The Carbonization stove, which this furnace is ideal equipment for wood briquettes to have anoxic distillation carbonization. Due to its rational structure, the furnace only needs small quantity of heat consumption. It adopted Superheated Stream cooling system, thus can speed up the cooling process, which also greatly increase carbonizing ratio (increased from about 88% to 99%) improve the quality of charcoal, and reduce the production cycling time ( from 24 hours to 6 hours). Its horizontal condenser can retrieve much wood tar.
