Definitions

  • the invention relates to a device for burning fuel in pourable form according to the preamble of claim 1.
  • Such devices are useful to z. B. burn pellets, grains or other fuels in pourable form.
  • a device which has a hollow body within a perforated boundary wall. This makes it possible to direct oxygen into the center of the piled fuel.
  • the boundary wall forms the outer edge of the device, so that air is exchanged in the radial direction during the combustion process.
  • the hollow body is provided at the upper end with an air-impermeable cover.
  • the structure of the device has the disadvantage that the combustion is not optimally introduced and can lead to excessive smoke, so that the fuel is not burned clean.
  • the air exchange is reduced transversely to the extension direction of the boundary wall, thus ensuring a clean combustion up to the edge of the accumulated fuel.
  • Fig. 1 shows a device for burning fuel with a hollow body 1, which is surrounded by serving as a boundary wall inner wall 10 and serving as a shield wall outer wall 20.
  • a boundary wall inner wall 10 serving as a shield wall outer wall 20.
  • the hollow body 1 is hollow inside and provided with through openings 2, which are distributed over the entire circumference and over the entire height of the hollow body 1. For a better overview, only a part of the openings 2 is shown in the figures.
  • the upper end 1a and the bottom 1b of the hollow body 1 are open and thus permeable to air.
  • the hollow body 1 is formed substantially conical.
  • the upper part 1 c of the hollow body 1 is movable relative to the rest of the hollow body 1, so that an inner bottom 3 with openings 2 'can be made accessible, which is arranged in the interior of the hollow body 1.
  • the inner bottom 3 is also in Fig. 2 shown.
  • a hinge 4 is indicated, which allows the upper part 1c of the hollow body 1 to tilt to the side. It is conceivable to omit the hinge 4, so that the upper part 1c is completely removable from the rest of the hollow body 1.
  • the height of the upper part 1c is less than half the total height of the hollow body 1.
  • a tube 5 leads from the outer surface of the outer wall 20 through the inner wall 10 to the inner bottom third
  • the inner wall 10 is provided over the entire surface with through holes 12, only a part of which is shown in the figures.
  • the outer wall 20, which surrounds the inner wall 10 is free or substantially free of openings and thus substantially transversely to the direction of extension of the inner wall 10 is substantially impermeable to air.
  • the walls 10 and 20 are substantially circular cylindrical and coaxial with each other (see. Fig. 3 ).
  • the device further comprises a bottom 30, which is provided over the entire circumference with through openings 32, of which only a part in Fig. 1 is drawn.
  • the bottom 30 is connected to the hollow body 1 and the walls 10, 20. To increase the stability between the two walls 10 and 20 further connecting elements may be provided.
  • the bottom 30 is annular. It is conceivable to provide a disk as the bottom 30, whereby also the area within the lower end 1b of the hollow body 1 is provided with openings 32.
  • the shape of the openings 2, 12, 32 can be arbitrary. Their size is chosen so that it is smaller than the size of the bulk material to be burned. The size of the openings 2 'in the inner bottom 3 is smaller than the size of the ignition cube used or any other suitable igniter in solid form.
  • the device is made of heat-resistant materials, for. B. made of metal.
  • the hollow body 1 with the inner bottom 2, the inner wall 10 and the bottom 30 can be manufactured, for example, from a perforated plate or grid by cutting out, bending and connecting parts in the desired shape.
  • the outer wall 20 is z. B. made of a metal sheet.
  • the device shown in the figures is suitable as an insert in a fireplace or for an existing oven, for. B. Swedish stove by being placed on the grate.
  • By means of air regulation of the furnace can the air supply are regulated. It is also conceivable to design a furnace so that the device is an integral part.
  • flammable materials are suitable in pourable form, for example, pellets of wood or other combustible biomass, grains, etc.
  • the area between the hollow body 1 and the inner wall 10 forms the combustion chamber, where the fuel is taken up and burned. For this purpose, it is poured into it, the upper part 1c of the hollow body 1 is tilted, the igniter is placed on the inner bottom 3 and the part 1c is tilted back. The igniter is finally ignited by a flame of a lighter, z. B. a burning match or drgl. Is passed through the tube 5.
  • the hollow body 1 ensures that the interior of the heap of fuel supplied with sufficient oxygen and there a uniform combustion is initiated.
  • the air permeability of the upper end 1a of the hollow body 1 supports the formation of a clean combustion flame.
  • the air can be conducted essentially in the direction of extent of the hollow body 1 or the outer wall 20 by the accumulated fuel.
  • the outer wall 20 prevents air exchange in the radial direction and thus a cooling at the edge of the heap of fuel. This ensures that the combustion zone propagates from the inside to the outside. Overall, the device allows as complete as possible combustion of the fuel from the inside to the outside, without causing excessive smoke. After completion of the combustion process, only the ash remains on the floor 30 back.
  • the hollow body may also have a different shape than shown in the figures, for. B. pyramidal or another tapered shape, cylindrical, etc. It is also conceivable to arrange a plurality of hollow body within an air-permeable inner wall.
  • the walls 10, 20 may have a different shape than shown in the figures, for. B. angular.
