Definitions

  • the invention relates to a device for improving the use of heat in individual fireplaces, such as chimneys, tiled stoves or the like, which are fired in batches with fuels such as wood (in particulate form or as pellets), straw or other renewable fuels or coal fuels.
  • fuels such as wood (in particulate form or as pellets), straw or other renewable fuels or coal fuels.
  • biomass i. wood-fired firing systems make the biggest contribution to the use of regenerative energies. For this reason and also because of the achievable improvement of the heat supply security in private households, these furnaces enjoy increasing popularity.
  • Batch-fired furnaces usually do not dissipate the heat evenly over a long period of time, but produce a high amount of heat after a firing phase with rather weak heat release for a limited period of time. This phase is then followed by a burnout phase, during which the heat dissipation gradually fades away.
  • a burnout phase during which the heat dissipation gradually fades away.
  • measures are desirable that the maximum of heat dissipation during the Lower the main phase of the combustion a little and provide for increased heat dissipation during the burnout phase.
  • the fireplaces are often followed by devices in which the hot exhaust gases are passed through channels, through the walls of the exhaust gases give off heat, which thus does not escape through the chimney into the open, but is still harnessed for space heating. Furthermore, these channels can be surrounded by mineral substances in which heat is stored, in particular during the hot main phase of the combustion. In masonry tiled stove systems with manually set combustion chambers, these channels are usually realized individually in the form of masonry gas flues in compliance with the technical rules of the stove and air heater industry.
  • a heating top for hearth or the like is known, which is designed as a heat storage attachment and inside a helical coil of predetermined length, which can be traversed by exhaust gases.
  • this heating element is not flexible to adapt to different ovens.
  • the object of the invention is to provide a heat storage device with which the heat output of a fireplace to be heated living space is to be uniform while increasing the firing efficiency, which can be mounted in a space-saving and easy way to the fireplace and flexible to the chimney conditions and the characteristics of the fireplace can be adapted and, moreover, facilitates the firing of the fireplace.
  • the heat storage device may have storage elements 5, 6a, 6b, 9 whose cross-section may be round, but also other shapes, such as a square or square rectangular base can have.
  • the storage elements 5, 6a, 6b, 9 can form rings in that they enclose an internal cavity, through which the exhaust gases are led to the connecting piece 8.
  • This heat storage device can be placed on the exhaust port 3 of the fireplace 1, wherein the connection via an adapter 4, which can be adapted on the one hand to the design of the exhaust nozzle 4 of the fireplace 1 and on the other hand, a device for adjusting the function of the channel for the Wearing fire-fighting help.
  • This An85 kau is preferably realized in the form of a bypass channel, which can be opened during the Anfeuerphase the fireplace 1, to minimize the flow resistance for the exhaust gas between hearth and chimney and a rapid heating of the chimney and thus a rapid construction of the To ensure chimney draft.
  • the function of the Anfeuer Anlagen can be controlled via a flap in the adapter 4, which can open or close the bypass channel.
  • the storage rings 5 are placed as a stack.
  • the number of rings can be adapted to the respective requirements, resulting for example from the construction of the chimney plant or the type of fireplace.
  • the respective upper two storage rings 6a, 6b have cutouts which permit the use of a connecting piece 7 for the connection of a connecting piece 8, through which the furnace is connected to the chimney.
  • a cover 9 is arranged, which closes the storage system, so that no exhaust gas can escape into the installation room.
  • exhaust gas guide elements are used. These exhaust elements can have the same height as the storage rings and can be used during the placement of the storage rings in this.
  • the exhaust gas guide elements have a central inner channel, for example in the form of a tube, which forms the bypass channel of the cheek aid after the exhaust gas guide elements have been joined one over the other. When the bypass channel is open, the exhaust gases can be discharged directly, i. With minimal flow resistance and largely without heat losses, flow into the connector 8 and facilitate in this way the start-up process by quickly heating the chimney.
  • the exhaust gas guide elements may be formed around the inner tube as helical or helical segments, so that the exhaust gases are guided approximately in the form of a helical line around the inner channel upwards and there finally open into the connecting piece 8.
  • One function of the exhaust gas guide elements is the generation of turbulences, which allow better heat transfer from the exhaust gas to the storage rings. In addition, they cause by a longer residence time of the discharge within the storage elements an increased heat emission of the exhaust gases and thus an improved utilization of the fuel energy.
  • the exhaust gas guide elements can be designed differently in order to cause different strong exhaust gas deflections. About this different strong exhaust deflections, the length of the exhaust path can be influenced until reaching the connector, so that even with a given construction height of the storage rings different lengths of flue gas can be realized.
  • the exhaust gas guide elements can be designed so that different types of elements can be combined, whereby the flexibility in adapting to the local conditions is again significantly increased.
  • the combinability of various exhaust gas guide elements within a storage ring system offers the possibility of taking into account the volume change of the exhaust gas as a result of the cooling during the passage through the storage rings, in that the cross section of the exhaust gas path tapers towards the top.
  • the exhaust elements need not necessarily be Wendelsegemente, but may also have approximately square base, or be formed by means of baffles.
  • the exhaust elements are preferably made of metallic material because of the simple design options, but can also be made of mineral materials, concrete or the like.
  • the storage stones 5,6a, 6b, 9 are made of a substance that is to have a good heat storage capacity and is heat resistant and fireproof. That can by fireclay, concrete, ceramics, magnesite, magnetite or similar substances.
