HYDROCARBON BURNER NEW JERSEY.

vented a certain new and useful Hydrocar-- bon-Burner, of which the following is a specification. i I This invention is a hydrocarbon vaporizer and burner, and, more particularly, it is designed as an improvement, in a certain particular, upon the apparatus disclosed in a prior application filed byme on July 8, 1908, SerialNo. 441,818. In the apparatus described in the aforesaid application, steam or air is suppliedunder pressure to a series of jet nozzles from a chamber in communi cation with said nozzles, and jets are projected by these nozzles; into a mixing chamber so that said jets operate to entrain and carry a combustible vapor, (preferably re sulting from the vaporization of'oil brought into contact with a heated surface, such as a vaporizing plate.

ractical experience with a vaporizer and burner of the type described shows that the jet nozzles,or the orifices through which the jets are projected, are liable to become clogged or obstructed by the deposit of sediment therein or by the formation ofscale.

of the vaporizer and burner. y

In the accompanying drawings I have illustrated one practical'embodiment of the invention, but the construction shown therein is to be understood as illustrative, only, and not as defining the limits of the invention. i

Figure 1 is a plan view ofa vaporizing burner embodying this invention. Fig. 21s a vertical section through a part of the burner shownin Fig. 1. Fig. 3 is a vertical cross section'on the line33 of Fig. 2, and

ing stems adapted for operation'in one of the injecting nozzles. I

I The burner, or as it may be designated, a combined vaporizer and burner, of the class described in the aforesaid applicationis shown in Figs. 1 and 2, by reference to which it Will be seen that said burner consists of a cylinder, A, provided at one end with asubstantially frustoconical head, a, and a vaporizing plate, Said vaporizing plate is provided with a plurality of openings, b, and with a depressionor cavity, Z), (see Fig. 2'). The head, a, of chamber, A, is provided with a nu'mberiof openings, a,for the ingress of air into chamber, A, and as disclosed in the aforesaid application, said head, a, is providedfwith other openings, c, which are adapted to be partly or operative relation to vaporizing plate, B, I

(see 2). Thiscasting is provided with an interior chamber, 6, preferably annular in shape, and with this chamber, 6, oommuni cates means for supplying steam or air to said chamber for the purpose of maintaining steam or airunder pressure therein. As shownla steam pipe, E, is attached to casting, D, so as to communicate with pressure chamber, 6, whereby steam may be supplied to said chamber, If desired, the pipe, E, may be associated with a super-heating coil asdisclosed in the aforesaid application, but for some purposes, the super-heating coil is dispensed with,'and live steam is supplied under boiler pressureby pipe, E, to pressure chamber, 6. I j

, Casting, D, is providedwith a front'plate, 6', and a rear plate, 6 said front and rear plates being preferably integral with casting, 1), and forming the wallsof pressurechamber, e. Front plate or head, 6", provided with a series of openings, 7, corre spon'ding in number and position to openings, b, of vaporizing plate, B, and in these openings, f, are screwed jet nozzles, F. Said nozzles are tapered andthey extend forwardly from plate or head, 6, into the openings, b, but'said nozzles do not fill said openings, thus leaving free spaces between the walls of openings, Z), and outer surfaces of nozzles, F.

The salient feature of the present invention consists in the employment of means for removing any sediment which may lodge or accumulate in openings, 1), of the vaporizing plate, B, or in the passages of nozzles, F, whereby the steam passage or passages are kept in an open, free and unobstructed conditionso that steam will pass into the chamber of cylinder, A, and the combustible vapor .will be entrained by the steam jets, as Will presently appear.

As shown, the sediment removing means i consists of stems or spindles, G. Each that itmay be reciprocated or moved lengthhand when it becomes necessary to reciprowisein the stuffing box and across pressure chamber, 6. Said stem is provided at its outer exposed end with a knob or head, h, and this knob is adapted to be grasped by 'cate the stem or, spindle. As shown in Figs.

2 aud t a series of stems, G, are employed,

one for eachnozzle, F, and each stem is supported by the stuffing box in alinement with its nozzle, F. Normally, stems,G, are drawn away from nozzles, F, so that steam will pass freely from pressure chamberye, into.

nozzles, F, but should it become necessary to remove a deposit of sediment from nozzle, F, the attendant presses stem, Gr, inwardly. This operation causes the forward end of stem, G, to pass through nozzle, F, and to eject therefrom any matter or sediment which obstructs the steam passage in said nozzle. Obviously, the openings, 6, in vaporizing plate, B, may also become obstructed by the deposit of sediment, and it is necessary,-therefore, to remove sediment from saidjet openings, 6. The stems employed according to this invention may be forced entirely through jet nozzles, .F, and also through jet openings, 5, thus simultaneously cleaning out the passages of the jet nozzles and the openings, (2, in vaporizing plate, B.

a It isto be observed that stems, G, operate across pressure chamber, 6, and. that each stem jis'eXposed at one end outside of the burner. The stufling boxes preclude leakage of steam from pressure chamber, 6, around stems, G. 1

As shown more clearly in Fig. 2 casting, D, is provided with a hub or sleeve, '11, and

into this sleeve is fitted and secured a short tube, I, the inner end of which is positioned opposite to depression, 6, of vaporizing plate, B. The outer end of tube, I, is closed by a head, 2', and to this head is attached one end of the feed pipe, J, thela'tter being adapted to supply fuel, preferably, oil, into tube, 1. Oil is supplied under pressure by pipe, J, and it impinges on the vaporizing plate, B, whereby liquid is vaporized-by contact with said plate, B.

K designates a pipe attached to casting, D, and communicating with chamber, 6, so as to carry off water of condensation which may accumulate in chamber, "6. Pipes J, K, are provided with cocks, j, /0, respectively.

The operation of the apparatus will be,

apparent from the foregoing description taken in connection with the drawings, but it may be described as follows :Steam from any suitable source is supplied to pipe, E, and conveyed thereby to chamber, 6, whereas oil is fed by pipe, J, and projected through tube,.I, in the form of a spray or jet against plate, B. The steam issues from nozzles, .F, in the form 'of jets which are projectedthrough openings, Z), into the mixing chamber of cylinder, A, and the steam jets entrain the vaporized fuel into said mixing chamber. Simultaneously with these operations, air is drawn into the chamber of cylinder, A, and the steam, fuel and air are .commingled in said chamber and burned therein. The combustion thus set up heats the apparatus, and plate, B, thereof and in the operation of said apparatus, plate, B, vaporizes the oil thrown against it, the vaporized oil beingentrained by the jets from nozzles, F, through openings, Z),

into the chamber of cylinder, As previously stated, one or more of the openings, 6, and nozzles, F, either separately while the burner is in operation.

Having thus fully described the invention, what I claim as new, and desire to secure by Letters Patent is: V

1. In a hydrocarbon burner, the combination of means for supplying air thereto and for regulating the quantity of air, an oil chamber, means for supplying oil to the oil. chamber, the forward wall of said oil chamber forming a vaporizing plate, said vaporizing plate having a solid central por tion and an exterior perforated portion, a steam chamber concentric with and surrounding said oil chamber wherebythe oil in the oil chamber may be heated prior to vaporizing it, nozzles leading from said steam chamber and alining with the perforations in the vaporizing chamber, and manually operated means for removing obstructions from said nozzles.
