Refractory tiles and mounting methods

Abstract

A tile that has a channel that is sized and shaped to accommodate a bolt with a washer, and that extends from one side of the tile to a location near the center of the tile. The tile can be mounted solely with the bolts and washers, or with other support structures.

1 . A tile for use on a wall that has boiler tubes oriented along a first direction and that also has outwardly extending bolts that each have a first diameter and that extend away from the wall, the bolts having washers mounted on them, the washers having a second diameter greater than the first diameter, the tile comprising: 
 an inner side for facing the wall;    an outer side for facing an incinerator chamber;    at least one channel oriented along the first direction at the inner side and extending at least partly along the first direction length of the tile, the channel including: 
 a first portion with an outer region extending inwardly from the inner side and having a width greater than the first diameter and less than the second diameter, and an inner region spaced from the inner side by the outer region and having a width greater than the second diameter, the first portion allowing the tile to move along the first direction relative to a bolt with a washer but not allowing the tile to be removed from the wall in a second direction perpendicular to the wall, and  
 a second portion next to the first portion and having a width greater than the second diameter from the inner side so that the tile can be mounted to the wall in the second direction and the channel is large enough to receive the washer such that the tile can be mounted along the second direction over the bolt and washer and then moved in the first direction so that the bolt and washer are in the first portion of the channel, the second portion being located within the perimeter of the tile and not extending to an end of the tile;  
   the tile further including a first stopping location at the channel and over the second portion where the tile cannot move downwardly along the first direction relative to the wall when the tile is mounted over the bolt, thereby allowing the tile to hang on the wall with the bolts and without further support.    
   
   
       2 . The tile of  claim 1 , wherein the stopping location includes a passage that allows the washer to be accessed from a top of the tile for adjustment.  
   
   
       3 . The tile of  claim 1 , further comprising a second channel with a portion with an outer region extending inwardly from the inner side and having a width greater than the first diameter and less than the second diameter, and an inner region spaced from the inner side by the outer region and having a width greater than the second diameter, the first portion allowing the tile to move along the first direction relative to a bolt with a washer but not allowing the tile to be removed from the wall in a second direction perpendicular to the wall.  
   
   
       4 . The tile of  claim 3 , wherein the stopping location is between the first channel and the second channel.  
   
   
       5 . The tile of  claim 1 , wherein the tile is mounted to the wall mechanically solely with the bolts and washers.  
   
   
       6 . The tile of  claim 5 , wherein there are two and only two bolts and washers per tile.  
   
   
       7 . The tile of  claim 1 , further comprising mortar between the tile and the wall.  
   
   
       8 . The tile of  claim 1 , further comprising a material provided in a pourable form between the tile and the wall.  
   
   
       9 . A wall of tiles covering a wall with boiler tubes and including at least first, second, third, and fourth tiles arranged in a two-dimensional array of tiles that all have the same configuration, each tile including a channel including means for supporting the tile with two and only two bolts mounted to the wall and washers on the bolts such that can each supporting means supports the tile without a separate bracket or bracket tile.  
   
   
       10 . The wall of tiles of  claim 9 , wherein the tiles are arranged so that each has a gap along two orthogonal axes relative to adjacent tiles, the gap being sufficient to provide an expansion material between the tiles.  
   
   
       11 . The wall of tiles of  claim 9 , wherein the means for supporting includes a portion of the tile extending across the channel over a point where the bolts are located when the tile is mounted on the wall so that the bolts are in contact with that portion to prevent downward vertical movement of the tile relative to the bolt.  
   
   
       12 . The wall of tiles of  claim 9 , wherein each tile has means for allowing access to the washers from the top of a first tile when there is no other tile mounted over the first tile.
