Steam drying offers the prospect of higher efficiency in comparison to air‐drying. Having solved the technical problems, the steam drying of wood chips in industry is now possible. The system presented here allows a saving of around 10 % of the thermal energy required in a wood chip drying process. The significant reduction of emission levels, relating to total carbon, of about 98 % is guaranteed by the integrated vapor treatment.
