The article also proposes a solar-biogas system with a heat accumulator for providing heat to the biogas reactor. As a result of the application of a heat accumulator and a solar collector to this type of biogas plant, a temperature of 52-55 ℃ can be obtained for the thermophilic temperature regime. As a result, it is possible to reduce private energy consumption for biogas production by 30-35%. The goals of the calculation-theoretical studies of the biogas plant in the article are mainly directed to the approximate assessment of their thermal efficiency, taking into account the degree of optimization of the thermal technical parameters.enheat accumulator , solar collector, biogas reactor, biomass, amount of heat, film coating, temperature, time.Article
