Definitions

  • the present invention relates to a wood-burning stove, having a combustion chamber, which has an air supply and a heating gas line, wherein a filter material is provided in an area through which combustion air can be absorbed by the particulate matter in a burning phase and desorbable in a later fire phase.
  • the EP 1 750 071 discloses a stove, which causes a reduction in particular of the carcinogenic fine dusts in the Anbrandphase. This type of fine dust filtration has proven to be very efficient, but over time the filter material becomes contaminated and loses its effectiveness. In addition, there is the problem that existing stoves have no particulate matter and therefore contribute significantly to the particulate matter.
  • the stove according to the invention comprises a combustion chamber, from the combustion air is passed through a filter material, are absorbable by the particulate matter in a burning phase and desorbable in a later fire phase.
  • the filter material is arranged in a removable filter cartridge having an air-permeable support layer on which the filter material on or rests. This allows the filtering of the combustion air with high quality, since the filter material can be cleaned at regular intervals and keeps its effect.
  • emissions of carcinogenic organic particulate matter such as pro-cyclic aromatic hydrocarbons (BACs)
  • BACs pro-cyclic aromatic hydrocarbons
  • the filter cartridge forms a combustion chamber limiting wall portion.
  • the filter cassette can partially or completely form a ceiling section of the combustion chamber, so that the combustion air flows through the filter cassette and can be cleaned there.
  • the flow-through cross-sectional area of the filter cassette can be selected to be particularly large, so that slow flow velocities ensure good cleaning.
  • existing stoves can be equipped with a filter cartridge according to the invention, since in the region of the combustion chamber above usually a Schugasum Arthur is provided which is removable and can be replaced by a filter cartridge according to the invention.
  • the filter cartridge preferably has a lower air-permeable carrier layer and an upper air-permeable carrier layer, between which filter material is arranged.
  • the carrier layers may be formed, for example, as metallic networks.
  • an edge portion of the lower and upper carrier layer can be enclosed in a U-shaped frame in cross-section, so that the filter material is enclosed and will not fall out even when cleaning can.
  • the filter material can also be subjected to a pressure jet cleaning.
  • the frame of the filter cartridge may comprise downwardly projecting support webs which are arranged on an inner side of a side wall of the combustion chamber. This ensures an exact positioning of the filter cartridge and closes possible bypass openings, which could reduce the efficiency of cleaning the combustion air.
  • the filter cartridge is on opposite sides in the edge region in each case on the side walls of the combustion chamber, so that no additional holding means must be mounted.
  • the filter cassette can also be positioned via other fastening means in the combustion air flow.
  • the filter material is preferably a packed bed of volcanic ash, lapilli, pumice, rock foam and / or expanded clay.
  • the bulk layer consists of individual grains, for example, have a diameter between 2 mm and 70 mm, in particular 5 mm and 20 mm, so that the flow resistance is not too high, but also the flow rate within the filter cartridge is so far reduced that a cleaning the combustion air can take place.
  • the filter material also contains several different Filtennaterialien.
  • the filter material may comprise a metal oxide as catalyst, in particular iron oxide.
  • metal chips can be used as a catalyst.
  • the catalytically active iron oxide can be applied in the form of nanoparticles as a coating on at least part of the packed bed.
  • the carrier layers or other components of the filter cassette may also be coated with nanoparticles of iron oxide.
  • a filter cassette which has a lower air-permeable carrier layer and an upper air-permeable carrier layer made of a heat-resistant material, between which an enclosed bed is arranged as a filter material, by means of which particulate matter in a Anbrandphase absorbable and are desorbable in a later fire phase.
  • This filter cassette can be retrofitted especially in existing stoves are when a wall portion of the combustion chamber, in particular in the upper region, is removed and the filter cartridge is installed. As a result, a large number of existing stoves can be provided with an effective filter to reduce particulate pollution during the combustion process.
  • a stove 1 comprises a combustion chamber 2, in particular for wood, but also for other fuels, which is surrounded by side walls 3.
  • a bottom 4 In the lower part of a bottom 4 is provided for storing the fuel and an air supply.
  • the combustion air generated in the combustion chamber 2 flows through a filter cartridge 5, which limits the combustion chamber 2 upwards.
  • the purified combustion air is then introduced through an exhaust duct 20 into a chimney.
  • the filter cartridge 5 rests on opposite sides with an edge portion on the side walls 3 of the combustion chamber 2.
  • 5 downwardly projecting webs 8 are provided on the filter cartridge, which rest against the inside of the side walls 3 or are arranged adjacent to these.
  • a web 13 of the filter cartridge 5 In the rear region, a web 13 of the filter cartridge 5 is also provided, which is arranged adjacent to a rear wall of the combustion chamber 2.
  • the filter cassette 5 is arranged on the upper side of the combustion chamber 2, on which a plate-shaped Edelgasumtechnisch is provided in older stoves. For retrofitting older stoves with such Edelgasum admir this can be dismantled are then to mount the filter cartridge 5 according to the invention at the top of the combustion chamber 2.
  • the filter cartridge 5 is in the FIGS. 2 and 3 shown in detail.
  • the filter cartridge 5 comprises a lower support layer 12 and an upper support layer 7, each formed of an air-permeable metal mesh.
  • the carrier layers 7 and 12 are bordered at the edge by a frame 6 which is U-shaped in cross-section and rests with an upper leg 9 on the carrier layer 7 and engages under a lower leg 11, the support layer 12.
  • the webs 8 and 13 are fixed.
  • a bottom portion 10 of the frame 6 is arranged circumferentially on the end face of the filter cartridge 5. As a result, a filter material 15 is enclosed on all sides in the filter cartridge 5.
  • the filter material 15 is formed as a bed, wherein the grain size of the filter material is greater than the mesh size of the carrier layers 7 and 12. This prevents falling out of filter material 15 from the filter cartridge 5, even if, for example, a cleaning takes place in the pressure jet process.
  • a filter material in particular a bed of volcanic ash, slag, lapilli, pumice, rock foam and / or expanded clay is used, which are each introduced into the filter cartridge 5 in a suitable grain size.
  • a metal oxide in particular iron oxide, may be contained as a catalyst in the filter material 15.
  • the metal oxide can be introduced in the form of metal shavings or as a coating, wherein catalytically active nanoparticles are preferably applied to at least part of the filter material.
  • the carrier layers 7 and 12 may also be provided with a coating.
  • the thickness of the filter cartridge 5 is chosen so that with respect to the filter material 15, the flow resistance is not too high, for example, the filter cartridge may have a thickness between 1 to 5 cm, in particular 2 to 4 cm. If a larger grain size is used, the filter cartridge can be made slightly thicker, while a smaller grain size makes a thinner design required. With the filter cartridge 5 according to the invention, the particulate matter pollution, especially in the Anbrandphase, can be significantly reduced. For this purpose, tests were carried out according to DIN / EN 13 240, wherein in the following Table 1 the test results are shown in a stove with a standard deflection for the combustion air, while Table 2 shows the test results in a stove with a filter cartridge according to the invention.
  • the particulate matter was measured in two tests with a stove without filter cassette with 24 or 26 mg / Nm 3 .
  • the particulate matter pollution could be reduced to 9 mg / Nm 3 . This corresponds to a reduction of the particulate matter load by more than 75%.
  • Lapilli with a nano-coating of iron oxide was used as filter material.
  • the filter cartridge 5 may also contain multiple layers of one or more different filter materials. The layers may be separated from each other by one or more air-permeable middle layers. In addition, several filter cassettes 5 can be provided in the combustion air flow in a stove 1.
