Title
(EN) ARRANGEMENT AND SYSTEM FOR A TREATMENT PROCESS
(FR) AGENCEMENT ET SYSTÈME DESTINÉS À UN PROCÉDÉ DE TRAITEMENT
Abstract
(EN)
A system for feeding lignocellulosic biomass material, comprising a pre- compressing stage for receiving biomass material and pre-compressing the material at a first pressure and a first compression ratio. A plug screw feeder receives the pre-compressed material and feeds the material against a second pressureand a second compression ratio, wherein the plug screw feeder includes a variable speed plug screw arranged in the plug screw feeder connected to a variable speed plug screw power source.
(FR)
L'invention concerne un système d'alimentation en matériau de biomasse lignocellulosique, comprenant un étage de pré-compression permettant de recevoir un matériau de biomasse et de pré-comprimer le matériau à une première pression et un premier rapport de compression. Un dispositif d'alimentation à vis à bouchon reçoit le matériau pré-comprimé et introduit le matériau à l'encontre d'une seconde pression et d'un second rapport de compression, le dispositif d'alimentation à vis à bouchon comprenant une vis à bouchon à vitesse variable agencée dans le dispositif d'alimentation à vis à bouchon relié à une source d'alimentation à vis à bouchon à vitesse variable.
