JACOBUS, OF MONTCLAIR, NEW JERSEY, ASSIGNOR TO .THE BABCOCK & 'WILCOX COMPANY, BAYONNE, NEW JERSEY, A CORPORATION OF NEW JERSEY TUBE SUPPORTED FURNACE WALL I Application filed July 16,
This invention relates to a furnace wall in which water tubes may be installed to receive heat from the furnace, and also to aid in supporting the Wall. The invention will be understood from the following description in connection with the accompanying drawings, in which Fig. 1 is an elevation, partly in section, throughthe furnace; Fig. 2 is a view of the wall appearing at the right m of Fig. 1, as viewed from the inside of the furnace; Fig. 3 is a section on the'line 3-3 of Figs. 1 and 2; Fig. 4 is an enlar 'ed section showing one of the details of t e construction appearing in Fig. 3; Fig. 5 is a view 5 corresponding to Fig. 2, but showing another embodiment of the invention; Fig. 6 is a section on the line 6-6 of Fig. 5.
In the drawings, reference character 10 indicates a furnace that may be provided with a fuel burner, as indicated at 11. A boiler is shown mounted above the furnace having inclined tubes 12, the ends of which are connected to headers in the usual way, which are, in turn, connected to the steam and water drum 13. One or more pipes 14 lead from the steam and water drum 13 outside of the boiler setting to the header 15, from which a plurality of parallel tubes 16 extend upwardly within the furnace wall and then outwardly to a header 17, from which a tube 18- leads to a header 19, from which header tubes 20 lead to a distributor 21. Tubes 22 connect the distributor 21 to the steam and water drum 13.
of the steam and water drum 13 outsi e of the boiler setting to the superheater header 24, from which parallel tubes 25 extend u wardly within the wall, and the .upper en project outwardly and extend into the outlet header 26 of the superheater.
In the embodiment shown in Figs. 2, 3 and 4, a superheater tube 25 is installed in front of each water tube 16 on the side toward the furnace, and tile 31 as well as holding tile 31" that are preferably metallic are provided. The portions of the tile 31 between the tubes 16 are rounded to fit'the tubes, but the portions between the tubes 25 have parallel ends. The holding tile 31", which may be installed A steam pipe 23 leads from the steam s ace- 1926. Serial No. 122,803.
in courses in horizontal rows to alternate with a'series of courses of the tile 31, are rounded along the portions between the tubes 16 a suflicient amount to become anchored between the tubesand prevented from slipping out, while the portions between the tubes 25 are similarly rounded and extend beyond the center line of these tubes to hold them in position. The superheater tubes 25 are exposed to the radiant heat of the furnace, and the insulating material 33 contacts directly with the tubes 16. The tubes 16 are provided with rods or tie pieces 28, preferably welded to these tubes and extending outwardly from the furnace and passing through holes in thin metal plates 29, suitable nuts 30 being provided on the threaded outer ends of the tie pieces. The plates 29 in this modification also have edges turned back, as indicated at 29 (Fig; 4) and the tie rods 28 ass throu h the joints as indicated, thus holding t e plates securely in position, the lates bulging out as indicated, to accommo ate-the insulating material.
In the embodiment shown in Figs. 5 and 6, there are twice as many superheater tubes 25 as there are water tubes 16, and the su erheater tubes are exposed to the radiant heat of the furnace. In this modification, tile 31 have their ends rounded, as indicated,
to fitthe tubes 16 and 25. Holding tile 31,,
preferably made of metal, extend farther inwardly toward the furnace than the tile 31 and are rounded to fit .the tubes 16 and 25, leaving aspace in front of the tubes 25 so J that they will be exposed to the radiant heat of the furnace. Holding members 31 ma also be installed between the tubes 25 wit their ends rounded to fit these tubes, and these holding pieces may be made of metal and welded to the tubes 16. In this modification, the insulating between the tie members 28, and itsside toward the tubes is provided with arcuate portions to contact with the tubes 16, and also with the corresponding portions of the tile 31 and 31 v It will be observed that water from the steam and water drum-13 of the boiler enters the lower ends of the water tubes 16 and material 33 also bulges out passes upwardly and back into the drum. Also, steam from the steam. and water drum 13 enters the lower ends of-the superheater tubes and asses upwardly through the same. The tu s 16 and 25 aid in supporting the tile that constitutes the furnace wall, and may extend not only along the back sideof the furnace wall, as illustrated, but also around additional portions of the walls of the furnace.
Various modifications and changes may be made Without departing from the spirit or scope of this invention.
I claim:
1. In a furnace wall, a row of spaced water tubes, tile extending between said tubes and formin a wall having recesses opening towards the inner surface of the wall and receiving said tubes, and superheater tubes extending into said recesses between the water tubes-and said inner surface.
2. In a furnace wall, a row of spaced I water tubes, tile extending between said tubes and forming a wall having recesses opening towards the inner surface of the wall and receiving said tubes, superheater tubes extending into said recesses between the water tubes and said inner surface, tie rods secured to said water tubes and extending outwardly therefrom, plates held in position by said rods, and insulating material disposed between said plates and said tubes and tile.
3. In a furnace wall, a row of spaced tubes, tile extending between said tubes, a second row oftubes contacting with said tile, and
members welded to tubes in the first row and holding the tubes of the second row against the tile.
