GIL VAPORIZEB. AND BUR-NER.

Burners, of which the following is a full,

clear, and exact description, reference being had to the accompanying drawings, form inga part of thisspecification.

This invention relates to apparatuses for burning oil, and especially to that class of oil burners where the oil is converted into vapor by means of heat, previous to burning; and has for its object to provide a burner of a simple construction where the.

heat or the flame produced by the burner itself, is utilized ior'heating the oil previous to burning.

A further object of this invention is to provide a disposition of a simple character,

whereby the oil is forced to remain exposed for a certain length of time to the heat of the flame before being fed to the burner, thus insuring a thorough -vaporization of the same without the need of any other auxiliary means, and insuring the production of a practically dry vapor under considerable pressure.

A still further object is to provide an improved construction of burner, whereby, the oil vapors fed into the same will be readily and simultaneously distributed through all the various parts of the burner, thus insuring an even intensity of flame at all points.

Oil burners of the type usually installed in steamships,'locomotives, and for the op eration of boilers of diiterent kinds, are rather complicated in design; and are generally based on the mechanical atomization of the-oil. This requires air or steam 1111- a serious inconvenience; but the main source of the inconvenience to be found in these burners lies in their imperfect combustion; the combustible material not being completely burned, produces dirt and refuse,

which accumulates in the burner, plugging the holes, and sometimes entirely stopplng its operation. When burning heavy crude oils especially, these burners prove most incflicient, and are liable to get plugged quite often; so much so, that the boiler installation is usually made much larger than necessary, in order to put a set of boilers into use while another set undergoes a thorough Specification of Letters Patent.

cleaning of the burners, andof the atomizing appliances. I

In my improved device, the oil fed from a storage tank under a limited pressure is compelled to travel n a coiled pipeof considerable length, which is exposed to the direct action of the flame, and it is thus heated and perfectly vaporized before reach. ing-the burner. The oil vapor th us'formed comes out absolutely dry, at a .iigh pressure, and both these qualities insure a properly clean burner at all times.

Referring to the drawings, Figure l is. a perspective view of my improved burner with regulating-valve; Fig. 2 is a sectional plan view of the same, showing in detail its construction; and Fig. 3 isa side view in elevation, partly sectioned,ot the-same. 1 The apparatus is composed of a burner proper, a feeding andvaporizing coil, and a yregulating valve. The burner is composed of an inlet pipe l, leading to a distributing ohamber 2, from which depart a number of tubes 3, provided with many small holes 3' their free ends by an enlarged chamberon collector 4, a. At each end of central chamrais s ret. s ,iois. I

.80 on top, distributed over all the surfaceiof the burner. The drawings show two rows of? tubes, one on each side of the chamber 2,,

her 2 1 provide acover 5, removable, but, which must be normally tightly fixed in a place, to prevent the escape of vapors; and at each end of chambers, 4, I provide a similar .cover 6, for the same purpose, this disposition being most convenient for an ac casional cleaning. of the burner.

The main advantage'ot this form of burner is the si-:- multaneous distribution of the oil vapors to all the tubes, which insures an even intenr.

sity of flame at all points.

In the preferred form of construction of I I my device, to part 2 is clamped or otherwise attached a hollow part 7 by means of part 9; part 7 is provided at the two ends with two hollow uprights 8, 8', not in direct communication with the inside of part 7 all these parts being substantially built, and i i made of a good heat conducting material.

.Upright 8 is fitted with the feeding pipe 10, coming from the source of supply, and

upright 8 is fitted with pipe 11, leading to the regulating valve 12, which opens right in front of inlet pipe 1. Part 7 is mounted,

as shown, above burnenand the communi- I cation between uprights 8..and S'Liis estab lished by means of a flat coil 13 having a number of turns disposed around the center, and havingiits inner end attached to point 14- of upright 8", and its outer end attached to point of hollow part 7 and by means of a similar coil 13' attached at 14: to upright 8 and in 15 to part 7. These coils 13, 13 are held at a certain distance from the burner, so that the flame issuing 0 from the latter can heat the former and .Parts 7, 8, 8', and 9, will contribute to keep coils 13, 13 at a high temperature,

a the same being substantially built of a good g0 heat conducting material for the purpose 30 around all the turns of the same, and at 14:

of storing heat.

Valve 12 can be of any suitabledesign, provided the same be capable of giving a good regulation.

The oil fed with a moderate pressure through pipe 10 to 8', enters coil 13 at.

point :14, goes around all the turns of the same, then it enters the hollow space of part ,at l5; at 15' it enters coil 13, it goes it enters hollow upright 8, and is led throughpipe 11 to regulating valve 12. The

vapor escapes from valve 12 at a. considerable pressure inthe direction of inlet pipe 1, through which it travels to chamber 2 to be distributed to all tubes 3, coming out from holes 3', when it is ignited.

When the burner is in operation, the oil vapors in the piping will produce a back pressure, audit will then be necessary to increase the pressure of feeding to a point sufiicient to counterbalance the same, and the frlictional resistance opposed to the flow of 01 Tostart the burner, it is necessary first to heat the coils and the part 7 sufficiently to produce an initial vaporization of the oil, and. this can be done either by temporarily installing an alcohol burner underneath,flor by feeding a combustible gas to the inlet pipe 1, through a separate source, or in any other suitable manner. Parts 7, 8, and 8, not to be essentially of the shape shown; the same being substantially bui t of. a good. heat conducting material, will help in heating coils 13, 13, and in maintaining'the heat in the same.

I am. aware that the vaporization of the oil previous to burning by means of the flame issuing from the burner itself, has been used in many types of burners; in some of these however, the mechanical ar rangement is rather inefficient, with the consequence that the, vaporization of heavy oils is only imperfectly obtained. This is someroaasra times due to the fact'that the distribution of vapors in the burner takes place from This disposition gives an intensity of flame always decreasing as the combustible gases progress through the passages, with the additional inconvenience that at a certain tically the same time, producing an'even height and intensity of flame at all .points. Especial importance is attached to thefact nection with my presentdevice, are held above the burner at a distance from the same. This gives free access to air underneath the coil, therefore permits the combustion of the oil vapors issuing from said part of the burner, to properly take place. Owing to this disposition, the vaporizing coil is at the same time exposed to the hottest part of the flames, and the va orization induced in the same will there ore be more rapid and complete. The peculiar shape of the vaporizing coils is also partly responsible for the excellent results which can be obtained with my improved burner; in fact, the same being Wound with several convolutions in the same plane, for a very long passage exposed to the heat of the flames, through which the coil has the ossibility of being. thoroughly vaporize the various convolutions are close one to the other, as shown in the drawing, there is the additional advantage that only part of the flames are concealed from direct action on the boiler, and that radiation of heat from the vaporizing coil is very much re-[ duced.

My invention can be modified in many of its details without departing from the fundamental idea, governing the same; and

device such modifications and improvements which may properly enter under the scope of my claims. 1

Having thus described, and ascertained the nature of my invention, what I claim as new, and desire to secure by Letters Patent of the United States is:
