Title (EN) METHOD AND DEVICE FOR GASIFYING BIOMASS
(FR) PROCEDE ET DISPOSITIF SERVANT A GAZEIFIER UNE BIOMASSE
Abstract: front page image
(EN)Method and device for gasifying biomass in two stages. During a first stage, the biomass, mixed with an auxiliary medium, is exposed to an elevated temperature. In the process, fuel gases are released, as well as a mixture or auxiliary medium and charcoal-like material. The latter is then burned. The heat released is fed to the first stage. An additional stage, in which the tar which is present is separated from the gas production stream, is incorporated between these two stages, making use of the intermediate product, namely charcoal-like material.
(FR)Procédé et dispositif servant à gazéifier une biomasse à deux niveaux. Au premier niveau, on expose la biomasse mélangée à un niveau auxiliaire à une température élevée. Ceci permet de libérer des gaz combustibles, ainsi qu'un mélange ou milieu auxiliaire et un matériau de type charbon. On soumet ce dernier à une combustion. On alimente le premier niveau en chaleur libérée par le processus précédent. Un niveau intermédiaire consiste à séparer le goudron éventuel du flux de gaz de production et à mettre en application le produit intermédiaire, à savoir le matériau de type charbon.
