WASTE TREATMENT METHOD, METAL MANUFACTURING METHOD AND METAL

摘要

PROBLEM TO BE SOLVED: To provide a waste treatment method using a rotary kiln and capable of elongating the service life of a kiln main body by suppressing fluctuation of the combustion state due to variation of waste.

SOLUTION: In the waste treatment method using the rotary kiln 1, waste and water-containing sludge are input to the kiln main body 2 of the rotary kiln 1, and internal temperature of the kiln main body 2 is measured. Based on the temperature data, at least one of the input amount of the water-containing sludge and the input amount of the waste to inside of the kiln main body 2 is adjusted to control temperature distribution inside the kiln main body 2.
