FLUID-FUEL BURNER.

Specification of Letters Patent- Patented A11 3, 1915.

Application filed October 28, 1914. Serial No. 868,958.

To all whom it may concern:

Be it known that I, HANS T. PETERSEN, citizen of the United States, residing at Seattle, in the county of King and State of VTashington, have invented a certain new and useful Improvement in Fluid-Fuel Burners, of which the following is a specification.

My invention relates to improvements in burners for burning fluid fuel in boiler furnaces, and in the fire-boxes of cooking stoves and heating stoves, and the object of my invention is to provide a burner that shall be simple in its plan of construction, reliable and eflicient in operation and that shall be adapted to burn both high and low grades of fluid fuel, as, for instance, gasoline, kerosene oil and crude petroleum as well as different gases. I attain such objects by devices illustrated in the accompanying drawings wherein Figure 1 is a view in longitudinal midsection of a burner embodying my inven tion; Fig. 2 is a view of the same in crosssection on broken line 00, w of Fig. 1; Fig. 3 is a view of the same, on a reduced scale, in cross-section on broken line y, y of Fig. 1, and Fig. 4 illustrates a modified form of a detail in longitudinal mid-section of the same.

Referring to the drawings, throughout which like reference numerals indicate like parts, a hollow cylindrically formed body portion 5, of cast metal, which is provided on its lower end portion with oppositely projecting bosses 6 and 7, respectively, has its interior hollow space divided by a partition 8 to form two chambers 9 and 10 a fluid fuel supply pipe 11 is disposed to screw into the boss 7 to communicate with the chamber 10 and a pipe 12, for steam or compressed air, is disposed to screw into the boss 6, through which pipe 12 steam or compressed air may be admitted into the chamber 9. The upper end wall of the chamber 9 is provided with a slotted opening 13 which extends crosswise in a plane parallel with and adjacent to the partition 8, through which a thin sheet of steam or compressed air may be emitted from the chamber 9 in a direction parallel with the axis of the body portion 5.

The chamber 10 extends upwardly for a slightly greater distance than the chamber 9 whereby the inner side of its upper end wall is higher than the outer side of the upper end wall of the chamber 9 and a thin slotted opening 14 is disposed to extend outwardly from the top of the chamber 10 in a horizontal plane that intersects the vertical plane of the slot 13, thus fluid fuel under pressure may flow from the chamber 10 through the slotted opening 11 in the form of a thin sheet-like'jet immediately to impinge upon the side of the sheet-like jet of compressed air or steam that may be flowing upwardly in a vertical direction from the slot 13 thus to mix with such compressed air or steam and be carried upward thereby in the form of a combustible mixture.

The upper and outer portion of the upper end wall of the chamber 10 is enlarged and formed to provide a screw-threaded socket 15. The upper part of the body portion 5 is provided with an external screw-thread and screwed thereon is a larger end of a reducer coupling 16 into whose smaller end is screwed the lower end of a pipe 17 upon whose upper end is screwed a burner tip 18 and concentrically disposed within the pipe 17 is a rod 19 the lower end of which is screwed into the screw-threaded socket 15, while upon its upper end is mounted a plurality of radially slotted disks 20 of such diameter as will cause their peripheries to engage with the inner surface of the pipe 17. The radial slots of each of adjacent ones of said disks 20 are disposed in a staggered relation with each other thus to serve as a baflle to mix more thoroughly the fluid fuel and the steam or air as such mixture flows toward the burner tip 18.

Fig. 3 illustrates more clearly by full lines and dotted lines the relative positions of the radial slots of adjacent ones of disks 20.

In Fig. 4 I have shown a projecting ridge 21 disposed on the exterior surface of the upper end wall of the chamber 9 adjacent to and parallel with the slot 13, which projecting ridge 21 may serve to deflect the fluid fuel as it issues in a sheet-like jet from the slotted opening 14:. Such ridge 21 may be advantageously employed when heavy low grade oil is used as a fuel but is unnecessary in cases where more volatile oils or gases are used as a fuel.

The operation of my burner is as follows: Fluid fuel is admitted into the chamber 10 through the pipe 11 from a valve-controlled source of supply not shown and air under pressure, or steam, is admitted into the chamber 9 through the pipe 12, the fluid fuel passing out of the chamber 10' through 17 and the radial slots of the disksQO and thence through and out of the burner tip 18 to-be ignited at-the point of combustion.

Qbviously, ,changes may be made inthe form, size and arrangement of the different p rt ro -a y i venti n hou departing from the spirit thereof. What Ielaimpis;
