  • the lower part of the combustion chamber comprises a floor of the combustion chamber.
  • the upper combustion chamber part comprises a front wall and at least one side wall of the combustion chamber.
  • the furnace is set up in such a way that the upper combustion chamber part can be moved in the vertical direction relative to the lower combustion chamber part.
  • the furnace has a horizontal sealing plane with a (first) combustion chamber door seal in order to mutually seal the lower combustion chamber part and the upper combustion chamber part.
  • the furnace is set up for the combustion of solid biomass, for example logs and / or pellets.
  • the lower part of the combustion chamber is equipped with a pellet burner.
  • the upper part of the combustion chamber comprises two side walls of the combustion chamber. In some configurations, the upper part of the combustion chamber comprises a rear wall of the combustion chamber. In some configurations, the upper part of the combustion chamber comprises a ceiling of the combustion chamber; in other configurations, the lower part of the combustion chamber comprises the ceiling.
  • a front wall, a side wall or also a rear wall is to be understood as a wall of the combustion chamber, for example.
  • wall is to be understood here as an outer wall of the combustion chamber which (in the closed state of the furnace) provides an outer surface, that is to say an outer surface, of the furnace.
  • the furnace is thus enclosed in the horizontal direction to the front, to the side and to the rear by the front wall, two side walls and a rear wall up through the ceiling and down through the floor.
  • An inner wall is to be understood as a wall which (in the closed state of the furnace) does not provide an outer surface of the furnace.
  • the combustion chamber By moving the upper part of the combustion chamber vertically upwards, the combustion chamber can be opened, for example to clean the combustion chamber and / or to supply fuel to the combustion chamber ("refilling"). By vertically moving the upper part of the combustion chamber downwards, the combustion chamber can be closed, e.g. for a combustion operation of the furnace.
  • the lower part of the combustion chamber is rigidly arranged, that is to say cannot (easily) be moved by a user.
  • the combustion chamber By moving the upper part of the combustion chamber in the vertical direction (upwards), that is to say away from the lower part of the combustion chamber, a free space is created between the lower part of the combustion chamber and the upper part of the combustion chamber.
  • the free space provides access to the interior of the combustion chamber. This is referred to below as the open position.
  • the combustion chamber By moving the upper part of the combustion chamber in a vertical direction (downwards), that is to say towards the lower part of the combustion chamber, the combustion chamber can be closed, for example for the operation of the furnace in which combustion of fuel takes place in the combustion chamber. This is referred to below as the closed position.
  • the movable upper combustion chamber part replaces a plurality of conventional combustion chamber doors in order to enable access from several sides into the combustion chamber.
  • the upper combustion chamber part and the lower combustion chamber part are preferably designed in such a way that in the closed position, i. H. when the upper part of the combustion chamber is lowered onto the lower part of the combustion chamber, a (essentially completely) circumferential contact line is formed between the two combustion chamber parts in order to close the combustion chamber.
  • this line of contact runs in one plane, in particular in a horizontal plane, as a result of which, for example, friction between the upper and lower combustion chamber parts can be reduced when opening and closing.
  • the upper part of the combustion chamber comprises a ceiling of the combustion chamber
  • the upper part of the combustion chamber has, for example, the shape of a cover or a hood in order to release or enclose the combustion chamber volume by raising or lowering the upper part of the combustion chamber in cooperation with the lower part of the combustion chamber, that is to say to open or close the combustion chamber.
  • the upper part of the combustion chamber has, for example, the shape of a partially or completely encircling jacket in order to release or enclose the volume of the combustion chamber by raising or lowering the upper part of the combustion chamber in cooperation with the lower part of the combustion chamber, thus to open or close the combustion chamber.
  • the combustion chamber is divided into two parts, i. H. the lower combustion chamber part and the upper combustion chamber part together, in particular (essentially) completely, enclose the volume of the combustion chamber.
  • the combustion chamber is limited to the outside in all directions by the lower combustion chamber part and the upper combustion chamber part, for example.
  • the fact that the combustion chamber is composed of two halves, namely the lower and upper combustion chamber part, prevents possible operating errors, since the user can close the furnace with a single operation, namely by lowering the upper combustion chamber part. Compared to ovens with multiple doors for access from multiple sides, this reduces the risk of inadvertently leaving a door open during the firing process.
  • the upper part of the combustion chamber has a viewing area that enables a view into the combustion chamber from the outside even when the combustion chamber is closed.
  • a viewing area is equipped, for example, with one or more viewing panes or each consists of a viewing pane.
  • one side wall, two side walls and / or the front wall of the combustion chamber are (essentially) designed as a viewing window.
  • the oven has one or more viewing areas on three adjoining sides, for example on the front wall and the side walls adjoining on both sides, or on four adjoining sides, in particular also on the rear wall.
  • the furnace allows a lateral view into the combustion chamber from angles over an (essentially contiguous, in particular seamless) area of at least 180 °.
  • the upper part of the combustion chamber has no, one or more non-visible areas.
  • Non-visible areas are equipped, for example, with metal or firebrick panels or each consist of one or more metal plates or firebrick panels or a combination thereof.
  • the front wall and one or two side walls are designed in one piece, for example in the form of a one-piece viewing pane delimiting the combustion chamber on two or three sides.
  • the rear wall of the combustion chamber is part of the lower combustion chamber part, while the remaining side walls of the combustion chamber are part of the upper combustion chamber part.
  • Furnaces of these designs offer access to the combustion chamber from three sides in the open position and, as the rear side wall is part of the lower combustion chamber part, prevent fuel or combustion residues from falling backwards out of the combustion chamber. This increases the operational reliability of the furnace, for example.
  • the lower part of the combustion chamber is free from the outside wall, i. H. the upper part of the combustion chamber includes all (lateral) outer walls of the combustion chamber.
  • the lower part of the combustion chamber has one or more inner walls, that is to say walls which do not provide an outer surface of the furnace or the combustion chamber when the combustion chamber is closed.

  • Such overall heights are advantageous, for example, for an inner wall that runs along a side wall of the combustion chamber and / or for an inner wall that runs along the front wall of the combustion chamber, or also for all of the inner walls.
  • an inner wall is provided along the rear wall of the combustion chamber. This has a greater overall height than other interior walls, for example.

  • the combustion chamber has a seal between the lower combustion chamber part and the upper combustion chamber part.
  • This seal is referred to herein as the first combustion chamber door seal because, like a door seal, it reduces or prevents, for example, the escape of flue gases into the vicinity of the furnace and / or an undesired air supply into the combustion chamber between the lower combustion chamber part and the upper combustion chamber part.
