Definitions

  • the invention relates to a system for attaching refractory panels Boiler tube walls, in particular of steam generators and combustion plants, wherein the plates are held on metal tube webs between the Pipes are attached in particular welded.
  • the object of the invention is to provide a fastening system of the type mentioned to improve so that there is a secure hold with simple manufacture and the plates can be replaced individually with little effort.
  • each plate is individual for repairs interchangeable, without neighboring plates being moved or damaged have to.
  • the pipes are safely protected since the plates on their front are none Have openings and are therefore undamaged on the front.
  • the front is not broken through by holding elements in order to be subsequently sealed there be, so that additional wear in high heat and more corrosive Boiler atmosphere is prevented.
  • manufacture and assembly of the Bolts and plates simple and easy to carry out.
  • a secure and simple attachment is created by the fact that in the Blind bore inserting the front end of the bolt into two or more resilient Finger is split, which snapped into an internal extension of the blind hole lie.
  • a particularly secure hold is given if at least that in the blind hole Insert the front end of the bolt forward towards the plate opening inner cavity, in particular between the fingers, the can be filled with mortar or putty. It is particularly advantageous here if the Outside of the front end of the bolt in the area of the fingers in the Diameter tapers in particular towards the front.
  • a simple attachment of the bolts to the webs is achieved if that the rear end of the bolt is fastened in a hole in the tube web especially welded. It is particularly economical if the Bolts are shot into the bridge. This makes one special quick assembly achieved.
  • a boiler tube wall has numerous vertical tubes 1 which are the same Distances are arranged side by side, the tubes being separated by tube webs 2 are interconnected.
  • the metal tube rods 2 are on the tubes 1 molded or welded and lie in a plane that is also by the Pipe axes runs.
  • the bolts 3 are either on the webs 2 with their back ends 4 welded or in holes, not shown, in the Bridges 2 attached.
  • the bolts 3 are located centrally between two tubes 1.
  • the metal bolts 3 with their rear ends can also be used 4 are shot into the webs 2.
  • blind hole understood an axisymmetric opening, not by drilling, but is made of ceramic material during the molding of the plate.
  • the blind bore 6 has an inner extension 8 at its inner end, see above that its diameter is larger at the inner end than in the rest of the area.
  • the front end 5 of the bolt 3 is the outside corresponding to the inner Extension 8 shaped.
  • the front end 5 tapers, this conical taper 9 when entering the bore 6 on the outside Border edge meets a conical surface 10 through which the lower end 5 is compressible.
  • the front end 5 of the bolt 3 is in individual Split fingers 11, which extend axially parallel to the pin axis 12.
  • the front end 5 has a coaxial inner Cavity in the form of a blind hole that opens towards the front end 5.
  • the resulting cylindrical outer wall of the bolt 3 is through divided several longitudinal incisions 14 in the fingers 11. In Fig. 7 there are eight fingers 11 shown. However, this number can also be larger or smaller.
  • each plate is on the back covered with mortar.
  • This mortar also penetrates into the blind hole 6, so that when placing the plate on the bolt 3 of the mortar in the inner cavity 13 of the bolt penetrates and thus after the front end 5 has snapped in in the extension 8 of the mortar hardens and thus prevents the fingers 11 can move back inside.
  • This is a particularly secure hold the plates 7 on the bolt 3 and thus given on the pipe wall.
  • Bolts are thus dowels that penetrate into the pocket opening 6 of the plate, snap in and are secured against pulling out by the inner hardened mortar filling.
