본 발명은, 고수분율 바이오매스의 건류에 의한 탄화처리를 기존의 탄화장치에 대폭적인 개량을 가하지 않고 효율적으로 할 수 있는 탄화방법을 제공한다. 본 발명의 탄화방법은, 저수분율 바이오매스를 탄화로 내에서 열분해시켜서 저수분율 바이오매스 유래의 탄화연료와 건류가스를 얻는 제1공정, 얻은 건류가스의 2차연소에 의하여 얻은 고온가스에 의하여 건조기 내의 고수분율 바이오매스를 건조시켜서 건조 바이오매스를 얻는 제2공정, 제2공정에서 얻은 건조 바이오매스를 보관하는 제3공정으로 이루어지는 3개의 공정을 일정기간 연속하여 실시하고, 그 후에 보관한 건조 바이오매스를 열분해시켜서 고수분율 바이오매스 유래의 탄화연료와 건류가스를 얻는 제4공정, 얻은 건류가스의 2차연소에 의하여 얻은 고온가스에 의하여 건조기 내의 고수분율 바이오매스를 건조시켜서 건조 바이오매스를 얻는 제5공정, 제5공정에서 얻은 건조 바이오매스를 보관하는 제6공정으로 이루어지는 3개의 공정을 일정기간 연속하여 실시한다. The present invention provides a carbonization method that can efficiently perform a carbonization processing using dry-distillation of high moisture biomass without adding a major improvement to an existing carbonization apparatus. The carbonization method of the present invention in which three processes are performed continuously for a predetermined period which including: a first process of obtaining low moisture biomass-origin carbonization fuel and dry-distilled gas by thermally decomposing low moisture biomass in a carbonization oven; a second process of obtaining dried biomass by drying high moisture biomass in a drying machine using high-temperature gas obtained by secondary combustion of the dry-distilled gas obtained in the first process; and a third process of storing the dried biomass obtained in the second process, and thereafter three processes are performed continuously for a predetermined period which includes: a fourth process of obtaining high moisture biomass origin-carbonization fuel and dry-distilled gas by thermally decomposing the stored dried biomass in the same carbonization oven as the one used in the first process; a fifth process of obtaining dried biomass by drying high moisture biomass in the drying machine using high-temperature gas obtained by secondary combustion of the dry-distilled gas obtained in the fourth process; and a sixth process of storing the dried biomass obtained in the fifth process.
