- Such heating systems are in different embodiments known. In old buildings you will often find single stoves, by burning wood, coal, gas or Heating oil or generate electricity directly from electricity or in the case of night storage heaters, sometimes with a delay hand over to the room. With central heating, the one mostly in the basement of the boiler through a heat transfer medium, usually water, rarely steam or Air supplied to the rooms to be heated. It will be there over radiators, convectors, and more recently delivered to the room via underfloor heating.
- a heating system is to achieve a comfortable one Indoor climates, i.e. those that affect the users of the room so-called perceived temperature, which is an average Indoor air temperature and average temperature of the room enclosing surfaces corresponds, should depend on the physical Activity and individual needs in a range of about 16 to 24 ° C. Further requirements for a heating system are the lowest possible purchase and fuel costs and the lowest possible pollutant emissions.
- the conventional heating systems work with a burner device, which is operated with oil or gas.
- a heatable heat transfer medium such as preferably water
- the radiant heat temperature drops considerably, so that a degree of utilization of only about 25% is achieved.
- the flame mantle embraces usually a temperature range from just 400 to 500 ° C, effectively only about 350 ° C flame jacket temperature be exploited. Therefore, a sufficient water temperature To achieve in the boiler must take a long time Period of heat energy supplied via the burner device what additional energy consumption means.
- the object is achieved in that the heat-dissipating components directly the flame of the burner device are exposed.
- the heat-dissipating Components directly on the flame of the burner device arranged.
- At least those of the flame the heat-dissipating device closest to the burner device Components exposed to the flame core. As is known the temperature in the flame core is highest. Thereby there is an optimal utilization of the flame core temperature, which directly on the at least one heat-dissipating component is transmitted, which is directly in the flame core area located.
- the invention are in the interior arranged in the combustion chamber with heat-dissipating components the chamber containing the heat transfer medium fluidically connected.
- the temperature is only transferred with minor losses to that contained in the heat-dissipating components Heat transfer medium.
- the increase in the temperature of the heat transfer medium by the direct influence of the temperature of the The flame core causes the heat transfer medium to circulate inside the boiler between the heat-dissipating Components and the container containing the heat transfer medium.
- a degree of utilization of thermal energy is more reached than 70%.
- the high circulation of the heat transfer medium and its elevated temperature cause a Double walls of the boiler can be omitted. Thereby the boiler can be made smaller, using raw materials and saved materials for its manufacture can be. In addition, it is cheaper to manufacture.
- the heat-dissipating components in the interior are preferred the combustion chamber as hollow profiles of any cross-section educated.
- the heat-dissipating components for example a triangular, circular or streamlined Have cross-section.
- heat-dissipating components from hollow profiles that are different from the hollow profiles another group of heat-dissipating components are, with both groups of heat-dissipating components are interconnected.
- the heat transfer medium receiving, spaced apart Hollow profiles can be designed as water pockets, which e.g. have a triangular cross section.
- This group of heat-dissipating components can be combined with heat-dissipating components can be connected, for example a smaller one have circular cross section and with which the Containers containing heat transfer medium are connected to to achieve a sufficient circulation of the heat transfer medium.
- the largest sections are expediently in terms of area at least one of the heat-dissipating components directly exposed to the flame core in order to have the largest possible area of attack to allow for the flame core.
- the combustion chamber or the heat transfer medium containing chamber at least partially in cross section narrowed. This makes a flow effect similar to one Venturi nozzle achieved and the circulation of the heat transfer medium elevated.
- the heat-dissipating ones exist Components and the container containing the heat transfer medium preferably made of stainless steel or cast iron.
- the fuel for the Burner device preferably oil or gas and the heat transfer medium are preferably water.
- the boiler 1 has a cylindrical Container 2. On an end wall outside of the Container 2, a burner device 3 is arranged, the a burner nozzle 4 directed into the interior of the container 2 from which a flame 5 emerges. The flame will always referred to below as the flame core 5.
- the means Encloses footrests 6 on a floor 7 stored container 2 a combustion chamber 8, which is also cylindrical is and has a smaller diameter than Tank 2 of the boiler 1.
- a flue gas discharge pipe 9 which will be explained later.
- Chamber 10 formed in which there is a heatable heat transfer medium 11, for example water.
- a heat-dissipating component 13 which is circular and a circular Has cross section. Radially from the annular heat-dissipating Component 13 are at an angular distance of 90 ° to one another displaces further heat-dissipating components 14 in a star shape arranged, the heat-dissipating component 13 with the the chamber 10 containing the heat transfer medium 11 fluidically connect.
- the heat-dissipating components 14 are Tubes of circular cross section attached to their respective Ends with the annular heat-dissipating component 13 and the wall of the combustion chamber 8 are welded.
- Heat transfer medium 11 both the annular heat-dissipating Component 13 as well as the tubular heat-dissipating components 14 flow through.
- the heat transfer medium 11 circulates by the direct heat of the flame core 5 in the heat-dissipating components 13 and 14 and in the chamber 10.
- the heat transfer medium moves due to the circulation process 11 according to the arrows shown in Figs. 1 and 2.
- form the lower tubular heat-dissipating components 14 a heat carrier inlet 15 and the upper tubular heat-dissipating components 14 a heat transfer outlet 16.
- the boiler 3 is substantially cuboid educated.
- 3 to 5 correspond to the same reference numerals those in Figs. 1 and 2.
- the combustion chamber 8 and thus the adjacent heat transfer medium 11 containing chamber 10 are narrowed in its central region educated.
- the combustion chamber 8 is at least partially, namely outside of the heat-dissipating Components 13 and 14 are provided with a cover 17. This Cover covers the largest possible area for recording the radiant heat. This leaves only a small gap between the top of the combustion chamber 8 and the container 2 required in which the heat transfer medium 11 located.
- This heat-dissipating component 13 as can be seen from FIG. 4, is triangular in cross section formed, the top of the triangular shape directly is directed to the flame core 5. This will make the impact surface of the flame core 5 on the heat-dissipating component 13 enlarged.
- a similar component 13 is in the the burner device 3 opposite area of the Combustion chamber 8 arranged.
- the heat-dissipating components 13, which project essentially vertically into the combustion chamber 8, are each with tubular heat-dissipating components 14 with the chamber containing the heat transfer medium 11 10 connected so that a flow passage between the heat-dissipating components 13 and 14 and the chamber 10 for the heat transfer medium 11 is created.
- the flame core 5 has a direct effect on the heat-dissipating material arranged therein Component 13 a.
- the heat transfer medium 11 circulates in the heat-dissipating components 13 and 14 and in the chamber 10.
- the boiler 1 according to FIG. 3 has one Boiler feed connector 18 and, according to FIG. 4, a boiler return connector 19 on.
- the boiler flow connector 18 and the heat transfer medium 11 containing chamber 10 are with a heat recovery device 20 connected.
- a shut-off valve 21 having line 22 leads from the boiler flow connector 18 to a circulation pump 23, which in turn preferably with a stainless steel pipe spiral 24 connected is arranged inside the flue gas discharge pipe 9 is.
- the shut-off valves 21 and 25 are intended for repair and maintenance purposes to the To interrupt the flow path of the heat transfer medium 11.
- For additional heat recovery will be a certain amount the heat transfer medium 11, e.g. 20% of the volume flow used and is by means of the circulation pump 23 via the pipe spiral 24 circulated in the flue gas discharge pipe 9.
- the removed heat transfer medium 11 with from the preliminary flow increased temperature directly mixed with the return. This is compared to the flow temperature lower return temperature raised and thus additional Heat energy recovered.
