PROBLEM TO BE SOLVED: To provide the lid of a carbonization furnace having a combustion chamber for a gas generated within the furnace into which a necessary amount of air for combusting the gas generated in the furnace is blown by automatic control without depending on electrical control. SOLUTION: The lid 3 of the carbonization furnace has the combustion chamber 13 for the gas generated within the furnace on the side of the carbonization chamber. The vertical pipe 18 of a T-shaped three-way pipe 17 on the lid has an air inlet opening 20 on one side wall 19 inclining to the inside from the upper side, an air inlet pipe 21 of a slant path having a front end downward outside of the air inlet opening 20 and an air chamber 16 suspended with a downward open closing plate 22 of the air inlet opening 20 in the inside, and an open/close lid for discharging coal dust is installed at the lower end of the vertical pipe 18. Further, an automatic control nozzle 11 for feeding combustion air having a vertical pipe 12 housed in the combustion chamber 13 for the generated gas is installed to the front end of a horizontal pipe 24 through an open/close valve 25 by bringing the upper side to a convergent nozzle 26 for jetting air and the lower side as an opening 27 for falling the coal dust.
