l PARASCO ALIDJIADIS, YOFk NEW YORK, N.

OVEN.

To all whom it may concern:

a citizen of Turkey, and residing at New York city, county and State of New York, have invented a new and useful Improvement in Coke'Ovens, of which the following is a specification.

in which the highest quality coke maybe produced. c Y 1 Another object of this invention is toprovide a coke oven which can be built with a small amount of expense, which will use the heat of its fuel ywith the highest degree of efficiency and finally which cai'i'produ'ceyk the highest quality of, coke from inexpensive raw materials, like small coal, coal-dust and the like. Y

With the above mentioned and other ob# jects in view, my invention mainlyresides in building the coke oven` in three superimposed stages, the lowestl stage of it being an inexpensive rcommon furnace to burn stage whereinY the'heat of thegases of said furnace is used to produce a lowerv quality preliminary product and finally, the third stage which is the coke oven proper, being charged with coal-dust or, small coal in a wet condition and having heating flues in its walls adapted to transmit the remaining use-- ful heatin the gases of the furnace to the charge of said oven. whereby said charge will be slowly coked at a relativelyy low temperature.

For a full description of the invention and the merits thereof` and also to acquire a knowledge ofthe details of lconstruction of mentioned hereinbefore, reference is to be had to the following description and accompanying drawings.

The furnace 3 may be built in any conveii-- icnt manner of brick lined with refractory materials having the bottom G, the side walls and the-arched top 8. It may hai-.ie gra-.tes

n to burn the fuel on-the cheapestkind of This invention relates to coke ovens and has for its ma1n'ob3e`ct to `provide an oven coals-or they may be Vsimply thrown on the bottom 6 and the ashes removed intermittently or after having finished a coking operation. VIt may have a comparatively low c yiront door 9 showing the openings 10 adapted to regulate the air entering the furnace. The hot gases resulting from the combustion kof the fuel 11 thrown into said furnace will leave through the opening 12 in the'baek `'wall of the furnace and will enter through the channel 13 and opening 111 into the intermediate oven-ll. Said oven is built somewhat similar to the furnace 3 with a bottom 15, side walls 16 and arch roof 17. fn the front wall 18 of the same is provided a charging opening 19 through which the material to be coked can be thrown into the inside space 2G. Said material may be any desired coal but l preferably employ a cheaper grade. of it or dust and `small coal. The hot combustion gases 111 entering the intermediate oven will pass over the charge to the front partof said oven and will further continue their travel through the opening'V 21 provided in the the action of the hot combustion gases, the charge in the intermediate oven will be coked and the gases driven ofi from the same, will also leave through the opening 21 or aportion of them may be burned for 'further heat production, said burning depending'on the amount of the air introduced into the furnace 3 through the openings 10. The final mixture of combustion and distillation gases from the intermediate oven 4L will pass through the opening 21 and continue their travel in the checkered liues 22 and 23, pros vided in the bottom and in the side walls of the coke oven proper, constituting the third part of my device. The gases passing through the bottom and the walls finally unite in the iiues 24 and leave through the stack 25 into kthe atmosphere or they may be caught, washed and the valuable contents, tar and gases separated.

The upper furnace 5 alsohas an arched roof 26 provided with two or more charging and stamping'openings 27, and a front wall Vfront part of the roof of said oven. rilirougli Y LAagain.

with a door opening 29. The inside space 30 of said upper oven 5 will be filled by the material to be coked which may be the dust or small particles of some suitable coal and which I preferably prepare by wetting it lirst, charging it through the upper opening 27 and door 25) into the oven and stamping it thereafter. Under the action of the gases in the checkered tlues 22 and 23 the stamped mass of the small wet coal will undergo a slow cohing process and the colte produced from such inexpensive materials asy nien` tioned, will show the highest' possible. qualities as to hardness, size, heating value and so on.

It has been my experience with such ovens that they1 will produce ordinary good coke from the materials charged in the intermedifurnace in a period of about Vtwelve hours, while the full ccking of the charge in the upper oven will require about forty hours, so that the intermediate oven can be chai d and emptied three times, while one full operation is nished` in the upper oven. Whilethe operations are going on, the two doors i9 and /lwwill be well closed by heat insulating` materials, like bricks and the ready products may be removed through them after said openings have been freed In larger operations, mechanical means for removing the products and for charging the ovens may be` easily installed. The gases of the upper oven inay be left free to escape through the partly closed chargvling openings 27 or a separate pipe line, as

at 3l, may be installed soy as to catch said gases, separate their tar and oils and use these for combustion purposes thereafter. It also has been my experience with such ovens that the coke produced in the upper oven is of the highest possible quality and is especially adapted for metallurgical pur poses. i

Having thus described my invention what I claim as new and want toy protect by Letters Tfatent is:

1. In a coke oven, three structures; the first being a furnace adapted to burn fuel therein; the second a retort adapted to receive a charge of coal and having an elongated shape, a charging door, a connection to said furnace and an exit opening whereby the combustion gases of said furnace are forced to pass through said retort and to be in contact with the material therein; a third structure, being the colnng retort proper,

having an elongated shape, and heating its combustion gases in the rear wall of it;

a. second structure built above said furnace lia-ving an elongated shape and being adapted to receive a charge of coal partly filling the same, an opening in the rear wall of said intermediate structure connected to the exit opening of said furnace and an eXit opening in the roof of said second structure in the -front part of the salme, said second structure having appropriate charging and removing openings; a third structure, being the colte oven proper, built above the second structure and materially of the same dimensions andv shape as the two structures underneath the same, said coke oven proper comprising a retort with charging and removing openings for the coal, eolie and gases and with heating flues in its floor and side walls, the front end of said heating'flues being connected with the exit openings of said second structure and the rear end of said llues terminating in a stack.

3. In a coke oven, three structures; the iist being a furnace adapted to burn fuel therein; the second a retort to receive a charge of coal and to be heated by said furnace and by the combustion products of the saine, means for allowing gaseous con'ibustion products to pass from said furnace through .said retort in Contact with the material therein; and the third structure being the cking retort proper adapted'to receive a charge of coal and to be heated by the combined gaseous products of the first two structures and to slowly coke the charge in the said third structure thereby.

In testimony whereof, I have signed my name to this specification, this 21st day of February 1923.
