FLUID FUEL BURNER Filed Jan. 10, 1944 lowing described parts.

Patented Sept. 19, 1944 UNITED STATES PATENT OFFICE FLUID FUEL BURNER. Elmer J. mu, Kansas City, Mo. Application January 10, 1944, Serial No. 517,666

1 Claim.

My invention relates to improvements in fluid fuel burners. It is particularly well adapted for burning liquid fuel, such as heavy hydrocarbon oils, petroleum, or refuse oils.

One object of my invention is the provision of a novel burner oi the kind described, which will completely atomize and oxydize the fuel, and which will eliminate the deposit carbon, soot or oil drippings.

A further object of my invention is the provision of novel means by which the oxydizing agent or agents used are intermingled with the fuel.

Another object of my invention is the provision of a burner oi the kind described, which is simple, cheap to construct, durable, not likely to get out of order, which can be easily made and operated by a person who is not a skilled mechanic, and which is efllcient in its operation.

the center of the disk ll.

12 are clrcumferentially angled in a like direc- The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawing, which is illustrative of a preferred form of my invention,

Fig. l is a longitudinal side view, shown partly in vertical sectionand partly in elevation, of my improved burner. Y

Fig. 2 is a side elevation, partly broken away of the burner shown in Fig. 1.

Fig. 3 is a reduced side elevation of the burner, shown in Figs. 1 and 2, operatively mounted in an air conducting casing, shown in vertical section and operatively supported in the wall of a structure with which the burner is to be used, a portion of said structure being shown in vertical section.

Fig. 4 is an enlarged end view of one of the radially slotted partitions of the burner.

Fig. 5 is an edge view of what is shown in Fig. 4. I

Fig. 6 is an end view, enlarged, or the partition which is intermediate of the two slotted partitions.

Similar characters of reference designate similar parts in the difierent views.

The burner shown illustrated in the drawing as one form of my invention, comprises the foldesignates a steam chamber consisting of a horizontal tube 2, to the ends of which are secured respectively end members 3 and 4.

Centrally secured in the end member 3 is a tube 5, .which is connected with a fuel fluid supply source, not shown, as an oil tank. A fluid .discharge tube 8, having its intake end. threaded,

is fixed in the inner end of the tube 5, to which it is held by a nut 1. The other end of the tube with a source of steam supply under pressure, as

a steam boiler, not shown.

Attached at one end to the outer side of the end disk or member 4 is a horizontal tube l0 havin secured to its other end a disk ll, shown enlarged in Fig. 4, and which is provided therethrough with a series of radial slots l2, evenly spaced, and which extend inwardly from the periphery of the disk to points equally spaced from The sides of the slots tion from a right angle. The chamber between the end member 4 and the slotted disk ll comprises a mixing chamber, designated by I3, in which oil discharged from the tube 6 mixes with the steam entering the chamber l3 from'the hole 8.

Attached to the side of the disk ll opposite to the side next the chamber l3 is one end of a longitudinal horizontal tube M, the other end of which is attached to one side of a partition disk 15 having through it a central hole Hi. The

space between the disks II and I5 is designated chamber ll.

Attached to the other side of the disk i5 is one end of a longitudinal horizontal tube l8 the other end of which is attached to one side of a transverse slotted disk l9, which corresponds in structure and function to the disk H. The space between the disk l5 and disk i9 is designated chamber 20.

Attached to the other side of the slotted disk I9 is one end of a longitudinal tube 2i, having its other end of less diameter, and in which is fitted one end of a discharge tube 22. Th space in the tube 2| between the disk l9 and the discharge tube 22 is designated chamber 23.

Referring to Fig. 3, 24 designates ahorizontal tube having at one end a head 25 and at its other end a head 26. Fastened toone side of the tube 24 is an air supply tube 21 interiorly communicating with the-tube 24 and connected to a source of air supply, preferably under pressure, as an air pump, not shown. The head 26 has a central hole 28 in' which is secured one end of a horizontal tube 29, which, as shotn, is secured in a hole in one side of a wall 30, which may be a part of a fire box of a steam boiler, not shown. The head 25 has a central hole therethrough in which is secured to the right of the steam inlet 9, the periphery of the tube 2. The space in the tubes 24 and 29 is designated chamber 2. The

portion of the burner. at the right of the tube 2, extends centrally into the chamber ii, the discharge tip of the discharge tube 22 terminating adjacent to the discharge end of the air tube 29.

In operation, steam under high pressure is ad-' mitted into the steam chamber I through the inlet tube 9, and fluid fuel, as oil, is supplied to the tubes and 8, and the oil discharged from the tube 6 mixes with the steam and is discharged therewith through the hole ,8 into the mixing chamber l3.

From the mixing chamber 13, the mixed oil and steam passes through the bevelled slots l2 of the disk ll into the chamber H, in separate streams which due to the pressure of the steam whirl to the right, looking forwardly, the oil being sprayed, so that a fine .mist passes through the hole IS, in the partition disk |5,into the chamber 20, from which the mist passes through the slots I2 of the disk l9, where the streams of mist are further whirled in the chamber 23 with a force that atomizes the oil, and the mixture enters the discharge tube in the form of highly heated vapor, which, when lighted, is oxidized by the air under .pressure passing out of the chamber 3|, and burns fiercely in the fire box, or other place into which the burning mixture is discharged.

When the mixture is burned, there is no deposit of carbon soot or drops of oil, as the latter is completely burned.

When the burner is made, if desired, the outer ends of the slots l2 of the disks H and is may be closed. as by spot welding, but in the set up shown, this need not be done, due to the fact that air in the chamber 3| will be mixed with the steam and oil mixture passing into the chamber.3| from the slots I 2, and will assist in the oxidation of the oil.

In order that the steam and oil mixture shall be driven with strong force through the slots l2 of the disks II and is, so as to be given violent whirls, the cross sectional area of the passage through the discharge tube 221, and that of the hole H5 in the disk l5, should be at least as great as the combined cross sectional area of the slots l2 in either one of the slotted disks II and Hi, to prevent back pressure. Due to this construction, the oily vapor issuing from the discharge tube 22 will have a maximum of atomization, and will be r quickly oxidized by the air with which it mixes, with the use of a minimum amount of steam, and with the elimination of carbon, soot or oil deposits.

' As shown, the main body or casing of the burner comprising the tubes 2, I0, I 4, l8, 2'! and 22 are separate pieces, as are the end members 3 and-4 and the disks ll, I5 and I9, these parts being fastened together. as by spot welding. By means of this construction, the burner can be easily made by an unskilled person.

The tubes 2, IO, M, I8 and 22 may be pipe sdctions cut from lengths of piping of proper diameters and in desired lengths, and the tube N may be a pipe section comprising a usual reduc ing connector. The end members 3 and 4 and i the disks ll, l5 and I9 may be easily cut from fiat metal of desired thickness'into' the desired form. The beveled slots l2 in the disks II and It! may be easily cut with a hack saw from their peripheries inwardly into the beveled form, and the central holes in the end members 3 and l and the hole l6 in the disk l5 made with a hand drill.

If desired, however, the six pipe sections 2, I0, I 4, l8 and 22, and the end members 3 and 4 and disks ll, l5 and I9, may be made originally in any well known manner, as by molding or die casting to form an integral body.

Many modifications of my invention, within the scope of the appended claim, may be made without departing from the spirit of my invention.

What I claim is:

Aiiuid fuel burner of the kind described comprising a longitudinal tubular casing having a closed rear end and at its front end a discharge nozzle, two transverse partitions in and across said casing at the rear of said nozzle, one forward of the other, and each having therethrough radial slots arranged in a circle and extending forwardly and laterally with their sides angled in a like direction relative to the circumference of the circle, a partition across said casing intermediate of said slotted partitions and. having a central hole therethrough, the cross sectional area of the inside of said nozzle and that of said hole each being at least approximately as great as the sum of the cross sectional areas of the slots of either of said slotted partitions, a partition across said casing at the rear of said rear slotted partition and having a central opening, said casing having at the rear of the last named partition an inlet for fluid under pressure,

and piping for conveying fluid fuel having its front end axially alined with and discharging through said central opening and spaced from the perimeter thereof.
