FURNACE WALL..
Application mea :une 5, 1925. serial m. 35,150.
able front portion composed of elements which are combined with a 'permanent por,- tion of the wall in such a manner that they can be easily detached from said permanent portion when they become defective and replaced by perfect elements.-
Another object is to provide'a ventilated furnace wall that has a renewable front portion'of which is supported at numerous points throughout its area from the permanent back portion of the wall, thereby eliminating the p ossibilityof the front portion of the wall, which is subjected to the greatest heat, from breaking down or crumbling, as so often occurs in walls of the type in which the lower partof the front portion of the wall supportsand carries the entire weight of the` portion of the wall above it.
And still another object is to provide a ventilated furnace wall having the desirable characteristics above mentioned, that is inexpensive to build and easy to erect and repair. Other .objects and desirable features of my invention will be hereinafter pointed out.
Figure l of the drawings is a front eleva- .tional view of a ventilated furnace wall constructed in accordance with my invention.
Figure 2 is a horizontal sectional view,
taken on the line 2-2 of Figure 1.
Figure 3 is a vert-ical sectional view, taken on the line 3-3 of Figure 1.
' Figures 4, 5 and 6 are vertical sectional views, illustrating various ways of causing air to circulate through a wall of the construction shown in Figures 1 to 3.
Figure 7 is a front elevational view, illustrating a modification of my invention.
Figure 8is a vertical sectional view, taken on the line 8-8 of Figure 7 and v Figure 9 is a vertical sectional view,illus trating 'still another form of my invention. My invention is applicable to various kinds of ventilated furnace walls, such, for example, as the side walls and bridge wall of a boiler setting, and the elements which form the front face of the wall can be combined in various ways with the permanent back portion of the wall. In Figures lto 6 vof the drawings I havel illustrated lmy invention embodied in a furnace wall that comprises a permanent back portion A built of brick or any other-suitable material, and a A renewable front portion made up of relatively large tile B and B combined with said permanent back `portion A in such a manner that the renewable front portion of the wall is supported at numerous points throughout its area and is capable ot beiner rebuilt or repaired without disturbing sai back portion A. Preferably, the tiles B are provided on their rear sides with horizontally-disposed devices or slianks 1 that are interlocked with the permanent back portion of the wall in such a way that they can be easily detached from same, and the tile B are arranged in horizontal courses between the tile B, as shown in Figure 1, and are interlocked with each other and with said tile B by co-operating ribs andgrooves on the edges of said tile, as shown clearly in Figures2 and 3, lwherein the reference character 2 designates a horizontallyldisposed rib'on' the bottom edge of each tile that rejects into a groove formed inthe top et' ge of the adjacent tilefon whichit is superimposed, and the reference character 3 designates a vertically-disposed -rib on one side edge of each tile that projects into a groove inthe edge of the adjacent tile. The Shanks or rearwardly-projecting' devices 1 on the tile B are constructed so that they not only serve to detachably connect the renewable .front portion of the wall to the permanent back portion A, but they also sustain and carry the load'of said front portion or renewable portion and hold it spaced away from the back portion A so as to form ai-r ducts or passageways through which air is circulated' to prevent said renewable front `portion from becoming overhcated and in order to' obtain superheated air which can be introduced into the chamber o the fur-- nace above or below the fuelv grate, as indicated in Figures 2 to 6. So far as my in- 'one horizontal course of' tile C e uipped with horizontally-disposed slots 4 disposed to form substantially a continuous horizontal slot through which the heated air enters the furnace chamber from the air ducts or cil"-A culating passageways m behind the renewable front portion of the wall.
`As shown in Figures 2 and 3, the back portion A of the wall is provided with a pocket 5 for each of the shanks or rearwardly-projecting devices 1 on the tile B, and removable retaining elements 6 are arranged in. said pockets above said shanks, as shown 1n Figure 3, so as to prevent said/Shanks .from moving upwardly out of interlocking engagement with the permanent portion A of the wall. Various means can be used for-interlockino the tile vB with thepermanent portion of the wall so as to prevent said tile B from pulling away from the permanent portion of the wall, but in the form of my invention illustrated in Figures 1 to 6 eachv of the shanks `1 is provided at its outer end with a flared or substantially` dove-tail-shaped head 1a that fits in a correspondingly shaped recess in the permanent portion of the wall located below the pocket 5 previously referred `to, said recess being preferably formed by special blocks D built into the Apermanent portion A of the wall and provided with tapered surfaces that co-operate y with each iother, as shown in Figure 2, so as to form vertically-disposed slots of substantially the same cross-sectional shape as the Shanks 1 and the flared heads 1a on same. If desired, each of the blocks D can be provided on its front side with a forwardly-l projecting rib 7 that serv s as an abutment or bearing surface for two of the abutting tile B thatform part of the renewable front face of the wall, the rib 7 being so proportioned as to co-operate with the Shanks 1 and the tile B to form vertical diucts or passageways through which the air can circulate.
In erecting the wall the permanent back portion of the wall is first built of brick or any other suitable material and the special blocks D are incorporated in same so as to form a plurality of undercut recesses or openings in said permanent portion arranged below pockets 5 which are large enough to receive the flared heads 1a on the Shanks 1 of the tile B. In building the renewable front portion of the wall the tile B and B are laid up in horizontal courses and the Shanks 1 of the tile B are interlocked with the blocks D in the permanent portion A of the wall by introducing said Shanks horizontally intoi the pockets 5 and then moving them downpermanent portion A of the Wall.
wardly so as to insert thev flared or dovetail-shaped portions l of the shanks 1 1n the undercut recesses formed by the blocks D in As each horizontal course of tile B is laid up and interlocked with the permanent back portion of the wall, retaining devices 6 are slipped into the pockets 5 above the shanks 1, so as to eliminate the possibility of any o f the blocks B accidentally moving out `of lnterlocking engagement with the back portion A of the wall. If one of the tile B becomes defectivel it is only'l necessary to knock out the' tile B above same, then remove the retaining device 6 from the pocket 5 in the portion A of the wall, and thereafter move the defective tile B upwardly so as to disengage the shank of same'from the art in the back portion of the wall with which it is interlocked and also breakthe portions at the side edges of said 'defective tile which interlock with'the tile between which .itis positioned. A perfect tile` B can then be substituted for the defective tile and interlocked with the back portion A of the wall, and thereafter a perfect tile B can be arranged in operative position above the new tile B that was inserted.- Due to the fact that the tile B and B are interlocked with eachother by co-operating ribs and grooveson the edges of said tile, it is necessary to remove said ribs from replacement tilethat are inserted in the front portion of the wall to repair the same.
The air inlet tile C, previously referred to, can be arranged at any point in the wall where it is desired to admit heated air to the furnace chamber, and the permanent portion A of the wall can either be provided with llues 8, as shown in Figures 5 and 6, fromwhich ducts lead to the air circulating passageway between the permanent andrenewable portions of the wall, or. the permanent portion of the wall can be provided with numerous air inlets 9, as shown in Figure 4, through which air enters directly to the air circulating passageway between the' peiilnanent and renewable portions of the wa In Figures 7 and 8 of the drawings I have illustrated another form ofr' my invention,
wherein the renewable front portion of the wall is -made up of a plurality of tileB,
each of which is provided on its rear side with a. shank or rearwardly-projecting device 100 that is equipped with an angularlydisposed flange or head piece 1003, and the permanent back portion A of the wall is provided with horizontally-disposed slots `with the back portion of the wall, as above described, one vertical row of key tile B11 are incorporated inthe renewable front yportion of the wall So as to complete the face of the wall and prevent lateral movement of they tile B10 in a direction to t disengage the flanged head pieces on theishanks of same from the horizontal slots provided for same in the back portion of the wall. In such a wall the elements B10 that constitute the face of the wall which is subjected to the greatest heat are supported from thepermanent back portion A of the wall in the same way as in the form of my invention illustrated in Figures 1 to 6; they are held spaced away from the back portion ofthe wall so as topermit air'to be circulated over the rear Side of the renewable portion of the wall and they can be easil disconnected 'from the rear portion A of t e wall when they become defective and easily replaced perfect tiIeLthereby enabling the face of t e wall to be repaired without disturbing the back portion of the wall. v
In the form of my invention shown in Figure 9 the tile B2u that form the renewable front portion of the wall .are each provided .with an integral shank or rearwardly-projecting device4 .110 that projects -into a hole provided for Same in the permanent back portion A2 of the wall, said shank being provided in its top side with a notch 111 that is adapted to receive a retaining element 112 in the permanent portion A2 o the wall that can be inserted through a hole 113 arranged above the hole which receives the shank 110. In erecting such a wall the tile B20 are laid t up in horizontal courses, and after one horizontal course has been completed, the tile constituting same are locked inposition by means of the retaining elements 112 before the next horizontal course of tile is laid up.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
