Definitions

  • the invention relates to a Klein85 Too with an outer shell, surrounded by refractory bricks firebox, a combustion air supply via inlet openings in the side walls of the firebox and a flue gas discharge, wherein the inlet openings for the combustion air formed by horizontal slots between spaced-apart projections provided blocks of the side walls of the firebox are.
  • small hearth is understood in particular tiled stoves, stoves, fireplaces and other heat-generating systems od od renewable fuel in the form of logs. Like. Burn.
  • a small hearth of this kind is known for example from CH 177 894.
  • the firebox is limited by special building blocks which, by means of suitable projections, define slots for the lateral inlet of the combustion air supplied from below.
  • wedge-shaped building blocks In the lower part of the furnace is enclosed by wedge-shaped building blocks, which are surrounded by L-shaped building blocks and ribs, resulting in approximately L-shaped air ducts.
  • Heat generation with the renewable energy source wood is in the area of tension between the demands for a sustainable and climate-friendly energy supply on the one hand and the potentially harmful particulate matter emission on the other.
  • the main problem to be solved is the previously inadequate ventilation of the combustion chamber, which is a major reason for inadequate combustion and resulting high levels of particulate matter development.
  • soot and polycyclic aromatic compounds are formed by incomplete combustion in the small hearth.
  • a well-ventilated combustion process would have the advantage that hardly any toxic carbon monoxide is produced during combustion and that hardly any soot and tar deposits form in the chimney, which can lead to a chimney fire.
  • the object of the invention is therefore to construct a small fire place that meets the upcoming requirements.
  • the above object is achieved in that the slit limiting blocks are cuboid and have four side surfaces and two end faces, and that the projections are provided on two adjacent side surfaces of each block as a slot-forming spacers to the outer shell and to an overlying or underlying block.
  • the combustion air inlet openings can not be bound to the size of holes or channels in the building block, but can be kept in the size required even for an excess combustion air supply by providing appropriate distances between the building blocks and the outer shell.
  • the outer shell can also be an already existing furnace, in the firebox of the building blocks are used. Above all, in this case, the distance to the outside securing projections are particularly advantageous.
  • the fuel can be supplied evenly from all sides with combustion air, and thus the emissions can be reduced to a minimum.
  • Cuboid blocks with protrusions are already known several times. That's how it shows DE 34 26 239 block-shaped building blocks with projections on two sides, but represent two other side surfaces. The difference is essential because the building blocks of DE 34 26 239 are provided with projections on a side surface and an end face. Since the stones are hollow and the projections represent connections in the cavity, the end projections must engage in corresponding frontal holes. It would not be possible to rotate the blocks 90 ° to use the protrusions as spacers outwards or inwards.
  • the US 4,108,733 shows a lattice brick with maximum heat exchange surface. Projections for spacing are only at the bottom. Recesses are formed on the four side surfaces, which have grooves or waves that pass through the height, so that two lattice blocks arranged next to one another form further channels which correspond to the channels in the interior. These stones can not be arranged so that slots remain outwards and up or down.
  • the DE 20 164 26 shows frame-like building blocks, which have projections and depressions on the four sides, so that they are plugged together. Blocks are provided as toy or building elements and described only in a solid connector. The openings in the flat frame side can be covered by plates on which also projections and depressions are formed in order to form corner constructions can.
  • Two different wall thicknesses of the side walls of the firebox can be achieved when building blocks according to the invention have a rectangular cross-section, wherein they can be provided in a first arrangement edgewise and lying in a second arrangement one above the other.
  • the protrusions are preferably provided on each side surface at intervals corresponding respectively to the single or double width of the side surface. This arrangement of the projections ensures that the blocks can be superimposed offset over the corner.
  • recesses are provided in the two other side surfaces, that is, in the third and fourth side surface of the module, so that the components can be overlapped one inside the other.
  • the recesses are formed at two different depths, the depth of the deeper recesses being equal to or greater than the height of the protrusions, and the depth of the shallower recesses being less than the height of the protrusions.
  • the blocks can be set by horizontal displacement either without slots or with slots on top of each other. So it is for example advantageous, the lowest two or three layers of building blocks without Laying intermediate space, so that a circumferentially closed collection space for ash is achieved.
  • the blocks are arranged so that the projections engage in the deeper recesses, so that the side surfaces of the blocks lie directly on top of each other. In the other layers, the blocks are arranged offset by half the length, whereby the projections engage only in the shallower depressions, so that the slots arise.
  • a small fire place in particular a tiled stove, stove od.
  • Has an outer shell 1 of any kind which is created for example from stove tiles to build the combustion chamber 2 or which may also be part of an existing small fire place, with a new combustion chamber is provided.
  • a base plate or a bottom element 4 limits the combustion chamber 2 downwards.
  • side walls 3 are provided at least on three sides, which are created from building blocks 5 according to the invention.
  • the blocks 5 are drawn schematically, so that their details according to Fig. 2 to 5 in Fig. 1 are not apparent.
  • the arrangement of the blocks 5 is such that lower layers, for example two or three, are airtightly arranged on the bottom element 4 and on top of each other, and enclose an ash space.
  • the blocks 5 are laid at a distance from each other, so that the bearing joints are not tight, but form slots 6, flows through the combustion air into the combustion chamber 2.
  • the combustion air supply 7 is formed on the underside of the Klein85ooth in a known manner, and therefore shown only schematically.
  • the air follows the arrows A on all sides to the edge of the bottom element 4 and then rises through vertical channels 8 on the outside of the combustion chamber 2 upwards. From the vertical channels 8, the combustion air then passes through all slots 6 in the combustion chamber 2, so that in any case by the generous dimensioning of the cross section of the channels 8 and the slots 6 combustion air surplus in the combustion chamber 2 can be achieved, the complete, low-emission combustion causes the fuel.
  • the sufficient cross sections can be achieved for example by spacers, which are provided or inserted at selected locations.
  • FIG. 1 A preferred embodiment of a building block 5 for the production of the side walls 3 of the furnace 2 after Fig. 1 show the Fig. 2 to 6 in detail.
  • the module 5 has a substantially rectangular cross-section, for example, with side lengths of 5 and 8 cm, so that - as the illustrations Fig. 7 to 10 show a thicker side walls 3 for larger combustion chambers and higher heat outputs, and can be achieved by a high-edge processing thinner side walls 3 for smaller fire chambers and lower heating capacities.
  • the blocks 5 are provided on two adjoining side surfaces 11, 12 with projections 9 and in the two other side surfaces 13, 14 with recesses 15, 16, 17.
  • the projections 9 are formed substantially truncated pyramidal with a rectangular base and extend with the shorter side in the longitudinal direction of the block 5, as seen from Fig.
  • each two projections 9 on each side surface 11, 12 corresponds to twice the width x, y of the side surface.
  • a button-shaped upper part 10 on the projection 9 is used in particular for forming a sufficient distance to the outer shell 1, by which the corresponding dimension of the vertical channel 8 is ensured.
  • the recesses 15, 16, 17 are formed in the side surfaces 13 and 14 in two different depths and orientations.
  • a shallower recess 15 is formed by a longitudinal groove in the side surfaces 13, 14, whose Width of the length of the projections 9 and whose depth is smaller than the height of the projections 9.
  • the deeper recesses 16, 17 are at least as deep as the projections 9 including the tops 10 up and provided in two rows, wherein in a first row are substantially truncated pyramidal recesses 16 provided with a rectangular base corresponding to the truncated pyramidal projections 9 on the opposite side surface, which thus extend in the longitudinal groove 15 with the longer side perpendicular to the longitudinal direction of the block 5 and to each other by twice the width x, y of the side surface 11, 13; 12, 14 are spaced from each other.
  • building blocks 5 are placed one above the other, then on the one hand the dense arrangement is possible, as is required, for example, for the formation of the ash space, since - as best of all Fig. 11 it can be seen - the projections 9 completely engage in the deeper recesses 16.
  • superimposed building blocks 5 by twice the width x, y of the side surfaces 11, 13; 12, 14 displaceable in length.
  • the second row belonging depressions 17 are also formed opposite to the projections 16, but rotated by 90 °, so that their longer sides of the rectangle in the longitudinal direction of the block 5 are. Due to the rectangular truncated pyramid shape they are narrower than the projections 9 and can therefore be provided at intervals in the side surfaces 13 and 14, which correspond to the width x, y of the side surface, since the projections 9 project beyond the recesses 17 on both sides. Thus, the blocks 5, offset by their width, can be superimposed so that the slots 6 remain free between the blocks 5 for supplying the combustion air, since the projections 9 abut outside of the deeper recesses 17 respectively in the shallower recess 15.
  • the deeper recesses 17 could also be performed by a continuous longitudinal groove within the shallower longitudinal groove.
  • the spaced arrangement of individual longitudinal deeper recesses 17 is advantageous because the outermost projection 9 of the overarching block 5 in the corner in the outermost deeper recess 17 of the vertically extending block 5 of the other side wall. 3 positively engages.
  • the blocks 5 of the side walls 3 are laid so that the arranged on the vertical side surface 11, 12 protrusions 9 including the tops 10 each project outwardly, so that the height of these projections 9, the distance of the side walls 3 to the outer shell 1 and thus this dimension the vertical channels 8 is determined.
  • the height of the projections 9 therefore depends on the amount of combustion air to be introduced through the slots 6 in the combustion chamber 2, and is in particular between 2 and 2.5 cm.
  • the depth of the deeper recesses 16, 17 is then preferably up to 2.6 cm, while the depth of the shallower recesses 15, that is, the longitudinal groove which determines the width of the slots 6, preferably at 1 cm.
  • the blocks may have predetermined separation marks in order to be able to break off at the corners resulting supernatants corresponding to the wall thickness or a multiple of the wall thickness in a simple manner.
