Abstract

L'invention concerne une méthode de recyclage dans un procédé de gazéification de la chaleur perdue générée par un procédé externe, alimenté par du gaz de synthèse, afin d'améliorer la densité d'énergie du gaz de synthèse produit ainsi que l'efficacité globale de gazéification du système. La méthode concerne l'utilisation de la chaleur perdue contenue dans un flux sortant du procédé alimenté par du gaz de synthèse pour vaporiser de l'eau et produire de la vapeur. La qualité de la vapeur est ensuite améliorée, d'abord en échangeant de l'énergie avec le gaz de synthèse chaud sortant du gazogène, et ensuite à l'intérieur du gazogène lui-même, pour atteindre une température à laquelle la gazéification à la vapeur de la biomasse se déroule de façon significative. Le procédé à l'intérieur du gazogène est démarré par l'introduction d'une petite quantité d'air dans le gazogène pour qu'une partie de la biomasse entre directement en combustion et fournisse la chaleur requise par le procédé.
