Combustion chamber shingle of a gas turbine

Abstract

Combustion chamber shingle of a gas turbine, including a bolt for bearing the combustion chamber shingle at the combustion chamber wall, wherein the combustion chamber shingle is formed substantially in a plate-shaped manner, and has at least one bearing element at one side, at which the bolt that is formed as a separate structural element is anchored in a form-locking manner, wherein the bolt, at its end area, is provided with a baring area that is arranged at a rectangular position to the bolt axis and that is arranged inside a recess of the bearing element, wherein the bolt has a centric passageway recess, and wherein the recess of the bearing element is dimensioned so as to be bigger than the baring area of the bolt, so that a hollow space is created between the surface of the combustion chamber shingle and the baring area of the bolt.

1 . A combustion chamber shingle of a gas turbine, comprising a bolt for bearing the combustion chamber shingle at the combustion chamber wall, wherein the combustion chamber shingle is formed substantially in a plate-shaped manner, and has at least one bearing element at one side, at which the bolt that is formed as a separate structural element is anchored in a form-locking manner, wherein the bolt, at its end area, is provided with a baring area that is arranged at a rectangular position to the bolt axis and that is arranged inside a recess of the bearing element, wherein the bolt has a centric passageway recess, and wherein the recess of the bearing element is dimensioned so as to be bigger than the baring area of the bolt, so that a hollow space is created between the surface of the combustion chamber shingle and the baring area of the bolt. 
     
     
         2 . The combustion chamber shingle according to  claim 1 , wherein the bearing element is provided with cooling holes. 
     
     
         3 . The combustion chamber shingle according to  claim 1 , wherein the recess of the bearing element is opened up laterally. 
     
     
         4 . The combustion chamber shingle according to  claim 1 , wherein the bearing element is formed in a bow-like or bell-like manner. 
     
     
         5 . The combustion chamber shingle according to  claim 1 , wherein the bolt can be inserted into the recess with the baring area in a direction perpendicular to the bolt axis of the bolt. 
     
     
         6 . The combustion chamber shingle according to  claim 1 , wherein, at the combustion chamber shingle, multiple bearing elements are formed, that have recesses which are formed in such a manner that they are opened towards different directions. 
     
     
         7 . The combustion chamber shingle according to  claim 1 , wherein the bearing element and/or the combustion chamber shingle is provided with effusion cooling holes in the area of the bearing element. 
     
     
         8 . The combustion chamber shingle according to  claim 1 , wherein the baring area is formed in a plate-shaped or bar-shaped manner. 
     
     
         9 . The combustion chamber shingle according to  claim 1 , wherein the bearing element is integrated in an edge board of the combustion chamber shingle. 
     
     
         10 . The combustion chamber shingle according to  claim 1 , wherein the bolt is formed as a threaded bolt.
