Definitions

  • the invention relates to a method for repairing walls of an industrial furnace, in particular the heating walls of a coking battery according to the preamble of the main claim.
  • DE-A-3425851 discloses a method for the partial or complete renewal of heating walls of a coking furnace battery.
  • adjacent masonry parts are kept essentially at operating temperature; the masonry to be newly built is done in such a way that the truss walls are arranged according to the warm dimensions and that the necessary expansion joints of the runner walls are provided in the area of the binder heads and filled with a refractory fiber material.
  • the object of the invention is to design the repair in such a way that the furnace wall becomes completely gas-tight again over the entire repaired wall area, the work for this is easy, the preparations are simple and the means to be used are inexpensive.
  • the invention provides the features of the characterizing part of the main claim.
  • the features of the subclaims serve to improve and further develop the features of the main claim.
  • the advantage of the method according to the invention can be seen in the fact that the expansion of the masonry when it is heated is to be taken into account only to an extent that only an intermediate space between the old and the new masonry is to be formed, which is somewhat larger than the expansion of the heated masonry is. This means that there is no longer any precise calculation and execution of a joint between the old and the new masonry that corresponds to the warm dimension or the expansion or to the fact that in the space between the old and the new masonry ceramic fiber material is introduced, which closes any remaining joints between the heated old and new masonry.
  • the invention offers the possibility that the gas-tight sealing of the rotor wall, in particular by ceramic welding, which is described, for example, in DE-A-2053420, immediately after the heating of the adjacent wall sections, ie by welding the space between the old and the new masonry can be done.
  • the method according to the invention offers the possibility of being able to dispense with an exact and rectilinear or rectilinear limitation of the edge at least of the old masonry. This work can be done with a hammer and chisel; if necessary, the irregularly machined edge can be scratched after heating.
  • type-independent stones can be used for the new masonry, which are either always available or can be procured for a short time.
  • the truss walls 3 extend between the two walls, between which the heating cables 4 are formed on the one hand and the runner walls on the other.
  • the area 5 between the old masonry sections 6 and 7 has been freed from the defective masonry in the usual way, so that the area 5 laterally from the Edge edges 8, 9 of the old masonry sections 6, 7 is limited.
  • These masonry sections are inclined relative to the longitudinal center plane E of the rotor walls 1, 2 at an angle ⁇ such that the distance between the outer edges 10 of the area 5 is greater than the distance between the inner edges 11.
  • edge edges 8, 9 are created in a simple manner by means of a hammer and / or chisel, without attaining a specific configuration of the area 5.
  • a new masonry 12 is bricked up, which, as shown in the embodiment according to FIGS. 3 and 4, may also have an inclination directed towards the plane E of the runner walls 6 and 7, in such a way that between the edge edges 8 , 9 of the old masonry sections 6, 7 and 13, 14 of the new masonry 12 a V or wedge-shaped space 15, 16 is formed.
  • the spaces 15, 16 have an average width a and b, respectively, which is somewhat larger than the expansion of the masonry parts to be expected when they are heated.
  • the average distance between the edge edges 8, 9 and 13, 14 from one another is preferably approximately 50 to 100 millimeters.
  • the new masonry 12 can be designed with flat end edges, the individual layers of the new masonry 12 can be designed in steps. In this way, vertical steps 22, 23, 24 can be formed, the adjacent edge 8 of the old masonry sections 6 showing a vertical or approximately vertical course.
  • Masonry openings are also openings at the beginning and end of a runner wall.
  • the corner area is made of damaged, old masonry demolished and replaced by new masonry to form a space as described above, after which the old and new masonry are treated as described and the space is closed.
  • An advantage of the method is that the stones used for bricking up the new masonry part can be selected independently of the stone profiles of the old masonry. Since the spaces between the old and new masonry can be irregular, the position of the butt joints and bed joints of the new masonry 35 and 36 is irrelevant.
