LID OF COKE CARBONIZATION FURNACE INSTALLED WITH COMBUSTION CHAMBER FOR GENERATED GAS ON SIDE OF THE CARBONIZATION FURNACE

PROBLEM TO BE SOLVED: To provide the lid of a coke carbonization furnace dissolving problems such as prevention of temperature rise and combustion in the lower part of a gas passway spacial chamber, i.e., a combustion chamber for generated gas in the furnace or around the lower part caused by blowing room temperature air from the side and the upper part of the chamber, generation of bad coke and tar, and the like. SOLUTION: The lid 3 of the coke carbonization furnace is installed with a combustion air feeding nozzle 11 for feeding air from the lower part of the combustion chamber 13 for generated gas in the furnace preheating with a long air feed pipe 12 by introducing required air from an air chamber 17 having an opening-closing plate 23 opening downward and mechanically self driven with sensing the internal chamber pressure of the gas combustion chamber 13 for generated gas in the furnace.
