Specification of Letters Patent.

Application filed July 13, 1908. Serial No. 443,387.

To all whom it may concern:

Be it known that I, GUSTAV AnoLr SoHooHn, a subject of the King of Saxony, residing at 2 Kasomenstrasse, in the city of Dresden and Empire of Germany, have invented certain new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

This invention has relation to certain new and useful improvements in hydrocarbonburners in which petroleum, spirit, benzin and the like are first converted into vapor and thereupon mixed with atmospheric air, oxygen or other suitable gases to produce a very high temperature; and the invention consists in the novel construction and combination of parts, all as hereinafter described, and pointed out in the accompanying claims.

In the various hydrocarbon-burners hitherto existing, difiiculties are met with by reason of imperfect vaporization, which results in volumes of thick smoke being given off and which of themselves greatly militate against the calorific effect of the burner. A further defect in existing burners of this class is that they are unsuitable for heating lar 'e surfaces, such as steam boilers, and seldom have proper provision for effective and easy cleaning when they become clogged, few are interchangeable and most of them, even when effective, have the vaporizing contrivance placed outside the burner in such manner as to be in the path of the flames produced, whereby these are obstructed in their course. For this reason the vaporizer is not infrequently a source of great danger inasmuch as the thin metal of which it is composed is liable to melt, whereby the liquid fuel escapes into the fire chamber.

The object of the present invention is to provide a burner which is self contained, has no weak outside points in its construction, admits of being made small enough for lighting purposes as also for hcating'small surfaces, such as a heater'for baths and can be made large enough to produce the steam required to drive a small engine.

A further object is to provide a burner which can be employed in aseriesto heat boilers with the largest heating surfaces at present known, and which, when properly provided with that number of vaporizing units requisite for the size of the burner and the fuel employed, the vaporization will be perfect and no smoke generated, even when the liquid fuel is partly cut off during that time when the full pressure of steam is not required.

A still further object is to provide a burner constructed in such manner as to allow of atmospheric air, oxygen or other gases of high calorific effect being intimately mixed with the vapor produced by the vaporizer, so that a flame of dimensions hitherto unknown in such burners may be produced, with a heating power equal to that produced in chemical laboratories by the employment of chemicals and appliances too costly for ordinary heating and lighting purposes.

A still further object of the invention is to provide a device of novel construction to easily ignite the burner and start the process of vaporization simultaneously.

These objects are attained by the arrangement illustrated in the accompanying drawings, and now to be described.

Referring to the accompanying drawings: Figure 1 is an elevation of the burner, Fig. 2 is a-'vertical section through the center of the same, also showing the igniting device,

Fig. 3 is a vertical section through the center of the burner, showing an alternative form of construction for heating the air and hydrocarbon fuel, and conducting them in a heated condition to the interior of the burner, Fig. 4 is a sectional plan on the line X X of Fig. 2, Fig. 5 is a feed-union employed when it is required to feed to the burner atmospheric air, oxygen or other suitable gas in a quantity suitable to the position of any unit in a plurality of burners, Fig. 6 is a vertical section on the line 3 y of Fig. 7 and Fig. 7 is a plan view of one of the perforated burner heads or jets as shown in Figs. 1, 2, 3 and 4; Fig. 8 is a side view of a plurality of burners mounted on one feed pipe graduated in size and provided with an igniting device composed of smaller burners mounted on a separate single pipe, Fig. 9 is a plan view of the same, Fig. 10 is an enlarged detailed sectional view on the line V V of Fig. 9 showing the principal burners inclined toward each other to economize space, and also showing one ignition burner heating two large burners.

In the drawings in which like letters indicate similar parts in the several views, a designates jets having perforated heads illustrated in detail in Figs. 6 and 7, the number and size of said perforations being adapted to the size of the burner; Z) is the body of the burner having an annular enlargement 0 near its base and rings cl, on the upper part, provided for the double purpose of deflecting the flame and retaining the heat and supplemented by the deflectors f, depending from the rings d by-means of the spiders e. WVithin the body I) are a plurality of thimbles g with intermediate spaces it, having canals m terminating in sacks n underneath the jets a. said sacksn being adapted to receive particles of foreign substances which do not vaporize, said sacks being closed by plugs 0 which can be removed for cleaning. The annular enlargement 0 contains a plurality of jets a and also a plurality of apertures 00, preferably arranged so that jets and apertures alternate. The apertures or air passages 00 have no connection with any part of the apparatus, but serve to conduct air to the flame, to increase the draft and support combustion. In Fig. 3 only one thimble g is shown, the interior thimbles being replaced by a filter of wire gauze, but it is obvious that the plurality of thimbles shown in Fig. 2 may be also used with or without the gauze filter. The union shown in Fig. 2 may be replaced by the feed union 9 shown in Fig. 5., when it is desired to mingle air, oxygen or other suitable gas with the hydrocarbon fuel before it enters the innermost thimble g. r

In the. alternative construction shown in Fig. 8, the oil enters the double feed union at 1 passes through the pipes 8 until it reaches the passage t, and the air enters the pipe u passing into the same passage t, where the heated fuel and air commingle, and pass upward into the interior of the burner.

In Fig. 2 is shown the annular igniting device '0, which is so placed that its upper part, which is open,'is near the level of, the

jets a and contains a plurality of air passages w, as fully illustrated in Fig. 9.

In using my burner in series for the purpose of heating large surfaces, I employ one or more feed pipes and arrange the burners so that the first burner to be fed is the smallest and has the finest apertures throughout, including the perforations of the burner heads or jets a, said apertures increasing in size with each succeeding burner along the course of the said feed pipe or pipes 3/. The ignition burners aa are placed on and fed by a smaller feed pipe 3 3 In using a series of burners I employ a small feed pipe 6?) to conveniently convey to the annular cupshaped ignition device a; mounted on each mentioned thimble and so on into each succeeding space and thimble, passing out of the outermost thimble through the aperture 2' at the top of the same. The mixture, new highly vaporized and the air being intimately commingled with the hydrocarbonvapor, passes down the annular spaces between the outermost thimble and the body 1) into the slantingly bored canals m, to the l jets a where it ignites and burns inan intense blue flame which 1m in 'es a 'ainst the deflectors f and d.

In the alternative construction shown in Fig. 3 the hydrocarbon and air are heated previous to being conveyed to the interior of the burner by passing them through the pipes s and 21 respectively, which coil around the flame and it willthereforebe seen that, in this form, the deflectors fmay be dispensed with, if it is so desired, inasmuch as the pipe coils s and u will perform practically the same function.

The operation of the burners when used in series is as follows: Alcohol is fed in a suflicient quantity through the pipe bl) to the cup-shaped igniting device 4) placed on the smaller burners act which are fed by the pipe g y. A light is applied to each of the igniting devices 4; and, as soon as the alcohol has heated the burners aa sufiiciently, oil is admitted into the pipe 3 which causes the burners cm to ignite and perform their function of heating the larger burners b sufliciently to allow of fuel being admitted to the pipe y to feed the said larger burnersb. When the said larger burners are in use, the smaller ones may be cut off by turning off the supply of fuel to the pipes g y, or;

they may be allowed to burn to supplement the larger burners if desired. The smaller burners am also serve the purpose of furnishing suflicient heat to keep up a small head of steam during intervals when high pressure is not required.
