質低下を招くことになるという問題が生じた。In the infusibilizing furnace, hydrocarbon-based vapor pitch is generated from the processing material during the infusibilizing process and is mixed into the circulating air. It had to be replaced with air. However, if the amount of the air to be replaced increases, the amount of contaminated air released from the infusibilizing furnace naturally increases, causing a problem that the exhaust gas processing apparatus for processing the contaminated air must be enlarged, and the like. By reducing the amount of air,
Since a large amount of vapor pitch is contained in the circulating air, there is a problem in that the vapor pitch adheres to the processing material and causes deterioration in the quality of the processing material.
