-HYDROCARBON-BURNER.

Specification of Letters Patent.

Patented Aug. 1, 1905.

Application led November 16, 1904. Serial No. 233,012.

A of Virginia, have invented certain new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification. This invention is a burner of novel structural organization intended most specially for utilizing crude petroleum as fuel and for steam boiler and other furnaces requiring intense heat and an extended heating-surface.

The chief objection to the successful utilization of crude petroleum as fuel is the residue resulting from combustion, same depositing in the pipes, connections, and adjunctive parts of the burner and impeding the passage of the oil, vapor, and gases. This invention provides for the separation of the gaseous mixture, the more volatile and rarefied fluid passing to a high burner or burners and the heavy mixture to a relatively low burner of such proportions as to admit of any residue or deposit being easily and quickly removed. The burner is also constructed with a view to admit of access being had to the parts for cleaning at regular intervals when the device is in constant use, thereby assuring its effectiveness at all times--an essential attribute of a burner of this type.

For a full description of the invention and the merits thereof and also to acquire a knowledge ofthe details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.

While the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment thereof is shown in the accompanying drawings, in which- Figure 1 is a perspective View of a burner embodying the invention. Fig. 2 is a central longitudinal section thereof.

Corresponding and like parts are referred to in the following descriptionand indicated in both views of the drawings by the same reference characters.

In its organization the burner comprises complemental generators 1 and 2, the latter acting in the capacity of a superheater for rarefying or thoroughly volatilizing the vapors passing thereto from the primary generator 1. The generators 1 and 2 are of similar construction, each consisting of a circular rim or band, and heads 3 and i threaded into the rim or band and provided externally with angular projections 5 for reception of a wrench, Spanner, or other tool by means of which said heads are tightened or loosened as may be required. The generators are comparatively shallow, so as to insure every portion of the liquid or vapor coming in contact with the heated walls, so as to be ashed or rapidly converted into gaseous vapor. A

pipe 6 connects the generators 1 and 2 and is thereof at a point diametrically opposite the pipe 8 and'is provided with a valve 11. The pipe 10 is adapted to be connected to a suitable source of suppl y, the oil being forced therethrough under pressure by means of a pump or other equivalent means. A steam-pipe 12 connects with the oil-supply pipe 10 at a point between the valve 11 and the generator 1 and is provided with a valve 13. The oil and steam commingles at the juncture of the two pipes 10 and 12, the oil being heated and atomized and delivered in this condition into the generator 1, where the major portion is converted into gaseous vapor and passes through the pipes 6 and 8 into the generator 2 and is superheated and thoroughly vaporized so as to be consumed at the burners.

A header 14 lis arranged transversely of the complemental generator and is composed of a series of pipe-fittings-such as Ts, nipples, and four-way couplings, the latter being arranged at the extremities of the header, asindicated at 15.

A pair of burners 16 are located upon op-- posite sides of the supply-pipe 10 and are inclined slightly to the horizontal, so as to direct their fiame upon the generator 1. The burners 16 may be of any structural type of the Bunsen variety and are connected to the header 14 by short vertically-disposed pipes provided with valves 17, by means of which the supply of gas is controlled. Plugs 18 close the outer ends of the burner-tubes 16 and when removed admit of access to the burners for removal of any residue which would tend to plug the same. A third burner 19 is arranged below the plane of the complemental generators and is connected to the header 14 by means of a pendent pipe 20, provided with a valve21. A plug 22 closes the outer end of the burner-tube, for a purpose similar to the plugs 18. The burner 19 is centrally disposed and is of larger proportions than either of the burners 16 and receives the heavier gases, the lighter or more volatile gases passing to the burner 16. A spreader 23 is arranged below7 the generators 1 and 2 and in the same plane with the burner 19 and is preferably constructed of refractory material, such as iire-clay, and consists of a slab or tile lhaving a plurality of ducts 24, through which i the vapor from the generator 19 passes. Longitudinal pipes 25 connect the opposite ends of the header 14 with a transverse pipe 26 at the rear of the burner, four-way iittings 27 coupling the pipes 25 and 26, and, like the four-way ttings 15, have their outer ends closed by means of plugs 28, which when removed admit of an unobstructed passage through respective pipes 25 and 26 and the header 14, whereby any deposit of residuum may be removed. A receiver 29 is coupled to the pipe 26 and generator 2 and acts in the capacity of a storage-chamber for equalizing the supply of gas to the respective burners and insuring a steady and uniform flame. The ends of the receiver 29 are closed by removable plugs or caps 30 to admit of the same being easily cleaned.

From the foregoing it will be readily understood that the construction is such that access may be had to every part for removal of any residue or deposit, thereby assuring the efciency of the burner by proper care at stated intervals. When starting the burner, it is necessary to heat the generators 1 and 2, and this may be accomplished in any way, either by the application of a torch or by applying a fire around the same of light kindling or in any manner determined upon. After the generators have been heated the valves 1 and 13 are opened and the atomized oil is delivered into the primary generator 1 and is wholly or partly vaporized and passes from the generator 1 into the generator 2 and is superheated or completely vaporized or rarefied and passes from thence through pipes 26 and 25 into header 14 and from thence to the respective burners 16 and 19. It will be observed that the component parts of the burner are compactly arranged and located within the heating zone of the burners, so as to prevent condensation of the vapors, and the controlling-valves are so arranged that any part may be temporarily shut off to admit of inspection for cleaning after the required plug or plugs have been removed.
