Abstract: The process of biogas production from livestock farm waste depends on various technological factors, the main of which is the fermentation temperature. Mesophilic fermentation mode is used in practice for biogas production. The technological process of the methane tank provides for the replacement of part of the fermented mass with fresh biomass several times a day. The temperature of fresh biomass in the cold season is significantly lower than the fermentation temperature. This leads to a decrease in the temperature in the methane tank. Methanogenic bacteria in mesophilic fermentation mode are sensitive to temperature changes. Fluctuations in the fermentation temperature by several degrees can lead to a decrease in the volume of biogas produced. In order to avoid fluctuations in the fermentation temperature in the methane tank after loading a fresh portion of biomass, it is proposed to add a reactor for preheating biomass to the scheme of the biogas plant.
Keywords: digester, biogas, digestion temperature, additional heating.
