In this case, since the raw chips m are stirred by the screw 53, the raw chips m are well exposed to the combustion gas, so that the carbonization efficiency is improved. The raw material chips m carbonized in the carbonization chamber 20A are supplied to the scouring chamber 2
It descends to 0B and is burned in the scouring chamber 20B.
In this case, air is forcibly supplied from the air supply port 30 via the air supply duct 32 by the air fan 33, and the combustion gas rises toward the upper exhaust port 34. Is sufficiently distributed, the combustion is promoted, and the finishing efficiency of carbonization in the refining chamber 20B is improved. In addition, since a large number of air supply ports 30 are formed around the furnace wall and air can be supplied from each air supply port 30 at a time by the air supply duct 32, the air in the scouring chamber 20B spreads more sufficiently, and combustion is promoted. The finishing efficiency of carbonization in the refining chamber 20B is improved.
