NOVELTY - The method for the power generation in biogas plants by treating mixture of silage material via machine mixture and by intermediate storage of the materials, comprises mixing cut, solid plant materials with plant suspensions serving as lubricant by technical regulations of the supply and mixture procedures, and detecting the filling level of the mixture in the mixing component group (4), where the filling level acts as control value for the supply the mixing components. The supplied quantity of the plant material is determined per unit time during supplying.    USE - Method for the power generation in biogas plants by treating mixture of silage material via machine mixture.    ADVANTAGE - The method provides optimal power generation by efficient processing and temporary storage of mixing material for optimal energy output with low technical expenditure.    DETAILED DESCRIPTION - The method for the power generation in biogas plants by treating mixture of silage material via machine mixture and by intermediate storage of the materials, comprises mixing cut, solid plant materials with plant suspensions serving as lubricant by technical regulations of the supply and mixture procedures, and detecting the filling level of the mixture in the mixing component group (4), where the filling level acts as control value for the supply the mixing components. The supplied quantity of the plant material is determined per unit time during supplying and the determined values act as control value for the supply quantity of the suspension to reach the predetermined mixing proportion to the plant suspension. The supplied quantity on plant suspension is determined per unit time during supplying and the determined values act as control value for the supply quantity of the plant material to reach the predetermined mixing proportion to the plant material. The flow rate of the mixtures is determined during continuous pressure-flow in a transport line (9) downstream to the mixture forming group and deviations of the predetermined value are signaled through a tolerance range. A parallelly arranged additional transport line (9) is connected for avoiding the back pressure caused by supplying high quantity suspensions and/or blockages of the transportation lines. The biogas produced by the biogas plant is led during damage occurrence in energy converting component groups, a gas storage and/or an additional energy converting component group. A regulation of the supply of the biogas-producing substances is carried out and the temperature of the ferments is maintained on a level intended for storing the biogas and/or for the energy conversion. The biogas quantity is supplied to the gas storage and/or the additional energy converting component group. An INDEPENDENT CLAIM is included for a device for the power production in biogas plants.
