JOHN NICHOLSON, or HOUSTON, TEXAS.

HYDROCARBON-BURNER.

To all whom t may concern:

Be it known that I, JOHN NIcHoLsoN, a

citizen of the United` States, residing at Houston, inthe county of Harris and State of Texas, have invented certain new7 and useful Improvements in Hydrocarbon-Burn-` ers, of which the following is a specication.

This. invention relates to new and `useful improvements in Oa hydrocarbonburner.

The obj ect of the invention is to provide a burner of the character described which is especially designed for atomizing hydrocarbon, preparatory to burning the same, and is adapted for use in utilizing a low gravity oil or other heavy substances as fuel for locomotives, stationary boilers, kilns, heating furnaces and the like.

' With the above and other objects in view, the invention has particular relation to certain novel features of construction, arrangementV of parts, and use, an example of which is given in` this specification` and illustrated in the accompanyingdrawings, wherein:

Figures land 2, aretop and bottom views, respectively, showing the general-contour of the burner. n

Fig. 3, is a horizontal sectional view, taken through the oil chamber.

Fig. 4', is avertical, sectional view, showing both steam and Oil chambers, and

Figs. 5 and 6, show back and front views, respectively, of the burner.

VReferring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, the numeral 1, refers to an oil inlet pipe and the numeral 2, refers to a Steam inlet pipe said pipes being threaded into the burner and entering the fuel and steam chambers 3 and 4, respectively, of the burner 5. The steam and fuel chambers are separated by a transverse partition 6, and are relatively narrow at the base or outer end of the burner and gradually flare out toward the nozzle end thereof, and the upper wall of the fuel chamber, and likewise the lower wall of the steam chamber converge, gradually contracting said chambers to a point about midway the ends of the burner and said chambers then continue of uniform vertical dimensions to the nozzle end. Depending from the upper wall of the fuel chamber' is a transverse baffle 7 whose sides converge downwardly to an apex and beyond said baiile, toward the nozzle end of the burner,

the upper side of the partition; 6 has a plurality of longitudinal ribs 8, triangular in cross Section and gradually enlarging from their inner to their out'er ends. These ribs are spaced apart and terminate short of the burnernozzle. The nozzle end of the steam chamber is rounded ofi' at the point 9, and is provided with a transverse slit 10, through which the steam issues ina fanlike sheet, and the nozzle end of the upper wall of the fuel chamber has a slight downward curve forming the deilector l1.

The fuel chamber has two steam inlets 12, 12 at thebase thereof, through which the Vjets Of steam are admitted to said chamber at Vapproximately 4:5? angle. Oil is admitted into the fuel chamber through the'pipe l, and the steam jetsmingle withsaid oil, and break up and evenly distribute the same over the bottom of the said chamber, being deiiected towardthe bottom of said chamber, by the baffle 7, and beyond said baiiie, will be evenly divided by the ribs 8, passingbetween them and {iowing down over the roundedend of the steam chamber.V The` deflector ll causes a positive deflectionjof the fuel downwardly so as to prevent the pressure in the fuel chamber from blowing the fuel over the sheet of steamissuingfrom the slit `l(l,land thus forcing said fuel downwardly into said sheet of steam so that the steam and fuel will thoroughly mingle together,

Steam enters the steam chamber 4, through the steam pipe 2, under pressure, the pressure being sufficient to force the steam out through the slit l0, in a fanlike sheet and t0 catch up the fuel flowing down over the nozzle end of the steam chamber and thoroughly mingle with and vaporize the same.

What I claim is:

l A burner including a fuel chamber and a steam chamber, fuel and steam conduits entering said respective chambers, the nozzle end of the steam chamber being provided with a transverse slit, and the nozzle end of the fuel chamber having a plurality of longitudinal ribs therein spaced apart triangular in cross section andV enlarging from their inner to their Outer ends.

2. A burner including a fuel chamber and a steam chamber, fuel and steam conduits entering said respective chambers, the nozzle end of the steam chamber being provided with a transverse slit, the nozzle end. of the fuel chamber having a plurality of Copies of ythis patent may be obtained for longitudinal ribs therein spaced apart, and a transverse baiiie depending from the upper wall of the fuel chamber and located behind the said ribs',

3. A burner including a fuel chamber which flares toward its discharge end, the upper wall 0f Said chamber declining toward the lower wall, and the nozzle end thereof being downwardly curved, 'forming a deflector, longitudinal ribs spaced apart and arrangedin the discharge end of the cham ber and a transverse battle depending from the upper wall of the chamber and arranged behind said ribs. 4. A burner including a fuel chamber and -a steam chamber, separatedby a transverse partition, the nozzle end of the steam Ihamber 'being provided with a transverse slit, and the nozzle end of the upper wall of the fuel chamber forming a downwardly curved deliector to deflect 'the fuel issuing from said burner into the steam issuing fromsaid slit, a `bailledepending from the upper wall of the fuel chamber, and means arranged in the nozzle end thereof for 'sepa rating' the fuel issuing from the nozzle thereof;

A burner including a fuel chamber and a steam chamber separated by a transverse partition, the nozzle end of the steam chamber having a transverse slit through which steam issues, in a fanlike vsheet and the nozzle end of the fuel chamber being formed to direct the fuel issuing therefrom into the steam issuing from said slit, and a steam inlet arranged' at each side of the fuel chamber through which jets of steam are admitted into said chamber t0. mingle with the fuel therein,

6. A burner including` afuel chamber and a steam chamber separated by a transverse partition, the nozzle end of the steam chamber having a transverse slit through which steam issues, in a fanlike sheet and the noz zle end of the to direct the fuel v.issuing therefrom into the steam issuing from said slit, a steam `inlet arranged at each side of the -fuel chamber through which jets of' steam are admitted into said chamber to mingle with the fuel therein, and a transverse baille depending from the upper wall of the fuel chamber in front of said steam inlets.

7. A burner including a fuel chamber and a steam chamber separated by'atransverse partition, 'the nozzle end of the steam chamber having a transverse slit through which steam issues, lin a fanlijlre sheet, and the nozzle end of the fuel `chamber being formed to direct the fuel issuing therefrom into the steam issuing from said slit, a steam inlet arranged at each side of the fuel chamber through which jets of steam aread'mitted into said chamber to mingle with the fuel therein, and means arranged in l the nozzle end of the fuel chamber vforseparating the stream `of fuel issuing therefrom,

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
