Definitions

  • the present invention relates to protection against corrosion and erosion 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 which equip incineration plants with household and industrial waste.
  • the object of this invention is therefore to provide an improvement in the fixing of these refractory parts, in order to avoid corrosion.
  • this invention relates to improvements made to the protection and to the fixing of prefabricated refractory pieces mounted on the walls of the combustion chambers of boilers, characterized in that they consist of, cooling the attachment using tubes. placed in front of the wall of the boiler to be protected, the refractory protective parts being retained by the cooling tubes.
  • the thickness of the refractory pieces 16 ′, 16 "can be reduced, outside the area of attachment to the tubes 18.
  • the tubes 18, which secure the refractory pieces 16, 16 ', 16 " are cooled by the same fluid as the tubular wall 10 of the boiler (superheated water, water-steam emulsion, or steam They can be linked together by continuous or discontinuous elements, for example flat bars.
  • the space separating the tubular panel constituting the wall 10 of the boiler can remain free; however, it is preferable to fill it, either by giving the refractory pieces an appropriate shape (16 ", Figure 4), or by filling it with refractory clay 20 (Figure 2) based on silicon carbide, which ensures good resistance. the possible passage of combustion gases.
  • the weight of the refractory pieces is taken up from time to time by load take-up elements, which can possibly be combined with the plates which ensure the connection of the tubes 18 to the tubular wall 10.
  • the tightness between the various refractory pieces can be ensured by a layer of refractory rammed earth, and it can be improved by the creation of baffles, of the tenon and mortise type for example, between the pieces such as 16.
