Definitions

  • the invention relates to an industrial furnace having a furnace structure with an industrial furnace support structure.
  • Industrial furnaces with an industrial furnace support structure are used in various applications, such as lime kilns, in particular lime shaft kilns, glass furnaces, etc.
  • These support structures generally have a support element.

  • a support element for example, abutment stones (20.1 ', 20.2') and between the abutment stones arranged support arch stones (30), consist, which together form a vault-like support sheet (15 ').
  • the problems mentioned occur more frequently in connection with large support / support arch spans, for example for support bows with more than 3 m or 4 m span.
