Claims.

This application is a substitute for my abandoned application for'Sectional furnace wall and tube packing, filed April 22, 1940, Serial No. 330,948. This invention relates to furnace walls and more particularly to that section or portion construction and organization of parts as hereinafter described and claimed; and in order that it may be fully understood, reference is to be had to the accompanying drawings, in which:

Figure 1 is a horizontal section through a furnace wall section embodying the invention, said section being taken on the line 1-1 of Figure 2.

Figure 2 is an elevational View of the inner face of the furnace wall as well as indicating fragmental vertical sections corresponding to the showing of Figure 1.

Figure 3 is a vertical transverse section taken through the wall on the line III-III of Figure 1.

In the said drawings, where like reference characters identify corresponding parts in all of the figures, the type of furnace illustrated, by way of example, is of the metallic sectionally supported wall type, in which I are a series of horizontally spaced vertical columns, and attached in vertically spaced relation to the inner faces of the columns, are longitudinally extending rows of supports 2 for tile or refractory, which may support rows of tile 3, or may support brackets 4, which, in turn, support the tile 3 as shown. Each horizontal belt or section of the furnace wall is completed by utilizing the tile 3 as supports 'for ordinary brick 3a.

At any suitable point intermediate the height of the columns I, depending upon the type of boiler, the columns may carry right-angle flanges 6 which may support shelf plates I inserted below a horizontal I-beam 8 located in a vertical plane outside the plane of the fire face of the wall. The vertical web of said beam may be reinforced by plates 80. welded to its opposite sides, the parts being formed with a plurality of spaced openings or perforations 9 of such size as to receive the water tubes ll) of a water wall construction of any type. Where the water tubes must'be free for vertical expansion, the openings 9 are vertically elongated as shown, and the tubes when cold, are installed atthe proper end of the openings or slots "9 to allow movement upon expansion. In one type of boiler construction, the horizontal beam 8 may carry a bracket H in which aheader '12 receiving the endsof the tubes I0, is mounted, for vertical movement on expansion of its tubes. After installation of the tubes the wall section may be completed in any suitable manner as by filling in the fire side with plastics, a sectionally supported belt of tile, an independently supported wall, or otherwise.

However, the preferred construction of this belt of the wall is, as follows: In order to provide a shelf or support for compressible packing [3 around thetubes H], the beam 8 has a lower flange I4 which constitutes a shelf'or support'for packing l3 around the tubes, and to further strengthen the beam, particularly if its constitutes a part of the lateral support of the furnace framework and carries the load'of the upper part thereof, said beam is preferably provided with a series of spaced F -shaped vertically extending reinforce members, the headsl5 of the T-members being spaced from and parallel to the beam web, providingpockts or spaces between which a portion of the packing is'stuffed and thereby more effectually holding the packing from moving laterallyaway from the beam. The stems I6 of the said T's, being welded to the beam web, b'ypreference, form a series of sections or compartments and thus sectionalize the packing so that local loosening will not be readily propagated longitudinally of the beam. If the construction is to be completed by a suspended wall section or belt, the T-heads l-5carry a horizontal tile support 2 on which suitable tile 8 may be suspended, or said supports may carry separate tile hangers 4, to which the tile I 8 may'be removably secured,

as shown.

From the ,above description and drawings it will be apparent that while I have described and illustrated a construction embodying the features -of advantage set forth as desirable, it is to be understood that I reserve the right to all changes within the spirit of the invention and without the ambit of the prior art.

I claim:

1. In a sectionally supported furnace wall construction, a perforated horizontal beam paralleling and outside the vertical plane of the combustion side of said wall, a tile-support projecting from the furnace side of the beam, water tubes extending into the furnace through the perforations in the beam, tile carried by said tile-support and providing openings accommodating the water tubes, and packing inserted between said tile and beam.

2. In a sectionally supported furnace wall construction, a horizontal beam paralleling and outside the plane of the combustion side of said wall and having a perforated vertical web and top and bottom horizontal flanges, a tile-support projecting from the furnace side of said beam, water tubes extending through the perforations in the beam, tile carried by the tile-support and providing openings accommodating said water tubes, and packing inserted between said tile and beam.

3. In a sectionally supported furnace wall construction, a horizontal beam paralleling and out-.v

side the plane of the combustion side of said wall and having a perforated vertical web and top and bottom horizontal flanges, a T-shaped reinforcing member extending vertically from flange to flange of said beam, the stem of said member being at right angles to the web and its cross head paralleling the web, a horizontal tile-support carried by said reinforcing member, water tubes extending through the perforations in the web of the beam, and tile carried by the tilesupport and providing openings accommodating said water tubes.

i. In a sectionally supported furnace wall construction, a perforated horizontal beam paralleling and outside the vertical plane of the combustion side of said wall and having a horizontal flange at its lower edge projecting toward the furnace, a tile-support carried by the beam and spaced above said flangawater tubes extending into the furnace through the perforations in the beam, tile carried by said tile-support and providing openings accommodating the water tubes, and packing around the tubes between the tile and beam and supported by said beam flange.

5. In a sectionally supported furnace wall construction, a horizontal beam paralleling and outside the vertical plane of the combustion side of said wall and having a perforated vertical web and top and bottom parallel flanges projecting toward the furnace, a reinforcing member paralleling the web and connecting the edges of the top and bottom flanges to form a pocket between the proximate faces of the member and web, water tubes extending into the furnace through the perforations in the beam, and packing around the tubes between the proximate faces of the member and web and supported by the bottom flange of the beam.

6. In a sectionally supported furnace wall construction, a horizontal beam paralleling and outside the vertical plane of the combustion side of said wall and having a perforated vertical web and top and bottom parallel flanges projecting toward the furnace, a reinforcing member paralleling the web and connecting the edges of the top and bottom flanges to form a pocket between the proximate faces of the member and web, water tubes extending into the furnace through the perforations in the beam, a tilesupport carried by said reinforcing member, tile carried by the tile-support and providing openings accommodating the water tubes, and packing around the tubes between the proximate faces of the member and web and supported by the bottom beam flange.
