l OILAND GAS B-URNER.
srncrnohnon forming part of vTo all whom it may concern.-
Be it known that I, Louis SCHUTTE, of Philadelphia,-in thc county of Philadelphia and State of Pennsylvania, have invented certain 5 Improvements'in Oil and Gas Burncrs,of which the following is a specification. a
My invention has reference, first, to a burner adapted for, the use of 1iquid-fnel--su'ch'as-hydrocarbon oil-and, second, to a burner having in addition to the oil-burning devicessupplenlental parts, by which it is alsoadapted to burn gas when desire My inventionv relates to that class of burners by which the liquid fuel is atomized and 1 combined with atmospheric air. The most important requirement in connection with such burners is that the liquid fuel shall be finely divided and'intimately combined with the air in constant proportions. Many burn- 0 ers making use of steam and air jets to effect the mechanical separation of the fuel and its combination with air have been devised; but in practice it has been found that in order to secure a satisfactory action in other respects 2 5 it was necessary to reduce their openings and passages to such minute proportions that it was impossible to maintain a proper adjustment and prevent stoppages and irregularities in action. Now the principal aims of my invnecessity for the small openings, to insure the perfect atomization of the fuel and its intimate admixture with the air, and to secure changes in the amount of fuel consumed, as occasion may re 3 5 quire,without adjusting any of the parts of the burner; To this end I make use of a burner in which the stream of oil in its course to the point of delivery is first given a rotary motion and then delivered through a round un- 0 obstructed opening of large sizein such manner that it issues in the form of a hollow cone and in the condition of a fine spray or mist. This cx 'ianding jet is projected centrally into a snrronndingcolumn of air and mingles there- 5 with.
In the accompanying drawings, Figure 1 represents a longitudinal axial section through an oil-burner constructed on my plan, Fig. 2 is a similar section of the burner modified,
to adapt it for the use of either oil or gas, as
I Fig. 3 is a diagram occasion may require.
Ifetters Patent No. 391,865, dated October so, 1888-. Application filed November 5, 1887. Serial No. 254,402, (No model.)
showing the connection of the .air and oil pressure apparatuswith the burner.
nicates through an intermediate chamber with a tubnlarspindle, c, which is screwedinto the body of the burner,-a'ndwhich extends for-- ward centrally through the air-passage to the a forward end, where it is provided with a delivery-nozzle,d,screwed therein. This nozzle, which is provided with a central delivery-orilice, contains a fixed spindle, e, having on its exterior a series of spiral wings or blades adapted to impart to the outflowing oil a spiral or rotary motion around the line of its trajectory. The spindle is preferably formed upon a perforated plug, d,'screwed into the rear end of the nozzle, and terminating at its forward end within the "nozzle somewhat in rear of the delivery-orificc as shown in Fig. 1, this construction allowing an uninterrupted circular passage around the forward end of the spindle at the points where the oil issues from the nozzle.
In order to secure a proper-atomization of the passage of air the oil and to prevent the choking of the delivery-orifice, it is of importance that the outlet or deli veryorificeshall be of circular form and without obstruction of any kind therein;
hence the importance of the fact that my spindle e terminates within the burner at a distance from the point at which the oil is released. The oil being compelled to act against the spiral blades receivesa rapid rotation,and then issuing with this rotation as a solid unbroken stream at the center it is effectually scattered or atomized by the centrifugal force developed.
In order that the airrcurrent may also receive the rotary motion in issuing through .the passage at around the air-jet, I locate within the passagea spiral blades or ribs 9, preferably formed on the outside of the spindle c, as shown in the drawings.
it issues in a tubular column around the out side of the oil jet, thejets impinging one upon 6o delivered through the burner.
In order that the air-jet delivered through the nozzlca may induce the inward flow of an additional volume of air, I apply around the nozzle a a second and larger nozzle, 0, extending forward beyond the other nozzles,as shown. This is so arranged as to leave an annular inlet between it and the exterior of the nozzle a.
In order to properly control the admission of the air through the nozzle 0, I' provide the same with a rotary ring, D, having a'series of openings adapted to register with corresponding openings in the base of the nozzle 0. This ring constitutes an ordinary valve or register of familiar form. V t
In operating the burner,oil is delivered under pressure through the neck b,spindle c,and nozzle (1, the oil issuing from the latter in a forward direction in a finely-divided or atomized condition, the jet expanding in the direction of delivery in the form of a hotlow cone, as represented in the drawings. Air is at the same delivered through the nozzle a, whence the other,as indicated in the drawings,in such manner that a thorough and uniform admixture of the air and oil is effected. The outflowing currents of air and oil induce an additional current of air through the .nozzle O,this supplemental supply of air commingling with the other as it issues from the nozzle 0. Suitable valves will be provided for controlling the delivery of air through the nozzle a, and a valve, E, is provided for controlling the oildelivery. It is to be understood that the external cone or nozzlc,C, is not a necessary feature of the burnerand that it may be omitted, if desired.
When the'burncr is to be adapted for use with gas or with a supplemental supply of air, I adopt the construction shown in Fig. 2. As here shown, the nozzle 0 is closed or joined at its base to the nozzle a and provided on one side with a throat or inlet, is, through which either gas or air may be admitted.
Toprovidc fora wide range in the capacity of the apparatus,I proposcto provide the oil-supply under suitable pressure and means of ad mitting the oil to the burner under more or less pressure, as demanded. For example, if the minimum pressure at which a proper atomizationtakes place is thirty pounds per square i neh the volume of pressure at this point would represent the ininimum capacity of the instru ment. If now the pressure of the oil be increased, the capacity of the burner will be correspondingly increased. Any increase in the delivery of oil is to be accompanied by a corresponding increase in the volume of air This may be accomplished by a regulation of the a'irrsupply or otherwise, Instead of forcing the oil or. gas through the burner, good results may be attained in some cases by applying a sue-s J oil-spray and with properly-proportioned surrou nding tubes, theoil-spraywill forlnthe actuating-jet of an air-injector, andrby this meansdraw in and furnish its ownair-supply ,for combustion. This is a particularly desirable feature in starting a fire when-the natural draft may not be as high as after the fire is started, or iii-applying the burner to locomotives where the air-blast is at disposal when the locomotive is in motion.
I am aware that it has been proposed'to deliver oil through a conical nozzle having shallow grooves on its internal surface, and that ithas been proposed to provide the air-passages of oil-burners with inclined spiral ribs. I believe myself to be the first, however, to provide an oil-delivery nozzle from which the oil is projected in a free condition to the point of combustion with an 1 unobstructed deliveryopcning and ribs or passages by which the oil is first given a rotary motion and thereafter delivered in a solid stream through said openmg.
\Vhat I claim isr I. In an oil-burner, a. final oil-deliverynozzle provided with a round unobstructed .delivery-orifice, and with internal spiral blades terminating at a distance from the deliveryorifice, whereby the oil is first given a rotary motion and thereafter delivered in a solid jet throughthe orifice, to the end that it may be atomized by centrifugal force.
2. In an oil-burner, the combination of an air-delivery nozzle and a central and final oildelivery nozzle, the latter provided with a round unobstructed oil-delivery orifice andthe orifice as a rotating solid stream, atomized by centrifugal force, and delivered in its atomized condition centrally into the column of ai r [10 wing th rough the surrounding air-nozzle.
In an oil-burner, the combination of the central and final oildelivery'nozzle having the round unobstructed delivery-orifice, and
the internal spiral blades terminating in rear of said orifice, the air-delivery nozzle a, surrounding the first-named nozzle and terminating in rear of the oil-delivery, and an external lid nozzle, A, surrounding and extended slightly beyond the nozzle a, as shown. In testimony whercofI hereuntosct my hand,
this 3d day of November, 1887, in the presence of two attesting witnesses.
