Provided is a fixed carbon production device excellent in operation stability and safety which has high strength and may have a compact device volume, which makes possible production of high-quality fixed carbon with high yields and in large amounts, which is capable of keeping the dry distillation temperature low, which has few restraints in the compositional material, which, having a low dry distillation temperature and low heat input amount, has excellent energy-saving efficiency, and which is capable of solving problems due to a tar component. This fixed carbon production device is provided with: a quench chamber for collecting fixed carbon; a dry distillation furnace which is erected and fixed in the quench chamber and into which raw material coal is fed; a dry distillation unit which is polygonal in horizontal cross-section and is partitioned by a separating wall which partitions the inside of the dry distillation furnace in the vertical direction; a dry distillation mini-furnace which is polygonal in horizontal cross-section and which is partitioned by a partition which partitions the inside of the dry distillation unit in the vertical direction; a pipe-shaped heating means which is arranged on the separating wall of the dry distillation unit and the partition of the dry distillation mini-furnace and which dry-distills the raw material coal; and a collection path for collecting fixed carbon collected in the quench chamber. |
