Application filed September 213, 1910, Serial No. 583,7?5.

T all whom it may concern Be it known that l, Ancouu REC/sou, citizen of the United States, residing atNcw York city, in the county and State of New York, temporarily residing in the city of Pittsburgh, in the county'of Allegheny and State of Perms lvania have-invented certam. new and useful Improvements in Jetting Mcthodsof Combustion, .otwhich the following is a specification, reference being hadthercin to the accompanying drawings. This invention relates to What may be called a jetting or sprayin 1 method of combastion of any gaseous inc whether a gas; themixture of gas and air, ora vapor of oil, for examples.

The diflerent forms of apparatus herein shown form the subject-matter of my applications Serial Nos. 583,776 and 583,778,both filed Sept. 26, 1910.

The objects of this method are to produce intenso heat for various industrial purposes, such, for example, as in smelting, reduction, glass-making and cemcnt'burning appa atus; and to improve combustion.

In the accompanying drawings, illustrating the principle of this method by various forms of apparatus and now known to me, both in relation to gas or gaseous fuel and also in relation to oil. vapor, Figure 1 is a central, vertical section of a form of heating apparatus adapted for the burning of a gas or gaseous mixture according to'thc present method. Fig. 2 is another form oi heater, partially in elevation and partially in section, for use in burning; a gas or gaseous fu'cl by the present method.

The apparatus shown is not herein claimed, because it l'ornis the subject-mutter of my application Serial No. 583,776, of even date herewith.

char-ring to the accompanying drawings (Fig. 1), 30 is a bunson provided with the usual air regulator 30 and discharging into a casing 31 provided with a centrally i111" perforate wall and a plurality of surround inc; perforations 33, the linperforate portion being lndlcated by 32 and thewall by 34, which extends laterally beyond the casing 31 to iorin a support for casing 35 located thereon and containing a combustion chamthere is mounted a supply pipe 36 having an imperforate lower end preferably opposite the Specification of Letters Eatent.

imperforate portion" of wall and provided with a plurality lateral perforations 37 all around ts annular wall. From the combustion chamber within casing 35, exhaust pipes 38 for products of combustion lead to the casing 39 of vacurun creating and maintaining device ill-provided with an ex haust-port Casing is provided with a coverili, which may removed for igniting the fuel contained in the combustion chamber. The: supply pipe 36 is provided, at its end, exteriorly of casing 35, with a screw cover 42: having a threaded shank ll that screws into the crossbar 43 oil the projecting and ol'the supp pipe. It is obvious that the air regulator may he closedto prevent access of to the ounsen 30, in which case its pipe may he used for conveying unmixed. into the chamber 31. It is also ohvious that the screw cover 42 may be entirely removed to allow free supply of air or other comlonstion-supporting gas, such as oxygen, for example, to the combustion chamber through the radial perforations 37; later 30" and the cover 43 may he regulated to vary the amount of air admitted past them.

The casing may he ofsny shape, size or contour adapted for any purpose, such as for heating by radiation, or he formed as a member oi? any desired kind of apparatus for any desired purposs.

When the exhaus fan is in operation and the mixture of gas or gas and al r coming in through the hunsen 30 with the combustion-supporting gas supplied through pipe 36 and entering the coznhiistion chamber through the multitude oi? preferably small perforations is ignited, very intense heat 15 obtained, the products or oomlmstion he ing continuously removed it: i the vicinity of lli'lt3,ilil1lland out of the combustion chamber during conilnistion. The gaseous fuel entering the chamber of casing 31 is jetted upwardly for a considerable distance int the conllmstion chamber, wherein it is intimately mixed with tho combustion-supporting gas which is jetted radially from the tube 36. This crossconnningling jetted or spray Cl gaseous fuel and combustion-supporting gas c fleets a most thorough mixture thereof, which is greatly favorable and that both the air regu-' of the i In Fig. 52 I show another form oi apparatus useful in burning gas or gaseous fuel, wherein. the same is jetted into intimate mixture in acombustien chamber with therein jetted cornbustionsupporting gas or air. In this form of apparatus, bunsen 230,

rovided with an air-controller 230, comunieates ttith an enlarged head 231 contahiingg-a chamber of considerable capacity as'c nil r ounsen, and in which the air or gas, or

t mixture of air and gas, coming in through the combustion chamber to the casing 239 of vacuum creating and maintaining device 2d0, the casing having an exhaust port 239 The top of the casing of the combustion chamber is shown provided with a form of electricalignition device 2&1 for igniting the gaseous fuel as it is jetted or sprayed through the perforations 23d into the combustion chamber, Where it is mixed with air, oxygen or any suitable combustion-supporting gas, that is jetted into the combustion chamber through the perforations 237 in the lower end of the central tubular projection 236.

It Will be observed that the jets of the combustible fuel and the jets of the combustion-supporting gas are at an angle one to the other, so that a very intimate mixture of the combustion-supporting gas and of the gaseous fuel is'obtained in the combustion chamber, wherein the mixture is ignited and the products of combustion withdrawn from the combustion chamber through the exhaust pipes 238 by the vacuum producing and maintaining device, under a rapid move ment thereof, given by a suitable power connection, not shown.

In all forms of my invention 1 have shown the exhaust pipe leading to the casing for the vacuum producing and maintaining device as broken away, to indicate the fact that in ordinary installations, and, generally speak ng, in all manufacturing installations, the vacuum producing and maintain ing device is located at a point sul'jstantially distant from the combustion chamber.

It will be observed that, in all forms of the apparatus shown, the gaseous fuel and the comlmstion-suppm-tin5; gas (Whether oxygen, for example, or air is more usual,)

are introduced at a central. point oi" a Wall ipared with the cross-sectional area of of the casing containing the combustion chamber, so that the latter, in efi'ect, extends in all directions laterally of the combustion point; except, however, that this exists in a modified degree in the apparatus shown in Fig. 2. While What may be called the central introduction of the combustion-support ing gas or air is not essential, it is very desirable in many installations, as it secures an incandescent that extends out wardly for a corisiderable distance from the point or points at which the combustionsupporting gas is introduced; in other words, it secures a lateral annular expansion oi the flame, and is therefore advantageous tor nmny purposes, especially where a large wall area is to be heated.

In the form of apparatus shown in Fig. 2, the heatingplates, as Well as the Whole appartus, may be of any size, shape and material desired; and what I have said of the advantages of the method as practised by appartus su h as is illustrated in Fig. 1 applies to the operation of appartus such as illustrated in Fig; 2.

it Will be observed that the gaseous fuel is burned in a partial vacuum created in the combustion chamber by the artificial suction, and while the fuel is in ahighl'y attenuated vmolecular condition in consequence of the suction. a

The artificial suction apparatus is operable to secure a uniform, continuous suction. I The Word artificial is used in this specification in contradistinction to natural draft means. 1 i

W hat I claim is:-

1. The method of combustion which consists in, forming a partial vacuum at the place of combustion, drawing air and gas thereto in a rarefied condition in separate jets, mixing the same and then burning the rarefied mixture. I

2, The method of combustion which consists in forming a partial vacuum at the place of combustion, causing air and gas to be rarefied, drawing air and gas in separate jets, mixing the same together at the place of combustion, burning the said mixture in its rarefied state and forcibly withdrawing the products of combustion.

3. The method of combustion which consists in simultaneously creating and maintaining a partial vacuum at the place of combustion, cross jetting gases at an angle to each other, mixing and sustaining the gases in a rarefied state, mining the mixture and forcibly removing the products of combustion.

The method of combustion which consists in simultaneously producing a partial umum: at the place of combustion, drawing a jet ol mixed air and gas and a jet of air llicz'otu at angles to each other in a rarefied
