It is the most demanding and advanced carbonization technology worldwide due to its ease of operation, high production efficiency, and good safety. Agricultural biomass or forestry waste is loaded in the front-opening trolley, and after a sufficient retention time, biochar or charcoal is produced with abundant syngas, which can further be used for heating the chamber. The flue gas can be used to dry the biomass.
