My invention relates more particularly to burners for utilizing heavy` oil, such as crude oil, as fuel, and is designed to thoroughly atomize and vaporize the fuel oil and intimately mix Ait With steam and air priorv to .In the accompanying drawing, VFigure 1 is alongitudinal axialsection throughpa burner embodying my invention; and-F ig.

2a front view ofthe nozzle or outlet end thereof.

Referring to the dravving,'itY W'ill'be seen that the specific construction of my invention chosen for illustration thereof comprises .a doubly conical housing 3 formed of tWo conical members 4, l5, bolted together attheir flanged bases and respectively provided. at

their reduced ends with an interiorly threaded nipple 6 and an exteriorly threaded nipple 7. A Washer 9 is interposed between-the flanges to secure ya tightV joint. A T 10.is connected to the interiorly threaded nipple 6 by a reducing union 11.' yThe opposite end of the 'i'y 10 fromv that which receives the reducing union receives a reducer 12 Which is connected to av second smallerT 13by a pipe section 14. The; side nipple'15 ofthe largerl T10 receives a reducer 16 towvhich is connected a'pipe'l for supplying fuel oil' yto the T. The side nipple 1,8 of the smaller T l3is connected to a pipe 19 for vsupplying steam; under pressure.v j t f v A 'tapering pipe -or nozzle 2O is secured at one end Withinthered-ucer12 and. extends 4through the T 1() and opens into the housing 3 s'o that steam entering the pipe 19 Will discharge into the housing. The external diameter of the tapered nozzle 2O is such that an annular passage 21 surrounds it Within the reducer 11 so that the fuel oil entering at` pipe 17 may pass around the nozzle l2() and vinto the housing 3. Y

yThe outlet nipple 7 of the housing is interiorly and exteriorly threaded, the interior thread receiving a nozzle 21a, the bore of Which is tapered as shown and Which projects beyond the end of the casting 5. The outer thread of the nipple 7 rec-eives ay cap 22 which is perforated at 23 by a number of small jet holes (see Figs. 1 and 2). A larger hole 24 is formed at the center of the cap and is flared or tapered at its inlet end as at 25. An air supply pipe or jet 26 extends substantially through the entire burner, terminating just short of and in axial alignmenu-with the hole 2411i thefcap'. At `its. opposite end the air pipe 26'extends'through the endof the'l' 13, Preferably it is `formed 'with or connected -to anV enlargement 28 which extendsthrough a plugf29 screwed into the "le",Y 13 and said enlargement termij,

nates in ay chamber 3 0 having means for reguf lating the supply.k of air thereto. Y Fory this purpose I have illustrated an ordinary Bunsen burner air. control with the usual rotary regulating means 31, a plug 32a/ith.,` a permanently open vhole 33 vbeing inserted-in the center of the regulating airadmission plate.'

Other means for regulating the supplyof air'. may be employed. ry Within the chamber 3 formed by the conical castings 4, 5, is mounted a deliecting cone 34 the inner or smallend 35 vofrvvhich closely surrounds and maybev attached to thev .air pipe at a point adjacent the end ofthe steam -nozzle 20. The louter or larger end-ofthe fcone 34 is securedat 36 to the, conical member 5. Passageways forrthe steamand air` between the cones 34 and 5 are provided by means of cutout portions 37in the edge of cone 34, so that the mixture of vaporsy en'- tering the chamber 3 mayl pass to the chamber formedV by the cones 34 and .5,Y

Steamentering the pipe 19 preheats the air.

in the pipe 26 and also the oil entering the `T 10. At the end ofthe'nozzle 2O the stream is discharged into theannularchamber in the i' housing 3, Where it impinges upon the cone 34, highly heating thesame-and mixes With `the oil entering said chamber fromthe .T 10.

The oil, Which-has'been somewhat preheated as above described, is drawn intothe chamber of the housing 3 and mixes with the steam therein and imp inges upon the cone 34. ltfis highly heated and vaporized thereby and the" mixture of steam and o-il vapors` formed :passes onward and enters the chamber formed by the cones 5, 34. The'mixture of steamand o il vapor as it lenters about the base of cone 34 is given a whirling and eddyingv motion so that more complete vmixing takes place in said'chamber and the mixture under `pressure passes out throughfthe annular space between the nozzle 21 and tlieai-r pipe 26 into the distributing cap 22. The rapidly moving mix.- ture of steam and oil vaporentrains or aspirates air through the pipe 26, the amount of Which is controlled by the means heretofore described. The mixture of steam, oil, vaporl 'and-air not only escapes through the openingv 24 huttlroligh tlie lsiirrolindilig mller perfora-tions whereby it is thoroughly mixedA With the additional air'necessary to support combustion. 'M p Obviously the perforated cap 22 may be omitted or other forins of burner terminals submit-ted therefor. Many other changes,

particularly in the nilis' -for supplyingoil and Isteam;will*suggest themselves to those tlilled in this'art. l 'Ic'limzfg'ttvigah bul-,lamme met@ ena and aninleitV opening at tllefther, ailfair supply pipe extehdirlgtlrough' hehousing land into the ltlt ,no'zizele fa conical `partition tin the hllsipg silrroun in'g'thela'irl pipe,"the smaller Y ''idhf the partitonfbeing directed toward illg-aeam'abuttheair inletlplp'e and direct- VLouter face of theconical partition thereby Y heating and vaporizing the oil.
