摘要

The procedure for the operation of a biogas power station (1), comprises initiating burning stage of the biogas power station from a gas supply, thermally initiating an operational biogasification process by a part of the produced heat in the initiating phase, entirely supplying a heat portion of the waste heat of the initiating phase to a fermenter of a biogas plant (3), and switching the biogasification process gradually by continuously increasing the mixing of the actually produced biogas to the removed gas from the gas supply. The excess heat energy is fed into the biogasification process. The procedure for the operation of a biogas power station (1), comprises initiating burning stage of the biogas power station from a gas supply, thermally initiating an operational biogasification process by a part of the produced heat in the initiating phase, entirely supplying a heat portion of the waste heat of the initiating phase to a fermenter of a biogas plant (3), and switching the biogasification process gradually by continuously increasing the mixing of the actually produced biogas to the removed gas from the gas supply. In the operation of the biogas power station, the excess heat energy from the generation of electricity is fed into the biogasification process and/or a local heat supply network for the operation of direct hot water heating. A part of the heat resulting in the biogas power station and in the biogasification plant is returned into the fermentation process. A fermentation substrate (6) is mixed with wood components and then the fermentation substrate/wood mixture are dried by the surplus waste heat and/or partial waste heat of the biogas power station or the fermenter and supplied to a biomass carburetor like a wood-carburetor. The gas is supplied to the burning process and the resulting ashes are supplied as fertilizers for agricultural use. The fertilizers are recycled on the biomass areas, on which the biomass is brought for biogas and/or wood carburation. The waste heat, which results in all process steps and in the biogas power station and the biogasification plant, is flowed into a heat turbine. An independent claim is included for a biogas power station.
