DECEASED; ASSIGNOBS T0 METROPOLITAN rEN'GIN' EERING' COMPANY, .A CORPORA-I The invention aims lto provide improved wall structure for. boiler furnaces, particularly for furnaces operating at very lpilgh temy eratures such as those fired with powdered coal, oil or gas.
i -The accompanying drawings illustrateemn) bodiments of the invention. Fig. 1 is a perspective 'front 'tionofawall\; i J j m Fig. 2 is a horizontal section pf the same;v
Figs. 3 to 7 inclusive are similar views il- Ylustrating modifications. i l.
Referring rst'to Figs. 1 and 2, the princi- 'pal part. of the structure is a wall 1 of brick workor similar refractory insulating material or materials, which ma be in one or'more layers. 0n the inner fa of this refractory material it is faced with metal plates 2 which .may be vof sheet steel preferably/of special compositions highly resistant to ox'idatlon at high temperatures, or coated with such compositions.
-v'iew of a sec--v I i The plates may be vunited to .the refractory backing by anchors imbedded in the latter, or in any other usualorsuitable way. Channels .3 open toward the inner,face, of the wall and rare' arranged at intervals corresponding to -the width okf the plates, and the latter are prow vided with backwardly bent ignges 4 iitting in said channels. 'A slight space'isleft be' tween the anges in each 'channel when the wall is, erected,permittingy lateral expansion of the plate's' when heat isapplied' to vthe furnace. Y.
ln front of the structure thus described, and which may be vreferred to as a whgle as, a refractory wall', isa-row ofwater tubes 5 con-v .nected into the boiler circulation and prefer- 'l ably in upright position so s to facilitate circulation .ata high rate of speed'.
which is-'radiated directly a 'nst'the tubes 5. and, in the spaces between e tu agalnst themetal'fa'ced refractory wall.; The tubes with the water in them createa comparatively 'cool zone adjacent to. the metal plates and n protect' them sothat they are durable even, under l extreme conditions. The high temperature will produce a certain expansion of nv the pini-,es relative. t0 'the insulating inganni,

welded'to a tube.` The fuel produces anintense heat which will be taken up inthe iian'ged er1-)an I ysion joints. The plates may be in turn coated Witha mineral coating aid maybe specially protected line with the spaces between the 5 tubes, as set out in detail in'my previous appli- 55 entibn'Nos1773afi1ed March 23, 1927.
In a previous British patentR of mine, No.
227,156, I have shown a .somewhat similar wall faced jwith plates and tubes, arranged alternately 'along the width of the wall. In '60 -'the present arrangement the metal facing passes continuously back of the' tubes. The tubes may be fastened to the metal facing of the wall or-maybe separate from such facing.
In Fig. 2l they are shown united to the plates e5 2 by welding metal 6 deposited at the joint. f According to Fig. 3 the tubes 5 are spaced slightlyaway Afrom the metal face. Also this'figure the facin'g plates 2 are provided at fitting in recesses in the refractory material their adjacent edges with inclined flanges 7, 71x
and adapted to yield by bending when theW I plates ex and laterally.
Accordin bends 9r fitting in recesses in the refractory material and adapted to yield to permit the "w sections to expand toward one another. A'
w g to Fig. 4 the vmetal facing is i y made in sections 8 with U-shaped or similar 75 'm'ple, at an expansion bend as indicated at Fig. 5 illistrates an arran ement in 85 .the tubes 5 are spaced away rom the'sections or plates 2 but connected to them by means of a. web 11. For example the web 11 may be a rib rolledl integrallywith `afplate 2 and Fig. 6 illustratesi construction like that of i. Fig. 4 except that the tubes' 5 are located' 1 against themetal fastened thereto.
' According to Fig. 7 the tube 5 has welded 95 `on to it studs 12 which pss'through o en- L- ings-inA e metal-facing 8 and are rive `by plate.

facing of the wall but not 'an enlarged head 13 to fasten the tube lto the l I l lEllach of the several arrangements andlo- Ay 'cations of the tubes shown and described herein may be used with any one of the lar'- rangements of the metal wall facing. .The tubes in each case `except Fig. '3 are illus- 5 trated' as located at the center'of each plate or corresponding section of the metal facing, with one tube for each section. Where the tubes are fastened to the metal Vfacing this y, is important in permitting expansion of the 10 sections' with the least -lateralstrain on the v tubes: i And in anyjrase .it is advantageous to y havethe tubes arranged uniformly with-respecttoeach section. Where they are not fastened to thermetal facing, theymay be 15 ,located-in' front of the'joints so as to aii'ord special protection to thelatter, as illustrated for example in Fig. 3; 'orthey may be located between the joints as in Fig. 6.
Various otherl modications may be made go without departing from the invention as .de-
ned in the following claims. 1
