| 摘要 |
The invention relates to methods and devices for generating and purifying biogas. Biogas is hereby fundamentally generated from biomass in a fermenter (1), the biogas is divided into a methane gas flow (6) and a weak gas flow (8) by means of a separator stage (2), and the weak gas flow is converted into heat and electrical energy in a cogeneration power plant (4). The invention is characterized in that a variable portion of the raw gas flow can be fed directly into the cogeneration power plant by means of a bypass line (11) bypassing the separator stage. |
