Abstract

Selon l'invention les cendres, notamment destinées à alimenter un gazéificateur à lit entraîné, sont acheminées via un sas à hautes pressions de 40 à 100 bar, l'augmentation de pression étant obtenue à un premier étage de pression par une pompe à cendres (2) et à un deuxième étage de pression par un sas à cendres (3), les cendres apportées sous pression étant cédées à un récipient doseur (4). Dans le récipient doseur (4), un lit fluidisé partiel est généré par une alimentation en gaz de tourbillonnement et gaz de transport par une conduite (10), les conduites de transport (11) conduisant à un consommateur, par exemple un réacteur destiné à la gazéification sous pression de cendres.
