lfo'fall whom it may concern:
Be it lknownthat I, ANDERS AKEsoN, a
Icitizen df theUnited States, residing at the c ity of Worcester, county of lVoreester, and
State of Massachusetts, have invented certain new and useful Improvements in Hyy drocarbon-Burners, of which the following is 1. a specification; l
My invention relates to the class of hydro- .10' carbon burners for heating purposes, and it 1 qOnSists of the novel construction, combinaion andv arrangement of parts, as herein- `fter specified and claimed. i The purpose of m invention is to feed i J5' several liquids, drop y drop, from suitable tanks.or reservoirs, by means of gravity alone, into the vaporizing tubeor chamber, Where they are minutely. subdivided and f #thoroughly mingled, and also to provide 2p means for the combustion of the vapors and Agases so produced. A f In the accompanying drawings, like re'ference characters indicate like parts..
Figure 1 is a central vertical section of m'y 275 improved hydrocarbon burner, and, Fig. 2' is a central vertical section of a modified form of r y invention. l The v porizing chamber 1' is a tube hav- I in air inlets or openings 2 near its top. The
` tu e or lchamber 1 has at its upper end a feed. chamber 3, .whose `exterior surface is substantially cylindrical with.. an annular i flange 4 extending therefrom. .The charn- `ber 3 has,an annular shoulder 5 to enable it to it upon the upper edge of the tube 1 and g tol enterre-1nd close the upper' end of said tube. A nozzlel 6, integral' with the cylindrical' feed chamber, projects centrally downward intothe tube or 'chamber 1 and has a taper* ing bore, as seen in Fig. 1. The interior of the `chamber 3 is tubular at and near its center, and; funnehshaped at its bottom, and opens into said bore of the nozzle 6. The `upper end of the chamber 3 is beveled jinternally.
l. An air drum 7 is tubular in shape and has ltwo concentric sleeves or extensions 8 and 9 fat its ends, respectively. This drum is provided with a series of air inlets 10, 111. The
sleeve 9 is of larger diameter thanfthe sleeve 8. The u per end of the vaporizing tube 1 iits into t e sleeve 8 and said end is flush with the upper edge of the sleeve 8. The air inlets 2 of the tube 1 are in close proximity .to the air inlets 10 11 of the drum: or .cylinder 7 The wall of the feed chamber 3 is tapped for the reception of three nozzles and two vent plugs. At the to p is the nozzle 12 having a liange 13 which rests upon the top of the chamber 3 on the outside of the same. 14 designates the feed pipe, and a valve 15 is placed between said pipe and the nozzle 12 and is o erated by the handle or wheel 16. Alcoho is fed to the chamber 3 through the pipe 111, valve 15 and nozzle 12 from a suitable tank or reservoir, not shown. Adjacent to the alcohol feedV nozzle 21, are two vent*` plugs 17 and 18. The vent plug 17 is shown in Fig 1 as openfand the vent plug 18 asfclosed. Each of said plugs has a knurled head 19, by which it is seized and turned. As indicated in each plug in dotted lintes, there is acentral longitudinal passage, whose upper portion bends at a right angle and opens through. one side.-
The veiit lug 17 is shown o en or unscrewed unti the outer end of sai bent passages is out beyond the exterior surface of' the chamber 3. The vent plug 18 is sh own as closed, that is, said outer end of the passage is between the inner and outer surfaces of the chamber 3, iii the top wherein said lug is mounted. The opening of either or oth said lugs allows the entrance of air into the cham )er 3, to enable the flow of the liquids from the nozzles 12, 20 and 25 to pass from the nozzle 6, of said chamber, into the vaporizing chamber 1. Near the vent plug 174 is the nozzle 20, having the flange 21 which fits closely upon the exterior of the chamber 31 A feed pipe 22 conducts water from a suitable tank or reservoir, not shown. A valve 23 connects the feed pipe 22 and nozzle 20 and is operated by the handle or Wheel 24. Near the vent plug 18 is the nozzle 25, having the flange 26 which fits closely upon the exterior surface of the chamber 3. A feed pipe 27 conducts kerosene from a suitable tank or reservoirhnot shown. A valve 28 connects the feed pipe 27 and nozzle 25 and is operated by the handle or Wheel 29.
As represented in Fig. 1, the end of the indicated by the'arrows 30 and 31,. respec.
tively. A dished inverted plate or disk 32 has a` tubular sleeve 33, which lits upon the air drum 7, and is secured thereto byI screws or otherwise. A large tube 34 has at its u per end a bent flange 35 which 'fits upon t ie sleeve 9 of the air drum 7 and abuts the lower' end, or shoulder of said drum. The tube 34 lis an air tube and surrounds the vaporizing tube or chamber 1 concentrically. 'lhe tube 34 is open at the bottom and extends downward slightly below the lower end of the vvarilorizing tube or chamber 1. An inverted dis ed-shaped plate or disk -36 has two sleeves 37 and 38, of which .the former fits upon the outer surface of the air pipe 34 and is secured in place by screws lor otherwise. A globe-shaped heater 39 has a sleeve 40 which fits upon the sleeve 38 of the plate or disk .36, and is supported in position by screws or otherwise.- Said heater has a funlnel 41 in which a chimney pipe 42 lits, and it also has a sleeve 43, which isclosed b a door .or cover 44. 'lhe -iire pot 45 is hol ow and hemispherical in shapje, and is supported by 55. Studs or legs 46, which rest u on the bottom of the heater 39. It has a aring mouth or Irim 47 on its up er edge. The hre pot 45 has an asbestos ining 45a on the bottom thereof.
A'doine 48 is symmetrical in shape with the. Aiire ot 45 and has the flaring inouth'or rim 49, ut inverted, and a concentric sleeve 50, which fits uponl the air pi e 34 and supports the dome, being fastened by screws orl otherwise. The rims 47 and 49 of the re pot and dome, respectively, are parallel with each other and se arated by a considerable space, as shown in ig. 1. v A
Tlie'combustion chamber is made of two hemispherical shells 51, 52. The upper half 51- of the combustionl chamber has asleeve 53, by which it is supported on the air pipe 34 and Asecured by screws or otherwise. It also has a iiange 54. p The lower hall has a fiange bolts 56, secured into threaded holes at e uiespaced intervals, 'secure the upper and ow .zr halves of the combustion vchamber at the iianges 54 and 55, leaving ,there a centralspace 57.. The lower half 52 of the combustion chamber has a centralv directed bulge 58, which serves as a deiieetor. A dischargin tube 59 has a number of apertures or out etsl 60 on its sides and is provided with a sleeve orcollar 61, which. fits upon the lower end of the chamber 1.V y The tube 59 is open at its' bottoni and extends partiall nearly alf-way down the latter. The tube 59 isvconcen'tric with the tubes-1 and 34, but
vis less in-diameter than the tube 34.l .Near
. the deiiector 58, the lower part l52 of the opened and 'a lighted match is combustion chamber is provided with a series of openings or apertures 52, as shown in he following is a descriptionof the operaroc'arbon burner. The asbestos lining 45a of' the fire pot 45 is saturated with kerosene. rThe door 44 is applied at some point between the rims y47 and 49 of the'iire pot 45 and the dome 48. The door 44 is then instantly closed. The -liquid fuel,
over and aroundg'the deflector 5 8,
withwhich the asbestos lining has been sat urated, is thus ignited and burns rapidly,` sol that the combustion chamber 51, 52, is 'al' most immediately heated to a sufficient -de-y gree to vaporize the liquidsabout to' be fedY thereto. er by opening the valve 15, andvilows by gravity down through thenozzle 12,' drop by drop, into the feeding chamber 3 and thence through the nozzle 6 into the vaporizing chamber or tube 1. Next, the kerosene 'is fed to the burner by opening the valve 28v and llowsby gravitydown through the nozzle 25, dropby drop, into the feeding cham# ber 3, and thence through the nozzle 6 into the vaporizing` tube 'or' chamber 1.- Next,y the water is fedto the burner by opening thel valve 23 and flows by gravity down throughthe nozzle 20, dropby drop, into the feeding chamber 3,- and thence through the nozzle' 'into the vaporizing tube or chamber- 1.
A The air currents, indicated by the arrows 30 and 31, throughthe air inlets 10, 11,` 2 together with the outward draft through the chimney pipe 42, as indicated by the ar'row 62, 'rush strongly down throughl the vaporizey ing tube or chamberl 1, as'indicated by the arrows 63 and serve to dissipate the drops of' the several liquids into spray or fine' particles. This result is facilitated by the drops' of water,l which, beinglof the' greatest density, break up the drops of alcohol and kerosene, but are themselves se arated and subdivided into smaller and s'mallerglobules by the contact as also by thestrong air dra t already described',- and thus these fluids' are thoroughly mixed and mingled. The lower part,
. however, of the vaporizing chamber or tube, 1,- is heated from the iiames in the fire potv 45,
and this heat lchanges the liquid contents of the tube or chamber "1 into hydrocarbonvapor,v which, as it rushes out through the apertures of the discharging'tube' 59 into the combustionchamber51, 52 (as indicated by the arrows'64)'isjign,ited in thecombustion chamber and between the stud bolts 56; through the space lower halves 51,
chamber, as indicated b thence into and out of t the arrows 65, and
ing through the air pipe 34, as'indicated by The plates 'or disks `32, 36 and the air `s ace between them prevent excessive radiation upward from the l'ieater, and so the feeding device and the contents t protect iereof.
between the up ei* and;y 52, of. the corri ustioni l e dome 48 or out of' the aperture between the dome 48 and i're pot 45,
thoroughly decomposed in theiire pot 45 an 0 The alcohol is iirst fed to the burnthrough the apertures 60 of iso l,my improved hydrocarbon bur'ner.
In Fig. 2 is represented a modilication of In this the vaporizi-ng chamber or tube 69 is much shorter than' shown in Fig. 1, and its upper part is not inelosed in the air pipe, as in liig. 1, and its lower part is not provided w ith a -discharging tube with apertures,vas hereinbefore described. `A flanged collar 7 0, having air holes 71, rests on the plate 32 and supports the air tube 72.. The air tube 72 supports, a's already described, the dome 4S by means ofthe collar 50 and the upper half l .The air tube 72 extends below the lower endl with said space between the upper and lower.l halves 51, 52, of the combustion chamber.`
51 of the cornlnxstion chamber by means of the collar 53, and the upper hs lf 51 of `the combustion chamber, bymeans of its flange 54. The bolts 56 su `port the lower half 52 of the combustion c iamber, and provide a space between said upper and lower halves.
of thevaporizing tube 69, and near its bot toinhas a row of holes 73, which are in line The air enters the vaporizing tube or chamber 69 throughthe air holes 2 directly from the external atmosphere, as indicated by the arrows74. Thedrops of alcohol, kerosene and water .pass from the nozzle 6 down through the tube or chamber 69, as indicated' by the arrows 75. Theair enters the tube 72 from the external atmosphere through the air holes 71, as indicated by the arrow 76. At the bottom of thetube 69 the vapor descends therefronnas indicatedby the arrow 77, into the lower portion of theltube 72 (which is the v equivalent of thedischalrgingtube 59 of Fig.`
` 1) and there rningles with said vapors, as indicated by the arrows 78, with the same result as hereinbefore described.
The deflectingplates 62 and 36 serve to protect thehydrocarbon feeding device from the'heat caused bythe burner or .combustion chamber in lthe heater 39 and radiating from .the latter. i One of such deilectors is useful,
but by having two arranged parallel to each other, with an intervening space, thev are more eflicient to interceptthe heatand prevent danger to the feedingl` means.
