Gas turbine combustor with tile having access hole for spark plug

Abstract

The present invention relates to a gas-turbine combustion chamber with a combustion chamber wall, on which tiles are arranged, and with a recess for passing through an igniter plug, said recess extending through the combustion chamber wall and a tile, with the tile being provided with a tubular projection surrounding the recess and extending from that side of the tile facing away from a combustion chamber interior.

1 . Gas-turbine combustion chamber tile with a recess for passing through an igniter plug, wherein the tile is provided with a tubular projection surrounding the recess and extending from that side of the tile facing away from a combustion chamber interior. 
     
     
         2 . Tile in accordance with  claim 1 , wherein the projection is designed in one piece with the tile. 
     
     
         3 . Tile in accordance with  claim 1 , wherein the projection is provided at its free end area with an igniter plug seal. 
     
     
         4 . Tile in accordance with one of the  claims 1 , wherein the projection is provided with an annular contact surface on its outer circumference. 
     
     
         5 . Tile in accordance with  claim 1 , wherein the projection is provided with at least one cooling air recess extending through the wall of the projection. 
     
     
         6 . Tile in accordance with  claim 1 , wherein the tile with the projection is provided as a casting. 
     
     
         7 . Tile in accordance with  claim 1 , wherein the tile with the projection is manufactured by means of a laser deposition welding method. 
     
     
         8 . Gas-turbine combustion chamber with a combustion chamber wall, on which tiles are arranged, and with a recess for passing through an igniter plug, said recess extending through the combustion chamber wall and a tile, wherein the tile is designed in accordance with  claim 1 .
