Procedure

The reactor above describes the charcoal production process of the through-feed method. The loading of commodity as well as the discharge of carbonised product takes place continuously.
Benefits of this method are optimal energy efficiency and no need of external energy. Electrical energy, which is very less in comparison to the converted energy, is used only to control the electrical components and to run the aspirator. Process heat, that is required for carbonation, is solely produced by the feed-in material.
This reactor thus differs from other types of its kind, where carbonisation takes place with pre-heated air. A further benefit is the extraction of additional energy sources like wood oil, coal gas and process heat as by-products of the carbonation process.
This kind of processing achieves the highest possible use of raw material with high efficiency.
