Each end nipple includes a wall extending from the first end to the second end and including a bore extending through the first end to the second end. Each end nipple includes a threaded hole extending through the wall to the bore. The first end of the end nipple, the second end of the end nipple, and the wall of the end nipple are unitary. Each jet includes a threaded portion threadedly engaged with the threaded hole and a fuel combustion outlet spaced from the threaded portion. Each jet includes a barrel extending from the fuel combustion outlet toward the threaded portion. The barrel has a larger outer diameter than the threaded portion.
Description
- This application is a Patent Cooperation Treaty Application that claims priority to U.S. Provisional Patent Application No. 62/987,535, filed on Mar. 10, 2020, which is herein incorporated by reference in its entirety.
- An ornamental-flame burner generates a flame that is ornamental for the purpose of viewing. As examples, the burner may be used in a fire pit, fireplace, flame and water feature, etc. During operation of the burner, the flame is visible and the burner may be exposed or may be covered, entirely or partly, by an aggregate substrate (e.g., rock, stone, glass, etc.), faux logs (e.g., ceramic, steel, etc.), water, etc.
- In operation, it is desirable to generate a flame that is tall with a natural appearance similar to the appearance of flames of burning logs. Some burners generate short flames that are spaced from each other, thus having a non-natural appearance. These short flames may also be at least partly blue in color, which also deviates from the appearance of a natural fire. In addition, some burners are manufactured from materials that are aesthetically unappealing at initial installation and are subject to corrosion. One such example is black steel pipe.
- Other materials may have the benefit of better aesthetic appeal at installation and are resistant to corrosion. However, burners made of such materials are more costly to produce due to higher material cost, higher design and engineering cost, and higher manufacturing costs. Accordingly, it is desirable to design an ornamental-flame burner that maximizes the height and aesthetically pleasing appearance of the flame while reducing the cost to build by minimizing the amount of material used in manufacturing and assembly.

FIG. 7 is a perspective view of another example of the burner. - With reference to the Figures, wherein like numerals indicate like parts throughout the several views, a
burner 10 includes a plurality ofend nipples 12 and at least onejet 14 supported by and protruding outwardly from eachend nipple 12. The end nipples 12 and thejets 14 are brass. Eachend nipple 12 includes a first end 16 that is threaded and asecond end 18 that is closed. Eachend nipple 12 includes awall 20 extending from the first end 16 to thesecond end 18 and defines abore 22 extending through the first end 16 to thesecond end 18. Eachend nipple 12 includes a threadedhole 24 extending through thewall 20 to thebore 22. The first end 16 of theend nipple 12, thesecond end 18 of theend nipple 12, and thewall 20 of theend nipple 12 are unitary. Eachjet 14 includes a threadedportion 26 threadedly engaged with the threadedhole 24 and afuel combustion outlet 28 spaced from the threadedportion 26. - The
burner 10 generates a flame that is ornamental for the purpose of viewing. In other words, theburner 10 is an ornamental-flame burner. As examples, theburner 10 may be used in a fire pit, fireplace, water feature, etc. In use, the flame is visible and theburner 10 may be exposed or may be covered, entirely or partly, by an aggregate substrate (e.g., rock, stone, glass, etc.), faux logs (e.g., ceramic, steel, etc.), water, etc. - The
burner 10 is configured, as described further below, to generate an ornamental flame that is at least partly yellow and/or orange. In the examples shown in the figures, theburner 10 is configured to generate a flame that is all yellow and/or orange, i.e., from the point of combustion at thejet 14 to a tip of the flame distal to thejet 14. Specifically, theburner 10 is configured to discharge the fuel from thejet 14 at an air-to-fuel ratio to generate a flame that is yellow and/or orange. Theburner 10 is configured to burn a fuel-rich combustion mixture at an air-to-fuel ratio to generate the yellow color. Specifically, the fuel-rich combustion mixture generates the yellow and/or orange flame in contrast with a fuel-lean combustion mixture that generates a blue flame. Thejet 14 may generate a Venturi effect to mix air with the fuel to feed an air-to-fuel ratio at the point of combustion to generate a flame that is yellow and/or orange. For natural gas and propane, for example, theburner 10 may be configured to burn at approximately 1000-1200° C. to generate the yellow and/or orange color of the flame. - The
burner 10 is configured to generate a tall, dancing flame. This is generated, in part, by the flow rate of fuel to thejet 14 and the Venturi effect generated by thejet 14 to discharge the air-fuel combination at a high velocity. In addition, eachjet 14 generates a flame and each flame from eachjet 14 dances. In other words, thejets 14 are configured to discharge the air/fuel mixture such that the flame fluctuates in width and height during a stable fuel supply rate at aninlet coupling 34. The flames from theindividual jets 14 intermingle and/or combine. In some examples, the flames combine together by swirling based on the aim of thejets 14 relative to each other. The flames from all of thejets 14, in combination, dance. Theburner 10 described herein may operate, for example, at 60,000-450,000 BTU. For example, theburner 10 inFIG. 1 may operate at 100,000 BTU and theburner 10 inFIG. 7 may operate at 160,000 BTU. Thejets 14 shown inFIGS. 4A-C and 5A-C, for example, may each operate at 10,000 BTU. - The
burner 10 includes a plurality ofintermediate nipples 32, as discussed further below. The end nipples 12,intermediate nipples 32, andjets 14 in combination define a gas passageway to deliver fuel from theinlet coupling 34 to thejet 14. Thejet 14 releases the fuel to the atmosphere where the fuel is combusted as an ornamental flame. Theburner 10, including the end nipples 12,intermediate nipples 32, andjets 14, may be designed to deliver and burn any suitable type of gaseous fuel, including natural gas and propane. - As described further below, the footprint of the
burner 10 provides, at least in part, the generation of the tall, dancing flame. Specifically, the relative location of thejets 14, at least in part, generates the tall, dancing flame. As an example, the elongation of theend nipples 12 andintermediate nipples 32 along straight axes, respectively, that are transverse to each other provides the footprint to locate thejets 14 for generation of the tall, dancing flame. The axes of theintermediate nipples 32 may be perpendicular to the axes ofadjacent end nipples 12 to create the footprint of theburner 10 that provides, at least in part, the generation of the tall, dancing flame. - The
burner 10 is brass. Specifically, theintermediate nipples 32, the end nipples 12, thejets 14,fittings 50, and theinlet coupling 34 are brass. The brass is corrosion resistant, sustainable, and rust-proof. - One example of the
burner 10 is shown inFIG. 1 and another example of theburner 10 is shown inFIG. 7 . Common numerals are used to identify common features in the Figures. One example of thejet 14 is shown inFIGS. 4A-C and another example of thejet 14 is shown inFIGS. 5A-C and common numerals are used to identify common features inFIGS. 4A-5C . The example burners 10 shown inFIGS. 1 and 7 , by way of example, include thejet 14 ofFIGS. 4A-C . Alternatively, theburners 10 inFIGS. 1 and 7 may include thejets 14 ofFIGS. 5A-C . - The end nipples 12,
intermediate nipples 32, andjets 14 may be arranged in any suitable shape to position thejets 14 and aim thejets 14 to generate the tall, dancing flame. One example arrangement is shown inFIG. 1 and another example arrangement is shown inFIG. 7 . In the example shown inFIG. 1 , theburner 10 includes fourend nipples 12, sixintermediate nipples 32, and tenjets 14. In the example shown inFIG. 7 , theburner 10 includes eightend nipples 12, eightintermediate nipples 32, and sixteenjets 14. In other examples, theburner 10 may include any suitable number ofend nipples 12,intermediate nipples 32, andjets 14. - With reference to
FIGS. 1 and 7 , theinlet coupling 34 is connected to a fuel supply source (not shown) to deliver fuel to theburner 10. Theinlet coupling 34 may be of any suitable shape. For example, as shown inFIGS. 1 and 7 , theinlet coupling 34 may be T-shaped. As another example, theinlet coupling 34 may be straight. - The
inlet coupling 34 includes at least one threaded outlet (not numbered). For example, as shown inFIGS. 1 and 7 , theinlet coupling 34 includes two threaded outlets. In the examples shown inFIGS. 1 and 7 ,intermediate nipples 32 are directly connected to the threaded outlets of theinlet coupling 34, i.e., with the lack of any intermediate component therebetween. For example, theintermediate nipple 32 includes a thread threadedly engaged with the threaded outlet. In such an example, “directly connected” includes examples in which thread sealant is disposed between theintermediate nipple 32 and theinlet coupling 34. Theintermediate nipples 32 are supported by theinlet coupling 34. Specifically, a branch (not numbered) ofintermediate nipples 32, endnipples 12,fittings 50, andjets 50 is supported by theinlet coupling 34. The branch may be cantilevered from theinlet coupling 34, i.e., with all weight of the branch supported at theinlet coupling 34. The examples inFIGS. 1 and 7 include two branches, i.e., one branch supported by each threaded outlet of theinlet coupling 34. - The
inlet coupling 34 may be a standard coupling as known in industry. As an example, theinlet coupling 34 may be ¼-18 National Pipe Thread Taper (NPT) sized coupling available from any standard supplier. In such an example, the threaded outlet of theinlet coupling 34 have ¼-18 NPT threads and a standard corresponding sized and shaped body. - As set forth above, the
burner 10 includes a plurality of theintermediate nipples 32. With reference toFIGS. 2A and 2C , eachintermediate nipple 32 is elongated along a longitudinal axis Ai. In other words, the longest dimension of theintermediate nipple 32 is along the longitudinal axis Ai of theintermediate nipple 32. Specifically, theintermediate nipples 32 may be elongated in a common plane. During operation of theburner 10, the common plane may be horizontal. - With reference to
FIGS. 2A and 2C , eachintermediate nipple 32 includes two ends 36, 38 and aside 40 extending from oneend 36 to theother end 38. The ends 36, 38 and theside 40 of theintermediate nipple 32 are unitary, i.e., a single, continuous piece of material with no seams, joints, fasteners, welds, or adhesives holding it together. Eachintermediate nipple 32 may be formed as a unitary component, for example, by machining from a unitary blank, molding, forging, casting, etc. Non-unitary components, in contrast, are formed separately and subsequently assembled, e.g., by threaded engagement, welding, etc. In the example shown in the Figures, eachintermediate nipple 32 is formed by machining a brass bar, e.g., to include abore 42 and the other features of theintermediate nipple 32 described herein. - With reference to
FIGS. 2A and 2C , the ends 36, 38 are spaced from each other along the longitudinal axis Ai of theintermediate nipple 32. Eachintermediate nipple 32 may be straight from oneend 36 to theother end 38. Specifically, the longitudinal axis Ai of theintermediate nipple 32 may be straight. - With continued reference to
FIGS. 2A and 2C , both the first end 16 and thesecond end 18 are threaded, i.e., include threads (not numbered). The threads on theends ends ends inlet coupling 34 and threads on the fittings 50 (as described below). - With reference to
FIGS. 2B and 2C , thebore 42 of theintermediate nipple 32 is elongated along the longitudinal axis Ai. Thebore 42 extends through both ends 36, 38 of theintermediate nipple 32. In other words, both ends 36, 38 of theintermediate nipple 32 are open. When theburner 10 is assembled, thebore 42 creates the gas passageway extending through both ends 36, 38 of theintermediate nipple 32. - With continued reference to
FIGS. 2B and 2C , eachintermediate nipple 32 includes an outer diameter ODs and an inner diameter IDs. The inner diameter IDs defines thebore 42. Theintermediate nipple 32 has a wall thickness from the inner diameter IDs to the outer diameter ODs. Specifically, the wall thickness of theintermediate nipple 32 is measured radially relative to the longitudinal axis Ai from the inner diameter IDs to the outer diameter ODs. Theintermediate nipple 32 may be round, i.e., with a round outer diameter ODs and a round inner diameter IDs. - With reference to
FIGS. 2A-2C , theintermediate nipple 32 may include alanding 44 disposed between theends ends ends intermediate nipple 32 with theinlet coupling 34 and/or thefittings 50. The landing 44 may be disposed closer to oneend 36 of theintermediate nipple 32 than theother end 38 of theintermediate nipple 32. The landing 44 extends about theside 40 and has a width W1 along the longitudinal axis Ai of theintermediate nipple 32. The width W1 of the landing 44 of theintermediate nipple 32 may be between 0.4-0.5 inches. Specifically, in the example shown in the Figures, the width W1 of the landing 44 may be 0.45 inches. - The landing 44 includes circumferential surfaces meeting at vertices spaced circumferentially about the longitudinal axis Ai of the
intermediate nipple 32, i.e., the circumferential surfaces are angled relative to each other. The circumferential surfaces extend across the width W1 of thelanding 44, i.e., the circumferential surfaces extend along the longitudinal axis Ai of theintermediate nipple 32. - The circumferential surfaces may be engaged by a tool to transfer torque from the tool to the
intermediate nipple 32 for engaging the threads on theends intermediate nipple 32 with theinlet coupling 34 and/or thefittings 50. Specifically, eachintermediate nipple 32 may includeflats 46 at the landing 44 (i.e., the circumferential surfaces may be flats 46). Theflats 46 are planar. Theflats 46 each extend from one vertex to another vertex. The landing 44 may include sixflats 46 each meeting at the vertices, i.e., may be hexagonal, as shown in the examples in the Figures. As other examples, the landing 44 may include any suitable number offlats 46 that may meet at vertices or may be separated by round surfaces. As an example, the landing 44 may include twoflats 46 parallel to each other and spaced from each other by two round surfaces therebetween. - With reference to
FIGS. 2A-2C , eachintermediate nipple 32 includes a threadedhole 48 extending through theside 40 to thebore 42 for receiving one of thejets 14. The threaded holes 48 include threads. The threads match the threads of the threadedportion 26 of thejet 14. For example, the threads of the threadedholes 48 of theintermediate nipple 32 may be 1/16-27 NPT threads. - The threaded
hole 48 of eachintermediate nipple 32 may be disposed at any suitable position along the respectiveintermediate nipple 32. For example, as shown inFIGS. 1 and 7 , the threadedholes 48 of theintermediate nipples 32 may be disposed between oneend 36 and the landing 44 of theintermediate nipple 32. The threaded holes 48 may be in a same or different position on each respectiveintermediate nipple 32. - The
burner 10 may include any suitable number ofintermediate nipples 32. The example inFIG. 1 has sixintermediate nipples 32 and the example inFIG. 7 has tenintermediate nipples 32. A corresponding number of the intermediate nipples 32 (i.e., one for each threaded hole of the inlet coupling 34) are directly connected to theinlet coupling 34, i.e., with the lack of any intermediate component therebetween. In other words, theinlet coupling 34 may be a hub that feeds severalintermediate nipples 32 extending in different directions, e.g., as shown in the examples inFIGS. 1 and 7 . For example, as shown inFIGS. 1 and 7 , theburner 10 includes twointermediate nipples 32 directly connected to theinlet coupling 34, e.g., by threaded engagement with the threaded outlet of theinlet coupling 34. In such an example, “directly connected” includes examples in which thread sealant is disposed between the intermediate nipple 32 s and theinlet coupling 34. In the example including the twointermediate nipples 32 connected to theinlet coupling 34, theintermediate nipples 32 may be coaxial, i.e., elongated along a common axis A, as shown inFIGS. 1 and 7 . Theintermediate nipples 32 are supported by theinlet coupling 34. - Each
intermediate nipple 32 has a length Li along the longitudinal axis Ai of theintermediate nipple 32. The length Li extends from oneend 36 to theother end 38, as shown inFIG. 2A . Theintermediate nipples 32 may have common lengths or may have different lengths. In the example shown inFIG. 1 , theintermediate nipples 32 each have the same length Li. In the example shown inFIG. 7 , theburner 10 includesintermediate nipples 32 of two different lengths Li, specifically long intermediate nipples (also identified with reference numeral 66) and short intermediate nipples (also identified with reference numeral 68). In other words, the length Li of the long intermediate nipples 66 is larger than the length Li of the short intermediate nipples 68. In other examples, theburner 10 may includeintermediate nipples 32 of three or more lengths. - With reference to
FIGS. 1 and 7 , theburner 10 includes a plurality of thefittings 50. Theburner 10 includes a same number offittings 50 asintermediate nipples 32. In the example shown inFIG. 1 , theburner 10 includes sixfittings 50. In the example shown inFIG. 7 , theburner 10 includes eightfittings 50. Theintermediate nipples 32 and theend nipples 12 are connected to each other via thefittings 50. In other words, the gas passageway extends through thefittings 50. - The
fittings 50 are directly connected to therespective end nipples 12 andintermediate nipples 32, i.e., with the lack of any intermediate component therebetween. In such an example, “directly connected” includes examples in which thread sealant is dispose between the fitting 50 and therespective end nipple 12 andintermediate nipple 32. - The
fittings 50 may have any suitable shape. For example, thefittings 50 may be T-shaped, elbow-shaped, cross-shaped, etc. Each fitting 50 includes at least two threaded holes (not numbered). Thefittings 50 may be a standard fitting as known in industry. Thefittings 50 may be the same size as theinlet coupling 34. For example, the fitting may be ¼-18 National NPT sized fitting available from any standard supplier. In such an example, the threaded holes of the fitting 50 have ¼-18 NPT threads and a standard corresponding sized and shaped body. Thefittings 50 are brass, as set forth above. Additionally, one ormore fittings 50 may include a threaded opening (not shown) for receiving ajet 14. - With reference to
FIGS. 1 and 7 , eachend nipple 12 is connected to onefitting 50. For example, eachend nipple 12 is threadedly engaged with onerespective fitting 50. Eachend nipple 12 is supported by therespective fitting 50. Specifically, eachend nipple 12 is cantilevered from therespective fitting 50. - With reference to
FIGS. 3A and 3C , eachend nipple 12 is elongated along a longitudinal axis An. In other words, the longest dimension of theend nipple 12 is along the longitudinal axis An of theend nipple 12. The end nipples 12 may be elongated in a common plane. Specifically, theend nipples 12 and theintermediate nipples 32 may be elongated in a common plane. As describe above, during operation of theburner 10, the common plane may be horizontal. - With continued reference to
FIGS. 3A and 3C , eachend nipple 12 includes a first end 16, asecond end 18, and awall 20 extending from the first end 16 to thesecond end 18, as set forth above. The first end 16,second end 18, and thewall 20 of theend nipple 12 are unitary, i.e., a single, continuous piece of material with no seams, joints, fasteners, welds, or adhesives holding it together. Eachend nipple 12 may be formed as a unitary component, for example, by machining from a unitary blank, molding, forging, casting, etc. In the example shown in the Figures, eachend nipple 12 is formed by machining a brass bar, e.g., to include the gas passageway and the other features of theend nipple 12 described herein. - The first end 16 and the
second end 18 of theend nipple 12 are spaced from each other along the longitudinal axis An of theend nipple 12. Eachend nipple 12 may be straight from the first end 16 to thesecond end 18. Specifically, the longitudinal axis An of theend nipple 12 may be straight. As set forth above, theend nipple 12 may be cantilevered from the fitting 50. Specifically, thesecond end 18 is supported only by the connection of the first end 16 to the fitting 50. - With continued reference to
FIGS. 3A and 3C , the first end 16 is threaded, i.e., includes threads. The threads threadedly engage onerespective fitting 50. That is, the threads of eachend nipple 12 engage one respective threaded hole of onerespective fitting 50. The threads of the first end 16 match the threads of the threaded holes of thefittings 50. For example, the threads of the first end 16 may be ¼-18 NPT threads. - With reference to
FIG. 3C , thebore 22 of theend nipple 12 is elongated along the longitudinal axis An. Thebore 22 extends through the first end 16 of theend nipple 12 to thesecond end 18 of theend nipple 12. The first end 16 is open and thesecond end 18 is closed. In other words, thebore 22 extends through the first end 16 of theend nipple 12 and is plugged at thesecond end 18 of theend nipple 12. Thebore 22 of theend nipple 12 is elongated along the longitudinal axis An of theend nipple 12. - With continued reference to
FIG. 3C , eachend nipple 12, i.e., thewall 20, includes an outer diameter ODw and an inner diameter IDw. The inner diameter IDw defines thebore 22. Theend nipple 32 has a wall thickness from the inner diameter IDw to the outer diameter ODw. Specifically, the wall thickness of theend nipple 12 is measured radially relative to the longitudinal axis An from the inner diameter IDw to the outer diameter ODw. Theend nipple 32 may be round, i.e., with a round outer diameter ODw and a round inner diameter IDw. The outer diameter ODw of theend nipple 12 may be the same as the outer diameter ODs of theintermediate nipple 32, and the inner diameter IDw of theend nipple 12 may be the same as the inner diameter IDs of theintermediate nipple 32. - With continued reference to
FIGS. 3A and 3C , theend nipple 12 includes ahead 52 at thesecond end 18. Thehead 52 can be rotated to threadedly engage the threads of the first end 16 with therespective fitting 50. Thehead 52 has a width Wh extending along the longitudinal axis An of theend nipple 12, e.g., from thesecond end 18 towards the first end 16. The width Wh of thehead 52 of theend nipple 12 may be between 0.9-1.1 inches. For example, the width Wh of thehead 52 may be 1.0 inches. - With reference to
FIG. 3B , thehead 52 includes circumferential surfaces meeting at vertices spaced circumferentially about the longitudinal axis An of theend nipple 12, i.e., the circumferential surfaces are angled relative to each other. The circumferential surfaces extend across the width Wh of thehead 52, i.e., the circumferential surfaces extend along the longitudinal axis An of theend nipple 12. - The circumferential surfaces may be engaged by a tool to transfer torque from the tool to the
end nipple 12 for engaging the threads of the first end 16 with a fitting 50. Specifically, eachend nipple 12 may includeflats 46 at the head 52 (i.e., the circumferential surfaces may be flats 46). Theflats 46 are planar. Theflats 46 each extend from one vertex to another vertex. Thehead 52 may include sixflats 46 each meeting at the vertices, i.e., may be hexagonal, as shown in the examples in the Figures. As other examples, thehead 52 may include any suitable number offlats 46 that may meet at vertices or may be separated by round surfaces. As an example, thehead 52 may include two flats parallel to each other and spaced from each other by two round surfaces therebetween. - With reference to
FIGS. 3A-3C , eachend nipple 12 includes a threadedhole 24 extending through thewall 20 to thebore 22 for receiving one of thejets 14. The threadedhole 24 includes threads. The threads match the threads of the threadedportion 26 of thejet 14. For example, the threads of the threadedhole 24 may be 1/16-27 NPT threads. In other words, the threads of the threadedhole 24 of theend nipple 12 match the threads of the threadedhole 48 of theintermediate nipple 32. - The threaded
hole 24 may be disposed at any suitable position along theend nipple 12. For example, as shown inFIGS. 1 and 7 , the threadedhole 24 of eachend nipple 12 may be disposed on thehead 52 of theend nipple 12. In other words, the threadedhole 24 may extend through one of theflats 46 to thebore 22. As another example, the threadedhole 24 may be disposed between thehead 52 and the first end 16 of theend nipple 12. The threadedhole 24 may be in a same or different position on eachend nipple 12. - Each
end nipple 12 has a length Ln along the longitudinal axis An of theend nipple 12. The length Ln extends from the first end 16 to thesecond end 18 of theend nipple 12, as shown inFIG. 3A . The end nipples 12 may have any suitable length Ln. For example, eachend nipple 12 may have the same length Ln, as shown inFIGS. 1 and 7 . As another example, at least oneend nipple 12 may have a different length Ln than anotherend nipple 12. - With reference to
FIGS. 1 and 7 , theburner 10 includes a plurality ofjets 14. As set forth above, one example of thejet 14 is shown inFIGS. 4A-C and another example of the jet is shown inFIGS. 5A-C . - The
burner 10 may include any suitable number ofjets 14 connected to theend nipples 12 and theintermediate nipples 32. Eachend nipple 12 supports at least onejet 14. In the example shown in the Figures, eachend nipple 12 and eachintermediate nipple 32 support onejet 14. As other examples, eachend nipple 12 may support any suitable number ofjets 14, i.e., one or more, and eachintermediate nipple 32 may support zero or any suitable number ofjets 14. As another example,jets 14 may be supported by thefittings 50. - Each
jet 14 is connected to therespective end nipple 12,intermediate nipple 32, or fitting 50. For example, eachjet 14 is threadedly engaged with therespective end nipple 12,intermediate nipple 32, or fitting 50. In other words, eachjet 14 is formed separately from and subsequently attached to therespective end nipple 12,intermediate nipple 32, or fitting 50. - The
jet 14 protrudes outwardly from therespective end nipple 12,intermediate nipple 32, or fitting 50. With reference toFIGS. 4A and 5A , eachjet 14 is elongated along a longitudinal axis Aj. In other words, the longest dimension of thejet 14 is along the longitudinal axis Aj of thejet 14. Eachjet 14 includes aproximate end 54 and afuel combustion outlet 28 spaced from each other along the longitudinal axis Aj of thejet 14. Thejet 14 is cantilevered from theend nipple 12,intermediate nipple 32, or fitting 50, i.e., thefuel combustion outlet 28 is supported only by the connection of thejet 14 to therespective end nipple 12,intermediate nipple 32, or fitting 50. Eachjet 14 may be straight from theproximate end 54 to thefuel combustion outlet 28. Specifically, the longitudinal axis Aj of thejet 14 may be straight. - The
jets 14 may be aimed in any suitable direction to generate the tall, dancing flame. The longitudinal axis Aj of thejet 14 extends upwardly from the common plane at a non-right angle. Accordingly, the flame from alljets 14 combine into a single flame that is generally conical. - With reference to
FIGS. 4A and 5A , eachjet 14 includes a threadedportion 26 and abarrel 30, as set forth above. The threadedportion 26 and thebarrel 30 are unitary, i.e., a single, continuous piece of material with no seams, joints, fasteners, welds, or adhesives holding it together. Eachjet 14 may be formed as a unitary component, for example, by machining from a unitary blank, molding, forging, casting, etc. In the example shown in the Figures, eachjet 14 is formed by machining a brass bar, e.g., to include the gas passageway and the other features of thejet 14 described herein. - With reference to
FIGS. 4A, 4C, 5A, and 5C , the threadedportion 26 extends from theproximate end 54 towards thefuel combustion outlet 28 along the longitudinal axis Aj of thejet 14. The threadedportion 26 is threaded, and specifically, includes male threads. The threads of the threadedportion 26 may have any suitable size. The threads of the threadedportion 26 are the same size as the threads of the threadedholes end nipples 12 andintermediate nipples 32. For example, the threads of the threadedportion 26 may be 1/16-27 NPT threads. - The threaded
portion 26 includes a length Lt extending along the longitudinal axis Aj of thejet 14. The length Lt extends from theproximate end 54 towards thefuel combustion outlet 28, as shown inFIGS. 4C and 5C . The threadedportion 26 may extend into thebore 22 of theend nipple 12 when thejet 14 is connected to theend nipple 12, and into thebore 42 of theintermediate nipple 32 when thejet 14 is connected to theintermediate nipple 32, as shown inFIGS. 6A and 6B . - The
jets 14 are in communication with thebores end nipples 12 and theintermediate nipples 32. With reference toFIGS. 4C and 5C , thejet 14 includes an inlet bore 56 extending through the threadedportion 26 towards thefuel combustion outlet 28 and abore 60 extending from the inlet bore 56 through thefuel combustion outlet 28. The inlet bore 56 and thebore 60 are open to each other. A diameter Di of the inlet bore 56 may be constant through the threadedportion 26. For example, the diameter Di of the inlet bore 56 may be constant from theproximate end 54 to thebore 60. Theproximate end 54 may be chamfered at the inlet bore 56. The inlet bore 56 is in communication with thebores respective end nipples 12 orintermediate nipples 32. - The
barrel 30 extends from thefuel combustion outlet 28 towards the threadedportion 26. As one example, as shown inFIGS. 4A and 4C , thebarrel 30 is spaced from the threadedportion 26. In such an example, thejet 14 includes a taperingportion 58 between thebarrel 30 and the threadedportion 26. The taperingportion 58 extends from thebarrel 30 to the threadedportion 26. The taperingportion 58 includes an outer diameter that tapers from thebarrel 30 to the threadedportion 26. That is, the outer diameter of the taperingportion 58 decreases along the longitudinal axis Aj of thejet 14 from thebarrel 30 to the threadedportion 26. The taperingportion 58 may have any suitable length along the longitudinal axis Aj of thejet 14. The taperingportion 58 may have any suitable full taper angle. As another example, as shown inFIGS. 5A and 5C , thebarrel 30 extends to the threadedportion 26. - The
barrel 30 extends annularly about the longitudinal axis Aj of thejet 14. Thebarrel 30 defines thebore 60 extending along the longitudinal axis Aj of thejet 14. A diameter Db of thebore 60, e.g., at thefuel combustion outlet 28, is larger than the diameter Di of the inlet bore 56, as shown inFIGS. 4B, 4C, 5B and 5C . The diameter Db of thebore 60 may taper to the diameter Di of the inlet bore 56 at acountersink 70 from thebore 60 to the inlet bore 56. The diameter Db of thebore 60 may be constant from thefuel combustion outlet 28 to thecountersink 70 and the diameter Di of the inlet bore 56 may be constant from thecountersink 70 to theproximate end 54. The diameter Db of thebore 60 may be constant from thefuel combustion outlet 28 to the taperingportion 58 and the diameter Di of the inlet bore 56 may be constant from the taperingportion 58 through the threadedportion 26. - The
barrel 30 has an outer diameter ODb, as set forth above. The outer diameter ODb of thebarrel 30 may be constant along the longitudinal axis Aj of thejet 14. For example, as shown inFIGS. 4A and 4C , the outer diameter ODb of thebarrel 30 is constant from thefuel combustion outlet 28 to the taperingportion 58. In such an example, the outer diameter ODb of thebarrel 30 is larger than an outer diameter of the threadedportion 26. As another example, as shown inFIGS. 5A and 5C , the outer diameter ODb of thebarrel 30 is constant from thefuel combustion outlet 28 to the threadedportion 26. In such an example, the outer diameter ODb of thebarrel 30 is the same as the outer diameter of the threadedportion 26. Thebarrel 30 includes a wall thickness extending radially about the longitudinal axis Aj of thejet 14. - The
jet 14 includes ahead 62 at thefuel combustion outlet 28, as shown inFIGS. 4A and 5A . Thehead 62 can be rotated to threadedly engage the threads with theend nipple 12, theintermediate nipple 32, or the fitting 50. Thehead 62 has a width Wb extending along the longitudinal axis Aj of thejet 14, e.g., from thefuel combustion outlet 28 towards the threadedportion 26. The width Wb of thehead 62 of thejet 14 is between 0.2-0.3 inches. For example, the width Wb of thehead 62 may be 0.25 inches. - With reference to
FIGS. 4A, 4B, 5A, and 5B , thehead 62 includes circumferential surfaces meeting at vertices spaced circumferentially about the longitudinal axis Aj of thejet 14, i.e., the circumferential surfaces are angled relative to each other. The circumferential surfaces extend across the width Wb of thehead 62, i.e., the circumferential surfaces extend along the longitudinal axis Aj of thejet 14. - The circumferential surfaces may be engaged by a tool to transfer torque from the tool to the
jet 14 for engaging the threads of the threadedportion 26 with theend nipple 12, theintermediate nipple 32, or the fitting 50. Specifically, eachjet 14 may includeflats 46 at the head 62 (i.e., the circumferential surfaces may be flats 46). Theflats 46 are planar. Theflats 46 each extend from one vertex to another vertex. Thehead 62 may include sixflats 46 each meeting at the vertices, i.e., may be hexagonal, as shown in the examples in the Figures. As other examples, thehead 62 may include any suitable number offlats 46 that may meet at vertices or may be separated by round surfaces. As an example, thehead 62 may include twoflats 46 parallel to each other and spaced from each other by two round surfaces therebetween. - With reference to
FIG. 4C , thejet 14 is designed to resist breakage during installation (e.g., during application of torque to thehead 62 of thejet 14 to tighten the threaded engagement of thejet 14 to the threadedhole 24, 48) and during handling (including potential dropping of the jet 14). As one example, thebore 60 terminates in thebarrel 30. Specifically, the end of thebore 60 in thebarrel 30, e.g., at thecountersink 70, is aligned along the longitudinal axis Aj of thejet 14 between the taperingportion 58 and thefuel combustion outlet 28. Such a configuration provides a wall thickness suitable to withstand torque applied to thehead 62 of thejet 14 during installation and handling. In examples including thecountersink 70, thecountersink 70 terminates at one end aligned along the longitudinal axis Aj of thejet 14 with thebarrel 30 and terminates at another end aligned along the longitudinal axis Aj of thejet 14 with the taperingportion 58. The inlet bore 56 terminates at an end aligned along the longitudinal axis Aj of thejet 14 with the taperingportion 58. Thecountersink 70 between thebore 60 and the inlet bore 56 provides sufficient wall thickness for installation and handling of thejet 14. - The
barrel 30 has a length Lb along the longitudinal axis Aj of thejet 14. The length Lb of thebarrel 30 extends from thefuel combustion outlet 28 towards the threadedportion 26. As shown inFIGS. 4A and 4C , the length Lb of thebarrel 30 extends from thefuel combustion outlet 28 to the taperingportion 58. As shown inFIGS. 5A and 5C , the length Lb of thebarrel 30 extends from thefuel combustion outlet 28 to the threadedportion 26. Thebarrel 30 may have any suitable length. - The
barrel 30 includes at least oneoxygen hole 64 extending through thebarrel 30 to thebore 60 of thejet 14. For example, thebarrel 30 includes oneoxygen hole 64 when the fuel is natural gas, as shown inFIGS. 4A and 4C . As another example, thebarrel 30 includes twooxygen holes 64 when the fuel is propane. In such an example, the twooxygen holes 64 may be spaced diametrically from each other, as shown inFIGS. 5A and 5C . - The
oxygen hole 64 may be disposed at any suitable position along thebarrel 30. That is, theoxygen hole 64 may be disposed between the threadedportion 26 and thefuel combustion outlet 28. For example, theoxygen hole 64 may be disposed between the threadedportion 26 and thehead 62 of thebarrel 30. As another example, theoxygen hole 64 may be disposed on thehead 62 of thebarrel 30. In such an example, theoxygen hole 64 may extend through one flat of thehead 62. Theoxygen hole 64 includes a diameter Do. The position and the diameter Do of theoxygen hole 64 may be selected to achieve the yellow flame. - Each
jet 14 has a length Lj along the longitudinal axis Aj of thejet 14. The length Lj extends from theproximate end 54 to thefuel combustion outlet 28 of thejet 14. Thejets 14 may have any suitable length. For example, eachjet 14 may have the same length Lj. - The
intermediate nipples 32, the end nipples 12, and thejets 14 may be specially manufactured for theburner 10 disclosed herein. As set forth above, in the example shown in the Figures, the end nipples 12,intermediate nipples 32, andjets 14 are formed by machining a brass bar, i.e., to include thebores intermediate nipples 32, endnipples 12, andjets 14 may be designed and manufactured to have the size and shape to generate the tall, dancing flame having yellow and/or orange color, as described above. The designs shown in the Figures and the dimensions disclosed herein generate the tall, dancing flame having yellow and/or orange color. - The lengths Li of each
intermediate nipples 32 and the lengths Ln of eachend nipple 12 create the footprint of theburner 10 that provides, at least in part, the generation of the tall, dancing flame. The length Li of eachintermediate nipple 32 may be between 5.5-6.5 inches. For example, In the example shown inFIG. 1 , the length Li of eachintermediate nipple 32 may be 6 inches. In the example shown inFIG. 7 , the long intermediate nipples 66 may have a length Li between 5.5-6.5 inches and the short intermediate nipples 68 may have a length between 2-3 inches. Specifically, in the example shown inFIG. 7 , the length Li of the long intermediate nipples 66 may be 6 inches, and the length Li of the short intermediate nipples 68 may be 2.375 inches. - In the example shown in
FIG. 1 , the length Ln of eachend nipple 12 may be between 4 and 5 inches. For example, the length Ln of eachend nipple 12 may be 4.5 inches. In the example shown inFIG. 7 , the length Ln of eachend nipple 12 is between 2 and 3 inches. For example, the length Ln of eachend nipple 12 may be 2.375 inches. - As set forth above, the outer diameter ODw of the
end nipple 12 may be the same as the outer diameter ODs of theintermediate nipple 32, and the inner diameter IDw of theend nipple 12 may be the same as the inner diameter IDs of theintermediate nipple 32. The outer diameters ODw, ODs of theintermediate nipple 32 and theend nipple 12 are between 0.5-0.6 inches. For example, the outer diameters ODw, ODs of theintermediate nipple 32 and theend nipple 12 may be 0.54 inches. The inner diameters IDw, IDs of theintermediate nipple 32 and theend nipple 12 are between 0.3-0.4 inches. For example, the inner diameters IDw, IDs of theintermediate nipple 32 and theend nipple 12 may be 0.375 inches. The wall thickness of each of theintermediate nipples 32 and the end nipples 12 may be between 0.15-0.18 inches. This inner diameter IDw, IDs provides suitable gas flow to generate the tall, dancing flame having yellow and/or orange color, and this outer diameter, inner diameter, and wall thickness advantageously minimizes the material, i.e., brass, of theend nipple 12 andintermediate nipple 32 to reduce material cost in manufacturing. - As set forth above, the threads of the threaded
portion 26 may be 1/16-27 NPT threads. In such an example, the threadedportion 26 may have an outside diameter of 0.3125 inches. These dimensions of the threadedportion 26 encourage proper seating of the threadedportion 26 against therespective end nipple 12 or theintermediate nipple 32 of the dimensions described above (e.g., 0.54 inch outer diameter; 0.375 inch inner diameter; and 0.15-0.18 inch wall thickness) when threadedly engaged with the threadedhole - In the example shown in
FIGS. 4A-C , the taperingportion 58 allows for proper seating of the threadedportion 26 against therespective end nipple 12 orintermediate nipple 32; allows for sufficient gas flow to generate the tall, dancing flame having yellow and/or orange color; and provides robustness to resist breakage during installation and handling. Specifically, the taperingportion 58 provides material for sufficient wall thickness at the end of thebore 60, e.g., at thecountersink 70. For example, as described above, the end of thebore 60 is aligned along the longitudinal axis Aj of thejet 14 between the taperingportion 58 and thefuel combustion outlet 28. Such a configuration provides a wall thickness suitable to withstand torque applied to thehead 62 of thejet 14 during installation and handling. - In addition, with continued reference to
FIGS. 4A-C , the outer diameter ODb of thebarrel 30 may be between 0.3-0.5 inches. For example, the outer diameter ODb of thebarrel 30 may be 0.4 inches. This outer diameter ODb allows for suitable gas flow through thejet 14 to generate the tall, dancing flame having the yellow and/or orange color. Specifically, the diameter Db of thebore 60 at thefuel combustion outlet 28 may be between 0.2-0.3 inches. For example, the diameter Db of thebore 60 at thefuel combustion outlet 28 may be 0.25 inches. The wall thickness of thebarrel 30 may be between 0.1-0.2 inches. For example, the wall thickness of thebarrel 30 may be 0.15 inches. - With continued reference to
FIG. 4C , the size of the diameter Db of thebore 60 may be between 75%-85% the size of the outer diameter of the threadedportion 26. In the example shown inFIG. 4C , the size of the diameter Db of thebore 60 is 80% the size of the outer diameter of the threadedportion 26. For example, as described above, the diameter Db of thebore 60 may be 0.25 inches ant the outer diameter of the threadedportion 26 may be 0.3125 inches. This allows for sufficient gas flow from thefuel combustion outlet 28 to generate the tall, dancing flame having the yellow and/or orange color and a proper seating of the threadedportion 26 against therespective end nipple 12 or theintermediate nipple 32 while still being robust to resist breakage during installation and handling. - With continued reference to
FIG. 4C , the wall thickness of the taperingportion 58 increases from thebarrel 30 to the threadedportion 26. This increases the robustness of thejet 14 to resist breakage during installation and handling. The diverging angles of thecountersink 70 and the taperingportion 58 creates the increasing wall thickness from thebarrel 30 to the threadedportion 26, as shown inFIG. 4C . - With reference to
FIGS. 5A-C , thejet 14 may have a constant outer diameter from theproximate end 54 to thefuel combustion outlet 28. For example, the outer diameter of thejet 14 inFIGS. 5A-C may be 0.25-0.35 inches. As one example, the outer diameter of thejet 14 inFIGS. 5A-C may be 0.3125 inches. - The diameter Do of the
oxygen hole 64 may be between 0.02-0.1 inches. For example, the diameter Do of theoxygen hole 64 may be 0.086 inches. This diameter Do of theoxygen hole 64 provides quiet operation of theburner 10. - The length Lj of each
jet 14 is between 0.9-1.1 inches. For example, the length Lj of eachjet 14 may be 1.0 inches. The length Lt of the threadedportion 26 is between 0.2-0.3 inches. For example, the length Lt may be 0.26 inches. This length Lj minimizes the material usage in manufacturing thejet 14 while allowing for sufficient gas flow from thefuel combustion outlet 28 to generate the tall, dancing flame having the yellow and/or orange color. - In the example shown in
FIGS. 4A-4C and 6A , the length Lb of thebarrel 30 is between 0.6-0.7 inches. For example, the length Lb of thebarrel 30 may be 0.64 inches. Additionally, the taperingportion 58 extends, e.g., 0.1 inches, from thebarrel 30 to the threadedportion 26. Further, the taperingportion 58 may have a full taper angle of 60 degrees. - In the example, shown in
FIGS. 5A-5C and 6B , the length Lb of the barrel is between 0.73-0.75 inches. For example, the length Lb of thebarrel 30 may be 0.74 inches. - The disclosure has been described in an illustrative manner, and it is to be understood that the terminology which has been used is intended to be in the nature of words of description rather than of limitation. Many modifications and variations of the present disclosure are possible in light of the above teachings, and the disclosure may be practiced otherwise than as specifically described.
