This invention relates to a furnace wall having sections that are movable relative to each other and in which provision is ymade for preventing ash or cinders from collecting in the joint between the sections. The invention will be understood from the description in connection with the accompanying draw,- ings in which Fig. 1 is a side view, partly broken away, observed from the inside of the furnace; Fig. 2 is a vertical section, partly` broken away through the furnace wall; Fig. 3 is a perspective view of one of the special blocks or tile; and Fig. 4: is a perspective view of a support for the block or tile.

ln the drawings, reference character 1 indicates a section of a furnace wall which may be near the lower edge of the wall and may be stationary. Another section of the wall is shown above the section 1 and may be made up of a row of water tubes carrying blocks or tile, this section being supported independently of the lower section and free to move toward and away from the same due to expansion and contraction. rll`he tubes 2 of the water wall have their lower ends bent outwardly, as shown at 3, and are connected to a horizontal header 4.- on the outside of the furnace wall. Blocks or tile 5 are connected to the tubes 2 by clamps 6 with bolts 7 connecting the tile 5 and the' clamps in the well known way. The tile 5 may be made up with metal backs that have curved surfaces contacting with the tubes 2 and refractory face portions that are exposed tothe heat of the furnace.

The upper edge of the wall section 1 is` made sloping as indicated at 8 and a :flexible distance therefrom to permit expansion ofV the upper section of the wall. One of the supports 10 for the special blocks'or tile is 1 mostclearly shown in Fig. 4.. Each support 1s provided wlth curved portions 11 to be clamped into firm engagement with the tubes. A. plate 12 extends outwardly toward the inside of the furnace from the lower edge of the support 10 and the free inward edge of the plate 12 is provided with an upwardly extendmg lip or extension 13. An extension 14 that is T-shaped in cross section projects from. the face of the support 10 toward the inside ofthe furnace and is disposed in a vertically extending direction at an angle to the horizontal' when the support l0 -is in place.

@ne of the special blocks or tile 15 that is to be installed in the row near the upper edge of the section l of the furnace wall is most clearly shown in Fig. 3. Each one of the special tile or blocks 1s provided with a flat back portion that fits against the front face ofthe support 10. Each special block is of an approximate V-shape having a front face 16 that is vertical and in line with the inner face of the section 1 when the blocks are in place, as most clearly indicated in Fig. 2. The lower end of the block 17 is somewhat pointed and the bottom of the block is Hat and approximately parallel with the sloping surface 8 of the section 1 when the biocliis in place. A recess 18 is provided in the bottom of each block into which the corresponding plates l2 and lips 13 of the supports 10 iit when the blocks areinstalled. Each block is provided with a 'lV-shaped recess 19 into 'which the corresponding extensions 14 fit.

llt will be obvious from an inspection of Figs. 3 and 4f that the blocks 15 can be put in place on the supports 10 by moving the same downwardly Vfor the extensions 14 to t into the grooves 19 and the plates. l2 and lips13 tot into the recesses 18, thus holding the blocks securely in position by means of the supports 10, and at the same time making-it possible to remove them very readily for replacement when injured or' broken.

With the capor joint between the two sections of the furnace wall sloping downwardly, as most clearly shown in Fig. 2, it will .3c clear that any ash or cinders that may be ,caught in ythis space .will work downwardly and into the 'furnace as expansion andcon- Itraction take place between the sections, and

thatthedanger of the joint becoming permanently clogged with the ash and cinders is eliminated.

5 The upper surface of the blocks 15 may be made horizontal so that the next row of blocks may rest thereon, and the blocks that are attached to the curved portions of the tubes 2 may be so shaped that a flat surface is presented to the inside of the furnace.

I claim:

1. In a furnace, a wall section and a second wall section above said rst-named wall section, one of said wall sections being movable relative to the other, adjacent portions of said wall sections forming a space downwardly inclined toward the Jfurnace to prevent ash or clinker from collecting between said wall sections.

2. In a furnace, a wall section, and a second wall section above said first-named wall v section, one of said wall sections being movable relative to the other, one of said wall sections being water-cooled, adjacent portions of said wall sections forminga space downwardly inclined toward the furnace to prevent a'sh or clinker from collecting between said wall sections.

. 3. In a furnace, a wall section and a second wall section above said first-named wall section, one of said wall sections being movable relative to the other, adjacent portions of said wall sections forming a space downwardly inclined toward said furnace to prevent ash or @linker from collecting between said sections, the upper portion of said second wall section comprising. a block having a portion of its upper surface extending downwardly and inwardly toward the furnace.

' 4. In a furnace, a wall section, a second wall section above said first-named wall section comprising tubes and tile attached thereto, said wall sections being spaced apart'and independently supported, adjacent portions of said sections forming a space extending downwardly into a free space to prevent ash or clinker from collecting between said sec# tions, and means to prevent gas leakage from taking place through said space.
