    • PURPOSE:To inhibit the mixing of a product gas with a combustion gas, ensure the safety and improve heat efficiency, by partitioning a carbonization chamber of a continuous coke oven into a first direct-fire heating zone, a radiant tube heating zone and a second direct-fire heating zone. CONSTITUTION:A carbonization chamber 1 of a continuous coke oven is partitioned into a first direct-fire heating zone 2A, a radiant tube heating zone 6 and a second direct-fire heating zone 2B. A burner in which combustion is performed at a low excess air ratio is used as a burner 5 for each of the direct fire heating zones 2A and 2B. A briquette is fed from a hopper 13 and transferred on a mesh belt 11. During the transfer, heat treatment is conducted, and the combustion gas generated in the direct-fire heating zones 2A and 2B are exhausted from an exhaust part 3. Thus, the product gas formed in the radiant tube heating zone 6 can be discharged through a discharge port 8 without suffering mixing with the combustion gas. Further, even when the portion of the product gas is mixed with the combustion gas, there is no danger of explosion since the combustion gas has a low O2 content.
