Abstract:
1. Biogas installation for production of biogas having at least one fermenter which operates on the principle of dry fermentation for production of biogas in the batch mode with a biogas outlet and a purging gas inlet; a biogas line that can be connected to the biogas outlet; an off-gas line by means of which off-gas containing carbon dioxide can be supplied to the purging gas inlet; an off-gas chimney which can be connected to the biogas outlet via a first biogas/off-gas line; an off-gas flare which can be connected via a second biogas/off-gas line to the biogas outlet; a fresh air line which can be connected to the purging gas inlet; a control device configured to a measurement device which is connected to the control device and has a first measurement sensor for detection of the methane concentration and a second measurement sensor for detection of the carbon-dioxide concentration in the gas mixture emerging from the at least one fermenter.
