Definitions
- the invention relates to a method for coking coal with high propellant pressure properties in a "non-recovery" or "heat-recovery” coke oven, wherein a coke oven bank, which is constructed of juxtaposed coke oven chambers, is used for the cyclic coking of coal, and wherein a pre-heated to a certain temperature amount of coal is admitted in such a filling height in the coking chamber to be filled, that the resulting by coking motive pressure in the gas space above the coke cake can escape, so that the Koksofensch framing coke oven chamber walls of the in the Coking resulting pressure to be relieved.
- the invention also relates to a device with which this method can be carried out.
- Coke oven chamber walls are often equipped with a complex transverse anchoring system consisting of anchor stands, wall protection plates, chamber frames, prestressing springs and anchors.
- An example of a transverse anchoring system of coke oven chamber walls is taught by WO 2009141086 A1.
- Driving pressures arise in the coking of coal in the so-called plastic zone of the coke cake by the elimination of volatile coal constituents and tar and by Teernaht Struktur, which results from the coincidence of plastic zones.
- the cause of the motive pressure is the so-called internal gas pressure, which arises in connection with the dilatation and contraction of the coal.
- the internal gas pressure acts through the already coked coal on the coke oven chamber walls, since the coke first forms near the wall through the hot coke oven chamber walls.
- Coking coal can produce high propellant pressures that damage the coke oven chamber walls.
- the maximum driving pressure occurs after approximately 75% of the operating time, which is defined as the period between two filling operations. Since the biasing springs of the transverse anchoring system serve to capture the driving pressures, they must be strongly biased and often adjusted accurately to avoid damage to the coke oven chamber walls by the driving pressures.
- the Koksofenschmitter must be repaired not least by the action of the driving pressures often when the Querverank fürssystem improperly set or in the course of Lifetime of a furnace was not maintained. Since the amount of propellant depends mainly on the type of coal used or the mixture of types of coal, one is often severely limited in the choice of coking coal species. It is therefore not possible to choose for the first time such coals for coking which are particularly suitable for the intended use. It is also possible to reduce the formation of the driving pressures by adding an additive to the coal to be coked. These are, for example, coke breeze, coals with a high volatiles content and inert matte coal. However, an addition of additives is not always desirable since an undesirable influence on use processes is possible here as well. Finally, the coking rate also depends on the water content, the content of volatile carbon constituents, the layer height and the bulk density.
- the filled coal must always be leveled by a mechanical leveler after filling through the filling holes in the furnace roof to convert the bulk cone into a furnace lining with a homogeneous height. This makes the coking process uniform.
- the leveling bar is guided through lateral leveling holes in the oven door into the oven. The construction is expensive.
- the invention solves this problem by a method for coking coal with high propellant properties in a "non-recovery” or “heat recovery” - coke oven bank, said
- a coke oven bank constructed of juxtaposed coke oven chambers is used for the cyclical coking of coal

- the coal At the elevated temperature of 100 ° C to 400 ° C, the coal reaches a quasi-liquid state, which is characterized by fluid-like flow properties, so that a particularly efficient and uniform filling of Koksofenbänke is possible. As a result, the control of the coking process is simpler and the quality of the coke is significantly improved.
- DE 4204578 C2 describes processes for pre-drying and preheating feed coal by heat recovery from hot raw gas, which is characterized in that wet feed coal is brought into contact directly with hot raw gas in countercurrent, the case of an operating temperature of 700 to 900 ° C. is returned to an outlet temperature of about 550 ° C.

- the coal is first pre-dried and then preheated. As a result, pre-drying and preheating can be set within wide limits.
- DE 2706026 A1 describes a method for conveying preheated feed coal in coking chambers and an arrangement for carrying out the method, wherein the feed coal from one or more dosing storage tanks pneumatically by means of a pressurized neutral support medium, for example nitrogen, above the center is supplied to the coking chambers, where the carrier medium is separated from the feed coal in a degassing manifold and then distributed by gravity into one or more pipe chutes and directed into the coking chambers.
- the temperature of the preheated coal starting from the prior art, be 100 to 280 ° C.
- the coal reaches a quasi-liquid state, depending on the type of coal, so that a uniform loading is possible. Also, the water content, the content of volatile coal constituents, the bulk density, the layer height, the type of coal, the membership of certain Mace- ral weakness and the coking rate by the preheating and the uniform feed no longer play a role.
