A coke oven that is equipped with a furnace lid, then charges coal into the carbonization chamber through the furnace top coal charging hole, and carbonizes waste tires together with the coal, thereby recovering and using it as fuel gas without controlling the coke production amount. A method for operating a coke oven that can increase generated gas at low cost has been provided.

る。In order to charge the above waste tires into the carbonization chamber, the red-hot coke in the carbonization chamber is extruded using an extruder. A donut-shaped rolling guide for waste tires is installed between the working floor and the working floor, and the waste tires are placed on the rolling guide from the working floor, and rolled on the slope of the rolling guide into the carbonization chamber. Normally, in order to increase the gas produced by a coke oven, waste tires are repeatedly placed on a rolling guide, and as many waste tires as possible are charged into the carbonization chamber. .

In the process until the furnace lid is attached to the coke extrusion port, soot-containing gas is generated from the waste tires that are rolling in the coking chamber, and soot-containing gas is also generated from the discarded tires that have already stopped being charged into the coking chamber. However, there is a problem that the coke is radiated outside the furnace from the upper part of the coke extrusion port, causing air pollution.
