Definitions

  • the invention relates to a stove for heating rooms by means of air heating or convection with at least one furnace and the use of such a stove.
  • the wood-burning stoves with their high heat output are a full-fledged heating source with which individual rooms or floors can be easily heated ,
  • the heat generated is generally emitted to the environment as radiant heat via a viewing window and secondly as convection heat via ventilation slots.
  • Wood pellets are small, cylindrical pellets made from wood chips or sawdust, for example, as waste in sawmills. Pellets are easy to transport and store and have a high energy density compared to wood. In addition, their ash emissions are less than 1 percent.
  • the wood pellets which can be bought in sacks, for example, are burned in special pellet stoves, usually equipped with a pellet storage container.
  • pellet stove due to its size and type of burner, it is only suitable for burning pellets. If the supply of wood pellets is exhausted, the user must first buy them from specialist retailers.
  • electrical power is required to operate a pellet stove. The electricity is needed, for example, to convey the wood pellets from the storage container into the combustion chamber.
  • the invention has for its object to provide a stove of the type mentioned, which is optimized in terms of its handling and the choice of its location.
  • the invention is characterized in that the operation of a stove, which can be used, for example, as full heating for entire buildings, in particular for houses, is not only limited to the use of wood pellets, but also lump wood can be used. If the supply of wood pellets is exhausted, you can simply switch the stove to operation with lumpy wood.
  • the burner, but also the combustion chamber, fuel supply, fresh air inlet and flue gas outlet must be designed or designed in such a way that both wood pellets and lump wood can be used as fuel.
  • a power connection is required to operate the furnace, especially for the burning phase. As soon as the device has reached a certain operating temperature, a power supply is no longer necessary.
  • the switchable stove also works, namely with chunky wood when there is no electricity available.
  • the stove can therefore also work in the event of a power failure after it has been switched to operation with lumpy wood.
  • you can also use the stove in rooms where there is no power connection. From a safety point of view, the operation of the pellet wood stove is guaranteed even without power supply, but with the restriction that the combustion is not optimal.
  • the stove especially the combustion chamber, is specially designed.
  • the dimensions are chosen so that even logs that are much larger than pellets can be easily placed in the oven.
  • a commercially available, pure pellet stove would not be suitable for firing with lumpy wood due to its dimensions alone.
  • a storage container for wood pellets is provided. This storage container holds in particular a volume of about 63 liters, which - depending on the performance requirement - is sufficient for an operation of up to 70 hours. From this storage container, the wood pellets can be fed to the combustion chamber via a conveyor, in particular via a screw conveyor.
  • a storage container for lumpy wood can also be provided; The combustion chamber is then assembled by hand.
  • electronic monitoring is provided.
  • the combustion, the power output and / or the supply of wood pellets can thus be monitored. The user no longer has to supervise the fire himself.
  • an automatic control of the combustion, the power output and / or the pellet supply is also ideally provided.
  • the user can set the desired temperature, as he knows it from an ordinary heating system, and then leave the stove to itself. If wood pellets are used, he does not have to worry about the further supply of the fuel, since this is done automatically by the integrated monitoring and control.
  • the stove designed in this way can be operated in a temperature-dependent and / or time-dependent manner.
  • a viewing window can be provided, on the one hand emits the generated heat as radiant heat into the installation room, which on the other hand also allows the user to look at the flames - similar to an open fireplace.
  • a viewing window can be provided, on the one hand emits the generated heat as radiant heat into the installation room, which on the other hand also allows the user to look at the flames - similar to an open fireplace.
  • lumpy wood as fuel which is known to be heavily sooty, soiling or sooting of the inside of the lens can occur relatively quickly! So that you do not have to clean the window at regular intervals to maintain a clear view of the fire, it can be advantageous if the window is flushed with air from the inside.
  • combustion air is supplied, an air flow flowing along the inside of the pane is always generated, which ensures that the combustion gases are largely kept away from the viewing pane.
  • an external combustion unit can also be provided on the stove, which is particularly advantageous for use in low-energy houses.
  • Fig. 2 shows a variant of a stove according to the invention in a perspective rear view
  • Fig. 3 shows the variant of Fig. 2 in cross section.
  • a stove 1 which can be operated both with wood pellets and with lumpy wood, is shown obliquely from above in a perspective view.
  • the stove 1 consists of a housing 2, which is formed from a base part 3, a cover part 4 and side walls 5.
  • a flue gas outlet 6 is provided in the cover part, which is connected to a smoke exhaust pipe in the operating state.
  • a combustion chamber 7 is provided in the front part of the stove, which is separated from the surroundings by a viewing window 8. The heat generated in the combustion chamber 7 is emitted to the environment as radiant heat via this viewing window 8.
  • the viewing window 8 Above the viewing window 8 are ventilation slots 9 through which part of the heat, namely in the form of poor convection, is also released to the environment.
  • the viewing window 8 can be swiveled sideways to the front.
  • FIG. 2 Another variant of a stove 1, which can be operated both with wood pellets and with lumpy wood, is shown in FIG. 2.
  • the stove 1 shown here also has a housing 2 with a base part 3, cover part 4 and walls 5 Ventilation slots 9 can be seen in the upper part of the stove 1.
  • the flue gas outlet 6 is arranged on the rear wall of the housing 2.
  • a corresponding fresh air inlet 10 which is also arranged next to the flue gas outlet 6 on the rear wall of the housing 2
  • air for firing is regularly introduced into the combustion chamber 7 during operation of the stove 1.
  • the direction of flow of the fresh air or the flue gases in the Area of entry 10 and exit 6 shown.
  • the flue gases are conducted to the flue gas outlet 6 via lines located in the rear part of the stove 1.
  • the wood pellets are fed from a storage container, not shown, to the combustion chamber 7 via a conveyor device 13, here designed as a screw conveyor.
  • FIG. 3 shows the embodiment previously described with reference to FIG. 2 in a schematic cross section.
  • the individual flow directions of the fresh air or the flue gases within the stove 1 are shown.
  • fresh air first enters the stove 1 below the combustion chamber 7 through the inlet 10. Part of the fresh air is then directed upwards to the combustion chamber 7, where it ensures optimal combustion of the respective fuel.
  • the other part of the fresh air supplied is branched off beforehand and fed to a line system 11.
  • the air exits at the outlet 12 above the viewing window 8.
  • the outlet 12 is designed in such a way that the air can flow evenly from top to bottom on the inside of the viewing window 8. In this way, the exhaust gas flow containing soot is prevented from soiling the pane 8.
  • the operating principle of the conveyor 13 of the stove 1 can also be seen in FIG. 3.
  • the individual pellets Via the nozzle 15, which is connected to the storage container (not shown), the individual pellets reach the screw conveyor of the conveyor device 13. This transports the pellets to a level above the combustion chamber 7 from where they follow the force of gravity reach the grating 14.
  • the screw conveyor and thus the pellet supply, the power output and the combustion can be controlled via an automatic monitoring and control device.
  • the supply of fresh air can also be regulated via this device.
