HYDROGABBON-BURNER.

burner being of the type wherein the fuel is atomized or distributed and burned by means of steam or air under comparatively high pressures. g

A preferred form of burner constructed in accordance with the invention is illustrated in the accompanying drawings wherein Figure 1 is a plan view of one form of burner, the fuel and the air or steam chainbers being indicated in outline by dotted lines; Fig. 2 is a front elevation of the same;

Fig. 3 isa rear elevation of the same; Fig. 4.

is a. longittuliual vertical section of the same on the broken line i -4: of Fig. 3; Fig. 5 is a. vertical transverse section on hne 5-5 of Fig. at looking in the direction of the arrows; Fig. 6 is a front elevation of a modi fiedform of burner adapted for the production of a larger flame; Fig. 7 is a vertical longitudinal section of the broken line 7-7 of Fig. 6, and Fig. 8 is a sectional view illustrating a modified form of plug provided with a valve-controlled supplementalport .for air or steam.

Referring particularly to Figs. 1 to 5, the

burner is represented as comprlsing a cylin-- drical casing 1, usually of brass, the rearward portion being divided longitudinally by an L-shapedpartition 2 in such manner as to provide a steam or air chamber 3, and

a smallerfuel chamber 4. At the front of the burner a prolongation of the fuel chamber 4 extends transversely across the burner beneath a project-in lip 5, through which extends the central uel port- 6.

4 represents the fuel inlet for connection by means of valved pipes in -o usual way to, and tapers inwardliy to a source of supply fuel under suitable pressure.

8 is an inlet aperture for steam or air, communicating with the chamber 3 at its rear end: the steam or air chamber 3 extends transversely across the casing 1 above the partition 2, and thesteam or air is de:

liver-ed. through a contracted port 9 located" above and to the rear of the lip 5 and in close proximity to the fuel-port 6 in saidlip. The arrangement ofthe fuel and air or steam ports is such that the fuelfiowing upwardly through the port 6 is sprayed or atomized and burned by the jetof air or steam from the port 9, the said 'jctbeing directed across and impinging upon the fuel at its point of discharge: this relative arrangement of thefuel and air or steam ports is such as is commonly employed in the art.

Centrally disposed above the lip 5 in the front wall of the casing 1 is an aperture 10. This aperture is circular in form with the exception of the lower groove or extension 9 forming the air or steam port above referred to receive the plug The forward on of the plug 11 .is (Tapered to correspond to the aperture 10, and when fully retracted accurately closes the same with the exception of the port 9.

The plug 11 extends rearwardly through the and through a cir-- elongated cap-nut 1% extends over the end of'the plug 11, this nut having an accurately beveled bearing surface 15 engaging the outwardly tapering walls 16 of the aperture 12 and forming a steam-tight joint therewith. The construction is such that when the nut 14 is turned to retract the plug 11 the apertures 10 and 12 are simultaneously closed; whereas by looseningthe nut 14 the plug 11 may be thrust forward or completely removed. The port 9 may be cleared of any obstructing matter merely by advancing the plug 11 and utilizing the pressure of the air or steam for clearing the orifice; or in case of necessity the removal of the plug affords free access to the interior of the steam or air chamber.

In case a wider aperture for the discharge of fuel and air or steam is desired, thereby providinga larger flame, I prefer to modify the construction in the manner shown in Figs. 6 and '7. The general. construction and arrangement of parts is as above described, but in order to provide space required for the greater width of the air or steam port 9, the plug 11 is semi-circular "in form at its forward end, its lower flat surface l7-being suitably grooved to provide an air or steam port of the form and dimensions desired. Obviously the groove may be formed in the wall of the casing beneath the plug incasing 1.

} quirec.

It is obvious that in stead of in the plug.

air or steam port may this constructionthe be extended laterally struction is therefore more particularly adapted to burners of relatively great heating capacity.

In Fig- 7 I have illustrated screw-threads 18 formed in the exterior of the cylindrical This feature is equally applicable to all forms of cylindrical burner casings,

and permits any burner to be screwed into place in a furnace wall, shield or the like, thereby protecting both the burner and operator from the heat of the flame. In burners of large capacity it is advantageous to provide the cap-nut 14- with a rearward extension 14 of sutficient length to permit its ready mani/pulation while the burner is in operation.

In Fig. 8 I have shown a further modification consisting in the provision in the plug 11 of a supplemental air or steam port 19 extending to the forward end of the plug above the air or steam port 9, the purposeof this supplemental port being to supply directly to the flame air or steam in excess of that which can be economically supplied through the regular port 19, or which is resupplemental port 19 communicates with the a r or steam chamber 3 through radial ports 20 in tne plug 11, and is controlled by a valve 21 extending through the rear end.

of the plug. In this construction'the capnut 14 may be replaced by a short nut 14",

permitting the operation of the valve 21, from the rear of the burner.

While I have specifically described the adaptation of the supplemental, valve-control ed air or steam port to the form of aperture shown in Figs. 1 to 5, it will be understood that the same is equally applicable to the modification illustrated in Figs. 6 and 7.

The burners of the form described are found in practice to be economical, efficient and easy 'of operation and control. construction provides a relatively large as desired, and the conto atomize or spray the fuel. The

The

asses fuel chamber, the effect when operating the burner with steam being to very effectively pre-heat the fuel and thus to increase the efii ciency of combustion; the construction fur taining combustion with fuels other than the hydrocarbon oils, the burner having proven efiective for the combustion of molasses or the like. The construction of the plugs 11 the air or. steam ports that the burner is capable of uninterrupted service under the most adverse conditions. ,The provision of amounts of fuel than couldotherwise be economically used, and greatly increases the heating capacity of the burner.
