My invention relatest-o hydrocarbon burners.;or.,injeotorasuch as y, are employedy for buigningfmincral oils or theproducts of mineral oi'lsiin metallurgical furnaces.

My inventionwfurther,relates to that class of burn ers by which the hydrocarbons or their products-are mingledy Witlfair or steam prior to'theirintroductionin the form of flame into a metallurgical furnace. l

My invention alsofrelates to the combination withsuch hydrocarbon-burners of a su pporting-standfor saidvvburners.I y 1 In the accompanying drawings, which illustrate my il'lvention,similarletters of reference indicate,lilz'evpartsgi A Figureffl gisanelevation of my improved hydrocarbon@urnerr.,Fig isa longitudinal vertical,section.l Fig' f-is 4a transversesec-v tion on .th'elinex x ofw-Fig.2.l Fig. 4 is an end viewofxt'henozzle. z.F-igy `,is an elevation of the .supporting-,stand,fonthe.nozzle, the oilduct being shown in;,ve rtcal section.

tion D and through 'theconical end portion D', which is preferably of refractorymaterial. The cylindrical portion D is tapped at E to receive the screw-.thread on the conical part D', and the body portion D is tapped at Fto receive the screw-thread G on the cylindrical outer shell I-I. The shell H fits over the part D, and is provided Iwith the conicall end H', of refractory material, which is'connected to the shell Hin the manner shown in jects slightly beyond the conical portion H. vI have dscribedthe part D and the part H as connected to thepart D and shell H by 5o means of screw-threads. If desired, the part D and the shell II may bel made of refractory HYDROCARBOfyN-BEURNER.

I material 'and continued forward to form the parts 'D' and I-I.

The shell II is bored in such a' manner that a scmicircular duct C is provided between' it and the part D and continued in `an upward direction through the conical end II of the burner to form an hpen ,ing in the shape' of a section of a ring, as

shown in Figs. 2 and 4. I is a two-way valve portion A. and duct C.

J is a duct, which communicates with the located in theibody duct B and with the duct C when the valve' I has its position at ninety degrees from that shown in the drawings, which maybe accomplished by means of the handle K,the object arrangement is to divert the air or steam'normally passing through the duct .I and B, for. the purpose of may have gathered therein. v

Referring to Fig. 5, L represents al standard, such as I employ for supporting my i'mproved nozzle4 when the same is used in. connection with a metallurgical furnace.

In practice thest-andard is placed in such a position as, regards vthe furnace that the end of the nozzle shall be from three to'four inches from the port-opening of the furnace.

The standard L is provided with the two supports M, which carry the spindle N.V The.A spindle N is arranged to have a vertical nio-Y 'tion and also to turn in the supports-M for ,tho

purpose of 'carryingthe nozzle or burner bin Y ahorizontally-circulardirection fromt liodv of the furnace when not in useQvQT,

plish these motions,;I provide the stiutli'iig`-l boxes O and O in the supports M.

' .To effect the vertical movement of the spin'f' dleN, I provide the'wheel P, upon which iS'v the pinion R, which latter gears with the cular rack S .on vthe spind1e T representsl a Apipe communicating withl the reservoir containing the liquid fuel, which it is desired to use with the apparatus. T is asimilar pipe communicating with a supply of steam or air. U and U are valves which respectively control these two pipes.

'The' spindle shown at V, the upper of which communicates with thepipeW and the duct B of the burner or nozzle A,and'thelowerof which communi- N is provided with ducts,a's

roo

cates with the pipe W and the ducts C and C of the nozzle A.

Y and Y. are valves, which respectively control the supply of oil and steam or air to 5 the nozzle. l l

' I carrying niy im proved invention into ef- -inay use any of the hydrocarbon oils'or their. products-such=' as petroleum, naphtha,

or anyof the residuums derived from the disrq tillation of petroleum. These oils are deliv-i y eredto the burner through the vipes T YV and duct B. Through `the pipes T VWfand ducts l`C and C', I may supply steam or air. If steam is employed, it should have a pressure of 'at l5 -least seventy,(70) pounds to the square inch but, preferably, should be superheated sof vto prevent condensation.

4 ln place of using steam,particularly whe hi'gh temperatures are desired,.I may use com 39 pressed air of from eighttoten pounds pressnrc.

The valves Y and Y' are employed in my device'for the purpose of regulating the lsupply of iliquid'fuel and steam or air, as desired.

' 25 In practice I- have found the best'results vfrom my'improved burner when the liquid fuel is of uniform consistency and-allowed to tlow4 through the nozzle by its own weight, y aided by thev injector action of theenteri'ng '3o-steam or compressed air.

Ihave described myv improved burner as iliade up'4 of several"A pieces. This arrangement is simply for convenience of con uc tion,'as it will be evident to any mechanic 3'5" that the device can be made in a single piece.

By the arrangement of ducts in myinjector I obtain' 'a solid column of liquid fuel and ay fan-shaped body of air or steam under the 'f column of liquid fuel, the result of which is "46' tojproduce a broad stream of diffused fuel,

which burns, when the supply o f the two materials is properly regulated,v without smoke,l

and thereby produces the bestresults obtain- Y ablewith burners of this description.

'-45 Having 'thus .described my invention, I

' claim- 1. Ahydrocarbon-burnercomprisinga body under the discharge-opening of the fuel-duct,` substantially as described.

2. A hydrocarbon-burner comprising a body portion having a centrally-located fuel-duct and an independent steamer air duct, the discharge-opening of which is located below in sliape is a section of a ring', substantially as described. l

3. A hydrocarbon-burner having independent ducts for fuel and steam or air, said steam or air ducts including the fuel-duct, and provided with a discharge-opening located under and behind the discharge-opening of the nel-duct, substantially as described. 4. Ahydrocarbon-burnercomprisiugabody ortion provided with a conical end and havng a centrally-located fuel-duct and au inlosing shell provided. with a conical end hav-` inga steam @or air duct, the discharge-opening of which is located below and behind the discharge-opening of the fuel-dnctand in a vertically-adj ustable and horizon tally-rotatable tubular spindle carried thereby, means consisting of a vrack of the spindle for adjustvalves for controlling the suppl'yof fuel and steam or-air tosaid burner, arranged as and in the manner set forth.4
