SPECIFICATION forming part of Letters Patent No. 480,248, dated August 9, 1892.

Application 'filed May 6, 1888. Serial No. 272,954. (No model.)

To ctZZ whom it may concern.-

Be it known that we, JOSEPH I-I. COLLINS, Jr., of the city and county of Philadelphia, State of Pennsylvania, and ISAAC N. KNAPP, of Greenwich, county of Fail-field, State of Connecticut, have invented a new and useful Improved Apparatus for Manufacturing Gas, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part of this specification.

Our invention relates primarily to the construction of apparatus for manufacturing gas by the practically-continuous destructive distillation of pulverized carbonaceous matter, appliances bein g preferably used with such ap paratus whereby steam at high temperature is brought in contact with the hot carbon residue of the distillation, so as to form by its decomposition carbonic-oxide and hydrogen gas, and provision being also preferably made for the introduction of hydrocarbon oils and for maintaining the mixed gases and vapor at a high heat for a sufficient time to insure the formation of a fixed gas. o have also made certain improvements in producer-gas generators and in the system of burning the pro-,

ducer gas to heat gas-rctorts which are especially designed for use with the apparatus before referred to, and which will best be understood after a description of the apparatus shown in the drawings.

The apparatus herein described is designed and intended for the carrying out of certain improvements in the method or process of making gas which we have invented, and which forms the subject-matter of Letters Patent No. 463,139,dated November 17, 1891, the leading features of said process consisting of the continuous production of gas by feeding finely-divided coal-dust or other carbonaceous matter into a narrow vertical and externally-heated retort, so as to effect a destructive distillation of the dust and a high heating of the carbonaceous residue, introducing steam into contact with said heated carbonaceous matter, so as to form water-gas, and, if desired, enriching the gases by the introduction of oil, all of said steps being carried on in externally-heated retorts, so that the production of gas is continuous and uniform for any length of time.

Our present application is intended to cover the mechanical features of what We believe to be the best construction of apparatus for carrying out our said process in its most perfect development, many of said features being, however, capable of useful application independent of each other.

Reference being now had to the drawings which illustrate our invention, Figure 1 is a plan view of a gas-making apparatus having our improvements; Fig. 2, a similar view in section on the horizontal plane indicated by the line 6 6 of Fig. Fig. 3 is a vertical section on the broken line 7 '7 of Fig. 2. Fig. 4

is a vertical section on line 2 2 of Fig. 2. Fig. 5 is a vertical section on line 1 l of Fig. 2. Fig. 6 is a vertical section on line l 4 of Fig. 2. Fig. 7 is a vertical section on line 5 5 of Fig. 2. Fig. 8 is a similar section on line 3 3 of Fig. 2; and Fig. 0 is a horizontal sectional view of the four-way valve marked H in the drawings.

A indicates a producer-gas generator, as shown in the drawings, and as we prefer to construct it we provide it with two air-admission openings or passages A and A one above and one below the grate, (indicated at a in the drawings,) and each opening being adapted to be closed at will. We also provide it with two gas-exit openings or passages A and A, which, like the air-openings, are situatcd one below and the other above the grate a.

a and a are valves, by which gas-openings A and A can be closed or opened at will, and A is a conduit or flue leading from passage A into the same conduit or line, (marked C in the drawings,) which leads from opening A and through intermediate flues, &c., hereinafter described, connects it with an exhauster, (marked F in the drawings.) In

normal operation the air-opening A and gasopening A are closed and the openings A and A open. The exhauster then creates a suction in flue C and the air enters the generator through opening A, passes through the fuel on grate a, and the producer gas formed enters the flue O through openings A \Vhen it is necessary to clean the fire at the grate a, openings A and A are closed and openings A and A opened, the suction in flue C then drawing air into the generator through opening A and upward through the fire, the gas passing out through opening A and flue A to the flue 0. As will be seen, the generation of gas need never be interrupted where this device is used, a fact of prime importance where, as in our apparatus, an uninterrupted process is to be carried on.

B indicates the main structure of our apparatus. It contains the retorts and heatingfiues, and is preferably built of brick inclosed in an iron shell. The fines A and C, already referred to, are formed in this structure, the flue 0 leading from the generator A to a fluechamber 0 in the front wall of structure B. (See Figs. 3 and 7.) C and C are upright fiues or branches leading out of chamber 0 and having valves C and C by which they can be closed or their opening regulated.

D, D, D and D indicate upright fiuechambers lying inside the fiues O and C and connected with them by means of the fluepassages d d, d d, cl 01 and d d the flues d leading from O to D; lines (1 from C to D; flues d from C to D and flues d from C to D and each of said flues having regulating-valves (indicated at c, 0, c and v The duplication of the said fluesis advisable, as enabling a better distribution of gas to be effected in the flue-chambers D, &c.

E, E, E E E and E are vertically-arranged rows of combustion-fines e e, &c., preferably made square in section and each row being placed at some little distance from the one adjoining it-say about three inches-so as to form narrow vertical spaces, as shown, and hereinafter referred to as retorts. The finerows E E, &c., are connected with the fluechambers D D, &c., and with similar fluechambers D D and D at the back of structure B, so as to form a continuous tortuous passage for the gases, as indicated by the arrows in Fig. 2, and we will hereinafter refer to the system of upright flue-chambers D D, &c., as connacting-chambers, a name which correctly describes their function.

F is an exhauster; G, a pipe-section connected with the exhauster; G, a pipe-section opening to the air; I and l, pipes leading from pipes G and G, and H a four-way valve, by moving which pipe I is connected with the pipe G and the exhauster and pipe I with the air through pipe-section G, or the reverse connection made at will. Pipes land I load, respectively, into regenerators-such, for instance, as are indicated at J and J the regenerator J being connected by flue K with connecting-chamber D and the regenerator J by fiue K with connecting-chamberD valves k and is being provided, so that the opening of fines K and K can be regulated at will.

The operation of the above-described heating system of our apparatus is as follows: The valve H is turned, for instance, so as to connect the pipe I with the exhauster F and the pi peI with the open pipe G. The exhauster is then set in operation, with the result of drawing in two currents of air, the first entering the generator A and passing through the fuel therein into flue C as producer gas, which is led to flue-chamber G and, the valve 0 being opened, to flue 0 from which itis admitted to chamber D through fiues (l. The second current of air is drawn in through pipe-section Gand passes through pipe I,

, regenerator J, and conduit K into the chamber D, where it meets the producer gas and supplies oxygen for its combustion. The burning gases are drawn by the exhaust from chamber D through the fiues eof the vertical row of fines E, thence through chamber D and flue-row E to chamber D, and so on through to the combustion-fines and connecting-chamber, as indicated by the arrows, until from chamber D the gases pass through conduit K to the regenerator J, which they raise to a high temperature, and after leaving which they pass through pipe-section G to the exhauster and thence escape. The c0mbustion in the fines E E, &c., is regulated by means of the valves shown and before referred to, prod ucer gas beingintroduced in any or all of the connecting-chambers D, D, D and B, if desired. Atintervals the cock H is turned, with the result of reversing the course of the burning gas and air through the fluesE E, 850., and the additional result of causing'the air which supports combustion to pass through the regenerator heated up by the products of combustion, while the second regeneratorthen again begins to store heat.

As we have already pointed out, the vertical rows E-E, &c., of combustion-fines are erected at a short distance from each other, so that a narrow vertical space or chamber is formed between adjoining rows. These chambers are the retorts in which we carry on our process of making gas; and the relative arrangement of retorts shown and which we are about to describe is that preferred by us, but not, as will be recognized, essential; and we would here note that the generator, flue, and regenerator system shown and above described is given by us as in our belief the best for use in heating our retorts and not as essential to the use of said retorts, which might be heated by any convenient system.

L is a vertical, narrow, and externally-heated retort-chamber opening at the bottom into an enlarged chamber N through an elbow L.

. L is a steam-pipe entering the top of retort-chamber L.

L is a valve. Z Z, &c., are battle-tiles secured this retort in our apparatus is as a superheater for steam. M is a similar vertical, narrow,

and externally-heated retort, at the top of the hopper M with finely-divided coal-dust or other finely-divided carbonaceous material, and by means of feeder M feed such dust evenly and continuously into the retort M, through which it falls into'chamber N. A pipe L, with valve L is shown in Fig. 5 to indicate that steam may, if desired, be introduced into retort M as well as coal-dust.

O is a retort-chamber leading out of chamber N; P, a similar retort connected at top with O by passage 0.

O is an oil-injector pipe having a valve 0 0 and p are openings through which retorts O and P can be cleaned.

Q is a chamber into which retort P opens at bottom; R, a retort-chamber leading from chamber Q to a conduit S.

S are pipes connecting conduit S with the hydraulic main T in the usual way.

N and Q, are ash-pans.

B, B B and B are Walls which separate the retort-chambers into virtually three independent sets of retort-chambers, the steam-' pipes, dust-hoppers, oil-pipes, and exit-conduits being also similarly divided, as is shown, so as to make each division independent of the others. Of course any convenient number 0t such divisions can be made.

To explain now the operation of our process in the above-described apparatus, the retorts are of course first heated to the necessary temperature and this heat maintained by external combustion, the heatin g system shown being such as by manipulation of the valves or a reversal of the direction of combustion to enable the engineer to control the temperature of the retorts at will. The finely-divided coal-dust is then fed into the vertical retort M and, falling between the walls thereof, a destructive distillation is effected and coal-gas, togetherwith finely-divided and very hot coke, will issue from the bottom of retort M into chamber N. Steam is introduced into chamber N, preferably through the retort L, already described, so as to heat it very hot, and coming in contact with the hot particles of coke it combines with it, forming watergas orcarbonic oxide and hydrogen and ash, which last falls into the pan N and can be removed at will through the openings U. As before noted, steam can at pleasure be admitted into the distillation-retort M, in which case water-gas, as well ascoalgas, will be formed in said retort. The chamber N is made of comparatively-large area compared with the retorts, so that the ash may the more readily settle out of the gases which pass from it through retorts O P, chamber Q, and retort R to the hydraulic main. NVhere it is desired to enrich the gases, hydrocarbon oil canbe introduced, as by pipe 0 The vaporized oil, passing through the retorts (P and R, as shown) in admixture with the gases, forms a'fixed and rich compound gas therewith. The coaldust can be fed into any number of successive retorts and steam and oil introduced at more than one, the number and arrangement of the connected retorts being, of course, variable at the discretion of the constructor. As ash is to a greater or less extent carried through all the retorts, itwill be well to form chambers-such as N and Qat the bottom of each'two retorts and to provide ash-pans in each of said chambers.

Having now described our invention, what we claim, and desire to secure by Letters Patent, is p 1. In a gas-producing apparatus, two sets of vertically-disposed combustion-fines, said sets being spaced at a distance apart substantially equal to the thickness of one of the flue-walls and forming a narrow vertical retort, a feeding device for supplying pulverized carbonaceous material in regulated quantity to the top of the narrow vertical retort thus formed, a receptacle for solid matter'at the bottom of said narrow vertical retort, and a conduit for gas leading from near the bottom of the retort, substantially as described.
