J. VAN BRUNT FURNACE WALL SONSTRUCTION Filed July 25,- 1925 2 Sheets-Sher f//f/ U// Patented Dec, 6, 1932 UNITED sArEs i JOHN VAN BBUNT, OF FLUSHING, NEW YORK, AS'SIGNOR 'TO INTERNATIONAL COM- BUSTION ENGINEERING CORPORATION, A CORPORATION OF DELAWARE remmen WALL coNs'rnUo'rIoN Application :Bled July 25,
tions. One of the primary objects of my invention is to provide a simple form of wall conlsltruction, whether top bottom or vertical wa Another object of the invention is to dispense with the more or lesscomplicated and expensive brick wall construction', for furnaces of this character and to substitute therefor a very simple form of wall construction in which expansion and contraction are provided for.
Still another object of the invention is to provide a novel and improved form of water wall construction for furnaces.
How the foregoing, together with such other objects as may hereinafter appear, or are incident to my invention are realized, is illustrated in the accompanying drawings, wherein:
'Fig l is a vertical section thru an upright wall of a combustion chamber embodyingmy improvements lbig. 2 is a fragmentary front elevation ci the wall shown in lig. l; ylig. 3 is a section taken on the line 3-3 of lig. l;
Fig i is a similar cross section drawn on a larger scale to more clearly illustrate the parts, and l lli .f 5 is a side elevation of a supporting member. y
In the embodiment shown in the drawings the invention is applied to an upright wall, say, for example, the rear wall of the combustion chamber. This wall comprises a base section 'i and a curtain section 8., these two sections being composed of any suitable material, such, for example, as refractory bricks. The section 7 is carried on suitable foundation worlr and the curtain section 8 is carried cn the structural work 9. The gap -between these two sections is hlled by the .wall portion A. new to be described.
This wall-portion has :its inner face, that is the face thereof next the heme, formed of,
1925. Serial No. 45,974.
a plurality of tubes 10. These tubes prefer-I ably have longitudinally extending fins 11 arranged in substantial abutment as indicated in Fig. 4 so as to provide, for all practical purposes, a substantially uninterrupted face. The upper and lower ends of the tubes are bent so as to extend outside the wall for connection into the upper and lower headers l2 and 13 respectively, such headers in turn being suitably connected into the circulation ofthe boiler in any preferred manner. rlhe header 12 is supported from the structural -worlr'g in the manner illustrated and theheader 13 is yieldingly supported by the supporting mechanism indicated as a whole by the reference number lll, whereby the tubes are in effect suspended, expansion "and contraction taking place from the header l2, to which end' a sand or other yielding joint 15 is providedk where the tubes pass thru or over the base section 7 of the wall.
(Certain of the tubes are provided on what would be their outer faces with tabs or lugs 16 arranged at suitable intervals lengthwise of the tubes. The tabs are preferably welded to the tubes and secured to the tabs, as by bolts l?, are vertically extending plates ]l8. Metallic panels 19 extend between the plates 18, the panels being secured together and to lsuch plates by bolts 20 for example. Yllhese panels are spaced out from the tubes and the space between the outer faces of the tubes and the panels is filled with a lining 2l composed, for example, of per cent magnesia or similar material. Molded tiles 22, preferably of Sil-o-cel, or the like. till the gap between the lining 2l and the tubes and fins, these tilesbeing built up one upon the other. rll`he tiles and lining constitute an insulator to prevent radiation of heat to the exterior as much as possible.
'llhey also serve to protect the paneling. A" 4more refractory material is preferable for l the tiles as these are nearest the source of hottest temperature, but in this connection itis vto be understood that the absorption of heat by the tubes and -ns will serve to protect such tile, articularly in view of the fact that the circulation thru the tubes will be very rapid because of their vertical disposition.
It will be apparent from the foregoing that the whole wall A is a suspended o iie and can expand and contract vas a unit. -It willalso be seen that it is much more simple than the brick walls heretofore employed.
The structural work 9 may be' utilized to laterally brace the wall, as by the employ- -ment of a horizontally extending angle 23 adapted to bear against' the outer face of the wa The pointl where the upper ends of the tubes pass out is preferably packed with yielding material 24 if this is necessary. In any event a friable material is employed in order to permit replacement of tubes.
What I claim is: u
1. In a boiler having overhead water tubes heated by convection om the heating gases and having a furnace with a combustion chamber below said tubes, a side wall of said K furnace comprising a setof u right water tubes, said wall being supporte from above independently of said overhead tubes, and spring means supporting said wall at the bottom thereof and permitting expansion and contraction thereof.
2. In a boiler havin overhead water tubes heated by convection rom the heating gases and having a furnace with a combustion chamber below said tubes, a side wall of said furnace comprising a set of uiright water tubes, said wall being supporte from above vindependently of said overhead tubes, and having the lower ends of the tubes thereof passing through the furnace Structure to the exterior thereof, an expansion joint at the point of passage through said structure, and spring means outside the furnace for yieldingly supporting said lower ends of the tubes.
3. In a boiler havin overhead water tubes heated by convection from the heating gases and having a furnace with a combustion chamber below said tubes, a side wall of said furnace comprising a set of u right water tubes, said Wall being supported) from above independently of said overhead tubes, and having the lower ends of the tubes -thereof passing through the furnace structure to the exterior thereof, an exgansion joint at the point of passage throug said structure, a header exterior of the furnace into which the said lower ends of the tubes are connected, and spring means outside the furnace yieldingly supporting said header.
In testimony whereof, I have hereunto signed my name.
JOHN VAN BRUNT.
