Definitions

  • the present invention relates to protection against corrosion and erosion of the pressurized parts, and more particularly of tubular beam screens of the combustion chambers of boilers. This invention applies more particularly, without being limited to this application, to the protection of the combustion chambers of boilers equipping incineration plants with household and industrial waste.
  • the present invention proposes to provide a device eliminating the drawbacks mentioned above by ensuring the maintenance of the coating of refractory concrete along the stop line, in the lower part.
  • the device according to the present invention is essentially characterized in that it comprises refractory elements based on silicon carbide, of small size, hooked to the tubes of the tubular panels by a single point, in order to allow free expansion.
  • each refractory element is provided with a housing of appropriate shape to the right of the attachment to the tube cor corresponding, this attachment being achieved using a lug of suitable shape, positioned in said housing and welded to the generator of said tube or on the fins of the tubular panels.
  • each of said refractory elements made of silicon carbide is partially embedded in the tube or tubes to which it is fixed.
  • the device according to the invention is placed in the lower part, along the line on which the refractory concrete ends.
  • This device essentially comprises refractory elements made of silicon carbide, such as 18, of small dimensions, hooked to the tubes 12 by a single joint, thus allowing free expansion.
  • the refractory elements 18 are partially embedded in the tube or tubes to which they are fixed.
  • each refractory element 18 there is provided a housing 22, of suitable shape, arranged in line with the fixing of the tube, this housing being designed so as to receive a lug or the like welded to the generatrix of the tube.
  • the tab 24 is welded to the tube 12, then the refractory element 18 is plugged into the tab. It is then possible to fix a retainer at the end of the tab, the latter being protected by a cap sealing the housing 22.
  • the refractory element is hung on the fins 14 of the tubes by an iron 28, welded to the corresponding fin.
  • the iron 28 is welded to the tube 12.
