Howthe foregoing, together with' such other objects as may hereinafter appear, yor
are incident to my invention, are realized, is illustrated in the accompanylng drawings,
, J5 wherein- Fig. 1 is a vertical section through an installation embodying myimproveme'nts, and Figs. 2 and r3 'are enlarged fragmentary views illustrating means for supporting cer- Referrmg now to Fig.V 1, the reference character A denotes a boiler such, for example, of the cross ldrum type; the reference character B denotes the setting for such boiler, such setting being carried on structural work 7; the reference character C ,denotes'the bottom of the furnace, said bottom being spaced well below the boiler setting; `and the reference character D denotes the structure which bridges the gap between the boiler setting B and the bottom C to'complete the combustion space. The bottom C is supported on the structural work 8.
The structure D comprises the row of rela-- tively closely spaced upright tubes 9 defining the rear .of the combustion chamber of the furnace; the two rows ofV relatively closely spaced'V upright tubes 10 defining the sides of the combustion chamber and the row of relatively 'closely spaced upright tubes 11 deaportion of the front of the combustion cham er. The tubes of the rows of upright tubes are each 12 at opposite sides, the tubes and fins cooperating toform `a substantially continuous metallic wall. The upper and lower ends ofthe tubes .ofthe rows are bent to extend outwardly at the top through the 0 setting B and outwardly at the bottom 'which carries thesetting,

through the-bottom portion C. The upper and lower ends of these tubesconnect into headers as shown, .and these headers are connected with the boiler for circulation purposes. Where the upper ends 'of thevtubes extend outwardly through the setting B, sand Joints 13Nare provided, and, similarly, sand joints'14 are provided where the lower ends of the tubes extend outwardly. The .rows of tubes are suspended from the structural work pear, this form of support, in conjunction with the sand joints, permitting the tubes contract. It will be seen from the foregoing that, generally considered, the boiler and its setting and the bottom portion of the furnace are independently supported and can be independently erected, and that thereafter the intervening structure may be readily installed. ThisY inte largely composed of tubes, requires no hea wall structure, such as wouldA otherwise be required, it being necessary only to sheath the rows of tubes as with a sheathing l5 Euro1-Fics as will further aprvening structure being which can bereadily carried, if desired, on
will be obvious that where all.of the load'is carried on a single and heavy refractory structure mustL be provided. This I avoid'entirely. v
I f it is desired to provide some radiating surface to secure the ignition and proper combustion of the fuel, the bottom C may be carried up .at -one side, as indicated at C', and the burner -or posed to deliver the fuel tion space through such extensionC.
burners 16 may be disinto the combus- Ifvr desired, a screen E of relatively wide- 1y spaced tubes may be located above the ash pit 17 e Referring now to the means for suspending the rows of upright tubes, it w11l be seen that the header 11 with which the upper ends of the tubes y11 are connected'is supported on saddles, 18 supported by the structural work 7 as indicated. The tubes 9 have channel-like members 19 secured to their outer face, as by welding, and these members are adapted to receivethe lower 19 ends of the su ension rods 20 carried from the clips 21 which are secured to the channel 22 which carries the curtain Wall portion 23. The channel 22 is supported from the structural work 7 by means of brackets 24 and 25, as indicated. The tubes 10 may be supported in a fashion similar to the tubes 9.
In combination, a boiler and its setting, structural work upon which said setting is carried, a refractory furnace bottom belowr and spaced from said setting, means for supporting said bottom, and a plurality of rows of relatively closely spaced upright tubes adapted to be suspended from said structural Work and between said setting and said bottom to form the side wall portions of the space and to cover said structural work, means for so sus ending the tubes engaging the outer face o the tubes, :and a sheathing l for the rows oftubes.
In testimony whereof I have hereunto signed my name.
