Abstract

La présente invention concerne des procédés de séchage de matières lignocellulosiques consistant d'abord à fournir un gaz combustible chaud d'une chambre de combustion, à refroidir ce gaz combustible chaud, à mélanger ensuite le gaz combustible partiellement refroidi avec de l'air froid, à sécher les matières lignocellulosiques avec le gaz combustible ainsi refroidi pour obtenir un gaz de combustion, à recirculer une partie du courant de gaz de combustion vers la chambre de combustion, et enfin, à recirculer une autre partie du gaz de combustion pour refroidir le gaz combustible chaud.
