SUBSTANCE: biogas unit contains heat insulated methane tank, consisting of an extruder mixer, electric biomass mixers, pumps, chambers of hydrolytic, acid and methane fermentation, each is fitted with a heat exchanger. To the outlet of the methane tank, to the methane fermentation chamber the gas-holder and the fermented mass separator are connected. The biogas unit is fitted with the unit of sources of renewable and other currently excessive energies in networks. The unit of sources of renewable and other excessive energies comprises the thermal accumulator fitted with heat exchangers, fire-bar elements and a generator; this thermal accumulator is connected to sources of renewable energy and mains. Meanwhile the heat accumulator inlet for make-up water is connected to the line, and hot water outlets of the heataccumulator are connected to an extruder mixer and fermentation chambers. Heat accumulator's fire-bar element by means of electric energy switches is connected to electric mixers, pumps and the extruder mixer or to the generator with a possibility of operation of the latter from the sources of renewable energy or in case of their absence - from the mains during the time period of low tariffs for payment of the electric power.
EFFECT: increase in biogas production due to providing the optimum modes of continuous fermentation of biomass in zones of cold climate with the long heating period.
