BURNER.

SPECIFICATION forming part of Letters Patent No. 482,145, dated September 6, 1892. I

Application filed January 4, 1892. Serial No. 417,032. (No model.)

To all whom it may concern:

Be itknown that I, EDMUND T. VIGG, a subject of the Queen of Great Britain, anda resident of the city of London, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Burners, of which the following is a specification.

The object of this invention is to provide an improved apparatus by means of which heat is obtained from the combustion of the icombination of the surrounding atmosphere with the vapor generated from gas-oil (a low grade of petroleum) or other liquid hydrocarbon and the perfect combustion of the same by oxygen taken up and combined therewith from the surrounding atmosphere; and it consists of the improved construction and combination of parts of the same, all of which will be hereinafter first fully set forth and described, and then pointed out in the claims.

Reference is had to the accompanying drawings, which form a part of this specification, wherein- Figure lis aside elevation of an apparatus having a double burner embodying my invention and shown in a stove or furnace, with the front plate of the latter removed to show the apparatus therein. Fig. 2 is a central longitudinal sectional view of the apparatus shown in Fig. 1. Fig. 3 is a sectional view of the retort on the line a; x of Fig. l. Fig. 4 is a sectional view of the combined superheater and abutment on the line a a of Fig. l. Fig. v5 is a side elevation of an apparatus having a single burner embodying my invention. Fig. 6 is a central longitudinal sectional view of the same. Fig. 7 is a sectional View of the combined superheater and abutment on the line a a of Fig. 5. Fig. Sis a sectional view of the retort on the line :r o; of Fig. 5.

Any liquid hydrocarbon may be used with perfect safety in this apparatus; but from the particular construction and operation of an apparatus embodying my improvementsl am enabled not only to burn a large portion of the surrounding atmosphere as fuel, but to form a perfect and complete combustion of gas-oil, (a low grade of petroleum,) which from its loW price enables me to provide an apparatus the fuel for which can be supplied at very little expense, and not only this, but when the burner is once started it will continue burning without the necessity of continual supervision which ordinary furnaces require in the person of an engineer or lireman, so that an apparatus embodying my improvements effects a large saving in running expenses over those where a more expensive fuel is used and where continued supervision is required.

This gas-oil or other liquid hydrocarbon is piped from the tank A to the retort C through pipe B, a valve b in the latter regulating the supply to said retort C. This tank A is placed in an elevated position, as shown in Fig. l,in which case the oilis intended to be fed by its own gravity. This retort O is formed with the openings C,the sides of which are walled,

as shown in Fig. 2, to prevent the escape of the contents of said retort at this point, and communicating with the interior of said retort O is the pipe D and the petcock E, and this retort is also provided with the lugs O2 and @anges O3. The latter extend around the openings O and increase the length and draft and direct the iiame against the solid under side of the superheater G, the under side of which forms the abutment.

F designates a nre-pan provided with the slotted standards f', in the slots of which standards the shanks of the screw-bolts which bind the lugs C2 and the standards f together may be vertically adjusted to support the retort and attachments at any desired position or elevation in the furnace-chamber.

G designates a combined abutment and superheater, within which is formed the winding passage G', and the pipe D from the retort C communicates with this passage G near one end, and with the other end of this passage the pipe D communicates, and the latter extends down through the retort, and an opening or openings d2 are formed in this pipe D', at which point the vapor escapes and is ignited, and where this pipe D extends through the retort the latter is walled to prevent the escape of its contents at this point, and d3 are shields surrounding the pipes D D between the retort C and superheater G to prevent said pipes from being injured by the action of the heat as the dame rebounds IOO from the under side or abutmentiof the supei-heater G.

The petcock E is used in connection with the retort C in order to draw olf any impurities or refuse which may remain in said retort after the oil is vaporized and also to supply a'little oil to the fire-pan, which is ignited and heats said retort to commence the operation of vaporizing the oil therein, which vaporization is afterward continued by theXcom` bustion of the vapor and the surrounding atmosphere as said vapor passes out through the opening d2 in the pipe D'. By opening this petcock E before shutting down the fire or turning oif the supply of liquid hydrocarbon the expanded Vapor rushes out of the retort through this petcock E and carries with it every particle of impurity in the retort, thus leaving the latter perfectly clean andin the best condition to again commence the operation of vaporizing the oil. The flame from the combustion of the Vapor and the surrounding atmosphere passes through the opening or openings C and strikes against the under side of the superheater G, which forms a solid abutment and retards the ame and heat at this point, which not only causes a perfect combustion of the gas or vapor and air, but heats to a high degree said superheater G, and as the vapor passes from the retort C through the winding passage G it is exposed to and passes over a large area of heating-surface in order to become highly superheated and xed into a gas, which passes down through the pipe D to the opening or openings d2, at which point it is ignited, as before stated.

l-I H designate screw-plu gs in the retort and superheater, which may be removed to extract any large impurities from these parts. They are supplemental, however, and it isonly in exceptional cases that they would be removed, the petcock E effectively and practically answering for this purpose.

K designates a partition-wall formed of any suitable non-combustible material, and it is situated about on a line with the retort C, which partition separates the furnace or chamber in which this apparatus is placed into two apartments, and an opening K is formed in this partition K large enough for the retort C to rest in, or the partition K may be placed immediately under and rest adjacent to 'said retort, as shown in the accompanying drawings, in which case an opening or openings K' are formed therein opposite the openings C of the retort C, so that these openings C', extending through the retort C, are the only communicating passages between the two apartments of the furnace. The lower apartmeut of this furnace only is provided with suitable ample openings (not shown) for the admission of fresh air, and the only opening which it can pass through from the lower to the upper apartment is the opening or openings C', and it is drawn through these in large volumes by the force of the vapor escaping from the opening d2 in the pipe D as it rushesup through said openingG,so that all the air passing through the furnace or cham ber in which this apparatus is placed must pass through the openings C. This brings large volumes of the surrounding atmosphere in direct contact with the burnin gvaponwhich `takes rup the oxygen therefrom, and this, to-

gether with the abutment formed by the solid under side of the superheater G against which `the gias or vapor and air strike, causes a cornplete and perfect combustion of both to take place; and,further,byusingthispartition-Wall as just described all the air entering the furnace or chamber in which this apparatus is placed must pass up through the openings C in the retort C.l This enables the feed of the oil to this apparatus tobe wholly accomplished by its gravitation without the assistance of air-pumps or other force. r

The operation of the apparatus with a single burner, as shown in Figs. 5, 6, '7, and8, is identical with that of the double burner shown in Figs. l, 2, 3, and 4, the only difference being 'in the number of openings C through the retort C and the number of branches of the pipe D; but any number of openings C and branches may be used in the device shown in Fig. 1, or any number of single burners shown in Fig. 5 may be used to attain the required heating capacity.

Having thus described my invention, I claim- 1.
