Definitions

  • the invention relates to an industrial furnace with a circumferentially curved, multi-layered inner wall, at least its convexly curved lining layer interlocking with each other, having refractory shaped stones.
  • the damage can reach a level that is an early renewal of at least the convex outer layer of the inner wall required power.
  • concave lining layer of the inner wall lead the Thermal expansions to a stabilizing tension of the structure.
  • the invention has for its object to avoid the disadvantages mentioned and thus a To find industrial furnace, which increased durability of its refractory lining and so that has improved reliability.
  • the solution of this task is carried out according to the invention in that the convex lining layer formed by shaped blocks is in Circumferential direction formed by at least one of refractory concrete elements, a Expansion joint having compensating area is interrupted, wherein the refractory concrete elements are molded to the adjacent shaped stones, so that they in their tooth profile engage and anchored by concrete anchors to an inner layer of the inner wall.
  • the hanging arrangement of the inner wall 4 shown as an exemplary embodiment has a metallic, inner carrier layer 5 with air-flow cooling channels 6. At its lower end goes they are in a holder 7 for a lower, cast from refractory concrete support ring 8 via.
  • the inner carrier layer 5 is protected on both sides by insulating layers 9,10.
  • the Lining layer 11 interrupted by at least one compensation area 15-18, of which in the embodiment according to the representation in Fig. 2 in the circumferential direction uniformly four are provided.
  • Each equalization area 15 to 18 has two as shown in Figs. 4 and 5 between an expansion joint 19 enclosing concrete elements 20,21, in the circumferential direction are positively connected with the waisted formed adjacent form stones 11 and which are further characterized by several, e.g. bifurcated concrete anchors 22,23 on the metallic support layer 5 are attached. They have a flat cross section, so they only in one direction are compliant and rigid in the vertical direction so that they are the concrete elements 20,21 in its vertical position.
  • waisted shaped blocks 11 hold the concrete elements 20,21 of the four compensation areas 15 to 18 thus the one running between them in an arc of 90 °, convex or arcuate lining sectors 24 to 27 in the manner of a yielding Abutment on the inner, metallic carrier layer 5, so that detachments and local Overloading of the lining can be prevented.
  • the size of the compliance of the compensation areas 15 to 18 is determined by the width of the expansion joint 19 determined.
  • this width of the expansion joints 19 is designed so that they are at Reaching the operating temperature of the furnace at least completely close or beyond allow in the lining sectors 24 to 27 a pressure build-up, so that when cooling First, this pressure is dissipated before shrinking and relative movements in the furnace Structure of the molded blocks 11 are possible.
  • the concrete elements 20, 21 and 30, 31, respectively of the compensation area 15 the same radial width as the refractory shaped bricks 11 of convex lining layer 13, so that their concrete anchors 22,23 by the inwardly adjacent Insulate layer extend and thus perform in this unimpeded bending movement can.
  • the concrete elements 32, 33 extend with one a part of the concrete anchors 22,23 including web 34,35 to the metallic support layer 5 on and thus enclose a space filled with insulating material space 34th für these webs 34,35 are the concrete anchors 22,23 stiffened, so that in the lining sectors 24 to 27 with closed expansion joint 19 can form greater compressive stresses than at the embodiments of Figure 5 and Fig. 6.
