6 Claims.
Our invention relates to furnace wall construction and more especially to a segmentally supported wall where the fire brick units are supported both by steel frame work and the units themselves when assembled in a composite wall structure; and are held in place both by the interlockingfeature of the individual units and the steel frame work.
One object of our invention is to provide a steel frame work employing buck stays in a vertical position upon which are secured or attached in a horizontal position a metal bracket or clip upon which is secured or attached in a horizontal position angle irons which tend to hold the fire brick 15 units in proper position.
Another object of our invention is to provide a furnace wall in which all of the fire brick units are interlocking. y
A still further object of our invention is to provide a furnace wall in which both horizontal and vertical joints between the fire brick units are broken or interrupted which prevents the infiltration of cold air and escape of heat and products of combustion.
A still further object of our invention is to provide for an inward or outward adjustment of the fire brick units and also to provide means for longitudinal adjustment and for expansion through heat. v
3 A still further object of our invention is to provide a unit for a segmentally supported wall in which the main fire brick units. can be removed and replaced from the outside, as well as from the inside, of the furnace, which provides for a 35 quick repairing method.
A still further object of our invention is to provide a furnace wall wherein the fire brick units constituting the wall can be placed at varying distances from the main buck stay or supporting 40 members by use of different size clips or brackets.
The furnace wall comprises refractory bricks,
buck stays, brackets and angle-iron shelves I'I and preferably an enclosing sheeting I9. The
construction of our furnace wall will be clearly 5 understood from the following description taken with the accompanying drawings in which:
Figure l is a somewhat diagrammatic crosssection of a furnace boiler.
Figure 2, an isometric view of a portion of the 50 furnace wall.
Figure 3, a vertical section of furnace wall. Figure 4, a cross-section of the furnace wall on line 4-4 of Fig. 3. v
Figure 5, a cross-section of the furnace wall on 55 line 5-5 Of Fig. 3-
Figures 6, 7 and 8 are isometric views of fire brick units.
Figure 9 is a similar view of a steel bracket.
Figure 10 is a similar view of a steel angle.
Figure 11 is an isometric view of the furnace 5 wall showing alternate use of fire brick units.
Figure 12 is a cross section of the furnace wall on the line l2-l2 of Fig. 11 showing alternate use of fire brick units.
Figures 13 and 14- show another form of fire 10 brick units.
Figure 15 shows another form of steel bracket, and
Figure 16 is an enlarged cross-section of a detail. 15
In the construction shown in Fig. 2, the buck stays II have brackets l2 secured thereto at intervals by bolts l5. Brackets l2 have slots H in the horizontal portion for a purpose to be hereinafter described. By using brackets as I3 20 shown in Fig. 15, with very extended horizontal portions, the space between the buck stays and the bricks may be increased. Angle irons I! of which the horizontal portions rest upon, and are secured to said horizontal portion of the bracket, extend from one buck stay to another forming a continuous shelf and holding means for the re-' fractory units.
The horizontal or shelf portions of the angle 4 irons l1 have near their ends longitudinal slots I8 with countersunk edges, as shown, which slots' when the angle irons are in place on the brackets extend across the before mentioned slots in the brackets. Bolts l6 having nuts Ilia pass through said slots, thus adjustably securing the angle irons I! to the brackets l2. The slots l8 and M in shelf l1 and bracket l2 render adjustment possible and provide for expansion and contraction. The vertical portions of the angle irons extend when the refractory bricks are in 40 place in front of offsets on said bricks as will hereinafter appear. The above forms the essential metal portions of the furnace wall but it is customary to surround the furnace with a sheet metal or asbestos casing l9 bolted as at 20 to the buck stays and thus provide a space for an insulating body of air surrounding the furnace.
In the furnace wall as shown in Figs. 2, 3, 4 and 5 alternate horizontal rows are formed of 50 bricks of different shape. The bricks 23 of one set of alternate horizontal rows are of like shape, see Fig. 8.
l The bricks of the other set of horizontal rows are .made in two shapes 2|, 22 which alternate 5 5,,
. Figures 6 and 7.
' ditional security against leakage of hot gases to' Brick 2| shown in Fig. 6 has a downwardly extending offset 42 on its lower surface. This provides a lower surface to fit a corresponding upper surface on the brick 23 to be described. The outer portion 39 of brick 2| is offset sharply with respect to the front, extending further on each side as at 45, 46, 41, and beyond the upper surface as at 38 and stops short of the bottom surface as at 40.
Brick 22, which alternates in the same horizontal row in the finished structure with brick 2|, has a bottom surface similar to that of brick 2| but the outer portion of brick 22 is offset inwardly on the sides as at 33, 34, 31. The depth of the lateral offsets of bricks 2| and 22 are equal so that when laid side by side the lateral faces of both inner and outer portions of the brick may contact. The outer portion. of brick 22 has an upward projection 21 equal in height and width, though not in length to the upward projection 48 of brick 2|.
Brick 23 is preferably made equal in length to two of brick 2| and 22 and is a right angled parallelopiped except that the upper surface is stepped as shown at 26, Fig. 8, to correspond with the stepped lower surface of bricks 2|, and its width is less than the width of the upper surface of the inner portion of bricks 2|, 22.
The metal work being erected the bricks may be laidin place from the outside. The outer portions of bricks 2| and 22 resting on shelf I! and the upper projection fitting against the vertical flange of said shelf and supported in its position thereby. The inner portion rests upon the row of brick below.
When one row of bricks 2|, 22 has beenlaid the next row is laid of brick 23, with the vertical contacts of the rows staggered; the outer face of brick 23 fits against the downwardly extending flange of shelf l1 and the shoulder on the upper surface of brick 23 fits against the offset in the lower surface of the inner portion of bricks 2| and 22. I
In a modification of the furnace wall shown in Figs. 11 and 12 the structure is the same throughout except that the filling brick above described is replaced by bricks 5|, and 52 shown in Figs. 13 and 14.
These bricks are interfitting, one having a longer inner portion and a shorter outer portion while the other has a longer outer and a shorter inner portion. Both have the stepped surface as in Fig. 8. This alternate form of filling brick gives, by breaking the joint, an adthe metal work.
Having thus described our invention as required by the statutes, what we claim is:
-1. A furnacev wall structure comprising the combination of upright buck stays, angle brackv brackets, horizontal rows of bricks, the outer portions of which rest onthe angle irons below and the upper ends of said rear portions extend behind the vertical flanges of said angle iron shelves and alternate horizontal rows of filling bricks between said first named rows contacting the inner portions thereof and extending outwardly to the vertical flanges of said angle iron shelves.
2. A furnace wall structure comprising the combination of upright buck stays, angle brackets secured to said buck stays and angle iron shelves adapted to support a section of said wall, means adjustable both longitudinally of said wall and perpendicular to said wall, for receiving said shelves, on said brackets with the vertical flanges of said angle irons extending-below said brackets, horizontal rows of bricks, the outer portions of which rest on the angle irons below and the upper ends of said rear portions extend behind the vertical flanges of said angle iron shelves and. alternate horizontal rows of filling bricks between said first named rows contacting the inner por-' vertical flanges of said angle iron shelves, in,
which the first said horizontal rows consist of alternating bricks of interfitting shapes, one set having its outer portion offset beyond the lateral and upper surface of the inner portion and its lower surface offset above the lower surface of the inner portion while the outer portions of the other set of alternating bricks is offset in the same way at the upper and the lower surfaces but laterally is inset, and the lower surface of the inner portion .of both sets is stepped.
3. A furnace wall structure as claimed in claim 2 in which the first said horizontal rows consist of alternating bricks of interfitting shapes, one set having its outer portion offset beyond the lateral and upper surface'of the inner portion.
and its lower surface offset above the lower surface of the inner portion while the outer portions of the other set of alternating bricks is offset in the same way at the upper and the lower surfaces but laterally is inset, and thelowe'r surface of the inner portion of both sets is stepped, and the filling brick have a stepped upper surface to correspond to the stepped lower surface of the inner portion of the first said horizontal rows whereby all joints are broken, leakage of hot gases to the metal work is prevented, and the bricks may be removed from the exterior of the furnace. I
4. A furnace wall structure as claimed in claim 2 in which the first said horizontal rows consist of alternating bricks of interfitting shapes,
one set having its outer portion offset beyond the face of the inner portion while the outer portions of the other set of alternating bricks is offset in the same way at the upper and the lower surfaces but laterally is inset, and the lower surface of the inner portion of both sets is stepped, and the horizontal rows of filling bricks each consists of alternate interfitting bricks, one set having the inner portion longer than and extending above the outer portion while the other set has the inner portion longer than the outer, the vertical contacting surfaces of the bricks of one horizontal row being offset from the vertical faces of the bricks in the horizontal rows above and below it whereby all joints are broken and the leakage of hot gases to the metal work is prevented.
5. A furnace wall-structure as claimed in claim 2 in which the first said horizontal rows consist of alternating bricks of interfitting shapes, one set having its outer portion offset beyond the lateral and upper surface of the inner portion and its lower surface offset above the lower surface of the inner portion while the outer portions of the other set of alternating bricks, is ofiset in the same way at the upper and the lower surfaces but laterally is inset, and the lower surface of the inner portion of both sets is stepped, and in which said outer portion is of less width than the space between the vertical flange of the horizontal angle iron shelf and the inner surface of the buck stay whereby an air space exists between the outer face of the brick and the inner face of the buckstay.
6. A furnace wall structure as claimed in claim 2, in which said angle brackets have transverse slots in their horizontal flanges and said angle iron shelves have longitudinal slots in their horizontal flanges, said slots registering with each other and bolts passing through said slots to ad.- justably secure said shelves to said brackets, whereby on expansion or contraction said shelves and brackets may move relatively to each other both in a direction transverse to the wall and a direction longitudinal oi the wall.
