Definitions

  • the invention relates to a combustion chamber for an incineration plant, in particular a waste incineration plant with side walls through which air flows, which are supported by a scaffold, sealed to the outside by a sheet metal jacket and to the inside are delimited by plates suspended from one another with the formation of air outlet openings.
  • Such plates are mainly used in waste incineration plants in the grate area of the boiler.
  • the air escaping between the plates prevents slag deposits from forming on the walls.
  • incinerator In a known incinerator (DE-B-2 317 064) a wall made of metallic plates is hung in the grate area in front of the air outlet openings in the inner sheet metal jacket of the cooled cavity wall, between which air passage gaps are formed. If the air supply fails unexpectedly in such a system, there is a risk that the temperatures prevailing in the incinerator will corrode the metal plates unless a correspondingly expensive, heat-resistant material is used. In addition, the plates are relatively heavy and require a corresponding supporting structure.
  • the perforated plates are relatively complex to manufacture, assemble and weigh.
  • the invention has for its object to provide a furnace of the type mentioned with such plates that have a relatively low weight, are heat-resistant and easy to attach and replace.
  • the plates consist of a ceramic material, have molded cams on their upper edge, that brackets are attached to the frame, the vertical spacing of which is less than the height of a plate and that the plates are hung with the cams on the brackets and are supported in the area of the lower edge on the brackets below.
  • Such plates are characterized by a relatively low weight and increased heat resistance due to the material used.
  • the design of the plates and the brackets allows easy assembly.
  • the advantages associated with the avoidance of approaches of an air-cooled wall with air outlet openings are retained.
  • the wall remains relatively cool, so that no hot ash particles that are already in the pasty state can accumulate.
  • the air flowing through, the speed and quantity of which can be varied and can be adapted to operational requirements, prevents heat build-up on the walls. The heat absorbed is returned to the combustion process.
  • FIG. 1 The combustion chamber of the incinerator is shown in FIG. 1 of a waste incineration plant.
  • the furnace is delimited by a furnace grate 1 designed as a roller grate, by air-cooled side walls 2 and by a ceiling 3.
  • a waste heat boiler (not shown) connects to the furnace.
  • the side walls 2 consist of a supporting structure which is formed by vertical supports 4 which are connected to one another by horizontal supports 5.
  • the side wall 2 is sealed gas-tight to the outside by a sheet metal jacket 6, which is only partially shown in FIG. 2. This sheet metal jacket 6 is screwed or welded onto the supports 4 and 5 according to FIG. 2 for the interior of the furnace.
  • Ceramic plates 7 are suspended at a distance from one another at a distance from the sheet metal jacket towards the inside of the furnace. Between the sheet metal jacket 6 and the plates 7, a cavity 8 is formed, into which cold air is introduced via feed pipes 9. The air exits through the air passage slots 10 formed between the plates 7 into the combustion chamber of the incinerator.
  • Brackets 11 made of a highly heat-resistant, alloy cast material are used to suspend the plates 7.
  • the brackets 11 are screwed to the horizontal support 5. In this case, a vertical distance between the brackets 11 is maintained, which is less than the height of the plates 7.
  • the brackets 11 serve at the same time to suspend and support the plates 7. For this reason, sections of a U-shaped profile are advantageously used.
  • the U-shaped profiles are aligned so that their legs are on top of each other.
  • the ceramic plates 7 are preferably made of silicon carbide. They are provided with rear cams 12 on their upper edge. With this cam 12 engages the plate 6 over the lower leg 13 of the U-shaped profile serving as a holder 11.
  • the lower leg 13 is provided with a bead 14 adapted to the cams 12.
  • the lower edge of the plate 7 lies against the upper leg 15 of the holder 11, so that the pendulum-suspended plate 7 is prevented from retreating.
  • a hook 16 is passed between two plates 7.
  • the hook 16 is provided with a head 17 which overlaps two adjacent plates 7.
  • the plates 7 are provided with lateral recesses 18 which receive the head 17 of the hook 16.
  • the angled part 19 of the hook 17 engages in a slot 20 in the upper leg 15 of the bracket 11. Due to the suspension and attachment described, the plates 7 can be removed individually and replaced with new ones without the adjacent plates having to be removed or changed.
  • the upper and lower edges of the plates 7 are chamfered at the same angle. Together they form an obliquely downward air outlet slot 10. This downward air flow is intended to prevent dust from entering the cavity 8 within the side wall 2.
  • the air-filled cavity 8 between the plates 7 and the sheet metal jacket 6 is divided into horizontal sections by separating plates 21 which rest firmly on the brackets 11. As shown in FIG. 3, each of these sections is connected to an air supply pipe 9. In the same way, vertical sections with air can also be formed by installing vertically arranged dividing plates.
  • the cavity 8 can also be divided into horizontal and vertical sections by dividing plates 21 arranged horizontally and vertically.
