Definitions

  • the object of the invention is therefore a method of constructing the concrete casing of a chamber furnace which very greatly reduces the deformations due to the differential thermal expansion between the various elements of the furnace and to the thrusts of all kinds which are exerted on the walls.
  • Figure 2 which is a very simplified cross section, we has shown, in thickened lines, the concrete webs 11 which constitute the framework of the furnace, which is supported by a raft 12 resting on piles 13, the depth of which depends on the nature of the terrain T.
