The invention relates to a feed system for a continuous digester where at least 2 pumps are arranged in parallel in the bottom of a pre-treatment vessel and a liquid level of at least meters is established. The invention makes it possible to provide a feed system with an improved accessibility and more reliable operation, and to operate the main part of the pumps at optimal efficiency even if the production capacity is reduced.
L'invention concerne un système d'alimentation pour un digesteur continu, comportant au moins deux pompes disposées en parallèle dans le fond d'une cuve de prétraitement, un niveau de liquide d'au moins deux mètres étant établi. Le système d'alimentation selon l'invention présente une meilleure accessibilité et un fonctionnement plus fiable, et permet d'exploiter la majeure partie des pompes avec un rendement optimal, même en cas de capacité de production réduite.
