- Fig. 2 is a front elevaheated, thereby producing a gas possessing tion, looking in the direction of the arrow the necessary qualities for heating or illumishown in Fig. 1,the furnace being shown only nating, as may be desired.
- the purposes for in outline and portions of the Vaporizers, 0011- which the gas is intended will govern to some necting-pipes,retor'ts,&c.,being shownin secextent the amount of the gas formed from 0 tion.
- Fig. 3 is a vertical section on the line steam employed in the process.
- Fig. at is a horizontal longen, and the heat and light giving qualities 5 gitudinal section of the furnace on the line of the gas may be-regulated in this manner by Y Y of Fig. 1.
- Fig. 5 is a longitudinal vertisimply increasing or diminishing the amount cal section of Figs. 3 and 4: on the line Z Z, of the steam product employed in its manuone of the Vaporizers being shown in dotted facture.
- A, Fig. 1 designates a device for heating hydrocarbons, which consists of a casing closed at the top and bottom, provided with a steam-coil 1, through which steam from any source is passed, both the inlet and outlet thereof being controlled by suitable valves of ordinary construction.
- Hydrocarbon is conducted to the heater by means of a pipe 2, filling all the space not occupied by the steam-coil 1.
- the hydrocarbon is taken from a storage-tank situated above the heater, and this tank, being kept filled at a uniform height by means of an automatic valve of well-known construction, allows a steady and equal pressure of the liquid flowing into' the heater.
- the hydrocarbon thus brought into contact with the steam-coil is raised to a degree of heat which materially assists in its vaporization, and the temperature of the hydrocarbon in the heater can be shown at all times by placing a thermometer at some convenient point, as at3.
- the hydrocarbon,being thus heated, is conducted through a pipe 4 and regulating-valve 5 through a sight-glass 6, which enables the operator to see at all times the flow therethrough and assists in detecting instantly any irregularity in the feed, and then passes into the vaporizer B through the pipe 6'. 4
- the object of the vaporizer B is to vaporize the hydrocarbon rapidly,- perfectly, and with the greatest economy. It consists of a cylindrical pipe or casing 7, inclosing a pipe or casing 8, the outer casingbeing closed and the inner one open at the top and bottom.
- the smaller or inclosed pipe or casing 8 is so arranged as to serve as an escape-flue for a short distance of the heated gases orproducts of combustion in such a manner as to make a large portion of the heat of such gases or escaping products of combustion available for the purpose of vaporizing the hydrocarbons.
- the chamber between the outer and inner casings or pipes near the top and preferably against the surface of the inner pipeor casing 8 are more or less fully vaporized, according to the degree of heat attained by such pipe.
- this pipe is creased or grooved spirally from top to bottom, and in this groove is wound or coiled a pipe 9, preferably of copper or iron, which fits snugly within the said groove, sinking about half
- superheated steam taken, preferably, from steam-pipes arranged within the furnace, as hereinafter described.
- This super-heated steam may be caused to enter the Hydrocarbons being admitted into coiled pipe 9 at the top by means of pipes 10, as shown in Fig. 2, or it may, if preferred, be introduced at the bottom by means of pipes 11, as shown in dotted lines in said Fig. 2.
- Thehydrocarbonin a heated condition passes into the vaporizer at the top, as shown, and,
- Vaporizers in which three Vaporizers are employed in connection with one furnace, after passing around the end of the upper branch of the retort C, unite and pass through a small orcentral vaporizer E, which in internal construction is identical with that of the large Vaporizers B, it having a central pipe or fine 8 grooved and covered with conical projections and having a steam-pipe 9 wound or coiled around it, through which superheated steam is passed and against all of which hydrocarbon is thrown for the purpose of vaporization, as hereinbefore described.
- the vapor formed in the central vaporizer E passes through pipes 16, as shown in Fig. 2, which communicate with the pipes 13,which convey the vapor from the large Vaporizers, and thus all the vapor formed from the several Vaporizers is admitted to the upper branch 0 of the retort. which passes through the inner pipe 8 of the central vaporizer necessarily throws off a.
- Figs. 1, 2, and 3 we have shown the system of pipes by which steam is superheated and used in the process of vaporization, and in Fig. 6 the means by which steam, after being converted into a fixed gas, is mingled with the fixed gas formed from the hydrocarbon and a resultant fixed gas composed of these two products produced.
- Fig. 1 shows a system of these pipes for superheatingthe steam after it comes from the generator. These pipes are arranged longitudinally on the braces which support the separate branches of the retort.
- They preferably consist of separate coils arranged on each side of the retort, and from one coil is taken superheated steam for one of the large Vaporizers and for the central or small vaporizer and from the other superheated steam for the other large vaporizer. As shown, steam enters these coils at 17, Fig. 2, and emerges at 18, and is c011- ducted thence by pipes 10 to the top of one of the large Vaporizers B and to the central vaporizer E.
- the braces 18' for sustaining and holding in place the retort and steam-pipes within the furnace may be constructed in any desired manner; but we prefer to have them set in the brick-work when the furnace is built and so arranged that the retort and steam-pipes may be put in after the brick-Work is finished or removed at any time without disturbing the same or injuring the retort or pipes.
- the position and construction of these braces is shown in Fig.
- the central openings being designed to receive the separate branches 0 and D of the retort, the end couplings of the steam-coils being shown at 19, and the entrance and exit ends of the same being shown as immediately above and below said coupthrough the retort and compelling it to pass in contact with the heated walls or surfaces thereof, and also the means for mingling superheated steam or a fixed gas formed therefrom withthe gas formed from hydrocarbon.
- the first consist of segmental diaphragms or plates 21, which are preferably of such shape and size as to occupy the greater portion of the area of the retorts in cross-section, arranged alternately, as shown, and held in position by any means desired, but preferably by being placed or strung upon a rod 22, as shown.
- the obj ectof this construction is to retard the flow of the gas through the retort and to compel it to pass in contact with the walls of the retort in order that it may be heated to the required degree.
- These diaphragms or plates are preferably arranged in the upper branch of the retort, or the one into which the vaporfirst enters; or,if more than two branches be employed or the retort be composed of a series of tubes, as shown in Figs. 7and 8, they may be arranged in all the tubes or branches thereof except the last, or the one from which the gas leaves the retort.
- the means for mingling the gas formed from hydrocarbons with that formed from steam are arranged in the return or lower branch of the retort, and consist of a tuhe23, preferably of copper, placed within the branch D of the retort and flanged or enlarged at the inner end, so as to fit tightly theinner wall of the retort, thus compelling the gas to pass through the inner tube.
- This pipe or tube 23, as shown, does not extend the entire length of the retort. ⁇ Vithin the annular space between the inner walls of the retort and the inner tube 23 is placed a steam-pipe 24.
- This pipe enters the retort, preferably at or near the outer end, and runs back to a point at or near the junction of the pipe 23 with the retort.
- the inner end of the pipe 24 is left open, and steam, preferably from the superheated coils within the furnace, is admitted at some convenient point, as 25, and escapes from the inner open end of the pipe and surrounds the tube 23.
- This steam being superheated to a high degree, is decomposed.
- the product is a fixed gas, and the constituent elements thereof, largely hydrogen, unite with the fixed gas passing through tube 23, formed from hydrocarbons, at the open end of said tube, and a fixed gas of greater body and heat-giving power than that produced'from either hydrocarbons or steam separately is produced.
- retort instead of forming the retort with but two branches, as hereinbefore described, we may employ a number of branches or coils, as shown in Figs. 7 and 8, the former being a transverse section showing, the plan of the arrangement of the separate branches or coils of the retort. In this case, however, the means for mixing the gases formed from hydrocarbons and steam should be located in the return branch D, as hereinbefore described.
- Fig. 3 shows an opening, which extends from front to rear of the furnace, the form of the lower part thereof in cross-section being shown in full lines and that of the upper portion partly in full and partly in dotted lines.
- the upper and lower parts of this opening are designated by the letters G and H, respectively, and in the upper openingG are placed the retort and superheatin g steam-pipes, hereinbefore described, the burners or heating apparatus being located in the lower division or part H of the combustion-chamber.
- This opening is closed, preferably, with iron plates backed with brick after the walls are all built, and the pipes, retorts, burners, 6270., put in position.
- TheupperpartG isprovidedattherear withadoor through which the steam-pipes may be removed or other repairs made, and the lower part is also preferably provided at the rear with a sight-opening and means for admitting air, if air berequired.
- the burnersextend when in position, from one end of the chamber H to the other and preferably almost to the top thereof.
- the flames rising in the chamber G impinge on all the pipes therein, and the contraction of the side walls near the upper part of chamber G, as shown in dotted lines in Fig. 3, compel the flames'and heated gases of combustion to strike the upper pipe of the retort and the upper coils of the steampipes,thus keeping both the upper and lower pipes equally hot.
- Small diving-flues 26 are constructed at intervals along the side walls near the top of chamber G, which carry the products of combustion into flues 27, arranged longitudinally in either side wall, and these fines return at the rear, as shown at Fig. 5, and pass forward, downward, and upward through the vaporizer B and pipes 28 to the chimney.
- the flues 29,with which the flues 27 communicate, connect directly with the chimney, and by opening dampers 30 and 31 (see Figs. 1 and 5) the escaping products of combustion will pass directly through flue 29 into the chimney; or by closing damper 31 and leaving 30 open the draft will pass through both branches of the fine 27 and up through flue 29 to the chimney.
- damper 30 By closing damper 30 the draft is compelled to pass through the lower part of flue 29 and the lower return portion of fine 27 and up through the Vaporizers B to the chimney, and by closing both of the dampers 30 and 31 the draft is compelled to pass through the entire length .of fine 27 and up through the Vaporizers B into the chimney.
- Fig. 5 is shown the air-supply flue, by means of which air is heated to aid in combustion, this flue being similar in form to fine 27, passing downward and forward, as shown.
- One of these flues is arranged on each side of the furnace and entirely inclosed in the side walls thereof. The air is admitted at 33 through the side wall of the furnace, and,
- openings or perforations 3i are preferably formed by perforating the bricks, and these bricks, becoming highly heated, also aid in heating the air to a high degree.
- This hot air enters the chamber 11, preferably at a point just above the burners, as shown at 34, Fig. 3, and immediately unites with the burning gases.
- the amount of air admitted to the air-flue may be regulated at 33 in any desired manner.
- the cost of vaporizingthe hydrocarbon is reduced to a minimum, as the heat required to keep the retort in proper condition for fixing I t t vaporizer, thus making the gas is sufficient to super-heat; the steam necessaryin the process of vaporization, and the escaping products of combustion also matcrially aid therein, the heat therefrom being otherwise thrown away.
- the hot gas is cooled somewhat by yielding its heat to the central this vaporizer doubly beneficial.

for producing gas from hydrocarbon alone and then the modification of such apparatus by which the gas is produced from hydrocarbon and water or steam.
Referring to the drawingsand the reference letters and numerals thereon, A, Fig. 1, designates a device for heating hydrocarbons, which consists of a casing closed at the top and bottom, provided with a steam-coil 1, through which steam from any source is passed, both the inlet and outlet thereof being controlled by suitable valves of ordinary construction. Hydrocarbon is conducted to the heater by means of a pipe 2, filling all the space not occupied by the steam-coil 1. The hydrocarbon is taken from a storage-tank situated above the heater, and this tank, being kept filled at a uniform height by means of an automatic valve of well-known construction, allows a steady and equal pressure of the liquid flowing into' the heater. The hydrocarbon thus brought into contact with the steam-coil is raised to a degree of heat which materially assists in its vaporization, and the temperature of the hydrocarbon in the heater can be shown at all times by placing a thermometer at some convenient point, as at3. The hydrocarbon,being thus heated,is conducted through a pipe 4 and regulating-valve 5 through a sight-glass 6, which enables the operator to see at all times the flow therethrough and assists in detecting instantly any irregularity in the feed, and then passes into the vaporizer B through the pipe 6'. 4
The object of the vaporizer B is to vaporize the hydrocarbon rapidly,- perfectly, and with the greatest economy. It consists of a cylindrical pipe or casing 7, inclosing a pipe or casing 8, the outer casingbeing closed and the inner one open at the top and bottom. The smaller or inclosed pipe or casing 8 is so arranged as to serve as an escape-flue for a short distance of the heated gases orproducts of combustion in such a manner as to make a large portion of the heat of such gases or escaping products of combustion available for the purpose of vaporizing the hydrocarbons. the chamber between the outer and inner casings or pipes near the top and preferably against the surface of the inner pipeor casing 8 are more or less fully vaporized, according to the degree of heat attained by such pipe. To increase this heat and radiate it as much as possible, conical projections are cast or otherwise formed on the surface of this pipe 8, and to still further assist in the process of vaporization this pipe is creased or grooved spirally from top to bottom, and in this groove is wound or coiled a pipe 9, preferably of copper or iron, which fits snugly within the said groove, sinking about half Through this pipe 9 is passed superheated steam taken, preferably, from steam-pipes arranged within the furnace, as hereinafter described. This super-heated steam may be caused to enter the Hydrocarbons being admitted into coiled pipe 9 at the top by means of pipes 10, as shown in Fig. 2, or it may, if preferred, be introduced at the bottom by means of pipes 11, as shown in dotted lines in said Fig. 2. Thehydrocarbonin a heated condition passes into the vaporizer at the top, as shown, and,
impinging upon the surface of the inner pipe 8, strikes the steam-coil 9 and follows around it, traversing the whole length thereof from top to bottom. If from any cause particles of hydrocarbon leave the coil and drop, they are at once caught either on the surface of or the projections on the pipe 8 or on the lower coils of the pipe 9, and the result is to vaporize all or nearly all of the hydrocarbon beforeit reaches the bottom of the chamber. If for any reason a portion of the hydrocarbon is not vaporized, it is allowed to run off through a pipe 12 at the bottom of the vapor izer, and thence to a seal, where it is caught and saved for future use. As fast as vapor is formed itis allowed to escape through a pipe 13, which communicateswith the vaporizer, as shown in Figs. 1 and 2, by which it is conveyed into one branch 0 of a retort located within the-furnace, and, passing through this branch of the retort and returning through the return branch D, each of said branches being heated to a high degree, it is converted into a fixed gas and emerges from the return branch of the retort D through the pipes 14 and l5. as shown in Fig. 2. These pipes 14 and 15 in the form of apparatus illustrated. in which three Vaporizers are employed in connection with one furnace, after passing around the end of the upper branch of the retort C, unite and pass through a small orcentral vaporizer E, which in internal construction is identical with that of the large Vaporizers B, it having a central pipe or fine 8 grooved and covered with conical projections and having a steam-pipe 9 wound or coiled around it, through which superheated steam is passed and against all of which hydrocarbon is thrown for the purpose of vaporization, as hereinbefore described.
The vapor formed in the central vaporizer E passes through pipes 16, as shown in Fig. 2, which communicate with the pipes 13,which convey the vapor from the large Vaporizers, and thus all the vapor formed from the several Vaporizers is admitted to the upper branch 0 of the retort. which passes through the inner pipe 8 of the central vaporizer necessarily throws off a.
large amount of heat, which is utilized, as shown, for vaporizing hydrocarbons, exactly as the escaping products of combustion are utilized in the main Vaporizers B. It will be seen that all the gas formed from the hydrocarbon or from hydrocarbon and steam, as hereinafter described, by the-apparatus illustrated passes through the inner pipe 8 of the central vaporizer. It is then cooled to the required degree, if necessary, by any of the well-known methods, after which it is reduced to the required candle-power by the IOC IIO
admission of atmospheric air and is conveyed into a gas-holder in the usual manner by an exhauster such as in ordinary use.
In Figs. 1, 2, and 3 we have shown the system of pipes by which steam is superheated and used in the process of vaporization, and in Fig. 6 the means by which steam, after being converted into a fixed gas, is mingled with the fixed gas formed from the hydrocarbon and a resultant fixed gas composed of these two products produced. Fig. 1 shows a system of these pipes for superheatingthe steam after it comes from the generator. These pipes are arranged longitudinally on the braces which support the separate branches of the retort. They preferably consist of separate coils arranged on each side of the retort, and from one coil is taken superheated steam for one of the large Vaporizers and for the central or small vaporizer and from the other superheated steam for the other large vaporizer. As shown, steam enters these coils at 17, Fig. 2, and emerges at 18, and is c011- ducted thence by pipes 10 to the top of one of the large Vaporizers B and to the central vaporizer E. After passing through these Vaporizers it again enters the superheatingcoils at 17 and emerges at 18', from which point it passes to the other large vaporizer through the pipe 10, and is then preferably conducted to a water-heater and utilized for the purpose of heating water before it is supplied to the boiler, and thus the same steam is used over and over again, thus greatly economizing in the amount of fresh steam taken from the boiler.
It is evident that the exact arrangement of pipes above described need not be followed closely in practice, as in some instances it might probably be preferable to connect the steam-supply with the bottom of the vaporizers by means ofpipes 11, as shown in dotted lines, and we do not limit ourselves to any arrangement of these pipes other than such a form thereof as will conduct the superheated steam from the coils within the furnaces through the coils 9, arranged within the vaporizers, for the purposes set forth herein. It is also evident that we maylimit ourselves to a single vaporizer in connection with the retort or increase the number beyond that here in described and shown Without departing from the scope of our invention, the arrangement of steam-pipes and other details ofconstruction being such in all cases as may be rendered necessary by the number of vaporizers employed.
The braces 18' for sustaining and holding in place the retort and steam-pipes within the furnace may be constructed in any desired manner; but we prefer to have them set in the brick-work when the furnace is built and so arranged that the retort and steam-pipes may be put in after the brick-Work is finished or removed at any time without disturbing the same or injuring the retort or pipes. The position and construction of these braces is shown in Fig. 3, the central openings being designed to receive the separate branches 0 and D of the retort, the end couplings of the steam-coils being shown at 19, and the entrance and exit ends of the same being shown as immediately above and below said coupthrough the retort and compelling it to pass in contact with the heated walls or surfaces thereof, and also the means for mingling superheated steam or a fixed gas formed therefrom withthe gas formed from hydrocarbon. The first consist of segmental diaphragms or plates 21, which are preferably of such shape and size as to occupy the greater portion of the area of the retorts in cross-section, arranged alternately, as shown, and held in position by any means desired, but preferably by being placed or strung upon a rod 22, as shown. The obj ectof this construction is to retard the flow of the gas through the retort and to compel it to pass in contact with the walls of the retort in order that it may be heated to the required degree. These diaphragms or plates are preferably arranged in the upper branch of the retort, or the one into which the vaporfirst enters; or,if more than two branches be employed or the retort be composed of a series of tubes, as shown in Figs. 7and 8, they may be arranged in all the tubes or branches thereof except the last, or the one from which the gas leaves the retort.
The means for mingling the gas formed from hydrocarbons with that formed from steam are arranged in the return or lower branch of the retort, and consist of a tuhe23, preferably of copper, placed within the branch D of the retort and flanged or enlarged at the inner end, so as to fit tightly theinner wall of the retort, thus compelling the gas to pass through the inner tube. This pipe or tube 23, as shown, does not extend the entire length of the retort. \Vithin the annular space between the inner walls of the retort and the inner tube 23 is placed a steam-pipe 24. This pipe enters the retort, preferably at or near the outer end, and runs back to a point at or near the junction of the pipe 23 with the retort. The inner end of the pipe 24 is left open, and steam, preferably from the superheated coils within the furnace, is admitted at some convenient point, as 25, and escapes from the inner open end of the pipe and surrounds the tube 23. This steam, being superheated to a high degree, is decomposed. The product is a fixed gas, and the constituent elements thereof, largely hydrogen, unite with the fixed gas passing through tube 23, formed from hydrocarbons, at the open end of said tube, and a fixed gas of greater body and heat-giving power than that produced'from either hydrocarbons or steam separately is produced. A result to some extent similar may be produced without the employment of tube 23; but we prefer the method of construction herein described and illustrated. By this construction the vapor from the hydrocarbons is kept separate from that of the steam till both are decomposed and formed into fixed gases, and this requisite in order to produce a perfect fixed gas by a combination of these substances.
Instead of forming the retort with but two branches, as hereinbefore described, we may employ a number of branches or coils, as shown in Figs. 7 and 8, the former being a transverse section showing, the plan of the arrangement of the separate branches or coils of the retort. In this case, however, the means for mixing the gases formed from hydrocarbons and steam should be located in the return branch D, as hereinbefore described.
We come now to the description of the furnace, sectional views of which are given in Figs. 3, 4, and 5.
Fig. 3 shows an opening, which extends from front to rear of the furnace, the form of the lower part thereof in cross-section being shown in full lines and that of the upper portion partly in full and partly in dotted lines. The upper and lower parts of this opening are designated by the letters G and H, respectively, and in the upper openingG are placed the retort and superheatin g steam-pipes, hereinbefore described, the burners or heating apparatus being located in the lower division or part H of the combustion-chamber. This opening is closed, preferably, with iron plates backed with brick after the walls are all built, and the pipes, retorts, burners, 6270., put in position. TheupperpartGisprovidedattherear withadoor through which the steam-pipes may be removed or other repairs made, and the lower part is also preferably provided at the rear with a sight-opening and means for admitting air, if air berequired. The burnersextend, when in position, from one end of the chamber H to the other and preferably almost to the top thereof. The flames rising in the chamber G impinge on all the pipes therein, and the contraction of the side walls near the upper part of chamber G, as shown in dotted lines in Fig. 3, compel the flames'and heated gases of combustion to strike the upper pipe of the retort and the upper coils of the steampipes,thus keeping both the upper and lower pipes equally hot. Small diving-flues 26 are constructed at intervals along the side walls near the top of chamber G, which carry the products of combustion into flues 27, arranged longitudinally in either side wall, and these fines return at the rear, as shown at Fig. 5, and pass forward, downward, and upward through the vaporizer B and pipes 28 to the chimney. The flues 29,with which the flues 27 communicate, connect directly with the chimney, and by opening dampers 30 and 31 (see Figs. 1 and 5) the escaping products of combustion will pass directly through flue 29 into the chimney; or by closing damper 31 and leaving 30 open the draft will pass through both branches of the fine 27 and up through flue 29 to the chimney. By closing damper 30 the draft is compelled to pass through the lower part of flue 29 and the lower return portion of fine 27 and up through the Vaporizers B to the chimney, and by closing both of the dampers 30 and 31 the draft is compelled to pass through the entire length .of fine 27 and up through the Vaporizers B into the chimney.
In Fig. 5 is shown the air-supply flue, by means of which air is heated to aid in combustion, this flue being similar in form to fine 27, passing downward and forward, as shown. One of these flues is arranged on each side of the furnace and entirely inclosed in the side walls thereof. The air is admitted at 33 through the side wall of the furnace, and,
.passing backward, as indicated by the arrows, returns through the lower branch of the fine and enters the fire-box or combustionchamber through small openings or perforations 3i. These openings are preferably formed by perforating the bricks, and these bricks, becoming highly heated, also aid in heating the air to a high degree. This hot air enters the chamber 11, preferably at a point just above the burners, as shown at 34, Fig. 3, and immediately unites with the burning gases. The amount of air admitted to the air-flue may be regulated at 33 in any desired manner.
Instead of the flue 32 for heating the air to aid in combustion, we may employ a single chamber, to which air may be admitted and heated before entering the combustion-chamber, and many other changes in the construction and combinations of the various portions of the apparatus herein described may be made without departing from the scope of our invention; but one pipe would be sufficient to connect the retort with the central tube of the central vaporizer, (shown in Fig. 2,) and it is possible to convert the hydrocarbon'into vapor in the Vaporizers B by means of superheated steam alone, the coil 9 being so arranged as to accomplish this object withouttheaid of the escaping products of combustion.
The advantages gained by this apparatus for producing a fixed gas from hydrocarbons or from hydrocarbons and steam are many. By putting all the hydrocarbon into the retort in the form of a vapor the possibility of coking in the retort from any cause is absolutely avoided. The amount of hydrocarbon converted into a fixed gas in a given time is materially increased, since the work of fixing the gas is half accomplished before the vapor is admitted into the retort. The cost of vaporizingthe hydrocarbon is reduced to a minimum, as the heat required to keep the retort in proper condition for fixing I t t vaporizer, thus making the gas is sufficient to super-heat; the steam necessaryin the process of vaporization, and the escaping products of combustion also matcrially aid therein, the heat therefrom being otherwise thrown away. i The hot gas is cooled somewhat by yielding its heat to the central this vaporizer doubly beneficial.
