SPIRAL RIBBON GAS `BURER Filed oct.` 19, 1966 INVENTOR AT TO RN EYS.
United States Patent Ofi ice 3,438,719 Patented Apr. l5, 1969 U-S. Cl. 431-286 6 Claims ABSTRACT OF THE DISCLOSURE A burner assembly for use in a tire tube boiler including at least one pipe adapted to receive a combustible mixture therein, with a plurality of spaced generally circular openings in the pipe each having a cylindrical wall around the opening with a burner disc secured within each wall. Each disc is defined by a single length of spirally wound ribbon burner element, with spaced corrugations in each element cooperating with non-corrugated portions to form outlet openings of small cross sectional area. Diametrically extending -pins positively retain each disc within its respective wall, and also hold adjacent convolutions of each disc against movement relative to one another.
This invention relates in general to an improved burner construction, and more particularly to a burner construction for use in a fire tube boiler.
In the past, it has been well known to provide a boiler construction wherein a plurality of fire tubes extend longitudinally through a heat exchange chamber containing water or the like. It has also been known to provide individual burners for each of the tire tubes adjacent one end thereof for igniting a gas-air mixture. While such boiler constructions have in general functioned satisfac torily, heretofore, it has not been possible to modulate the tiring rate -of the boiler; and consequently these boilers have strictly `been on-otf units. Modulation of fire tube boilers has heretofore not been possible, because of a flashback phenomenon, that is, a lighting of the combustible mixture in the burner manifolds and burner pipes, when the burner is turned down from a maximum rating to an intermediate or low rating. The flashback phenomenon occurs because burners that have been used in the past eject the combustible mixture through a relatively large hole, for example, 11/2 to 1" diameter; and with such a hole size, the velocity of mixture therethrough at intermediate or low firing rates is sufficiently slow that flashback occurs in the mixture feeding manifolds. Accordingly, the general purpose of the present invention is to provide an improved burner construction for a fire tube boiler which will eliminate the flashback phenomenon during intermediate and low firing rates, so that the tiring rate of the boiler can be generally universally modulated.
An object of the invention is to provide an improved burner c-onstruction for a fire tube boiler which will provide uniformity of firing throughout the boiler, so that there will be uniform heat transfer to the substance being heated.
Another object of the invention is to provide a burner for a fire tube boiler having a configuration such that localized flames of high capacity are provided, which can be spaced as desired.
A further object of the invention is to provide an improved burner header construction which enables individual burners to light adjacent burners without the flame impinging upon the tube sheet ligaments between the burners.
Still another object of the invention is to provide a burner construction as described in the preceding paragraph with ame deflector means arranged to space the burners a desired distance from the tube sheet, thereby giving uniform spacing between each of the burners and the ends of the fire tubes.
A still further object of the invention is to arrange the flame deflector means of a burner as described above, so that it will be cooled by the water within the boiler via the engagement of the flame deflector means with the tube sheet.
Still another object of the invention is to provide a plurality of rows of burner headers` arranged such that a single pilot burner at one end of the rows can ignite each of the burners.
These and other objects of the invention will hereinafter become `more fully apparent from the following descrip tion taken in connection With the annexed drawing wherein:
FIG. l is a perspective view of a boiler having thel burner means of the present invention incorporated therein, with certain portions of the boiler being broken away for clarity of illustration;
FIG. 2 is a broken, front view of a burner header;
FIG. 3 is an enlarged cross sectional view taken generally along line 3 3 of FIG. 2;
FIG. 4 is an enlarged cross sectional view taken generally along line 4 4 of FIG. 2;
FIG. 5 is an enlarged perspective view of a ribbon burner element; and
FIG. 6 is a perspective view of the means for securing one end of the ribbon burner element.
While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will herein be described in detail a preferred embodiment of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the embodiment illustrated. The scope of the invention will be pointed out in the appended claims.
Referring now to the drawing, wherein like reference characters designate like or corresponding parts throughout the several views, a fire tube boiler is designated in its entirety by reference numeral 10 in FIG. l, and includes a generally cylindrical shell 11 defining a heat exchange chamber 12 therewithin. A plurality of horizontally aligned rows of tubes 13, which are preferably dimpled, extend longitudinally from end to end of chamber 12, and the ends of tubes 13 are held Within tube sheets 14 and 15 at opposite ends of the shell 11. A burner assembly 16 is provided at one end of boiler 10 outwardly of tube sheet 15, and burner assembly 16 is preferably housed within a cover box 17 that may be hingedly connected to the shell 11 and sealed thereto by a gasket when closed, so that the burner assembly is completely en-closed. Burner assembly 16 includes a plurality of horizontally extending burner headers 18, each of which is provided with a plurality of horizontally `spaced burners for providing a flame Within each of the tubes 13. The spent combustion gases pass from right to left, as viewed in FIG. 1, through the tubes 13 in a single pass through the heat exchange chamber 12, and the exhaust gas passes outwardly of the boiler 10 from a stack 19 communicating with an exhaust chamber defined between tube sheet 14 and an inclined baffle plate 20.
Air for combustion is drawn inwardly of the boiler shell 11 by a fan 21 that is driven by a motor M, and the air is forced through primary conduits 22 and 23 and mixed with gas from supply line 25 in Venturi assemblies 26 at opposite sides of the boiler. The gas-air mixture is conveyed through supply manifolds 27 and 28 at opposite sides of the boiler into the headers 18, and secondary air is forced through a conduit 24 by fan 21 into the plenum chamber defined behind the burner assembly 16 and the cover 17. Supports S extend upwardly from pipes 22, 23 and 27 to the boiler shell 11; so that the pipes serve as supports for the boiler shell, as well as to convey the gas-air mixture to the burner assembly. Linkage operated damper means D is provided in the air lines, and as the amount of air is increased, the amount of gas drawn in increases proportionately to give a proper combustible mixture in the burner assembly 16. While gasair supplies are illustrated in FIG. 1 at opposite sides of the burner assembly 16, it will be apparent from the following description that the mixture may be provided at only one side of the assembly, if desired.
The header construction 18 illustrated in detail in FIGS. 2-4 is usable in a structure wherein only a single supply manifold 28 is provided, in that the header 18 is provided with an elbow connector 32 at one end for connection with the manifold 28, and a plate 31 that closes the opposite end of the header. However, in the arrangement such as that illustrated in FIG. l, wherein manifolds 28 are provided at opposite ends of the burner assembly 16, the headers 18 would be provided with elbow connectors 32 at opposite ends thereof connected with respective manifolds 28. As can be seen in FIGS. 3 and 4, headers 18 are generally cylindrical tubes, and spaced circular openings 33 are provided in one side thereof, with an upright wall 34 extending substantially peripherally around each opening 33. Elongate slots 35 connect adjacent openings 33, and upstanding walls 36 are provided at opposite sides of each slot 35. Headers 18 are preferably formed by machining an elongate continuous slot in the side wall of the header, and then drawing inserts upwardly from within the header to form the circular openings and the upstanding walls therearound.
When the discs 37, inserts 46, and flame deflectors have been assembled to each header 18, the headers are then assembled to the manifolds 28 to form the burner assembly 16. The burner assembly 16 is then positioned adjacent the tube sheet 15, and as is evident from FIG. 4, the outer surfaces 54 of fiame defiectors 50 abut against the outer surface of the tube sheet 15. This enables the burner discs 37 to be spaced an appropriate amount from the ends of tubes 13, as is evident from FIG. 3, it being understood that each burner disc 37 is positioned in longitudinal alignment with one tube 13. A single, vertically aligned pilot sandwich burner (not shown) may be positioned forwardly of the outermost disc 37 in each header 18 to impinge upon the gasair mixture issuing therefrom to ignite the same. The liame issuing from each burner disc 37 will be directed longitudinally into its associated tube 13, and the gasair mixture supporting the fiame will pass outwardly of the disc 37 through the small openings 43 at high velocity, so as to obviate the possibility of flashback in header 18 or manifold 28. The gas-air mixture will also pass through the small openings formed between the sandwiched layers of the inserts 46, and the gas issuing therefrom will be lighted from an adjacent burner disc 37, so that each of the burner discs in a particular header is ignited from an adjacent insert 46. Flame deflectors 50 are formed of a suitable heat resistant material, such as stainless steel, and effectively prevent the fiame issuing from the inserts 46 from impinging upon the tube sheet 15, while still allowing ignition from one disc 37 to an adjacent disc 37. Because of the relatively large, facial engagement between flame deflector 50 and tube sheet 15, the water or other substance within heat exchange chamber 12 will have a substantial cooling effect on the flame deflectors.
In an exemplary embodiment of the invention, wherein the fire from disc 37 passes into a 21/2" boiler tube, the capacity of each of the burner discs 37 is 125,000 B.t.u. per hour with a mixture pressure of 4" W.C. In a boiler having one hundred boiler tubes 13, the total input rate to the boiler is 12,500,000 B.t.u. per hour, and the uniformity of firing with such a boiler can be readily visualized. Thus, it is submitted that the unique burner construction of the present invention fully achieves each of the objects of the invention.
