Definitions

  • Lining for a combustion chamber that is at least approximately round in cross section
  • the invention relates to a lining for a combustion chamber which is at least approximately round in cross section / which is divided into at least two layers in the radial direction and at least two sections in the axial direction, with a seal made of metallic material as a gas seal.
  • the layers of such linings are made of different materials, which are selected in accordance with the temperature stresses and the expected thermal expansions in the respective layer. It is known to provide gas seals between the sections of such a liner extending in the axial direction, which are intended to prevent gases from entering the rear layers of the liner in an uncontrolled manner due to pressure differences and damaging the liner. Such damage can be caused mechanically by the formation of channels or other cavities. Damage due to chemical reaction is also conceivable. These gas seals are also called gas barriers.
  • the gas seals made from sheet metal were previously one-piece in the horizontal direction. Therefore, different thermal expansions of the individual lining layers in the axial direction in the area of the gas seals could not be compensated for, or only insufficiently.
  • a further disadvantage was that the one-piece gas seals in the radial direction made it difficult, for example, to replace only the inner layer of the lining and / or that the gas seals were not only partially replaced in a damaged area.
  • the gas seal is designed as a film and is divided in the radial direction into at least two parts which are detachably connected to one another in a manner that enables the removal of the inner part in the axial direction.
  • a gas seal made of foil can adapt to the thermal expansions in the different radial areas of the lining much better. This eliminates the risk of excessive stress on the gas seal and the formation of cracks.
  • the individual parts of the gas seal can also be
  • OMPI * due to the low material thickness of the film, simply connect by folding, bending or similar overlaps so that the overall thickness of the gas seal does not become too great in this connection area either. Thermal expansion of different magnitudes can also be compensated for in such a connection area. Due to the detachable connection of the gas sealing parts, assembly or replacement in the event of repairs are also made easier, for example when only part of a lining layer has to be replaced.
  • the subdivision of the seal into border regions between two adjacent layers of the lining is advantageously provided, since the seal can then be mounted or replaced together with the respective lining layer.
  • the seal be divided in the circumferential direction into a plurality of sector-shaped parts which overlap with one another in the region of their radial edges. This ensures that there is good adaptability of the seal to the thermal expansions that occur in the circumferential direction. It is advantageous according to the invention if one of the two edges of a sector-shaped part lies above and one edge below the edge of an adjacent part and if at least one of the sector-shaped parts overlaps the adjacent parts with both edges. This makes it easy to mount the seal over the circumference of the lining.
  • connection area between two parts of the gas seal is thus in one between two adjacent layers of the plane extending clothing and remains accessible even after the attachment of a further axial section of the lining, it also being advantageous that the connection area of the sealing parts is not directly loaded by the weight of the next section of the lining. It is favorable also in this hang Caribbean ⁇ when the bent-over strips of two benach ⁇ barter sealing parts protrude into 'a formed between the layers of the lining gap z. B. can be formed by a mortar joint. This ensures that there is sufficient space in each case in the radial direction to accommodate the connection area between two sealing parts.
  • the pocket is assigned to the outer sealing part and is angled upwards in the axial direction and that the axial strip of the inner sealing part can be pulled down out of the pocket.
  • the free edge of the strip inserted into the pocket can be folded by approximately 180 ° to form a sealing lip.
  • a sealing part can be composed of a ring segment extending in the radial direction and a strip extending in the axial direction, which are connected to one another by folding. This enables a better adaptation of the film material to the arcuate course of the lining cross section.
  • the outer edge of the seal can in each case be arranged between a support ring and a retaining ring which are screwed together or connected in some other way.
  • the layers of the lining can also be mounted in sections on a ring console, the outer edge of the seal being held clampingly between the lining and the ring console.
  • FIG. 1 shows a schematic longitudinal section through a furnace with a three-layer lining
  • FIG. 3 shows a top view of the gas seal in the region of a lining layer, seen in the axial direction;
  • FIG. 4 shows the gas seal according to FIG. 3, seen in the radial direction
  • connection area between two parts of the gas seal 6 in a modified embodiment the connection area between two parts of the gas seal
  • FIG. 8 shows a further modified embodiment of the gas seal in the adjacent area between two layers of the lining
  • a furnace which here has the form of a pressure reactor and is used to gasify carbon-containing material, will be described with reference to FIG. 1.
  • Average temperatures of up to 1100 ° C. occur here, but peak values of up to 1500 ° C. can be reached.
  • the operating pressure will generally be between 10 bar and 30 bar, although maximum values of over 100 bar are possible.

  • the pressure reactor has an outer steel jacket 10 and a lining which is made of refractory building materials and forms three layers 11, 12 and 13. Each of these layers 11, 12 and 13 is the length of the pressure reactor, i. H. in the axial direction, divided into two sections, one of which lies above and the other below a gas seal generally designated by the reference number 14. Since the gas seal 14 has the task of preventing the penetration of gas into the outer part of the lining due to pressure differences that can occur between the lower and the upper part of the interior 15 during a reaction process, additional gas seals 14 are made as required must also be arranged in the higher area of the pressure reactor if such pressure differences are also to be expected there.
  • the gas seal is formed in the radial direction by three sealing parts 16, 17 and 18, of which the sealing part 16 between the two sections of the layer 11 adjoining one another in the axial direction, the part 17 between the two in the axial direction In the direction of adjoining sections of the layer 12 and the part 18 between the two axially adjacent sections of the layer 13 of the lining is arranged.

  • An annular seal 29 is inserted between the sealing part 18 and the support ring 19.
  • On the top of the sealing part 18 is a retaining ring 21 which is screwed to the support ring 19.
  • the sealing part 16 is designed such that the sealing parts can be separated from one another by pulling them off in the axial direction. If, for example, you only want to replace the lower section of the inner layer 11 of the lining, the sealing part 16 can be changed according to the pro i ⁇ ⁇ ⁇ -
  • OMPI Remove the soric catch of the upper section and the removal of the lower section of the layer 11 and replace it with a new sealing part 16 if necessary.
  • the overlapping strips 16a and 17a or 17a and 18a also allow different thermal expansions to be compensated for in the axial direction.
