METHOD FOR OPERATING COKE OVEN IN WHICH IN-OVEN GAS COMBUSTION CHAMBER IS DISPOSED ON CARBONIZATION OVEN SIDE OF OVEN LID

PROBLEM TO BE SOLVED: To provide a method for operating a coke oven, increasing the carbonization rate of coal particles 2 charged on the carbonization oven side in an in-oven gas combustion chamber 13 attached to the carbonization oven side of the oven lid 3, and preventing the overheating and small explosion phenomenon of the coal particles 3 due to the supply of an unnecessary amount of air. SOLUTION: This operation method is characterized by closing an air-supplying valve 18 connected to the air-supplying side of an in-oven gas combustion air supply amount-controlling nozzle 17 disposed on the carbonization oven side of the oven lid 3 from the coke carbonization oven 1 for carbonizing the coal particles 2 and used for supplying air in an amount necessary for burning an in-oven gas flowed in the in-oven gas combustion chamber 13, in a carbonization end time when H2gas component in the in-oven gas flowed in the carbonization oven 1 or the in-oven gas combustion chamber 13 rapidly increases or when CH4gas rapidly decreases.
