Device, use thereof, method and system for continuously converting biomass

摘要

The invention relates to a device (100; 302), the use thereof, a method, and a system (300) for continually converting biomass (102; 304). The device (100; 302) comprises the following: an infeed area (104) for receiving a moving bed from the biomass (102; 304), particularly wood, having an upper segment (140) for drying, a middle segment (142), a flame zone, for degassing, and a lower segment (146), a smoldering zone, for carbonizing the biomass (102; 304) into a solid converted product (158; 306), particularly charcoal; a grate (110) supporting the moving bed and permeable downward for the solid converted product (158; 306). A collection tank (136) for collecting the solid converted product (158; 306) is disposed below the grate (110) and can be coupled to the infeed area (104), gas-tight to the environment, and comprising a wall area having a cooling device (160). The system (300) comprises the device (100; 302), a biogas plant (314) and/or a combined heat and power plant (310), wherein a liquid converted product (156) from the converting of biomass (102; 304), particularly pyroligneous acid or acetic acid, can be fed to the biogas plant (314), and/or the solid converted product (158) from the converting of biomass (102; 304), particularly charcoal, can be fed to a combined heat and power plant (310).
