A sealed portable industrial furnace for optimizing the concurrent production of charcoal, fuel gas, pyroligneous extract and tar includes an upright metallic body for receiving wood or biomass. A cover is mounted to the upper end of the upright body and the pressure relief system is incorporated into the cover. A perforated base structure is attached to the lower end of the upright body, and a discharge valve is incorporated into the base structure and is closed during production of the charcoal and then is opened to unload the charcoal produced. A support skirt encircles the base structure to support the body in upright position and defines an expansion chamber for the accumulation of combustion gases generated by the furnace. A series of inlet openings are located along the height of the upright body through which combustion air may be introduced under the action of a control system which receives temperate data from temperature monitoring devices located along the height of the body.

This patent of invention is related to a process and a furnace developed for production of charcoal with recovery of gases, tar and pyroligneous extract. The unity system is composed by a metallic furnace, a loading platform, a carbonization platform and unloading platform. For continuous generation of gases, the process operates with multiple carbonization platforms and one or more furnaces for carbonization platform. The furnace is provided with air inputs in strategic side points and mechanism for relieving pressure. The carbonization system is composed by an exhauster, special pipes for conducting the gases, and devices for the recovery of condensable. The gases generated in the process are directed to a burner, a gasifier or directly in a boiler to generate thermal and/or electrical energy. The technology presents, exclusively, a gravimetric yield in fuel gas superior to 60% and a productivity on charcoal above 800 kg/h, so that each operating cycle of the furnace takes less than 5 hours. The coal is discharged hot, after carbonization and loaded on wooden billets immediately after unloading. The process combines technical, economic, operational, and environmentally viable solutions.
