Claims
- 1. A device for the production of molded metallurgical coke from dried coal or fine coal mixtures with a low swelling index, comprising:
- means for forming briquettes;
- a vertically extending reactor with a common jacket having an oxidation chamber adjacent the top thereof for receiving the briquettes, an indirectly heated vertical coking chamber directly below the oxidation chamber and a cooling chamber disposed directly below the coking chamber for directly cooling the briquettes using a cooling gas ;
- means for circulating heating gases around said coking chamber and then upwardly across said coking chamber for indirect heating thereof, and into said oxidation chamber;
- a top double air lock chamber connected to a top of said oxidation chamber for admitting the briquettes; and
- a bottom double air lock chamber connected to a bottom of said cooling chamber for discharging briquettes;
- said means for circulating heating gases operating to supply the heating gases from around said coking chamber to said oxidation chamber with an oxygen content of about 2% to 6% to surface oxidize the briquettes directly;
- said coking chamber having an outlet for crude coke gas.
- 2. A device according to claim 1 wherein said coking chamber has a gas outlet at a level corresponding to 3/4 of the height of said coking chamber.
- 3. A device according to claim 2 including crude gas purification means connected between said coking chamber outlet and an inlet to said means for circulating heating gases, for supplying purified crude coke gas to indirectly heat said coking chamber, said means for circulating heating gases including an additional inlet for receiving combustion air to be combined with said purified crude coke gas.
