To all whomtt mag concern: I Be it known that ll Chauncey B.Foawere, citizen of the nited States, residing at Urbana, in the county of Champaign and State of Ohio, have invented certain new and useful Improvements in Apparatusfor vaporizing Hydrocarbon Oils, of which the following s a specificatmn. f

This invention relates to an apparatus for vaporizing hydro-carbon oils, all subticularly pointed out in the claims.

In the accompanying drawings, vFigure 1 is a vertical longitudinal sectional elevation of the apparatus, and Fig. 2 is a sectional plan on line 22, Fig. 1. Fig. 3 is a cross section substantially on line 3-3, F1g. 1,

and Fig. 4 is a front elevation of the complete installation. 4

The conception herein embraces-the apparatus more or less asa whole and details of fllene may be derived from the vaporized product in such subsequent treatment as may be had by condenser or otherwise.

As herein shown A represents the wall of the furnace and a, b and 0 the vaporizing sections or parts of the retort proper. The said sections or portions are each double, in a sense, as there is an inner tube or pipe 2 for-the oil and an outer tube or pipe 3 forming a jacket about the same for superheated steam. These sections and the inclosing wall of the furnace may have any suitable length, say twenty feet, more or less,.and the said sections are set at such inclination in respect to each other as to provide continuous drain or flow by gravity of any possible unvaporized substances through the same.

The said sections also are continuous one with the other from a tob and b to 0 by means of elbows or joints d and d at their ends, but the said elbows or joints are exspecification of Letters Patent.

steam jackets 3 as seen more especially in charging at 5 at the rear of. the retort.

From this point the vapors are taken off for subsequent treatment in condensers or The said elbows also are removable so as to-make it possibleto reach and remove any one of the pipes 2'without disturbing other parts. 1

llt will be noticed that the outer or jacket pipes 3. of the said sections terminate substantially at the wall of the furnace, and

have annular flanges or rings 6 just outside said wall at their ends which are bolted to a collar S'sleeved on oil pipe 2, and which collar has a packing gland within the same about pipe 2 and adapted to be tightened by another collar 10 which is adj ustably bolted to the packing collar 8 and has a portion bearing against the packing under collar 8 to tighten the same. This provides for unequal expansion and contraction in said pipes or tubes, as unavoidabl occurs, and which has tobe taken care of 1n this way to avoid leakage of steam. As to this tendency .of the steam to leak it should be understood that the exceedingly'high temperatures employed are such that the said retort sections will become red hot. Hence the importance.

expand without disturbing the packing be- 1 tween them and without leakage, and the outer pipes 3 are facilitated in longitudinal expansion and contraction by rollers 12 on which they rest at their front ends and have free lon gitudinal .movement.

The furnace is shown as heated by means of oil by pipe 9 and superheated steam by pipe 11, and the steam employed in the retort for heating the oil therein flows from the boiler through pipe 15 and the coils 16 v Patented Feb. 5, let... Application filed February 5,1916. serialno. 76,376.

hat is, the elbow or joint (1 at the 'rear connegts the upper oil pipe sec the furnace and thence by a; 1,265,14id

therewith in the furnace and which are exposed to the superheating temperatures therein as also are the said retort sections. From these coils the superheated steam flows by the extension of said coil pipe through the side of the furnace wall to the union 17, which is purposely placed outside at this point to enable the coils 16 to be disconnected and removed when for any reason-this becomes necessary, and which removal is very liable to become necessary on. account of thehigh heat to which they are subjected. From the said'outside union or joint 17 the pipe returns within the furnace again by connection 19 to joints 20 at the front of pipe 21 to the several

steam distributing pipes

22, 23, 24 and 25 to the steam jackets of the said several retort sections a, b and 0: Each of the three down pipes from pipe 22 'to said sections is provided with a hand controlled valve 26, and pipe 22 has a blow-out 26 and a pressure gage 27 surmounts pipe 21.

Oil is supplied to the retort for vaporizing from a head or supply which emplovs a force pump,not shown, and the oil is driven under the requisite pressure through pipe 30 to a preheater or superheater 31 located -over the wall or top of the furnace and running the full length thereof from rear to front. The said superheater has an oil carrying pipe 32 on its inside and a pipe 33 about the same providing a jacket of superheated steam for said oil pipe. The pipe 33 is wrapped heavily with asbestos or the like to confine the heat, and oil flows into the rear end of the superheater by pipe 30, while superheated steam from the rear ends of vaporizing sections a b and c flows into the jacket 33 of the superheater by pipes 35 and'36.

From the superheater 31 the oil flows to the upper of the several retort sections by pipe 37 through an atomizing nozzle 40 at its front end and superheated steam from the superheater likewise enters the atomizer with the oil by pipe 38 and in such manner as to contribute most effectively to the vaporization and dissemination of the oil vapors with the steam. In fact, however, the oil is not only vaporized in the superheater but the vapors thereof are heated to a very high temperature so that when the oil vapors reach the atomizer 40 and enter the retort with the superheated steam they are in a state to commingle thoroughly therewith,

, and the said vapors and steam traverse the said retort sections together and issue in a superheated state from section 0 at the exhaust, 5 to the condensers or separators next in order.

By building the retort-in sections as shown of ma follow as shall be deemed desirable,

and o viously, there will be ultimate condensation and separation but the means for this purpose do not constitute a part of this invention.

What I claim is:.

1. The apparatus described comprising a furnace chamber, a plurality of retort sections in said furnace consisting each of an inner tube for oil and an outer tube for a steam jacket, the said outer tubes terminatin' with the furnacewalls and the inner tu es extending beyond the wall thereof, packing for said outer tubes on said inner tubes and joints connecting the ends of the inner tubes outside the furnace wall.

2. An apparatus as described, comprising a furnace, a plurality of retort sections exposed in said furnace on different horizontal planes and having inner oil tubes and outer superheating jackets terminating within the ends of the inner tubes, removable tubular joints connecting the ends of said inner tubes outside the wall of the furnace and an atomizer in the end of the upper of said sections to inject oil and steam together therein.

' 3. An apparatus as described, comprising a furnace and a sectional retort therein consisting of oil pipes extending through the walls thereof and steam jackets terminating at said walls having annular flanges at their ends and collars next to said flan es on said. oil pipes provided with packlng glands, and elbow joints connecting the ends of said oil pipes outside said glands, whereby expansion of said pipes can occur without causing leakage of the steam from said jackets.

4. In an apparatus as described, a plurality of retort sections openly connected at their ends and having steam heating jackets between their ends, in combination with an oil heater having a steam jacket openly connected by separate pipes with the jackets of said retort sections respectively.

5. In an apparatus as described, a plurality of retort sections at different elevations and provided with oil carrying tubes open one to the other at their ends and provided with steam jackets betweentheir ends, in combination with a tubular oil heater having a steam jacket about the same and pipes from the jackets of said retort sections discharging into the jacket of said oil heater, and pipe connections from said rero teoil heater and the jacket thereon arranged to discharge together into the upper of said retort sections.

6. In an apparatus as described, a, retort consisting of inner and outer tubes spaced apart to form a jacket between them and means providing for unequal expansion of said tubes comprising a packing for the ends of the outer tube about said inner tube and in which said inner tube is slidnbie, and W rollers supporting the corresponding end of the outer of said tubes behind said packing.
