vAPoR BURNER.
Application filed June?, 1926. Serial No. 114,362.
The present invention relates to improvements in vapor burners and' hasparticular` the water and to other defects in the con-` struction of the burners themselves.
Coming now to the present invention, the general object thereof is the provision of a water cooled burner which is characterized by the previsioni of a plurality of concentrically disposed jackets around the vapor `passage of the burner, together with means for effecting the flow of cooling mediums through the said jackets. y
`Another object is to provide for increasing the efliciency of the burner in and around the tip thereof by the `provision of a construction which operates to reduce, if not entirely prevent the lforming of carbon in the opening of the tip. y
A further object is to provide for the effective mixing'or carburation of the combustible fluid. i y
The above and other ob]ects are accomplished by instrumentalitics pointed out in i the following specification. l
The invention is clearly defined in the claim. y y
A satisfactory embodiment of the invention is illustrated in the accompanying drawings forming part of the specification and in which Figure 1 is a contracted vertical longitudinal section of the complete burner.
Figure 2 is a contractive plan view of the same With a fragment of the forward end portion of the wall removed to .disclose a portion of the interior construction.
Figure 3 is a Vertical cross section on the line 3--3 of Figure 1, looking in the direction of the arrows, and
AFigure 4 is a view similaito Figure 3 taken on the line 4-4 of Figure 1 and looking in the direction of the arrows.
The burner of the present invention coinprises a stock a and a barrel b. The stock is an oblong metalliccasting formed with an opening 5 for connection to a suitable bracket for supporting the device in operative position. The forward end portion of the stock is shaped so as to fit into the barreland the parts are welded together seas to provide a permanent fluid-tight `joint. The rear end portion of the stock a is formed with an obliquely disposed nipple 6 adapted as by havingl an exterior screw threaded surface for connection to a hose coupling for conveying compressed air,`steam or the like to mix with the fuel vapor within the stock a.. rlfhe passage through the nipple is in alinement with the mixing passage 8 which extends upwardly and forwardly through the stock and to a point at approximately the middle portionthereof. whence thepassage directed downwardly and forwardly as att) and terminates in the forward extension 10 disposed axially or substantially so of the stock. A nipple 11 is formed with the stock L and isdisposed preferably above and in angular relation to the nipple 6. The
nipple 11 is adapted for connection to the coupling of a conduit forconveying liquid fuel to the burner. The passage through the nipple is in alinelnent with a liquid fuel passage 12 in the rear end of the stock and terminet-ing in the passage 8. With this construction the upward flow of compressed air or steam through passage 8 entrains the gas or other liquid fuel in passage 12 and operates to effectively combine therewith.
The combination between the components of the combustible mixture is thenlfurthcr refined by the contour of the entire passage made up of the portions 8 and 9 in that the direction of the flow of combustible mixture from the portion 8 is changed by virtue of the location of the portion 9 so that vat the junction of these passages, the combustible mixture is agitated on being required to follow a change in the direction of flow so `that a thorough commingling of the componentsof the mixture is effected.
A chamber 13 is disposed at the meeting ends of the portions 8 and 9 andthe diameter of this chamberis longer than the diameter of either of the passages 8 and 9 so that a portion of the wall of the chamber is disposed in the path of the combustible mixture flowing through the passage 8 and thereby provi-des an abutment. The presence of this abutment operates to break up the mixture and more uniformly distribute the components thereof when the mixture impinges upon the Wall.
A supplemental air passage 14 is disposed forwardly of the passage 8 and extends into the axial extension 10 of the passage 9 and a nipple surrounds the outer end of this passage and is formed integral with the stock and adapted for connection to a supply of air or steam if so required. A removable plug 16 is screwed or otherwise `detachably secured in the upper end portion of chamber 13 and forms a closure therefor. `Wlhen the plug is removed, a suitable instrument may be inserted into either of the passa-ges S and 9 lfor the purpose of cleaning the same.
The barrel b has a centrally .disposed tube 17 which conveys the combustible mixture to the tip as shown, the said tip being connected in the ordinary manner to the vscrew threaded portion `18 at the forward end of the tube. As shown the tube is in axial alinement withl the extension 10 of passage 9 and isv seated in a circular recess'19 in the forward end of the stock a. A circular rib 2() forming the recess 19 provides a bearing surface foran intermediate tube 2l surrounding and'concentricrwith the tube 17 and spaced therefrom so asA to provide an air jacket 22. yThe , tubesy 17 and 21 may be welded to the stock as shown. Tube 21 ex tends forwardly and beyond tube 17 and spacers 23 are provided for supporting the forward end portion of tube 21. A tubular connection 24, preferably of annular contour, is directedk into the air jacket 22 and exteriorly it is provided with a. nipple 25 for connection to a supply of compressed air or steam which is permitted to flow forwardly through'the air jacket and into the chamber 25 for the tip, not shown.v lVith this construction a flow of 'compressed fluid is prof vided for comming-ling with theflanie at the tip and, at the same time, the action` of this current of air or steam in moying over the surface Vof the tip operates to remove carbon depositsthat may form thereon.
,ein outer tube 26` surrounds the tube 21 and the rearendportion of this tube receives a circular boss 27 forming the forward end portion of the stock a.- The tube 26 and stock are preferably connected together by welding, and the boss operates to support the tubes 21y and 26 in spaced relation, and the intervening space 28 provides a water jacket for the barrel. The forward end of the tube 26 is connected by an annular wall 29 to the forward end of tube 21, and this wall provides a fiuid-tight iit for the forward end of jacket 28.
A pair of oppositely disposed division walls 30 and 31 extend longitudinally through the water jacket 28, their rear ends being welded to the stock a and their forward ends terminating short of the front wall 29 as clearly shown in FigureV 2. The walls are disposed so as to interiorly divide the water jacket into upper andflowericompartments which communicate onlyvat the forward cnd portion, as stated, the sides off the division walls being welded to the adjacent surfaces of the tubes 26 and 21. Anipple 32 depends from thev rear end portion of outer tube 2G and an oppositely disposed nipfv ple 33 extends vertically upward from, the tube. T hesc nipples arcadapted for connection to the coupling of a hose for conveying water from a suitable source` into "the water' jacket. The water upon entering into the inlet nipple 32 passes through the lower covmpartment of the water jacket and upwardly and into the upper compartment and outwardly through the outlet nipple 33.` 1
Thus it is to be seen that when the ,burner is in operation, a low temperature is insured by the presence of the water jacket andthe intervening air jacket, so that the defect in burners of this type, due to overheatingof the barrel, is effectively avoided.
Although I have shown yand, described'one cmbodimentof my invention, it isto be un;
derstood that the same is susceptible of various changes; and I reserve the `right to em, w1thin the scopeof ploy such as may come the appended claim.
that I claim is:
vapor burner comprising a barreha stock having an inlet end portion andan outlet end portion and a longitudinallydisposed passage connecting said outlet and in,- let portions, the Youtlet end portion of'said stock being connected to one end ,of thel barrel, the said barrel including a central tubu' lar portion, an open ended air jacket surrounding the same and a water jacket sur-L rounding the air jacketv and interiorly Vdivided into `two compartments communicat# ing` adjacent to the free endportionof the barrel, one of said' compartments having an inlet andthe other an outlet.
