Definitions

  • the invention relates to a furnace with a ceramic furnace jacket, which encloses a furnace and a helical flue gas flue and is built from the height one above the other, the respective cross-sectional shape of the furnace has shaped stones, which have opposite centering shoulders on their facing end faces, the The lowest shaped block consists of a floor pan that can be supported on a pedestal and the uppermost shaped block consists of a cover provided with a flue pipe connection, while the intermediate shaped blocks are essentially of identical shape, at least in groups, and a fire-proof insert is inserted in a form-fitting manner in the area of the combustion chamber.
  • Tiled stoves offer significant advantages over other heating stoves in terms of firing, heat storage capacity and heat dissipation, which, however, have the disadvantage that the tiled stoves must be built on appropriate foundations.
  • the setting of tiled stoves consequently requires not only a considerable amount of work, which requires special expertise, but also a corresponding use of costs.
  • the firing chamber itself is formed by the shaped stones itself, which are only supplemented with a positively inserted rear wall, which entails the risk of mechanical damage to the shaped stones, for example due to inserted fuel.
  • the angularly offset arrangement of the inlet and outlet openings of the flue gas chambers formed by the shaped blocks enables a helical flue gas flue to be obtained with a length that is greater than that of a straight flue gas flue, but this length gain is hardly useful for better heat utilization, because of the Displacement of the inlet and outlet openings by a maximum of 90 ° for a full turn, at least four stacked stones are necessary.
  • the invention is therefore based on the object to avoid these deficiencies and to improve a furnace of the type described in such a way that a continuous flue gas flow which is advantageous for heat transfer can be ensured while maintaining simple setting work despite a flue gas flue comprising several turns, whereby on the one hand due to this flue gas flow the soot deposition is largely prevented and on the other hand the flue gas duct can be easily cleaned due to the furnace construction.
  • the invention solves this problem in that the shaped stones in their mutually facing end faces have an annular groove covered by the respective subsequent shaped stone for receiving a refractory sealing cord, that the refractory insert encloses the combustion chamber and that the shaped stones above the refractory insert each have at least one Form the core surrounding the turn of a helical channel for the flue gas duct.
  • the insert according to the invention fulfills a protective task for the molded blocks against mechanical damage, because the insert surrounding the combustion chamber forms a kind of lining for the molded blocks.
  • a sufficiently large heat exchange surface between the flue gas and the shaped blocks is required.
  • these requirements can be met very advantageously, the flue gas flue being able to be extended by one further turn each time new flint blocks are placed, so that good adaptation to the flue gas temperatures is possible .
  • the helically wound, core-enclosing channel for the flue gas flue also has the advantage that there are no dead spaces supporting soot deposition within the flue gas flue, which on the one hand considerably extends the operating times between two necessary cleaning operations and on the other hand significantly simplifies the cleaning work.
  • the uniform and rapid heating of the shaped blocks of the flue gas flue can additionally be increased in that the shaped blocks forming a turn of the helical channel have an axial through opening that can be closed with a lid in the core enclosed by the turns of the channel.
  • a central channel is obtained which can be closed at the top by a cover, so that the heat accumulating in this channel can be absorbed by the core of the shaped stones.
  • the heat exchanger of a low-temperature heating for example an underfloor heating system, can be used in order to make further use of the sensible waste heat of the flue gases.
  • the shaped stones in the area of the insert surrounding the combustion chamber have an axial groove that is open towards the insert and connects to an air supply duct in the area of the floor pan, then the fuel that is possibly discharged from the combustion chamber with the flue gases can be properly re-burned be taken care of because fresh air can be directed into a post-combustion chamber via the axial groove. Since all shaped stones in the area of the combustion chamber have this axial groove, the fresh air duct formed by the axial grooves is automatically extended with each additional shaped stone.
  • the insert surrounding the combustion chamber can consist of mutually supporting wall plates lying against the shaped blocks, which are kept at a distance from one another by means of a base plate and a ceiling plate separating a post-combustion chamber from the combustion chamber and leaving open fire openings.
  • the panels of the insert which only have to be inserted or inserted into the already staggered stones of the furnace, not only result in a smooth-walled lining of the furnace, but also serve to stiffen the stones, which enforces the necessary safety for the furnace.
  • the face sides of the shaped stones can be glazed, the design of these face sides. is completely free. It is therefore possible to achieve special architectural effects by laying the same shaped stones on top of each other, but with different sides.
  • the furnace shown has a furnace jacket made of prefabricated shaped blocks which have the respective cross-sectional shape of the furnace and are placed one above the other.
  • the lowest shaped stone 1a forms an ist on a base 2 supported floor pan on which the firing chamber 3 enclosing stones 1b are placed.
  • the shaped blocks 1c forming a channel 4 for the flue gas flue, which in turn have the same shape as one another, rest on these shaped blocks 1b, which are identical in shape to one another.
  • a lid is placed as the uppermost shaped stone 1d, which is provided with a smoke pipe connection 5. In this smoke tube connection 5, a smoke tube 6 is inserted in the usual way.
  • the shaped blocks each have mutually opposite centering shoulders 7 on their mutually facing end faces, which interlock when the individual shaped blocks are placed one on top of the other.
  • an annular groove 8 is arranged in the mutually facing end faces of the shaped stones, into which a refractory sealing cord 9 can be inserted, which is also received by the annular groove 8 of the immediately adjacent shaped stone.
  • a refractory insert 10 is inserted in a form-fitting manner in the shaped blocks 1b.
  • This insert consists of four wall panels 11 a and 11 b, of which the opposing wall panels 1 ia are pressed by the wall panels 11 b against the shaped blocks 1.
  • a floor plate 12 inserted into the floor pan 1a and a ceiling plate 13, which projects with a shoulder between the wall plates 11, provide appropriate support for the wall plates 11b, so that a self-stiffening system is achieved without the need for special connecting means.
  • the ceiling plate 13 of the insert 10 divides the combustion chamber 3 from a post-combustion chamber 14, which is connected to the combustion chamber 3 by fire openings 15.
  • axial grooves 16 are formed in the shaped blocks 1b, which form a fresh air channel, which has a groove provided in the floor pan 1a 17 is connected to a supply air duct 18 in the region of the furnace door 19.
  • the lowest shaped block 1a has a corresponding recess, which continues into the overlying shaped block 1b, so that the furnace door 19 is first inserted into the recess of the lowest shaped block 1a and then on the floor pan molded block 1b can be placed over the furnace door 19.
  • the shaped blocks 1c each have a turn of the helically extending channel 4.
  • the flue gas openings are flattened in the region of the undercuts which would otherwise result, as is indicated in FIGS. 1 and 2.
  • the shaped blocks 1c also have an axial through opening 20 within the core enclosed by the turns of the channel 4, so that a central channel results within the stacked shaped blocks 1c, which can be closed with the aid of a cover 21 in the uppermost shaped block 1c. Hot gas can rise from the afterburning chamber 14 in this central channel, as a result of which the core of the shaped blocks 1c can be heated more rapidly and uniformly.
  • the turns of the channel 4 for the flue gas flue need not be circular in cross section.
  • the flue gas flue could also be formed by a spiral surface starting from a ker, which extends over 360 ° for each shaped block 1c.
