Definitions

  • the invention relates to a refractory ceramic plate and an associated wall structure for one Incinerator, for example a Incinerator.
  • the wall structure includes a (mostly metallic) Furnace wall in which a plurality of tubes are spaced are arranged to each other, which are in operation by a Fluid, mostly water, are flowed through.
  • Anchors are attached to the furnace wall, which are essentially protrude vertically from the furnace wall and one Reinforcement function in one against the furnace wall ceramic mass to which the furnace interior connect fireproof ceramic plates.
  • Both the refractory panels and the ones behind arranged mass should have good thermal conductivity have heat from the furnace interior to the fluid to flow through pipes.
  • the heated fluid will for steam and / or electricity generation or for Heating purposes used as secondary energy.
  • the known wall arrangement meets these requirements.
  • the object of the invention is a possibility to show how a wall structure of the type mentioned in terms of its heat conduction to different Purpose can be customized.
  • the Wall structure Changes in length of the panels with changing Withstand temperature stress without any problems.
  • the oven room Adjacent plates are laid "floating". Your Fastening and alignment with one another takes place via the anchors.
  • the anchors are not flush corresponding recesses in the plates, rather is one around the corresponding sections of the anchors deformable, heat-resistant filling provided that the Compensation for changes in length under temperature load serves. The same applies to those in the joint areas arranged heat-resistant, deformable Leveling layers.
  • the distance between the plates and the Furnace wall can be set arbitrarily. In this way can the heat flow from the furnace to the pipes of the Set the furnace wall.
  • the distance of the plates to the furnace wall can alternatively or cumulatively also via spacers be defined as an integral part of the Plates can be formed.
  • the attachment of the plates to the anchors is special simple and allows easy and quick assembly as well as interchangeability.
  • the plate can extend any of its recesses have a blind hole, which the inclusion of a for example angled free anchor end is used.
  • the blind hole can be essentially parallel to the Main surfaces of the plate and therefore essentially run parallel to the furnace wall. That way you can the panels can be easily mounted parallel to the furnace wall.
  • the recesses can be completely in the range of one Main surface of the plate. It is also possible to design the recesses so that they are Continue in the edge area of the plate. This Embodiment is shown in the following Description of the figures explained in more detail.
  • the panels can then be placed on the side angled anchor ends and - depending on geometric design of the anchors - vertically into the final location will be postponed.
  • a deformable compensation layer can be arranged between corresponding edge areas of adjacent plates.
  • a Embodiment of the plate provides this Provide a leveling layer already on the plate.
  • one Main surfaces can, for example, in this way two adjacent edge areas of the plate are pre-assembled.
  • the compensation layer can be made of a fiber material consist, for example, an insulation strip on the corresponding edge area (s) of the plate is (are) stuck on.
  • the joint area between adjacent panels can be filled with a compressed fiber layer after they have been laid.
  • a fiber mat or a fiber strip the thickness of which is above the joint width, can first be moistened and then (more easily) compressed so that it can be inserted into the joint (the gap). After or during drying, the fiber layer presses itself into the joint by expansion (due to the restoring forces of the fibers) and seals it.
  • the bulk density of the fiber layer can be increased to 2 to 3 times the original bulk density (eg 35-70 kg / m 3 ) during compression.
  • Crystalline fibers are particularly suitable, for example those based on aluminum oxide (for example 95% by weight Al 2 O 3 , 5% by weight SiO 2 ).
  • the cutouts in the plates can also be filled with fiber material in the same way. This joint formation can be implemented regardless of the above-mentioned applications.
  • the assembly can be further simplified and the assembly time be shortened when using anchors, the two Have arms that are in recesses of adjacent plates inlay. This way, with a single Anchor two anchor points, one each neighboring plates can be provided. This too will continue in the following description of the figures explained.
  • the plates can consist of a material based on silicon carbide and / or aluminum oxide, for example with the addition of Cr 2 O 3 . Both have good thermal conductivity, corrosion resistance and slag resistance.
  • the heat flow from the furnace to the tubes of the furnace wall can be adjusted via the material of the plates and their heat conduction.
  • the heat-resistant filling in the area of Cutouts can be made of a ceramic mass or fiber materials consist. Ceramic materials for this purpose can those based on silicon carbide, vermiculite, corundum and / or bauxite and are known as such (e.g. CARSITECT 170V from DIDIER-WERKE AG, Wiesbaden).
  • Figure 2 shows a plate 10 with two rectangular Main surfaces 10.1, 10.2, plan two side surfaces Edge areas 10.3, 10.4 and two graded upper and lower edge areas 10.5, 10.6.
  • the recesses 12.1, 12.2 and associated blind holes 14 serve to accommodate anchors that are related with the following description of Figure 1 in more detail to be discribed:
  • Figure 1 shows a wall structure, here for one Incinerator.
  • the wall structure comprises an oven wall 30 with a large number, parallel to each other arranged, through which water can flow 32 on both sides via the between adjacent tubes 32 protruding furnace wall sections 30.1.
  • each two arms 16.1, 16.2 have and substantially perpendicular to the furnace wall 30 run.
  • the free ends 16e of the armature arms 16.1, 16.2 are angled in opposite directions and reach into the cutouts 12.1, 12.2 explained with reference to FIG or with their free ends 16e in the associated blind holes 14 of the plates 10 a.
  • the remaining area of the recesses 12.1, 12.2 is with a heat deformable, heat resistant Filling 15, here a ceramic mass based Silicon carbide, filled, in which the anchor 16 with their Insert ends 16e.
  • a plate 10 is opened corresponding anchor arms 16.1, 16.2 held and aligned.
  • Several plates 10 are next to each other and assembled on top of each other to create a closed one Wall surface with flat parallel surface 10o for Form furnace interior 18 out. Stand there adjacent plates 10 at a short distance from each other, with the formation of appropriate joints 34 by a deformable, compressed insulation strips 36 ceramic fiber material are filled.
  • the arrangement of the plates 10 is between the Panel wall and the furnace wall 30 a cavity 38 trained who with a refractory casting compound Base aluminum oxide is filled and the Anchor arms 16.1, 16.2 covered.
  • the plates 10 and the mass located in the cavity 38 40 have good thermal conductivity and Corrosion resistance to aggressive gases.
  • the distance between the rear sides 10.1 of the plates 10 and the furnace wall 30 can extend the length of the armature 16 can be set. Alternatively or cumulatively, the Distance can also be set using spacers dotted in Figures 1 and 2 and with 10n Marked are.
  • the spacers 10n are here materially from the furnace wall 30 facing Molded surface of the plates 10 and lie against corresponding pipes 32.
  • Edge areas 10.5, 10.6 of the plates should be flat. Any other geometry of the plates is also 10 possible.
  • FIG. 10 Another formation of panels 10 and joints 34 between plates 10 shows Figure 4.
  • Corresponding Surface sections 10.5, 10.6 of plates 10 are here formed in the manner of a tongue and groove connection, namely with tongue 10.5f or groove 10.6n in the area between corresponding main areas 10.1, 10.2.
  • the End face 10.5s of the spring 10.5f and the base 10.6b of the Groove 10.6n are with groove-like depressions 10.5v, 10.6v formed, which is a ceramic sealing cord 36d, while the remaining joint area 34 with a ceramic fiber material or an elastic ceramic putty 36 is filled in as above described.
  • This joint formation is independent of Possible scope described above.
