent the formation of condensation and thereby corrosion of the combustion chamber 3 largely be prevented.
