A method and an apparatus for producing biogas from organic matter including a container () which is charged with fermentation substrate by a delivery system (). At least one stirring mechanism () is arranged in the container. The feedback value of at least one measurable variable is detected and transmitted to a control unit (). A reference variable is also provided to the control unit. The control unit calculates the deviation of the feedback value from the reference value, and actuating variables which modify the power input of the stirring mechanism and/or the composition of the container contents and/or the flow behavior of the container contents are adjusted as a function of the deviation.

Control of biogas plants

A method and apparatus for producing biogas from organic matter including a container () which is charged with fermentation substrate by a delivery system (), and at least two stirring mechanisms () arranged in the container, the stirring mechanisms having propellers () which are rotated and generate mostly horizontal currents of the fermentation substrate in the container. The propeller diameters, the propeller geometries, and the positions of the propellers in the container are selected such that a shared mixing zone of the medium is generated in the container. Data for determining the mean speed and/or the viscosity of the medium in the mixing zone are detected and transmitted to a control unit () which varies actuating variables which modify the power input of the stirring mechanism into the mixing zone and/or the composition and/or the flow behavior of the container contents.
