The object of my invention is to provide a burner ot this type having an improved 'form of `steam superheater that `is internally. provided with asteam expansion area or space that will tend to maintain a substantially constant pressure ci' steam within the superheater so that the steam will not back up into1 the generator and tanks or flow too rapidly into the burner pipe to thereby provide an uneven flame. y
A further object is provide a hydiocar bon burner of this classithat is simple in construction, reliable and etlicient `in operation and not expensive to manufacture.
Other and more speciiic objects will be apparent "from the following description taken in connection with the accompanying drawings, whereinv i Figure 1 is a view partly inside elevation and partly in vertical `section oi a hy,- drocarbonburner constructed in accordance with my invention;
. Fig. 2 isa plan view ot the same;
Fig. 8 is a sectional View substantially on a broken line 3, 3 of Fig. 1 g' Fig. 4 is an enlarged view in vertical cross section oiC the superheater taken` on line Fig. 5 is a view in horizontal cross-section substantially on broken line 5 5 oi Fig.4. i
Like reference numerals designate like parts throughout the several views.
Referring to the drawingspthe numeral G Adesignates a steam superheater, preferably a one piece metal casting of substantially rectangular shape, that has three longitudinally extending cylindrical passageways 7, 8 andA 9 arranged along the` two sides and in ther medial plane thereof, respectively, the
AVpassageways 7 and 8 being connected with eachother at one end by a cylindrical end passageway 10and thepassageways 8 and 9 being yconnectedwith eachother at the end by` ak cylindrical passageway 11. The p'assageways 81and 9" are connected with each other midway between the two ends by a transverse communicating passageway 12 while `the passageways 7 and 8 are separated trom each other at` the inlet end of the superheater by a partition wall 18 and the passageways 8 and l9 are separated Jfrom each other at the 'outlet end of the super- Vheater by a partition wall 14.
"Extending lengthwise between the ` passageways 7, 8 and 9 are two relatively thin, flat plate like portions with a plurality of peritorations 17, the plate lilre portion 16 being interrupted midway between its two ends by the transverse passagewayy 12 that interconnects the passageways 8 and 9.
The superheater is provided at one corner with a boss 18 that is perforated for the reception of a .steam inlet pipe and ,that communicates with the passageway 7 and such superheater isiprovided at the diagonally opposite corner and communicating with the passageway 9 with another boss`20 that is perforated for the reception of a steam outlet pipe: i
From the above description it will be obvious that the steam entering through the inlet 18 will follow the circuitous course indicated by the arrows through the passageways 7, 10, 8, 12 and 9 to the outlet 20 and will not ordinarily How throughvthose portions of the passageways 8 and 9 that lie beyond the passageway 12 and are connected by theend passageway 11, said passageway 11 and the adjacent end portions ot the passageways 8 and 9 constituting an expansion chamber that will lill `with steam vand tend to maintain a more nearly con stant pressure in the remainder of the superheater by receiving steam it the pressure within 'the superheater increases and giving out steam if the pressure within the superheater decreases. y
The inlet boss 18 of the superheater is connected by a pipe 21 with one end of a steam generator 22 that is preferably oblong cross-sectional shape, as shown in F ig. 8, and that is disposed below the superheater in parallel relation thereto. The. other end oi the steam genera-tor` 22 is connectedby a pipe 28 with a small receptacle 24 having a `vertical partition wall 25 `that terminates short of the top thereof and over which water must flow to reach the pipe 23.
The receptacle 24 is connected by a pipe 26 with the lower portion of a closed water regulator cup 27 which, in turn, is connected by a pipe 28 with a water supply tank 30, the pipe 28 having a valve 31 interposed 3 therein by which the flow of water through such pipe may be shut off if desired.`
The tank 30 isprovided with an opening in the top side to permit filling, the opening being arranged to be closed by a screw cap 32 in such a manner as to seal the tank and render the same air tight.
The water regulator cup 27 is further connected with a pipe 33 that extends upwardly alongside of the tank 30 and that has its top end bent'over as at 34, and projected into the upper portion of the tank 30 so that it will comn'iunicate with the space on the interior of such tank. The pipes 28 and 33 both proj ect downwardly into the water regulator cup 27 about half way to the bottom of such cup and terminate in yopen bottom ends disposed at substantially the elevation in the water regulator cup at which it is desired to maintain the water level.
The steam inlet 20 of the superheater is connected by `a pipe 35 with one end of a pipe 36 that forms a commingling or gas generating chamber `and that extends to the opposite end of the superheater and is thence doubled and extends rearwardly anl equal distance and is connected by an elbow memk ber 37 with a burner pipe 33 that is disposed lengthwise belowv the superheater in the medial plane thereof. rlhe pipe 36 is preferably inclined downwardly throughout its entire length so that fuel will flow freely to theburner pipe 38.
The burner pipe 38 is preferably of semicircular cross-sectional shape and is provided with one row of perforationsarranged toy direct gasilied fuel upwardly and with another row of perforations arranged to direct gasified fuel at an angle against the side of the steam generator 22.
The steam generating pipe 36 is connected at its inlet end with a fuel supply pipe 4A of liquid fuel, as kerosene oil, and that may have a valve Ll5 by which the flow of such fuel the generating pipes 36 may be controlled.
lf the tank 30` is filled with water and sealed andthe cock 3l is then opened water will enterthe regulator cup 27 and overflow into ythe rece tacle 24 and steam Generator 22 until it reaches a high enough level to just submerge the ends of the pipes 28 and 33 when by reason of the minus pressure in the upper end of the tank 3() such water will cease to flow until the ends of the pipes 28 and 33 are again uncovered thereby permitting air to enter the upper end of the tank 30 and water to flow into the regulator cup 27.
The partition 25 in the receptacle 24 prevents the water from falling only a short distance below the ends of the pipes 28 and 33 and prevents the water regulator cup 27 from being entirely emptied even if the water is all used out of the tank 30 thus insuring a constantv water seal between the tank 30 and the steam generator 36 at all times.
In the lighting of the burner, liquid oil is admitted to the pipes 36 and allowed to flow from the pipe 3S into the` pan ll where it is 85 ignited and allowed to burn to heat the burner pipes, superheater and steam generator. As soon as the several parts become sufficiently heated steam will be formed in the generator 22, and will be superheated in the'superheater 6 and will miX with the oil that enters the commingling chamber in the pipes 36 in which commingling chamber the oilV will be thoroughly gasified and mixed with the superheated steam sov that it will issue from the burner pipes as a highly volatile gas that will burn a hot blue flame that will be free from carbonand soot.
The foregoing description taken in con' nection with the accompanying drawings clearly disclose the form of construction and method of operation of my device, but, While l have illustrated and'described what l now consider to be the preferred embodiment of the invention it will be understood that the apparatus shown in the drawingsv is vmerely illustrativev and that such changes in form, dimensions and arrangement of parts may be resorted to as are within the scope of the following claim.
What l claim is: f
A steam superheater of the class described, comprising a rectangular body portion having three longitudinally arranged spaced apart steam passageways that are connected with each other at the ends to form a continuous conduit from one corner to the diagonally opposite corner of said body portion, said superheater having inlet and outlet means arranged at diagonally opposite corners respectively, and communicating with said passageways, and perforated plate sections extending lengthwise between saidpassageways and terminating short of the ends of said passageways the perforated plate section adjacent the outlet opening having a steam conduit extending erosswise thereof and inter-connecting two of said passageways to thereby permit steam to HOW by a shorter course to said outlet opening and to out off a portion of said passageways so that said cut off portion mayserve as an expansion chamber.
In Witness whereof7 hereunto subscribe my name.
