Working Process of Continuous Charcoal Furnace

How to produce a large number of high-quality charcoal? Continuous carbonization furnace is the best choice. It uses anaerobic carbonization technology to change biomass into charcoal. Biomass includes the materials like wood chips, sawdust, rice hull, plant straw, bamboo, coconut shell, palm shell, etc.

1. Pretreat biomass less than 50mm by crushing machine.

2. Biomass pretreated is fed into drying system by automatic conveying system. Fuel of our drying system sources from flue gas waste heat produced biomass carbonization process. Hot air is lead into dryer. Raw material is dried step by step, with mode of screw-feeding and batch splitting.

3. Then the biomass dried will automatically fall into continuous carbonization furnace. Temperature for carbonization is about 400 to 600 degree Celsius. The higher the temperature, the greater the yield; the faster the carbonization rate, the lower the operation cost.

4. Charcoal will be discharged and collected by professional equipment after through water cooling system. Temperature of charcoal discharged is about 30 degree Celsius. Biogas is collected by special equipment after it has been purified with dry or wet multistage purification, or it can be recycled as fuel for heating carbonization furnace. Wood tar and wood vinegar are collected by professional collecting system.
