NILS KARL HERMAN EKELUNDJ OF JNKPING, SWEDEN.

COKlNG-FURNACE.

SPECIFICATION forming part of Letters Patent No. 514,546, dated February 13, 1894.

Application filed January 19, 1892. Seria-l No. 418,620. (No model.)

To all whom it may concern.-

Be it known that I, NILS KARL HERMAN EKELUND, a subject of the King of Sweden and Norway, residing at Jnlrping, Sweden, have invented certain new and useful Improvements in Coking-Furnaces, of which I declare the following to be a full, clear, and exact description.

The present invention relates to improvements in furnaces of the character described in the specification of Letters Patent of the United States, No. 344,321, of March 18, 1890.

On the annexed drawings Figure 1 is a longitudinal section of the furnace on .fr m Fig. 2 and Fig. 2 a cross section ou 'y y Fig. 1. Fig. 3 is a longitudinal section of the furnace on s e Fig. 2.

In the main the furnace consists of three chief parts or sections A, B and C. The upper section is destined for the drying, the middle one for the coking and the lowerone for the cooling. The upper section consists of two compartments A A2, located one above the other and separated from each other by intermediate partitions or diaphragme N with doors ninclined from the sides and from the middle. The central portion of the partition contains an elevated rail truck V', on `which the peat is introduced on dumping or tipping wagons to be thrown into the compartment A. The middle section by means of a partition wall Vaud intermediate floors U is divided into four compartments, two upper ones B B and two lower ones B2 B2. The bottom section by means of the intermediate wall Vl is divided into two compartments C C. There being besides in the intermediate wall and in two opposite side walls arranged other compartments G2 C2 C2. In theintermediate doors U between compartments B and B2 there are perforated sliding doors T. The arches or vaults F I are hollow, so as to form passages and in the arches F are pipes G, which through the bottom of the passage F- connect with the compartments B and descend outside to the compartments C2 through these compartments to the condenser P and the fan Q and from .the fan to the compartments C. In the passages l fireplaces E E2 E2 are arranged, to which iiues or pipes (Fig. 1 and dotted lines Fig. 2-) pass from the compartments C. Other pipes o. lead from the compartments C2 to the fan S, from which further pipes h lead into the passages F. In the walls there are sliding doors, by the opening of which the peat can be poured from the upper section into the middle one or from the middle section into the cisterns L, which rest on rail wagons. The sliding doors l-I between the npper and the middle sections are hollow and consist of alower solid'part and an upper perforated part. The compartments between these two parte communicate with the vaults F by small passages m.

The use and working of the furnace are as as follows. As previously stated, the drying takes place in the upper section Vor properly speaking in the compartment A2 and the coking in the middle section. The gases disengaged in the coking process pass frornthe compartments B2 B2 through the doors T up into the compartments B B and together with the gases evolved in these compartments into the pipes G. Through the pipes G the gases are led to the condenser and to the fan Q, which latter forces the gases into the compartments C', where they are heated, and from which compartments the gases pass through the fines or pipes o into the fire places shown at E Fig. 2. The hot combustion gases pass through the flues or pipes p into the compartments B2 and B and cause the coking. As there is a high temperature in the compartments C C owing to the radiation of heat from the cisterne L, the air in the adjoining compartments O2 becomes heated. This heated air is led through the pipes a', the fan S and the .pipes b into the passages F, where it is still more heated partly by the'walls of the same and partly by the pipes G and finally passes through theflues fm into the compartment A2. The peat is thus dried in the compartment A2 and the watery vapor evolved thereby can escape by valves or ilues arranged for this purpose. When the peat is completely coked in the compartment B2 the doors K are opened in order that the coke may fall down into the cisterne L by means of which the same, after having been cooled, is removed from the furnace. The doors K having been shut, the doors-T are opened and the half-coked peat in the compartment B is let down into the compartments B2. The doors I having been IOO shut, the doors H are opened and the dried peat in the compartment A2 is let down into the compartments B. The doors H having been shut the doors fn, are opened and the raw peat in the compartment A is let down into the compartment A2, whereupon the doors n are shut and the compartment A is filled.

The formation or division of the middle section vertically into two or more compartments two such, viz B and B2, being shown on the drawings, has the advantage that the peat is divided in layers one above the other, and that the heat in the gases from a lower layer is utilized in the upper ones.

What I claim is- 1. A coking furnace comprising a drying chamber extending across the upper part and divided into two parts by a horizontal partition wall N, N,provided with doors a central partition wall V beneath the drying chamber having a conical apex, grated doors opening in each side of the conical apex and leading to coking chambers, substantially as described.

2. A coking furnace comprising a drying chamber partitions N N, having doors dividing the chamber into two sections, inclined partitions U U forming the bottom of the lower section grated doors therein, cokin g chambers beneath the drying chamber, each of said chambers being provided with centrally arranged grated valves suspended from inclined partitions U U, substantially as de scribed.

3. A coking furnace consisting of a drying chamber divided horizontally by a partition N N inclining from the sides and from thc middle and provided with doors, a coking chamber, grated sliding doors between the drying chamber and coking chamber, inclined partition walls dividing the coking chamber into two parts, a grated valve in the partition wall and a cooling chamber beneath the coking chamber with a valved Opening between, substantially as described.

4. A coking furnace consisting of the drying, coking and cooling sections, said coking section being divided into two sections a division wall V between the coking chambers, hollow arches F in the apex of said wall at the bottom of the drying chamber and at each side in line therewith with openings from said arches to the drying chamber and openings to the arches from the coking chambers, substantially as described.

5. A coking furnace consisting of the drying, coking and cooling sections, said coking opposite sides of the furnace walls with openings to the coking chambers and openings from the cooling chambers to said arches and grates in said arches, substantially as described.

6. A cohing furnace consisting of the drying, coking and cooling sections, said coking section being divided into two sections, a division wall V between the coking chambers, hollow arches F in the apex ot said wall, at the bottom of the drying chamber, and at each Side in line therewith, with openings from said arches to the drying chamber and openings to the arches from the coking chambers, and arches I at the base of the partition V and at opposite sides of the furnace walls, with openings to the coking chambers and openings from the cooling chambers to said arches, the walls of the cooling chambers being made hollow and pipe connections therein in connection with fans and condensers, and connecting also with the arches, substantially as described.

In Witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
