Abstract

L'invention concerne un système d'alimentation contenant un ensemble tampon recevant un matériau à acheminer vers un gazéificateur. L'ensemble tampon possède une structure assurant le prétraitement du matériau à acheminer vers le gazéificateur. Une valve rotative est positionnée par rapport à l'ensemble tampon pour recevoir le matériau de l'ensemble tampon. Un autoclave reçoit le matériau de la première valve rotative, la valve rotative acheminant le matériau vers l'autoclave et contenant un sas de gaz qui empêche le gaz de sortir de l'autoclave. L'autoclave peut fonctionner comme un séchoir et un gazéificateur selon ses paramètres d'exploitation.
