UNITED STATES TENT WILLIAM E. ROBERTS, OF NEW YORK, N. Y., ASSIGNOR, BY MESNE ASSIGNMENTS, TO FOUNDATION OVEN CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.
COKE OVEN.
Application fi 1ed,Augu st 8, 1919. Serial No. 316,009.
Tov all whom it concern:
Be it known that 1, WILLIAM E. ROBERTS,
a citizen of the United States, residing in,
the city, county, and State of New York, have invented certain new and useful Improvements in Coke Ovens, of which the fol-- lowing is a specification.
My invention aims to provide an oven which shall be evenly heated, economical and simple to construct and relatively easy to operate and keep in repair.
The oven is designed to operate without reversing the direction of the air and gases,
and therefore requires no special reversing valves and operating mechanism such as is necessary with typical ovens of prior constructions.
In the accompanying drawings in which corresponding characters refer to corresponding parts in the several views- Fig. 1 is a longitudinal section through the oven showing one tier of combustion and waste gas flues, and the waste gas and air ducts;
Fig. 2 is a transverse section on the line 2--2 of Fig. 1;
Fig. 3 is a detail horizontal section on the line 3-3 of Fig. 1; v
Fig. 4 is a similar horizontal section through the flues on the line H of Fig. 1;
Fig. 5 is a longitudinal section through an oven of modified construction and Fig. 6 is a transverse section on the line 6-6 of Fig. 5.
eferring now to the embodiment of the invention illustrated in Figs. 1 to 4, the oven is supported on a mat or foundation 10 in which is formed a tunnel 11 for carrying oil the burnt gases. This tunnel forms an outlet for all the waste gases emanating from the multiplicity of fiues formed in the oven and to be hereinafter more fully described.
The oven consists of a structure of masonry having a plurality of parallel tiers of flues formed therein, each tier comprising a plurality of combustion and waste gas fiues which fiues are connected together at the top and at their bottom ends communicating respectively with as and air ducts and a waste 'gas duct. okin chambers are formed in the structure etween the several tiers of flues. The several tiers of fiues are identical in construction and, therefore, a detailed description of one tier will sufiioe for all. However, it is to be noted that the combustion chambers in one tier of flues are opposite the waste gas chambers in the adjacent tier so as to assist in the equal distribution of theheat within the oven. The several tiers of flues are connected with individual gas, air and waste gas ducts in a manner to be presently described.
Immediately above the foundation waste gas ducts 12, 13 and 14 are formed in the body 15 of the oven. The ducts 12 and 13 are connected to each other by a port 16 in the center of their length, the ducts 13 and 14 are connected at their opposite ends by ports 17 and 18 and the duct 14 is connected with the tunnel 11 by a port 19. Each tier of flues comprises a plurality of upright combustion flues 20 and waste gas fiues 21 separated from one another by a wall 22. Gas is supplied to the severa combustion chambers 20 through a gas duct 23 running longitudinally beneath each tier of fiues and connected with the combustion flues by short branches 24. Nozzles 25 each having a restricted passage formed therein are placed in the branches when a gas of high thermal value is utilized. These nozzles can be removed so as to provide an orifice of more generous dimensions when a gas of low thermal value is to be utilized.
The flues in the several tiers are indentical as above described as to gas, air and waste gas connections but are-arranged as shown in Fig. 4 so that. the combustion flues 20 in one tier are located opposite to the waste gas flues in the adjacent tier. This arrangement assists in the equal distribution of the heat through the walls of the oven.
In Figs. 5 and 6 I have shown an alternative construction in which I provide two combustion chambers 20 and 20 which communicate at their upper ends with a chamber 30 which chamber in turn communicates with waste gas flue 21 The gas for combustion is sup-plied to the flues 20* and 20 from a gas duct 23 having branches 24 leading to said combustion flues. The burnt gas flues 21 are connected by branches 31 to a waste gas duct 14 which in turn is connected by branches 14 and 14 with the tunnels 11 and 11*. tion is supplied through a circuitous duct 32 having branches26 communicating with the several combustion chambers. Sliding bricks 28 are provided to regulate the flow of gas through the ports 27 so as to provide means for equalizing the temperature in different parts of the oven. This oven "operates on the same general principles as the one previously described the gas and air flowing The gases com exhausting on both sides of the waste Air to supportcombus upwardly in the direction of the arrows through the flues 20 and 20 the waste gases flowing downwardly and out by way of ports 21 to the waste gas flue 14 and thence by each of the branches '14 and 14 to the nearest tunnel 11 01'' 11 The coke ovens herein described aredistinguished from the typical forms of ovens now in use in that the gases flow continuously in one direction. This eliminates the multiplicity of valves necessary in the typical forms of ovens and also eliminates the apparatus for simultaneously operating the several valves of the oven.
Though I have described with great particularity the construction of the specific embodiment illustrated it is not to be construed therefrom that I am limited thereto as changes may be made by those skilled in the art without departingfrom the invention as defined in the appended claims.
What I claimis:
1. A coke oven having a plurality of rows of combustion and waste gas flues which are l connected at their upper.- ends, individual waste gas ducts adapted to carry oil the waste gases from each row of. combustion flues, said waste gas ducts each comprising a plurality of passages located in the same vertical plane above one another, the lowest passage communicating with an outlet tunnel air supplied to each row of combustion flues must flow successively through the passage gas ducts so that it is thoroughly preheated.
2. A coke oven arranged to continuously circulate the air and waste gases in the same direction without reversal and without preheating the air in regenerators, including in combinationfcombustion and waste gas flues which are connected at their upper ends, waste gas ducts located below'said flues, each of said waste gas ducts comprising upper, lower and intermediate passages'12,13, and 14 respectively, the upper and intermediate passages 12 and 13 being connected by a port 16 near the center of their length and the lower and intermediate passages 14 and 13 being, connected by ports 17 and 18 at their ends and the lower passage having a discharge outlet 19 near the center of its length and saidupper passage 12 being connected by branches 31 with said waste gas flues, and
out passing it through regenerators and branches 31 connecting said air ducts with said combustion flues.
In witness whereof, I have hereunto signe my name.
WILLIAM E. ROBERTS.
