Definitions

  • the invention relates to a grate furnace for the combustion of household waste, similar to household waste and paste waste, to which the combustion air for the combustion of waste is fed horizontally. Since a uniform combustion of the garbage on the incineration grate is sought, also in the case that the garbage whether dry or moist, a forced air-cooled grate bar shape has been chosen according to the invention, which optimally supplies the combustion air by means of air nozzles or air slots for the combustion of the garbage becomes.
  • the previously mentioned disadvantage of such grate furnaces for refuse boilers is avoided by using grate bars with forced air cooling as a closed combustion grate without stomata, the combustion air being uniform over the entire grate width, primarily through the arranged air nozzles or air slots on the grate bar lugs, the Garbage is fed horizontally and an optimal combustion and burnout of the garbage on the grate ensures picture 3. Further features of the subject matter of the invention result from the exemplary embodiment described below.
  • FIG. 4 shows a grate furnace for waste boilers according to the invention in a vertical longitudinal section.
  • the combustion chamber 2 Below the combustion chamber 2 is the combustion grate with the individual grate bars 1, on which the garbage 3 or the like is filled, the combustion air via the air distribution boxes 4, which are accommodated in ash funnels 7, through the forced air-cooled grate bars horizontal 5 and 6 for the combustion from garbage or the like.
  • a grate bar Figure 5 and several grate bars are shown assembled to form a dense grate surface without the formation of a gap between the individual grate bars Figure 6.
  • air channels 3 and 4 are attached for cooling the grate bar 1, which at the end of the lugs 2 and 2a, with air nozzles or air slots 5 and 6 are provided.
  • the air nozzles or air slots directed towards the sliding surfaces 9 and 10 or 13 Fig. 6 feed the combustion air horizontally across the entire grate width 14 Fig. 6 for the incineration of waste.
  • the sliding surfaces are cooled by the air ducts, which guide forced combustion air, thereby keeping the grate bar temperature very low and thus preventing metal build-up.
  • the individual grate bars are provided with holes 7 Fig. 6, which are screwed together by means of bar anchors to form a grate flat surface without gap formation between the individual grate bars, which enables the desired combustion of paste waste, which is not possible with conventional grate bar shapes.
