heat the retort or vaporizer, to adapt a burnerv UNITED STATES PATENT OFFICE.
SPECIFICATION forming part of Letters Patent No. 477,872, dated June 28, 1892.
Application filed May 17, 1889. Renewed December 5, 1891. Serial No. 414.191. (No model.)
izer and burner adapted for the vaporizing and burning of crude petroleum or other bydrocarbon oils; and among the objects in View are to provide a vaporizer and burner of the class described adapted to generate the greatest amount of heat from the least amount of oil and to combine with this vapor air, thereby increasing the heat, and deliver the same in such a manner as to secure the full benefit of its heat and to thoroughly thus constructed for connection with asteamboiler and in such a manner as to secure the full draft of the boiler, to so arrange the burner as to deliver the flame directly into the fines of the boiler, and to provide ameans for carrying off the oil-tar from the vaporizer or retort and delivering the same, and, further, to so locate the mixing-chamber as to prevent the same from becoming unduly heated or heated to that extent as to form carbon in its valve-chamber, and thus destroy the discharge of vapor into the mixing-chamber.
The invention consists in certain features of construction hereinafter specified, and particularly pointed out in the claims.
Referring to the drawings, Figure 1 is a central vertical section of that class of boilers known as fire-tubes or tubular boilers provided with a burner arranged in j uxtaposition and constructed in accordance with my invention. Fig. 2 is an end elevation of the same. Fig. 3 is a horizontal longitudinal section on line or m, Fig. 2, of the mixingchamber and the retort or vaporizer, the parts being shown enlarged. Fig. 4 is a front elevation of the retort or vaporizer in detail. Fig. 5 is a rear elevation of the same and its connecting-pipes, and Fig. 6 is a detail in section of the lower portion of the tar-pipe and its valve.
Like numerals of reference indicate like parts in all the figures of the drawings.
I have herein shown my invention as apinvention is equally applicable to other types of boilers, the same being accomplished either by the same arrangement, hereinafter described, or such slight changes as may suggest themselves to any ordinary mechanic or other person skilled in the art to which my invention appertains.
1 represents a boiler; 2, the diaphragm; 3, the fire-tubes; 4, the fire-box; 5, the grate; 6, the ash-pit, and 7, a door, which may be of the ordinary fuel-poke or especially-constructed door, as described. 4 Referring more particularly to Figs. 1 and 3, 8 represents the mixing-chamber, which is of cylindrical form and having the open discharge end 9, near the end of which is located an annular ring or diaphragm 10. The rear end of the mixing-chamber 8 is conical in form and provided with openings 11 and terminates in a screw-threaded boss 12, having I an interior conicalshaped valve-seat 13, communicating with the interior of the chamber. 14 represents a valve-chamber provided with a valve-stem 15, screw-threaded therein, the needle end 16 of which is adapted to operate in the seat 13, all as clearly shown in Fig. 3. This completes the burner, and the same is inserted in an opening 17, formed in about the center of the door 7 of the boiler and projected through said door merely sufficiently far to deliver the vapor into the boiler, whereby about half of the chamber and its entire valve and adjuncts are located outside of the boiler Where they may be controlled by the operator. in the door 7 and serve to deliver an annular draft of airaround the burner 8 to com mingle with the vapor after the same has left the burner. The openings 11 in'the chamber 8 furnish sufficient air for a proper com mingling with the vapor before emission.
Referring more particularly to Figs. 1, 4, and 5, 19 represents the retort or vaporizer, which is located within the fire-box 4 of the boiler and in line with the mixing-chamber. The retort or vaporizerconsists of a front plate 20, having annnlarly-formed opposite walls 21, which form an annular chamber 22. At the center of the retort is formed a concave cap 23, maintained in position by means of hollow Openings 18 are also provided ICO arms 24, diametrically oppositeand connecting the caps and annular chamber 22. A nipple 25 is formed at the center of the front plate 20 of the retort, and screw-threaded to the same is an elbow-coupling 26, to which is connected the oil-supply pipe 27, which extends through the' end wall of the boiler, is provided with a cut-off 28, and communicates with the reservoir 29.
30 represents the vapor-pipe, which communicates with the annular passage 22 and leads from thence at its upper portion down to the fire-box through the end of the boiler and into the valve-chamber 14:, where it supplies vapor through the valve 13 to the chamber 8 and is there mixed with air.
From the lower portion of the annular recess 22 of the retort 19 there extends a depending pipe 31, which passes out through the end of the boiler and is provided'at its end with a weightedvalve 32, and under the pipe is arranged a receptacle 33. The pipe 31 is intended to carry off the tar which is the residuum from the oil after vaporization and deposit the same in the receptacle 33, thus preventing the clogging of the retort.
The operation of my invention will beatonce apparent and may be briefly stated as follows: To start the fire, a small preliminary fire is kindled upon the grate 5 for the purpose of heating the retort 19, or, if desired, a lamp for this purpose may be employed. The cut-oft 28 is opened-and oil supplied from the reservoir 29 through the pipe 27 and delivered into the conical cap 23 and distributed at'ter vaporization through the arms 24 into the annular recess 22. The natural expansion of the vapor causes the same to rise to the upper portion of therecess 22, and is conducted oh? by the pipe 30 to the valve 14 and by the valve-stem is emitted into the mixing-chamber in regulated quantities, in which chamber it is thoroughly commingled with the air which is drawn in by the suction of the vapor through the openings 11, and is then discharged through the opening 9, where it is further mixed with air and gets the fulltorce of the draft of the boiler and is discharged against the heated retort 19, by which the retort is maintained heated and a constant vaporization of oil takes place. The flame caused by the vapor coming in contact with the retort is discharged in a volume from around the retort and also through opposite semi-annular openings 34:, formed in the retort around the cap 33, and is passed through the fire tubes or fines and thoroughly heats the water in the boiler.
Having thus described my invention, What I claim is 1. The combination, with the fire-box of a boiler, of a mixing chamber and burner mounted in the end wall thereof, a retort having a continuous circular passage, a central concave cap, and a transverse chamber communicating with the circular passage, mounted in the box in line with the chamber, a supply-pipe communicating with the cap, a vapor-pipe communicating with the circular passage and with a valve-chamber mounted on the mixing-chamber, and a tar-pipe leading from the lower end of the circular passage, substantially as specified.
2. The combination, with the fire-box 4, having the door 7, perforated at 17 and 18, of a mixing-chamber 8, mounted in the perforation 17 and having the open end 9, the perforated conical end 11, the intermediate perforated diaphragm 10, and terminating in the valve-seat portion 13, exteriorly screw-thread ed, as at 12, the valve-chamber 14:, mounted on the threads and carrying valve-stem 15 and valve 16, the retort 19, mounted in line with the chamber 8 within the boiler and having the annular passage 22, cap 23, inter-.
