Definitions

  • the invention relates to an incinerator made of sheet metal for household waste or the like.
  • the known incinerators are equipped with fireboxes, the walls of which are lined with chamotte panels, the thermal conductivity of which is low.
  • Simple sheet metal furnaces are also known, the walls of which are directly exposed to the fire and therefore burn out after a relatively short use.
  • the incinerators equipped with bricked-up, relatively small fireboxes are usually made of cast iron, are only optimal for certain fuels and are also very expensive to buy
  • the main disadvantage of simple sheet-metal stoves is that the side walls, which are directly connected to the flames Come into contact, are easily made to glow during the firing process, which increases the risk of injury and increases the heat radiation significantly.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims and in particular in the main claim, solves the problem of creating a sheet metal incinerator in which soot and ash particles are filtered out from the flue gas or from the flue gases, so that only dry and relatively clean flue gas in reaches the chimney.
  • the invention can be applied to an incinerator in which the outer side walls and the rear wall of the combustion chamber are shielded from the direct action of the burning material using interchangeable sheet metal parts.
  • a combustion furnace 1 for household waste or the like shown in FIG. 1 consists of a rectangular box 2 made of sheet metal, which is covered by a protruding plate 3 and is equipped with a firing door 4 on the front. At the corners of the bottom plate 5 (Fig. 2) of the box 2, brackets 6 to 9 made from profiled plate or the like can be attached.
  • the base plate 5 is provided within the furnace 10 (FIG. 3) with a rectangular opening 11, over which a grate 12 is inserted.
  • An ash pan 14, which is also made of sheet metal, is located below the opening 11 1 at attached angles 13.
  • the two side walls 15, 16 of the combustion chamber 10 and the rear wall 17 (FIG. 4) consist of inserted sheets, which can optionally be made from waste sheet.
  • the side walls 15, 16 and the rear wall 17 of the combustion chamber 10 can, as shown in FIG. 3, be fastened to the relevant outer walls of the box 2 (FIG. 1) by means of bolts 18 to 21 and associated spacer bushings 22 to 25 or as from Fig. 4 can be seen to be held in the inserted position by inserted angles 26, 27.
  • sheets 31 to 33 are advantageously curved in a wave or zigzag shape inserted, which are used for heat transfer, wherein they transfer the heat from the side walls 15, 16 and the rear wall 17 to the box 2, from which the heat is released into the room air.
  • sheets 31 to 33 gratings or the like can also be used for direct heat transfer.
  • the plate 3 already mentioned (FIGS. 2, 3) has an opening 34 which is covered by a removable cover 35.
  • a bushing 36 (FIG. 1) is inserted, into which an exhaust pipe 37 is inserted.
  • a shut-off valve 38 (FIG. 2) which is used to adjust the smoke exhaust.
  • the exhaust pipe 37 (FIG. 2) is seated in a sleeve 39 of a preferably rectangular heat exchanger 40, which may have an inlet 41 which widens inwardly and is covered by a grid 42.
  • the guide ribs or guide plates 43 (FIG.
  • the central region (FIG. 2) of the grille 42 can expediently be equipped without baffles 43 and be provided with a downward-pointing cone or a pyramid 46 which directs the incoming smoke gases to the grille 42.
  • a continuous pipe sleeve 48 is inserted on the upper wall 47 of the heat exchanger 40, which protrudes a little into the interior 49.
  • an exhaust pipe 50 is inserted, which leads to a chimney of the house, not shown.
  • the grille 42 In addition to deflecting the inflowing flue gases, the grille 42 also causes a coarse filtering process in which the larger pieces of paper entrained by the flue gases are retained by the grille 42 and only fall back into the combustion chamber 10 as ash parts or are entrained by the flue gas flowing through them will.
  • a cylindrical shape can also take place, in which the combustion chamber 10 is also cylindrical.
  • the associated inner walls and the corrugated heat conducting plates are also cylindrical.
  • the heat exchanger 40 can be designed as an integrated component of the incinerator 1.
  • the exhaust pipe 37 according to FIG. 2 ceases to exist.
  • a continuous outer jacket can be provided, which has a favorable manufacturing effect. With this construction, the lower area of the outer jacket is intended for the combustion chamber and the upper area for the additional heat exchanger.
  • Can-shaped shaped bodies 51 made of sheet metal are arranged in the heat exchanger 40 above the grid 42.
  • these can-shaped shaped bodies 51 can consist of empty cans.
  • These can-shaped shaped bodies 51 are then arranged with the opening facing downward and with the bottom facing upward in the heat exchanger 40.
  • the bottoms of the can-shaped shaped bodies 51 are provided with one or more holes 52.
  • the flue gases flowing through the can-shaped shaped bodies 51 reduce their flow speed so much that even light soot and ash particles are no longer entrained and can settle. This means that the flue gas entering the chimney is also removed from most of the light ones. Soot and ash particles freed.
  • the shaped bodies 51 store some of this heat. The remaining heat is made usable for space heating via the outer wall of the heat exchanger 40.
  • the chimney draft regulating effect of the shaped bodies 51 is of essential importance for the combustion and for the heating efficiency.
