HERMAN W. WILKERSON ATTORNEY FUEL BURNER CROSSOVER ARRANGEMENT BACKGROUND OF THE INVENTION This invention relates to fuel burners and more particularly to an improved crossover arrangement for ignition of adjacent fuel burners.
For safety reasons, it is desirable that the ignition of any one burner in a plurality of burners cause rapid ignition of the remaining burners. Such an arrangement is also desirable because it permits the fuel burning apparatus to be ignited with a single pilot. It is, therefore, common practice to provide a transverse fuel passage between adjacent burners which is known as a crossover. The crossover is disposed adjacent a similar crossover of an adjacent burner and is provided with a transverse fuel port. A pilot assembly is located for igniting the fuel discharged from the crossover port of one of the crossovers. When the first crossover is ignited, the flame spreads to ignite its associated fuel burner and the adjacent crossover ports which, in turn, ignite their associated burners. Difficulties have been experienced with prior crossover arrangements in dependably and smoothly igniting their associated burners due to the crossover tending to interfere with fuel flow to the closely adjacent portion of the burner fuel ports. If the fuel ports adjacent the crossover member are starved for fuel, ignition of its associated burner becomes-unreliable and slow. In extreme cases, an explosion hazard may be encountered due to excessive gas being discharged into the combustion chamber before the burner ignites.
SUMMARY OF THE INVENTION In accordance with this invention, there is provided a burner for a fuel mixture having a generally elongated burner body with suitable port means such as a series of slots or louvers for discharging fuel to be burned along a substantial portion of the axial length of the burner body. A crossover fuel aperture is formed in the burner body adjacent the fuel inlet end. A crossover body having a generally transverse passage is formed with a corresponding crossover fuel inlet aperture. 1-1 depending scoop element extends from the downstream edge of the fuel aperture in the crossover body to deflect fuel from the burner body into the crossover. In addition, the scoop serves as a locating means for assembling the crossover body on ,the burner body and effectively forms a seal with the burner body to inhibit the escape of fuel from between the burner and the crossover.
An aperture is formed in the scoop element to permit a portion of fuel gas to bypass the scoop and flow directly to the burner fuel ports adjacent the crossover body to insure an adequate supply of fuel to the adjacent burner ports for dependable lighting of the burner. 1
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an isometric view of a fuel burner assembly illustrating one of the burners and crossovers in exploded fashion;
FIG. 2 is a cross section through an assembled bumer and crossover; and
FIG. 3 is an enlarged perspective view of the underside of the bottom member of the crossover.
DESCRIPTION OF THE PREFERRED EMBODIMENT Fuel burner assembly 10 is illustrated as including a plurality of generally cylindrical, elongated fuel burner bodies secured with respect to a gas manifold 11 which is provided with a plurality of spaced gas orifices l2 and a corresponding mounting stud 13 adjacent each gas orifice. Burner bodies 16, 17, 18 are provided with burner fuel ports 19 which extend along a substantial portion of the axial length of the burner bodies. Fuel ports 19 in the illustrated embodiment comprise a plurality of transverse slots or louvers centrally disposed across the top side of a generally cylindrical burner body, although it will be appreciated that any type of fuel porting such as one or more axial slots may be employed.
A crossover body or member 30 which comprises a generally transverse fuel passage is provided on each burner body for ignition of adjacent fuel burners. In the embodiment illustrated, the crossover is formed of a pair of sheet metal stampings which include a top member 31 and a bottom member 32. Top member 31 has a downwardly protruding dimple 34 and an upwardly expanded portion 35. The bottom portion of the crossover member 32 has a downwardly expanded portion 36. When top member 31 is assembled with bottom member 32, a generally transverse hollow fuel passage is formed in the crossover body. Dimple 34 rests on the flat peripheral rearward edge of bottom member 32 so that the forward and side edges of the top and bottom members are spaced to form a crossover fuel port 33 along the entire rearward edges of crossover 30. The top and bottom members of the crossover member are secured to each other by suitable means such as spot welds 37. The transverse fuel passage in crossover 30 of the preferred embodiment is shaped so as to provide a tapering fuel passage as illustrated in the drawings in order to equalize the gas pressure and provide an even length of flame along the entire rearward edge of the crossover when ignited. The arrangement illustrated provides a very simple twopiece crossover member which requires only two stampings and a spot welding operation to complete. However, it will be appreciated that other types of crossover bodies may be employed if desired.
In accordance with this invention, bottom member 32 of the crossover member is formed with a crossover fuel inlet aperture 39. A scoop element 40 extends axially forwardly and downwardly from the downstream or rearward edge of bottom member 32. As illustrated in the drawing, scoop element 40 is preferably formed by a pair of tabs 41 and 42 which are split and slightly spread along their axis to form a central aperture or slot 43 in axial alignment with the crossover and burner bodies. Crossover fuel inlet opening 39 and scoop 40 are preferably formed simultaneously during the stamping operation which forms bottom member 32 by simply stamping a downwardly extending pair of tabs from the parent metal of member 32. Scoop element 40 preferably has a spherically contoured shape with a substantially triangular shaped opening defined by the.
spaced edges of the tabs'forming the scoop element and defines a rectangular or semicircular crossover fuel inletaperture in crossover body 30. I
The two members 31, 32 forming the crossover body are first secured to each other by some suitable means such as spot welds 37. The crossovermember 30 is then positioned on top of burner body 18 with scoop element 40 extending downwardly into the hollow burner body through crossover fuel aperture 27. The distance between the transverse edges of scoop element 40 at their junction with the bottom of crossover body 30 is substantially the same as the transverse dimension of aperture 27 and the axial dimension of aperture 39 may be substantially the same as the axial dimension of aperture 27 so that scoop 40 forms a locating means for crossover 30 on the burner. Consequently, the crossover member is accurately aligned in the desired posi-' tion on the burner body without the need of fixtures or other locating means. The flange portions 45 of crossover 30 are then secured to flange 46 on the burner body by suitable means such as spot welds 38.
In operation, a plurality of assembled burner bodies and crossover members are positioned in spaced relation along gas manifold 11. A suitable pilot assembly 50 is disposed adjacent at least one of the crossover members so that the pilot flame can impinge on fuel port 33 of the crossover. When gas is supplied from the manifold into the burner bodies, a portion of the fuel mixture is passed upwardly into the crossovers and discharged into the region of the pilot flame. The pilot ignites the fuel discharged from the crossover and spreads transversely from crossover to crossover until each of the crossovers is ignited. At the same time when the flame reaches the rear edge of the crossover,
it ignites fuel discharged from the fuel ports in 19 adjacent the crossover. Aperture 43 in the scoop elements allows fuel to pass directly through the scoop .element aperture to the fuel ports 19 most closely adjacent the rear edge of the crossover. Consequently, the scoop does not excessively reduce the supply of fuel to the portion of the burner ports adjacent the crossover port so that rapid and highly reliable ignition of the burners is achieved.
It will be seen that byproviding a crossover with a scoop element in accordance with this invention, the speed and reliability of the main burner ignition is improved while, at thesame time, the scoop element serves as a locating means for the crossover during manufacture and as a seal to reduce escape of fuel from between the burner body and crossover member.
While a preferred embodiment of this invention has been described for purposes of illustration, it will be appreciated that this I invention may be otherwise embodied within the scope of the following claims.
