To all whom it may concern: 1

Be it known that I, RUssELL L. DAILEY, a citizen of the United States, residing at Kansas City, in the county of Wyandotte and State of Kansas, have invented certain new and useful Improvements in Steam-Generators, of which the following is a specification.

This invention relates to steam generators and particularly to that class of generators in which a liquid fuel vaporizer and burner are used in connection with one or more boiler or steam generating units.

One object of the invention is to produce a heater of high efiiciency located within a battery of steam boilers of a special type and from which steam is taken to atomize the liquid fuel as well as to maintain a forced draft through the vaporizing and heating compartments.

With this general object in View, the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and to afford a complete understanding of the same, reference will be made to the accompanying drawings, forming a part of this specification, and in which Figure 1 is a vertical section of the apparatus along the line II of Fig. 2; Fig. 2 is a plan view of the same, being partly in section along the line II-II of Fig. 1, and Fig. 3 is a broken perspective view of one of the vaporizing sections.

Referring to the drawings, the liquid fuel vaporizing portion of my apparatus is composed of a plurality of hollow vaporizing sections 2 arranged in superposed relation as shown. Each of these sections is of hemispherical form, and has an inlet opening 4 at the top and an outlet opening 6 at the bottom thereof. As the liquid enters the opening 4 it is received against an inclined baffle artition 8 and caused to pass entirely around the chamber within the section bya vertical partition 10 extending from one of the side walls almost entirely around the opening 6, leaving a passage 12 for entry of the liquid or fluid, and being cut away to provide another opening 14 for the fluid to pass out at-the opening 6. Each vaporizing section has upper and lower tubular extensions 16 and 18 for engaging in overlapping relation the corresponding extensions of the adjacent sections, suitable packing being inserted at these joints between the several ing vaporizin sections. One of the lower sections is provlded with a laterally projecting flange 22 to rest upon lu s 24 formed upon the adjacent portions 0 the generator or boiler sections 102 to form a support for the overlyspreader for t e flame from the burner.

Fltting upon the extension 18 of the lowermost vaporizing section 2 is a burner 26, which has a chamber 28 communicating with the adjacent opening 6 of the section 2. This burner is arch-shaped in cross-section, and has a plurality of discharge passages 30 through its outer wall for discharging the gas. The burner also has a transverse passage 32which communicates with an oil ipe 34 having a valve 36, the purpose of w ich is to supply the burner pan 38 below the burner 26 with an initial supply of oil when the apparatus is being first fired. The burner pan 38 is formed with a shallow annular trough 40 and a central vent opening 42,. and has an edge channel provided with packing 44 for engagement with a rib 46 depending from the base 48 of the apparatus, supports 50 of any suitable character being provided for said base. About the opening 42 is also formed a channel 52 to receive a flange rib 54 depending from a plate 56 supported over the opening by means of a screw 58, which is threaded through an extension 60 projecting into the middle of the opening. The lower end of the screw 58 is equipped with a hand-wheel 62 for convenience 1n operating the same. The plate 56, it will be understood, receives oil from the passage 32 and deflects it over into the trough 40 of the pan 38. While the charge in the pan is being burned, the opening 42 furnishes a draft until the forced draft (hereinafter referred to) is started, after which the opening 42 is closed by means of the-plate 56. The pan 38 is supported by means of buttons 66 secured by bolts 68 to lugs or projections 64 formed on the base 48.

A top or receiving chamber 7 0 is supported by the uppermost vaporizing section 2, over which top chamber is a top plate 72, forming the upper wall of the chamber, the interior of which is divided by a partition 74 into upper and lower compartments communicating through an opening 76 in said partition. The plate 72 is provided with a series of ears 78 to whichare secured, by nuts 82, the upper ends of a series of stay bolts 80. The lower ends of the bolts 80 are Patented Mar. 16, 1914.

sections, and also to act as a i bent at right angles to pass through a set of lugs 84 on the burner section 26, where they are held in place by cotters 86, whereby the burner and all the vaporizing sections itre held securely together in assembled reation.

Seated against a ring flange 88 formed around the margin of the base 48 is the lower edge of a drum casing 90, the upper Upon the base 48 is supported a series of boiler or steam generator units 102, of a number and size to generate the required pressure and volume of steam, fifteen of them being shown in the drawings. Each of these generators is provided with a series of inwardly projecting baffle partitions 104,

having upwardly and downwardly extend ing flanges 105 at their inner edges and forming a zigzag passage 106 through the generator chamber from top to bottom. The lower portion of the generator is provided with a vertical partition 108, to one side of which is thus formed a vertical chamber 110. The generator is reduced at about its middle portion to provide space for a steam collecting ring 112, which is connected to the generator by means of bolts 114 passing through the lower wall of the ring and ears 116 formed uponthe generator casing. The generator casing is likewise provided with ears 118 to which to secure bolts 119 to assist in retaining the top casting 92 in place.

The casting 92 has a passage 120 communicating with the upper end of the passage 106 of each boiler or generating unit 102, and also through a port 121 with the water supply chamber 94. This port 121 is controlled by a valve comprising a screw rod 122 having a tapered end adapted to seat in said port.

The steam collecting ring 112 has a re ceiving opening overlyin the chamber 110 of .each generator, a disc arge port 123 extending from the upper end of said chamber into the steam ring, packing 124 being placed about each of these joints. At the base of each chamber 110 is a drain cock 125, extending outside the drum 90.

For taking the steam away from the steam collecting ring 112 at suitable points, spaced a art as often as required (five being 3 own), are receiving pipes 126, which open into the upper walls of said ring and conduct the steam away to one or more points, as desired. A pipe 128 is also in communication with one of said pipes 126, and leads to a steam pressure gage 130.

For supplying oil to the vaporizing apparatus, a pipe 132 passes from a source of supply (not shown) through the dome 100 to a T 134, from which a pipe 136 extends through the top plate 72 and the opening 76 into the lower compartment of the receiving chamber 70. The T 134 carries .a nozzle 138 projecting into the pipe 136, this nozzle being for the purpose of receiving steam through a pipe 140 from one of the steam pipes 126 and discharging said steam into the pipe 136, thereby atomlzing the oil while it passes through the latter pipe into the top receiving chamber. The lower end of the pipe 136 is fitted with a baffle or splash plate 142 for receiving and deflecting the oil spray toward the sides of the top receiving chamber.

In order to furnlsh a draft through the apparatus after the same has been set in operation by means of the oil burned in the pan 38, air is supplied through an opening 144 in the top portion of the receiving cham ber by pipes 146 at suitable points (five being shown). These pipes havea down- \vard bend and pass through openings in the top casting 92, and have their lower ends fitted with mixers 148 which pass through the sides of the drum casing 90. These mixers may be regulated by screw operated caps 150, and are closed during the initial burning of the oil in the pan 38. Connected with the pipes 146 in line with the openings 144 are pipes 152 communicating with the steam plpes 126, whereby steam may be forced into the air supply pipes for furnishing a forced draft sufiicient to meet the needs of the apparatus. i

The operation of the apparatus will be readily understood from the foregoing without an extended explanation, but briefly summarized it is as follows: The liquid fuel is allowed to flow into the pan 38 to fill the trough 40, the plate 56 being raised to allow air to enter the opening 42. By burning this charge of oil, the burner and vaporizing sections are heated sufliciently to start the vaporizing action, whereupon oil is admitted through the pipe 132 into the top receiving chamber, from where it passes successively through the vaporizing sections. The winding, tortuous passage through these sections insures that the fuel will be completely vaporized by the time it reaches the burner below. Moreover, after steam has begun to be generated, the flow of the steam through the nozzle 138 into the pipe 136 thoroughly breaks up the. oil as. it enters the top receiving chamber, thereby accelerating the vaporizing action. It will be noted that the bottom ofeach section 2 slopes outward so that any oil therein will be directed against the outer wall of the section. The steam generator units are spaced about the vaporizing and burner sections, and when the heating action is Well under way, the flames and hot fumes completely envelop all the parts of the apparatus inside the drum. As water is admitted to each generator section, it is obliged to follow the zigzag course through the passage 106, whereby an extended heating surface is presented to the water which will be converted into steam before it reaches the chamber 110. The upwardly projecting flanges 105 obstruct the flow of the water and act to retain the same upon the upper baflies 104. The steam is collected from these chambers 110 into the steam ring 112, and from there lead oif through the pipes 126. The draft through the apparatus is controlled by the mixers 148, and to insure a suliicient air supply through the pipes 146, steam is conducted thereto through the pipes 152. v

From the above description it will be apparent that I have produced an eflicient apparatus for carrying out the object of my invention, which apparatus might obviously be employed for hot water heating or analogous uses, and while I have illustrated and described the preferred embodiment thereof, it is to be understood that it may be moditied in form, proportion, detail construction and organization Without departing from the principle of construction as defined in the appended claims.
