摘要

The method for combined energetic utilization of biomass (6) e.g. liquid manure for generation of current and heat, comprises parallely operating a biogas plant (1) and a wood-gasification plant, injecting the produced and processed biogas in the biogas plant into a gas supply network (2), and withdrawing the injected gas to another place of the gas distributor network to operate a thermal power station (3), with which current and heat are produced. A boiler for producing steam is connected downstream of the combustion plant and/or the wood gasification plant. The method for combined energetic utilization of biomass (6) e.g. liquid manure for generation of current and heat, comprises parallely operating a biogas plant (1) and a wood-gasification plant, injecting the produced and processed biogas in the biogas plant into a gas supply network (2), and withdrawing the injected gas to another place of the gas distributor network to operate a thermal power station (3), with which current and heat are produced. A boiler for producing steam is connected downstream of the combustion plant and/or the wood gasification plant. An electrical energy is generated with the steam by a steam turbine (7) and a steam motor and is injected into a power supply system. A gas cleaner is connected downstream of the wood gasification plant and subsequently the gas drives in a combustion motor. The resulting heat is used for heating the bioreactor of the biogas plant, for heating purposes and/or for drying the biomass. The electrical energy is produced from the combustion motor and is injected into a power supply system.
