BURNER.

' Applicationfiled February 21, 1924. Serial No. 834,336.

' To all whom it may concern.

. ducting nozzle therefor to increase'the com- Be it known that I, PAUL W. Korrs, a citizen of the United States, residing at Proctor, in the county of St. Louis and State of Minnesota, have invented new and useful Improvements in Burners, of which the following is a specification.

' My present invention has reference to a liquid fuel burner, and my object is to simplify and improve such class of devices and to produce a burner in which the fuelis heated. in its passage through the conin sugar mills and that may employ molasses as the combustible agent, the same being heated in its passage through the burner nozzle for the atomlzation or the breaking up of the particles of fuel and having direqt'ed thereagainst at'its outlet through the nozzle a fine spray of steam which is criss-crossed to insure a better atomization of the fuel for directing the said fuel from the nozzle into the fire box, the burner, of course, being susce tible for use in connection with other fue s, such as oil or the like.

With the foregoin broadly stated objects in view and others w ich will present themselves as the nature of the invention is better understood, reference is to be had to the lar drawings which accompany and whichform part of this application.

In the draw1ngs:- e v Figure 1 is a lan view of a burner in accordance with t is invention.

Figure 2 is an approximately central vertical longitudinal section therethrough.

Figure 3. is. a perspective view of the nozzle.

Figure 4 isa central transverse sectional view through the improvement.

Figure 5 is a perspective view of the nose piece employed. I r

.The heater chamber of the improvement comprises a casting l-havinfi a' central tubupassage 2 .therethroug The 'castmg, has outstanding apertured ugs 3 designed to be secured on a support. The apertured lugs permit the' burner to be properly sup-,

ported and adjusted with respect to the fire,

box in, which the burner is arran ed. The ends of the chamber 1 are forme with interior threads 4. As both ends of the chamber 1 -are similarly constructed, it will be apparent that the nozzle and nose member, hereinafter to be described may be attached to either of said ends.

-One vside of the casting comprising the chamber 1 has a threaded opening there-' through, and screwed in this ening there is a pipe connected to a suite le source of steam supply, and whereby steam is let into the chamber. In this connection,'I desire to state that in lieu of steam, other vapor-- ized fluids, preferably of a combustible nature, may be employed.

Screwed in, one of the threaded. ends 4 of the chamber 1 there is the thickened and exteriorly threaded portion f the nozzle 7. The nozzle 7, and its portion 6, are round in cross section. portion 6 of the nozzle and designed to contact with one end of the chamber 1 there is a jamb nut 7'. By this arrangement, the nozzle may be ad'ustably received in the chamber 1. Outwar of the threaded enlarged portion 6 of the nozzle 7, there is a further enlargement, indicated by the numeral 8, provided with interior threads for engagement with api e member 9 through which the liquid gravity into the burner.

The head of the nozzle is indicated, for distinction, by the numeral 10. The head is provided by thickening the body of the nozzle, and the outer end of the head is cone- Screwed on the threaded el is fed by shaped, as indicated by the numeral 11.

The head, is provided with any desired number of annular depressions 12 forming annular. shoulders therebetween; These shoulders are provided with lon itudinal aligning channels 12. The conica end 11- is formed with spaced longitudinal channels 11' theinner walls of which are arranged angularly at approximately 20 degrees.

Screwed in-t e outer or free end of the chamber 1 there is the reduced endv rtion of a nose piece 13. o The nosepiece 1 has a rounded bore to receive the cross sectionally rounded head '10 ofthe nozzle. therein, the

said bore. being inwardly rounded to provide a conical portion'14 that is disposed adjacent tothe conical end 11 of the head 10. The nose piece has an inwardly flared mouth 15 which communicates with its bore v and with the bore of the nozzle. Incident to the threaded engagement of the .nose piece ing, of course, loosened to permit of such adjustment.

Steam or any other suitable heated va-' porized. agent is let in the chamber 1 through the pipe 5. The steam surrounding, the nozzle effectively heats the same, so that the li uid or semi-liquid fuel which is directed y gravity through the nozzle willbe heated in its passage therethrough. This; tendsvto atomize such fuel and increase the] combustibility thereof. The steam finds an-outlet between the bore 14. of the nose piece 13 and the head 10 of the nozzle. The outlet as previously inferred, may be-restricted or enlarged- The steam, before reachin the outlet, will be directed throu h the c nnels 12 into the grooves 12 an abutting with the walls thereof will be retarded, and 3 particles of dirt will be prevented from passing into the flared mouth of the nose piece and this serves toimpart a cries-cross action to the steam. The steam then passes through the channels 11 as well as around the, conical end of the head .10 so that the same will be'forcibly injected into the fuel passing through the nozzle to thoroughly mix therewith, and likewise to direct the fuel through the flared mouth 15 of'the-nose piece, causing the same to be forcibly ejected therethroug in a copious spray in all directions into the fire box for filling the entire fire box.

From the foregoing descri tion, when takenin connection with the drawings, it

will be noted that I have produced a simple burner for liquid fuels which'may becheaply manufactured and readily installed. The nose piece may be arranged on either end of the casing 1, and all of the parts' constituting the improvement are interchangeable so that any damaged parts may;

be readily replaced. I wish to state, however, that I am not to be restricted to the precise structural features herein set forth but may make such changes therefrom as fall within the scope of what I claim,

Having described the claim A liquid fuel burn'er, com rising a body having a tubular bore, thre ed at the ends thereof, and having a central steam inlet, a liquid fuel conducting nozzle having a thickened; portion which is threaded and which is screwed in one end of the body, a

jamb nut screwed in the said thickened portion of-thenozzle and contacting the end-of the body through which the nozzle enters,

invention, I

said nozzle having a headed end, whose outer portion is cone-shaped, said head hav-.

ing spaced circumferential grooves and spaced longitudinal passages for intersecting the circumferential grooves, and the cone-shaped head of the nozzle having passages aligning with the first mentioned passages but which last'mentioned passages are struck at angles of approximately 25 de-' grees, and a nose iece screwed in the second end of the b0 y and having a bore terminating in a conical end to'receive the head of the nozzle and the conical end thereof therein, and said nose piece having an inwardly flared month which communicates with its bore and with'the bore of the nozzle; g
