BURNER FOR BAKE-OVENS.
Application filed March 3, 1919. Serial No. 280,312.
T0 at whom it may concern Be it known that l, Jaon B. MACDONALD, citizen of the United States, residing at Oakland in the county of Alameda and State of California, have invented certain new and useful Improvements in Burners for Bake-Ovens, of which the following is a specification.
This invention an improved burner particularly useful for rotary bake ovens.
The invention is illustrated in the accompanying drawing which forms a part of this specification and the appended claims.
Referring to the drawing:
Figure 1 is a cross section of an oven embodying my invention.
Fig. 2 is a perspective view of the burner.
Fig. 3 is a sectional view of the burner fuel valve.
Fig. at is a fragmentary view of the lower part of the burner assembly structure.
The burner includes an elongated gas generator 1 formed with downwardly curved arms 2 at its sides and with an intermediate longitudinal pocket 3, said generator being mounted above an elongated pan a on stand ards 5 extending through the ends of said pan and secured thereto by nuts 6 and 7 and screwing into embossments 8 in the bottom of pocket 3. Jets 9 and 10 extend downwardly and inwardly opposite each other from the lower extremities of generator arms 2. A fuel supply pipe 11 having extensions 12 and 13 is connected at the ends of said extensions to'the ends of the burner generator 1 above pocket 3 by means of couplings 1 1 and 15. A valve 16 is provided for controlling the supply of fuel to the burner. Said valve is formed with a central chamber 17, an inlet nipple 18 and inlet port 19 and an outlet nipple 20 and the outlet port 21, the inlet port 19 leading into and the outlet port 21 leading from said chamber 17. The valve is formed with an inlet port 22 which leads into the rearfrom a source of fuel such as oil connects w th valve nipple 18 and pipe 11 connects with valve nipple 20. A nipple 31 connects a pipe 32 with inlet 22, said pipe leading from a water supply (not shown). A perforated pipe 33 extends along the top of the chamber 1 for sprinkling water thereon and down into pan 41-.
The burner is particularly useful for supplying a moist heat to a rotary bake oven 36 which forms the subject matter of my copending application for patent Serial No. 280,318, filed March 3, 1919.
In the bottom wall 37 of said oven is formed a trough 38 extending longitudinally of the oven adapted to receive the burner which may be slid into the trough through an opening 39 at one end of the oven casing, said opening being normally closed by a door 10. Above the burner is journaled the baking reel on which are pivotally suspended shelves 4:6 for supporting baking pans 47.
The fuel is a mixture of oil and water which on entering the generator 1 through extensions 12 and 13, the water tends to fall out and settle in the pocket 3. The pocket being directly over the flame of the jets 9 and 10 is heated intensely which causes the water in said pocket to vaporize into steam, thus providing a moist fuel which is burned at the jets and a moist heat generated thereby. 'Water is sprinkled from the perforated pipe 33 on top of the burner generator and flows down around the hot sides of said generator and is vaporized into steam, thus moistening the heat of radiation given off by the burner. Any water from the outer surface of the chamber drops into the pan 4:.
Doors are hinged to the trough 30 and are normally kept closed by catches 51. Vents 52 are provided in said doors for admitting air into the trough 38 to the burner, said vents being controlled by pivoted dampers 53. The generator is provided with an opening at one end of the pocket-3 which is closed by a cap 54:.
An overflow spout leads from the pan 1 and is coupled by coupling 61 to an outlet pipe 62 through which the water flows from the pan to enable circulation of the water through said pan.
The mixing of the water with the oil eliminates carbon and reduces gaseous fumes to a minimum.
Circulation of water from end of pipe 33 through pan 4 and out through outlet pipe 61 keeps the burner cool and carries off all gas fumes. I Having described my invention, I claim:
1. A burner comprising a generating chamber having downwardly curved and hollow side portions, the lower edges of said side portions having a plurality of burner jets extending therefrom, said generating chamber having a liquid trap portion lying between said side portions and overlying the burner jets.
2. A burner comprising a generating chamber having downwardly and inwardly curved hollow side portions, and further having a liquid trap in the body portion thereof and between said side portions the lower edges of said side portions having a plurality of jets extending downwardly and inwardly therefrom and underlying said liquid trap. a
3. A burner comprising a generating chamber substantially of inverted crescent shape in cross section said chamber being provided with a longitudinal groove in its lower wall to form a liquid trap, and a plurality of burner jets extending from the lower edges of said chamber and underly ing the said trap.
4. A burner comprising a generating chamber having downwardly and inwardly curved hollow side portions, and further having a liquid trap in the body portion thereof and between said side portions, the lower edges of said side portions having a plurality of jets extending downwardly and inwardly therefrom and underlying said liquid trap, and a trough-like drip pan disposed under said chamber, and means for supporting and maintaining said chamber and drip pan in relative position.
5. A burner comprising a generator chamber having downwardly sloping sides and burner jets projecting from said sides inwardly toward each other, means for supplying fuel to said chamber, means for spraying water over said chamber, whereby the water will flow over the sides of the chamber, and a drip pan arranged under said chamber and secured thereto.
6. A burner comprising a generating chamber having downwardly and inwardly curved side portions, means for supplying fuel to the chamber, means for spraying water on top of the chamber, whereby the water will flow down the sides thereof, and a plnrality of burner jets extending downwardly and inwardly from the lower edges of said curved side portions of the chamber, where by the jets are protected from said water.
In testimony whereof I afl ix my signature.
JACK B. MACDONALD.
