Abstract

L'invention concerne un système d'alimentation de gazéificateur contenant un ensemble tampon recevant un matériau, comme un matériau de cellulose pulvérisé à acheminer vers un gazéificateur, et comportant une structure de prétraitement du matériau à acheminer vers le gazéificateur. Une source de gaz inerte pressurisé est couplée à l'ensemble tampon. Une valve rotative est positionnée par rapport à l'ensemble tampon pour recevoir le matériau de l'ensemble tampon. La valve rotative achemine le matériau vers le gazéificateur et contient un sas de gaz qui empêche le gaz de sortir du gazéificateur.
