AUGUST PUTSCH, or scorn BETHLEHEM, PENNSYLVANIA, ASSIGNOR or ONE-HALF TO F. 0. DETTMANN', OF NEW YORK, N. Y.

VERTICAL COKE-OVEN.

Application filed June 4, 1915 To all whom it may concern:

Be it known that I, AUGUST PU'rsoH, a citizen of the German Empire, and resident of South Bethlehem, county of Northampton, and State of Pennsylvania, have invented certain new and useful Improvements in Vertical Coke-Ovens, of which the following is a specification.

According to the usual practice coke ovens are built horizontally, and being thus spread over considerable area are subject to certain defects as to economy of operation. The

object of my invention is to reduce the floor area required and at the same time so construct the vertical oven as to increase the efficiency and economy in operation. A further object is to facilitate the removal of the coke by having the oven space trapezoidal, or wider and longer at the bottom than at the top so that the mass of coke will readily drop out. A further object is obtained by providing as the floor of the furnace a trap door adapted to be water sealed to prevent gas leakage. The door is hinged at one end and adapted to drop down when the coke is to be discharged the door thus serving as a chute for directing the discharged coke to the coke wharf where it is handled in the usual manner. Sealing the door with water or sand according to my arrangement makes the door practically self sealing and obviates the use of luting clay which is troublesome and does not always remain effective. In my improved construction I employ vertically arranged regenerators and horizontally arranged air and heating flues. banked one above the other, the latter being connected with the regenerators in such manner that the direction of flow of the air and products of combustion may be reversed at desired intervals. A further improvement relates to the gas admission and air control at the point of combustion.

In the accompanying drawings I have illustrated my improved coke oven embodying the several features of my invention. Figure 1 represents a longitudinal vertical section through one of the ovens; Fig. 2 represents vertical transverse sections along the lines AA and BB of Fig. 1; Fig. 3 represents a broken vertical longitudinal section along the line 33 of Fig. 2; Fig. L is a horizontal section at H of Fig. 2; Fig. 5 is a similar section taken at 5 5 of Fig. 2; and Figs. 6 and 7 represent Specification of Letters Patent.

graphically the flow of air and products of combustion when operating direct and reverse.

Referring to the drawings 1 represen one of a series of coke ovens arranged vertically. The upper end of the oven at 2 is of less cross sectional area than the lower end at 3 so that a vertical cross section in either direction is a trapezoid. This wedge shape to the oven space facilitates the dis charge of the coke when the bottom door is opened. The upper wall of the oven is provided at 4: with an opening for charging the same and a gas exit is provided at 5. The series of ovens is built upon a suitable supporting frame consisting of I-beams or the like 6. The ovens are thus elevated above a chute 7 which is adapted to direct the finished coke to the wharf 8 where it may be removed in. the usual manner. The entire bottom of the oven preferably comprises a downwardly opening trap-door 9 lined with fire brick or the like 10. The door 9 is preferably provided with an apron 11 turned up all around the edges to form a trough substantially as indicated in Figs. 1 and 2. The lower opening of the door casing of each oven is provided with a depending flange 12 adapted to lie centrally of the trough or groove 11 of the door and thereby form a seal which may be completed by filling the trough 11 with water or sand. If water is used suitable supply pipes (not shown) may be provided for filling the seal troughs 11 of the several doors. The doors 9 are preferably of cast iron and each provided with a pair of forwardly extending cars 13 whereby the doors are pivoted at 14 so that when each door is dropped it will lie upon and cooperate with the chute 7. The other end of each of the doors is preferably provided with a pair of projecting arms or lugs 15 to which suitable cables or ropes 16 are attached for lifting and closing the respective doors. It is desirable that, when closed, the doors 9 be held firmly in place so that the seal in the channel or trough 11 will not become broken. For this purpose any suitable wedging or clamping means may be employed such as the wedge 17 driven between the door and a bar or rod 18 suitably supported from the I-beams 6, substantially as shown in Figs. 1 and 2 of the drawings.

The Wedge 17 is preferably made of spring bustion.

steel in open formation so that the spring of the wedge will hold it in place.

The several ovens of the series are arranged side by side and separated by cellular partitions provided with a plurality of horizontal tubular conduits or fines for the circulation of air and the products of com- The ends of the fines of each cell are connected with fines connected with regenerators of the checker brick type which in the present case are arranged vertically.

The regenerators are located in front of the ovens 1, and each is provided with a dampered air inlet pipe 21. Flues 22 are connected with the tops of the regenerators,

and each may alternately serve to conduct hot air or the hot products of combustion, as will be'more fully explained hereinafter. Each regenerator 2O is'also adapted to commnnicate with a conduit 23 connected with the smoke stack or chimney for carrying off the products of combustion.

The fines 22 are each provided with branch pipes 24 alternating 011 each side thereof, sow and pig fashion, the branch pipes of adjacent fines 22 interlacing or alternating as indicated in Fig. 2 of the drawings. Each branch fine 24 communicates with a horizontal fine '25 in the dividing wall between adjacent ovens 1. The fine 25 is central horizontally of two other fines 26 with which it communicates by a transverse opening 27, see Figs. 4 and 5. The parallel side fines 26 communicate at their forward ends with the corresponding fines 26 above or below in the same cell (see Fig. 3) these in turn communicating with another central fine .25 which in turn connects with oneiof the branch pipes 24 of the adjacent fine 22. Each series of commnnicating fines .2526 are separated from the adjoining series by a solid partition 28 whereby each cell becomes a separate heating unit in which the circulation of air and the products of combustion may take place in either direction according to which regenerator is being heated. It will thus be seen that in each cell the fine connection is continuous from the air inlet pipe 21 through one generator 20, fine 22 branch '24 and returns through the branch 24 and fine 22connected with the adjacent regenerator ,20 and thence to the chimney through the fine 23, the first regenerator bein adapted to heattheincoming air and the ot ierbeing of combustion. After a predetermined period of operation in this manner the direction of circulation is reversed and the first .regenerator is reheated by the products of combustion.

The gas for heating the .oven is preferably introduced ,at the cross .Or branch fines 27 by two pipes 29 branching from a main 30, and by two pipes 31 from a main 32, the two pipes or burners 29 and the two similar pipes or burners 31 being directed into the two fines 26 above and below the dividing 'wall 83 respectively. It will be seen that the gas may be admitted to one or the other sets of burners 29-, .or 31, according to the direction of flow of the air and products of combustion. The gas bnrners or pipes 29 and 31 are preferably centrally arranged in the ends of the fines 26 substantially as shown in Fig. 3 and removable air nozzles 34 are inserted above and below the burners. The wall back of the burners is also preferably provided with holes'opposite the air nozzles 34 which are adapted to be closed by bricks 35. The nozzles 34 are preferably seated in tapered holes and nozzles of various sizes are provided to interchangeably fit the tapered holes so that the amount of air admitted may be varied. By removing the bricks 35 the nozzles may be changed when desired or the operation of the burner inspected.

In order to more clearly understand the operation, the circulation of the air and the products of combustion are indicated by arrows on some of the sectional drawings but to more clearly illustrate it, both direct and reverse, .two diagrammatic views aregiven in Figs. 6 and 7 and letters are used to designate the different fines and associatedbeing ignited, the products of combustion return in the fines Z) (26) along the walls of the oven and at the forward end turn up and traverse the fines 7) (26 above the septum 33) turn at f in a horizontal plane and enter the central flue e thence through a? (branch 24 and fine 22) to the regenerator B (20), through which it passes and then by tunnel g (23) enters the chimney. Fig. 7 indicates the currents when the apparatus is reversed and the air enters through B, d, e, and .meets the gas at f, the products of combustion traversing fines Z) to 6 turns at f into 6 thence through d, B and g to the chimney. During the reverse operation the gas is supplied from the main a (32) through the upper pair of burners When the coking processis completed the wedges 17 and bar 18 are removed and the doors 9 -10 lowered, thus allowing the coke to drop out and slide down the door and chute to the wharf or platform 8, the trapezoidal shape of the oven facilitating the exit of the coke therefrom.

It will be understood that various modifications in the specific details of construction may be made without departing from the spirit and scope of my'invention as de- 7 fined in the appended claims.
