In the gasifier the char powder is mixed with steam, heat is provided indirectly through radiation which enables the chemical reactions that form the energy gas. The heat is generated through combustion of the pyrolysis gas, simultaneously the tars are cracked into harmless components.
The gasifier concept is similar to the well proven technology used when gasifying fossil coal with steam i.e. a steam / char gasifier, with the distinct difference that WoodRoll® gasify a renewable coal!
