BOILER rURNAcELy Application led February 5, 1926, Serial No. 86,163, and-in Great Britain July 8, 1925.
My present invention relates to furnaces particularly adapted foruse with steam boilers, the walls of which furnaces .are provided with devices by which they may be 5 cooled and maintained. My invention will be best understood from the following description and the annexed drawing in which Fig.' 1 is a rear elevation of a known form of steam boiler and furnace to which my invention has been applied, portions of the' figure being broken away for purpose of illustration; Figf2 is an .enlarged section on the line 2-2 of Fig. 1, and Fig. B is a view similar to Fig. 2 but showing a'moditication.
.Like reference characters indicate like p l *parts in the different views.
The steam boiler which I have chosen for purpose of illustration, is of the water tube.
isa row of cooling tubes 1.2, these tubes on .two opposite sides of the furnace being connected at their upper ends to a header 13 and at their lower ends t0 a header 14. The
lower headers 14 are connected through pipes 15 to the water space ofthe drum 10 and .the upper headers 13 are connected 4through pipes 16 to the steam space of the drum 10, or at least at a point higher than the connection of the pipe 16 to the drum 10.
In the two remaining sides walls, in the illustrative form, there is an upper header 17 and a lower header 18, the latter being connected at each end to one o f Ithe pipes 15 and the upper. header being connected by the pipe 19 to the drum 10. rlhe several headers are I'Jrcferably positioned outside of the furnace wall and the tubes 12 have their ends bent to extend through the wall into the respective headers. The particular means for supplying a cooling medium to 'the tubes. 12 which I have just described is no part of my present invention and fui'- ther description thereof will be unnecessary Ato those s'lilled'in the art.
Each of the walls is madefup of tile 20 described, the tile 20 are held in n which, in the illustrativeembodiment, are` oftubes 12, as best shown in Fig. 2, with .the joint between adjacent rows `of tile substantially opposite the tubes 12. r'Ihe side y edges of the tile 20. are recessed, so. that when t'he two rows-of `tile are lin position, as shown in Fig. 2, there will be a relatively large space formed aroundl the 'pipe 12 with ths space closed 'toward the front or furnaceside of lthe tile and opened at the outer side, the recess preferably being made narrower on its open side than the 'diameter of the tube 12. The wall preferably is laid' up without bond, and it will be noted by an inspection of F1g. 2 thatthe wall'maymove 1n `several directions independently of the .tubes 12 and, at the same time,l no tile 20 canybe removed fromthe wall without spreading a pair of 'tubes 12 for that purpose. f
l lVhen the walls arevdivergent, as shown 1n Fig. 1, the tile 20 will rest .against the tubes 12 so as to form a point contact there-l with, as shown in'Fig. 2, .and this will as-A sist in holding the wall in desired positionl while, at the same time, leaving it free for expansion and the' like. i Outside of the wallformed of the tile 2O is a casing 21 whichmay'be of the usual type or may be made-up of another row of refractory, .as desired. 22 between the-casing 21 andthe outer faces of the tile 20 forms an air circulation space B li- The space through which, in the. illustrative embodi- It will be seen that with'the arrangement described, not only is the wall cooled by the` presence of the tubes 1 2 through which water is, circulatlng, but is also cooled by the air whih is drawn through the spaces around the tubes 12, which spaces, in the form illustrated, are extended toward the inner or furnace face of the tile 2O to a point beyond the center of the tile. By the arrangement place by` the cooling tubes 12 and, at the same time, by
reason of the recesses or spaces around the tubes 12, the coolingair is brought close to the furnace side of the tile, so that the tile 20 may be maintained throughout at a closer approximation to uniform temperature than would otherwise be possible.
In Fig. 3, I have shownla slight modification of the wall in which the tile 2()CL have their edges shaped so as to provide substantially circular recesses, each "substantially concentric with a tube 12 and furthermore Fig. 3 shows the position of the parts where the wall is vertical and the tiles 20 therefore have no Vdefinite tendency to more against the tubes '12.
'1. In a furnace, a.row ot' tubes, connections to supply a cooling- `medium thereto, tile between each pair of adjacent tubes in the row, with the tubes betweenthe inner and-outer faces of the tile and with spaces in the tile through which the tubes extend, said spaces being closed as to the inner face ofthe tile and open as to the outer face, and
A anv outer wall spaced from said tile to form a cooling air passage therebetween.
2. In a furnace, a row of tubes, connections to supply a cooling medium thereto, tile between cach pair 4of adjacent tubes in the row, with the tubes between theinner and outer faces of the tile and with spaces in the tile through ewhich the tubes extend, said spacesA being closed as to the inner face ofthe tile and -open as to thevouter face,- an outer wall 'spaced Afrom said tile to form a cooling air passage therebetween.v and ineans tocirculate cooling air through said passage and through said spaces in the tile.
3. In a furnace, a row oftubes, connections to supply a cooling medium thereto, tile between each pair of adjacent tubes in the row, with the tubes between the inner and outer faces of the tile and with spaces in the tile through which the tubes extend, said spaces being closed as to the inner face of the tile and open as tothe outer face,
and an outer wall spaced from said tile to form a -cooling a'ir passage therebetween,
`said spaces in the tile extending'into the tile for more than half the thickness thereof.
4. In a furnace, a row of vertically disposed tubes incllned outwardly, connections to supply a cooling medium thereto, tile between each pair of adjacent tubes in ,the row. with the tubes between the inner and outer faces of the tile and with spaces in the tile through which the tubes extend, said spaces being closed as to the inner face of the tile and open as to the'outer face, said tile resting against said' tubes, and an outer wall.
spaced from said tile to form a cooling air passage therebetween.
5. In a furnace, a row of vertically disposed tubes, connections to supply a cooling medium thereto, a vertical row of tile between each adjacent pair of tubes, with recesses in their sides to forni, with the recesses in the adjacent -rows of tile, spaces surrounding the tubes, and with said spaces closed as to the inner faces of the tileV and open as to the outer. faces of the tile, and means to circulate air through said spaces 'and around said tubes.
6. In a furnace, a row of vertically disposed tubes, connections to supply a cooling medium thereto, al vertical row of tile between each adjacent pair of tubes. with rcccssesV in their sides to form, with the re- Acessesin the adjacent rows of tile` spaces surrounding' the tubes, and with said spaces closed as to the inner faces of the tile and open as tothe outer faces of the tile, and means to circulate air through said spaces and around said tubes. the width of the open ends of said spaces being less than the diameter of the tubes.
7. In a furnace, arrow of vertically dis posed tubes, connections to supply a cooling' `est the inner face of the tile.
