Definitions

  • the invention relates to a grate brick for a stacking grate layers comprising a feed grate of a combustion plant, a grate stone layer and a feed grate according to the preamble of claims 1, 9 and 10, respectively.
  • Grills are used, for example, to absorb combustibles such as waste in a waste incineration plant and to transport them through the furnace.
  • the grates are made up of individual elements, the so-called rust stones.
  • the grate stones on a flat focal surface and are adjacent to each other under formation grate layer arranged to provide a transport and / or combustion surface for incineration.
  • Neighboring rust stones can be like from the DE 20 2014 009 257 U1 Applicant known for stability of the grate layer without locking elements such as rods, screws or the like are connected.
  • Vorschubrosten or stuntschubrosten (here consistently referred to as feed grate, which also includes a return grate) are several combustion surfaces thus formed stepwise vertically stacked with horizontal Offset are arranged and are moved by a feed mechanism of the feed grate horizontally relative to each other such that fuel supplied from above during the combustion process is pushed over the individual stages, until ideally only the non-combustible residues are discharged down from the feed grate.
  • parts of the burning material or combustion residues can get into the spaces between the rusting stones and get stuck there. This can block and break the rust stones.
  • Damaged rusting stones must be replaced quickly in order to avoid consequential damage to the feed grate. Therefore, in such a rust stone fractures stop the plant and the affected rust stone must be dismantled after cooling to replace the broken grate stone against a new one. Such downtime is expensive.
  • the invention is therefore based on the object, a grate for a superimposed rust stone layers comprehensive feed grate of a combustion system, a grate layer and a feed grate according to the preamble of claim 1, 9 and 10, which increased in simple and cost manufacturability Stability and life of the feed grate allow and contribute to a homogeneous firing.
  • a grate stone (used here interchangeably for grate stone, grate bar, grate shoe and the like) for a stacked grate layers comprehensive feed grate of an incinerator, comprising a front foot portion and an upper tread for the front foot portion of a grate stone of a higher arranged grate layer created in which the running surface has a contouring with a bulge and / or depression for deflecting the rust stone of the higher arranged rust stone layer during the advancing movement of the rust stone layers of the feed grate.
  • the contouring can have concavely curved areas and / or convexly curved areas.
  • a depression or an embossment is provided.
  • multiple recesses and / or embossments may form the contour of a tread.
  • the embossment and / or depression is advantageously designed arcuate and may front and / or rear side have a flatter and / or steeper rising edge to allow the deflection with the least possible mechanical stress of the grating stones.
  • it may also be provided that the foot section sliding over the contouring in the feed direction and against to provide the feed direction with a corresponding to the embossment, depression and / or rising edge sized Gleitabrundung.
  • the inventively designed grate stone can now be made thinner in the area of the burning surface with material savings than in the area of the tread, as thanks to deflection typical damage caused by Brenngut- and Brenngutschreibstand entry into the grate interstices are avoided.
  • a side locking device for locking with an adjacent grate stone as shown in DE 20 2014 009 257 U1 be known, said locking device according to the invention allows a vertical and / or Drehauslenkmos.
  • the grating stones in a grate layer and / or in a feed grate with grate stones according to the invention laterally and / or superimposed adjacent to each other with alternating contouring for opposing deflection of adjacent grate stones in the advancing movement. This creates a wave-shaped deflection movement.
  • An embodiment is advantageous as a turning stone, the both ends at both ends has a receptacle in front of the advancing device of the feed grate and a bulge or convexity and a depression or concavity.
  • only one type of grate stone is to be provided because it can be installed alternately with one side and the other side as an active tread in order to effect a movement directed against each other.
  • grate stone 1 has a front foot section 2, a firing section 3 for kiln and an upper tread 4 with a contouring 5 for the front foot section 2 of a higher arranged grate stone 1.
  • the firing section 3 here has a smaller material thickness than the tread 4.
  • the contouring is carried out here in the form of a convenient arcuate embossment 6 with respect to the tread 4 with optional front and rear rising edges 7 and 8.
  • the contouring is carried out with a suitably congruent recess 9.
  • the foot section 3 has in the feed direction 10 and counter to the feed direction 11 a corresponding to the embossment 6 or recess 9 and rising edge 7, 8 Gleitabrundung 13 on.
  • a lateral locking device 14, for example in the form of an upwardly open hook, for locking with an adjacent grate stone 1 may be provided, as long as it allows a vertical and / or Dreeschlenkterrorism the grate stone 1.
  • An in Fig. 3 upper grate layer 15 of a feed grate of an incinerator adjacent preferably has alternately contoured grate stones 1, which are also moved on the foot section 2 on adjacent adjacent preferably alternately contoured grate stones 1 along the feed direction 10 and thereby deflected vertically in opposite directions.
  • the tread 4 may successively have a bulge / indentation / indentation, see Fig. 4 (a) , with a substantially sinusoidal course. Possibly. If several passages and / or depressions are provided, with or without distance from each other, see Fig. 4 (b) , The embossment 6 and / or recess 9 can also be configured trapezoidal, see Fig. 4 (c) ,
  • a turning grate stone 1 see Fig. 5
  • both ends 17 receptacles provided for engaging in a feed device of the feed grate.
  • the embayment / depression are congruent to each other, the grate designed as a mirror image.
