7 Claims. (Cl.V 72-101) The present invention relates generally to wall construction for furnaces, and more particularly to a furnace wall construction of individual tiles supported in horizontal tiers in which the metal brackets are entirely outside of the plane of the wall proper.

In brief, the present novel wall construction comprises a plurality of selected variously formed refractory tiles 'which are supported in tiers by novel brackets. The novel brackets are removably mounted on vertically spaced horizontally disposed supporting members, the brackets on each supporting member being disposed in horizontally spaced relation. Each bracket supports a hanger tile through the medium of bosses, and each hanger tile receives in supported relation on additional bosses a pair of left-hand and right-hand foot tiles cooperatively formed to receive and to support filler tiles. These clusters of hanger supported tiles form a horizontal row, there being vertically spaced horizontal rows of such tiles supported by the hanger tiles. Between the horizontal rows of such yaforesaid tiles are additional tiles of selected shape which ll out the present novel wall construction. .Insulation is mounted behind the refractories in a manner enclosingveryY little of the metal work. The wail construction may be-repaired, or initially constructed from the outside. Y

There has long existed a need of a furnace wall construction such as that outlined in Vthe foregoing paragraph. While there are numerous furnace wall formations in'both Itile and monolithic refractory materials, there has existed the need for a furnace wall of tiered formation in which the metal supports are behind the wall in order Vto -aiford protection from the intense heat of the furnace, which will permit the use of a metal in the brackets of lower heat resistance characteristicsand, hence, of lower costs, which may be properly insulated without damage to metal parts, and which may be repaired from the outside.

Therefore,.an object of the present invention is to provide a novel furnace wall construction of tiered tileformation in which the metal brackets are disposed entirely rearwardly or outside of the wall, and which isinsulated.

Another object is to provide a novel furnace wall construction of tiered tile formation in which a worn or damaged Vtile may be replaced without the requirement of dismantling the whole wall, and in ,which such repair may be accomplished from the outside of the furnace.

Another object is toprovide a novel furnace wall construction of ltiered tile formation which is Ysimple to install and readily maintained.

Other objects and advantages are apparent from the following description taken with the accompanying drawings, in which:

Referring to the drawings more particularly by reference numerals, 26 indicates generally a furnace wall construction embodying the teachings of the present invention. Broadly, the furnace wall construction includes vertical H-beam supports 22, horizontally disposed and Avertically spaced bracket supporting composite members 24 which are supported by the members 22, hanger tile supporting brackets 26 mounted on the members 24, hanger tiles 28 mounted on the brackets 26, adjacently disposed rightand `left- hand foot tiles 30 and 32, respectively, hanging on the hanger tiles 28, ller tiles 34 lsupportingly wedged between each opposed pair of foot tiles 30 and 32, tiles 37 and 33, respectively, disposed beneath the bottom row of tiles 32 and 34, intermediate tiles 39 and 40, respectively, cap tiles 4i, and insulation 42. It `is to be understood, of course, that the furnace wall construction 2u of Fig. l of the drawings is only an illustrative s egment of a furnace wall, being all that is requiredto demonstrate the present invention.

The composite bracket supporting members 24`r`comprise channel Ymembers 44 and anglemembers 45 welded or otherwise secured together as clearly shown in Fig. 4, the composite member 24 being welded or otherwise secured to thevertical supporting members 22.

Each hanger tile supporting bracket 26 is preferably of the configuration clearly shown in Figs. 9, 10, yand il, and includes parallel Vspacedhook arms 48, anangularly disposed base or saddle portion 49, a horizontal foot 50, a vertically disposed foot .51, a vertical tin 52` which supports said feet Si) and 51 a notch 53 in the web '52, and opposed ilange portions 54 extending outwardly from the web 52 adjacent a majorportion of the notch 53.

The hanger tile 28 is preferably of the configuration clearly shown in Figs. 6, 7 and 8 in the drawings, and includes a main base por-tion 57 from both sides of which and in opposed relation extend a single rearwardly disposed boss 5% and a pair of forwardly disposed bosses 59. Included in the periphery of the main base portion Y57 are converging sides 6i). A

The left-hand foot tile 32 is preferably of the configuration sho-wn in the drawings, particularly Figs. L3 and 14, the right-hand foot tile 3% shown in Fig. 13 being the same as the tile 32 except vfor the hanger tile engaging portion. The tile 32 includes a hanger tile engaging portion 64 having a vertically disposed face in which are spaced wells 66 and an angularly disposed face 67 which is more particularly shown in Fig. 3. Forwardly of the hanger tile portion 64 is a -main body portion 68 having a transverse channel 69 in the top face thereof, and a deep notchz70 extending transversely across the bottom facetthereof.

The right-hand foot tile 30 is like the tile 32 except the hanger .tile portion Y64 faces in the opposite direction, hence, the several ,portions thereof have been marked with the same reference numerals as the tile 32, being primed to distinguish the two tiles. Y

-- The filler 4tilde 34 includes a Wedge-shaped-portionV 74 and a forward portion 75 the latter of which has a transryersenchannel-76 across the upper face thereof and a deep notchr'77 across the lower face thereof. Y

- The tiles 37 are of'sirnple rectangular form with a transversel ridge VS Vacross thetop surface thereof (Figs. l and 4). The tiles 38 are of the configuration clearly shown in Figs. 4 and 5 kand include a transverse channel 81 across the lower yface thereof and arpedestal or raised front portion 8,2. Y

The tiles 39 are relatively at and elongated, being of the configuration clearly shown in Figs. `l and 4, and each including a longitudinal channel' 8S along the upper sur- .facethereof and arvlongitudinal ridge 86 along the lower surfacethereof in superposed relation. The tiles 39 are of a Vlengthto'overlie one group of tiles 30, 32, and 34, as vistzlearfrom Fig.y Vl. The tiles40 are like the tiles 38 with the exception of including a transverse ridge S7 across the lower face in lieu of the transverse channel across the lower face of the latter. The pedestal portion of the tile 40 is designated 82. The tiles 41 are fiat, rectangular members, as is clearly shown in Figs. l and 4. .In the illustrative wall segment 20, the tiles 41 rest upon .the uppermost tiles 39 and a channel member-90 disposed across the tops of the supports 22.

The insulation 42 is placed between the refractories and the inner angeof the H-beam supports 22, so that .only a small portion of the brackets 26 are embedded. VHence, the structure is insulated without damaging the metal brackets. l

, Like other walls, the furnace wall 20 is normally conestructed of theseveral elements beginning with the bottom layer of tiles 31, after the metal framework is provided. I'hej succeeding layers of tiles are then built upon the tiles already inplace. However, it is to be noted that the f-construction is tiered and that the tiles 37 and 38 carry kno vWeightwith the exception of the fact'that the latter rest upon theformer. Each horizontal row of tiles 30, 32,and 34, which are supported from theV respective hanger lfiles 28 extending laterally fromand supported by the brackets 26, supports four layers of tiles V39 and a layer of tiles `40.

.lnj'order to facilitate sectional repairy of the Wall construction 20, a thick motar joint 92 is provided between the top of. each Ytile 3,8 and 40 and the bottom of the tiles -28, ,30, Y32 Vand V34, asis obvious from the drawings. Similarvertical joints may be provided if desired.

-The present wall construction 20 permits repair from the outside of the furnace, which is highly advantageous when the furnace space iszsmall or it is necessary to perform repairs when the furnace is running. Also, original :construction may be accomplished from the outside.

It is to be noted that the brackets 26 are behind the wall 20, and are so located in relation to the tiles that direct impingement of either ame or high heat is completevly avoided. The present tiered construction breaks up the overall expansion and contraction in the over-all wall area, and restricts these forces to the several tiers. In addition, the tiered formation renders repair easily accomplished and localizes the total Work required to replace damaged and .Worn tiles. A further advantage is the distribution of thel weight to therseveral brackets and supporting mem- `bers which substantially eliminates the possibility of the wall overturning, since the supporting brackets also function as anchors against such overturning.V Each bracket rmly engages its supporting member through the medium of the feet 50 and 51 and the notch 53, as is clear from Fig. 4. The flange 54 also contributes to stabilization of each bracket 26. A still further advantage is the insulation feature. In connection with this. feature, the

4 brackets 26 may be spaced further from the refractories, if desired. l

It is apparent'that there has been provided a wall construction which fulfills lthe objects and advantages sought therefor.

It is to be understood that the foregoing description and the accompanying drawings/have been given by way of illustration and example. YIt is also to be understood that changes in form-of the elements, rearrangement of parts, and substitution of equivalent elements, which will beobviousV to those skilled in the art, are contempla-ted as within the scope of the present invention which is limited only by the claims which follow. Y
