Application filed October 2,1929. serial No, 396,655.
The present invention relates, generally,
to burners of fluid or gaseous fuels; and the invention has reference, more particularly, to a novel and improved multiple or gang burner of the Bunsen type. i
Burners of this type as have heretofore been commonly constructed are often objectionable because of their failure to thoroughly intermix the gaseous fuel and air in the proper proportions resultingin uncertain and inefficient heating duction of obnoxious gases. 3
'Ilie principalobject of the present inven-, tion is to provide a novel burner which is so constructed and arranged as to insure a com-. plete and thorough intermixing of the fluid fuel with the proper quantity of air, whereby a complete and efficient combustion of the fuel is obtained. V I p Another. object of the invention "lies in the provision of a burner of the above character wherein intense. combustion. is aided and sustained by providing means for preheating the combustible mixture and for partially enclosing the path of the burning fuel, thereby protecting the latter from extraneous currents of air and from the chilling effects of the surrounding atmosphere.
Still another object of the invention is to provide a burner of the above character which is of simple construction and reliable in operation.
Other objects of this invention, not at this ime more particularly.enumerated, will be clearly understood from the following detailed description of the same.
The invention is clearly illustrated in. the accompanying drawings in which F ig. 1 is a view in front elevation with taken along line 22 of Fig. 1;
Fig. 3 is a sectional view taken along line Fig. 4 is a perspective view with parts brokenaway of. the chimneyof said burner;
I Fig. 7 is a perspective view illustrating the relative positions ofthe fuel supply pipe and air supply regulating slide. I
. Similar characters of'reference are employed in all of the hereinabove described views, to indicate corresponding parts.
1 PATENT orsics 1 Referring now to the said drawings; the
novel burner of this invention is designated as a whole by the reference numeral land comprises a base 2, upon which ismounted a pair of opposed mixing blocks 3and 4: which in turn support a chimney 5. These several viewed in plan, having legs 6 and a depend:
ing peripheral apron 7 at its sidesand ends. The apron 7 at the ends of the base 2 has aligned segmental recesses 9 and 10 provided therein forreceiving the end portions of a fuel supply pipe 11. Fuel supplypipe 11 is heldin engagement with the recesses 9'an 10 and in assembled relation with respect'to the base '2 by U-shaped straps 12 that extend around the under surface of the supply pipe and have their upper end ortions secured by bolts 13 to the base 2. reduced at one end providingan intake nipple le ada pted for connection to a suitable fuel supply hose 15. A valve 16 is illustrated as provided in the intake nipple 14.
Supply pipe 11 has a plurality of pipes or jets 18 threaded thereinto and extending upwardly therefrom. Jets 18 project upwardly through longitudinally arranged slots 19 provided in an air supply regulating'slide20 and through c'ircularapertures 21 provided in the base 2. Air regulating slide 20 has its upper surface in contact with the under surface of the base 2 and is supported for lim- 7 ited longitudinal sliding movement in guide. ways 22 provided in this base. The sliding movement ofslide 20 is limited by the ends of slots 19 striking jets 18. Air regulating slide 20 is provided with two longitudinal rows of circular air inlet apertures 23 at the sides of theslots 19. Air inlet apertures .23
are adapted to underlie similar apertures 24 provided in the base 2. Slide 20 is provided with a handle 25 at one end thereof. By manipulating the handle portion 25, the slide 20 may be moved longitudinally so that the air inlet apertures 23 are either partially or fully aligned with apertures 24, thereby permit ting air to pass upwardly from below and through the base 2 on opposite sides of jets 18. The amount of air that is allowed to pass upwardly through apertures 23 and 24 depends upon the degree of alignment of these apertures, being a maximum when these apertures are fully aligned and being reduced as apertures 23 are moved out of alignment with apertures 24.
Mixing blocks 3 and 4 are similar and are positioned in opposed relation to one another upon the base 2 and are attached to this base by the bolts 13. These blocks are provided on their opposed inner surfaces with a series of cooperating vertically extending mixing grooves 27 of semi-circular cross-section which grooves are axially and vertically aligned with the jets 18. The lower portions of these grooves are beveled at 28 so as to enable air passing up through apertures 23 and 24 to readily enter the mixing grooves. The mixing grooves 27 of the mixing block 3 arelargely separated from opposed grooves 27 of block 4 by adividing plate 30. A limited communication between these grooves of the opposed blocks is permit-ted'just above jets 18 by a series of circular apertures 31 provided in the dividing plate 30. The lower edge of dividing plate rests directly upon base 2 and upon the tops of jets 18 and serves to divide or split the stream of gaseous fuel emitting from each of these jets into two substantially equal streams, one such stream passing up a groove 27 of mixing block 3 while the other similar stream passes up a groove 27 of block 4.
The outer surfaces of mixing blocks 3 and i 4 are channeled to provide a plurality of spaced vertical heat radiating ribs 32 terminating adjacent the top and bottom of these blocks.
The chimney 5 is mounted in superimposed relation to the tops of the mixing blocks 3 and 4 and is secured to these blocks as by screws 35 extending through apertures in the base 36 of this chimney 5 and threaded into the mixing blocks. The base 36 is provided with T a series of spaced discharge apertures 37 which are aligned with mixing grooves 27 of mixing blocks 3 and 4. Side walls 38 and 39 and rear wall 40 extend upwardly from base 36 and support a rearwardly and downwardly inclined baffle 41 at their upper ends.
Bafiie 41 serves to direct the hot products of combustion forwardly and into the room in which the heater is installed. Obviously this baffle may be omitted in many instances. A plurality of directing ribs 43 are formed on the baflie 41 and rear wall 40 and extend for wardly between the discharge apertures 37. Ribs 43 terminate above base 36 in spaced relation therefrom, thereby enabling a max imum flow of air towards and among the flaming jets issuing from the discharge apertures 37.
In operation, the supply of gaseous fuel issuing from hose 15 is controlled by valve 16. This fuel passes through supply pipe 11 and jets or pipes 18 into the mixing grooves 27. The upward movement of the fuel in grooves 27 serves to draw air from below base 2 up through apertures 23 and 24 into the mixing grooves. The presence of dividing plate 30 serves to give the upwardly moving gases within the mixing grooves a whirling motion, thereby thoroughly intermixing the air with the fuel. The apertures 31 enable pressures in opposed mixing grooves to be substantially equalized, thereby obtaining perfect combustion. The flames of burning material pass up between. directing ribs 43 of chimney 5 which acts to elongate the flames, thereby securing complete combustion while protecting the flames from cross-currents of air. The material of the chimney also holds heat, thereby aiding the combustion. Heat is likewise conducted through the mixing blocks, thereby serving to preheat the fuel mixture in the mixing grooves.
By merely manipulating the handle 25 of the air supply regulating slide, the relative percentages of fuel and air may be varied, thereby varying the intensity of the resulting flame.
As many changes could be made in the above construction and many apparently widely different embodiments of this invenbe interpreted as illustrative and not in a limiting sense.
What is claimed is 1. A burner for gaseous fuel comprising adjacent members having opposed mixing grooves therein, a dividing plate positioned between said members for separating said opposed mixing grooves, and a fuel supply pipe positioned below said mixing grooves and said dividing plate, said fuel supply pipe having jets extending upwardly therefrom to said dividing plate, said dividing plate serving to split the streams of fuel delivered by said jets into half streams, each of which half streams passes up a respective one of said mixing grooves.
