COKE 'OVEN Filed April 16, 1955 Patented `lune 20, 1939 iJNlTED STATES PATENT OFF-ICE COKE OVEN Application April 16, 1935, Serial No. 16,688 In Germany April 26, 1934 5 Claims.

It is known practice to arrange horizontal carbonising retorts, heated by radiation, in coke oven chambers, for treating pit coal. It is also known practice to increase the temperature drop between the heating flue and the chamber wall by fitting a refractory stone lining in the oven chamber. In contrast thereto, according to the present invention it is intended that low or medium temperature coking of pit coal shall be carried out in existing coke ovens at low heating temperatures, for example 700 C., while dispensing with means for increasing the temperature drop inside the masonry wall between the heating flue and the chamber.` In order, however, to produce a suiciently rapid transmission of heat between the chamber wall and the coal charge with such low heating ue temperatures, according to the invention, the chamber space is subdivided along its length into a plurality of transverse radiation spaces between which a fuel mass of lesser thickness than the actual breadth of the chamber is carbonised.

The arrangement according to the invention will be described with reference to a typical eX- ample of construction.

Fig. 1 of the accompanying drawing shows a vertical longitudinal section through a horizontal coking oven chamber taken along the line l-l of Fig. 2.

Fig. 2 shows a plan of the arrangement according to the invention along the horizontal section line II of Fig. 1.

The subdivision according to the invention of the coking oven chamber I into a plurality of radiation spaces in the form of construction as shown in Figs. l and 2, is brought about by the insertion through apertures 'I in the oven cover 3 of vertical iron members 5 of H-shaped crosssection disposed at short intervals along the length of the chambers. The inserted members or hollow formers 5 may, as desired, be inserted in the oven chamber either when the latter is empty or full. If the hollow members 5 are inserted in the oven chamber when it is already full, a considerable compression of the chamber charge takes place and this compression enhances the quality of the carbonising coke and increases the average output of the oven. With strongly active coal, however, this method of insertion will not be employed, but the coal will be inserted from above into the spaces after the members 5 have been inserted. With a chamber breadth of for example 450 mm., the area of these spaces measures about 200 X 450 mm. By means of the heat radiation inside the hollow members 5 and by means of theincreased transmission of heat by the iron walls of the hollow members 5, the coking or the carbonisation of the column of coal in the spaces 4, in spite of the fact that the temperature is kept low in the latter, is accelerated considerably as c-ompared with normal carbonisation in chamber ovens. There is in consequence produced a carbonising coke of homogeneous structure, i. e. a coke having substantially no structural differences in the interior thereof.

While it is preferred to insert the H-shaped cross-sectional members 5 through the oven cover, it is to be borne in mind that said members may be conveniently inserted from one or both ends of the oven chamber. v

There is in this application specifically described one form which the invention may assume in practice, nevertheless it will be understood that this form of the same is shown for purposes of illustration and that the invention may be modified and embodied in various other forms without departing from its spirit or the scope of the appended claims.

What I claim is:

1. In combination with a horizontal coke oven having uninterrupted chamber space, means for producing low or medium temperature coke (Sernicoke) in said chamber space and comp-rising individual partition members adapted to be inserted in the oven chamber and vertically and transversely disposed therein, said members extending entirely across the oven chamber and being spaced apart from one another to divide the chamber into a plurality of radiation spaces and a plurality of fuel spaces alternating therewith, and the coke oven being constructed to permit insertion of the partition members from above.

2. In combination with a horizontal coke oven having uninterrupted chamber space, means for producing low or medium temperature coke (semi-coke) in said chamber space and comprising individual partition members adapted to be inserted in the oven chamber and vertically and transversely disposed therein, said members extending entirely across the oven chamber and being displaced from one another to divide the chamber into a plurality of radiation spaces and a plurality of fuel spaces alternating therewith, the dimensions of each of said fuel spaces measured along the length of the chamber being less than the width of the chambenand the coke oven being constructed` to permit insertion of the partition members from above.

3. In combination with a horizontal coke oven other and providing between them a plurality of fuel spaces in said chamber, and each partition member serving of itself toprovide a radiation space between adjacent fuel spaces, and the coke -oven being constructed to permit insertion of the partition members from above.

4. In combination with a horizontal coke oven having uninterrupted chamber space, means for producing 10W or medium temperature coke (semi-coke) in said chamber space and com- 0 prising individual partition members adapted to be inserted in the oven chamber and vertically and transversely disposed therein, said members extending entirely across the oven chamber and being spaced apart from one another and dividing the chamber into a plurality of fuel spaces, and each partition member serving of itself to provide a radiation space between adjacent fuel spaces, and the coke oven being constructed to permit insertion of the partition members from above.

1 5. A coke oven comprising an elongated and uninterrupted chamber space, heating flues on either side thereof, and a plurality of spaced metal partition members of H-cross-section extending entirely across the chamber space and vertically arranged therein, the flat or long sides of each H-member being disposed transversely to the chamber space, and the coke oven being constructed to permit insertion of the partition members from above.
