Heat Balance of Methane Tank and Calculation of Heat Waste Recovery

Abstract

The article considers thermal balance of the methane tank in the biogas digester, as well as the computation methods of its components and the derived results. Formulae determining the daily losses and expenditures of heat energy in a methane tank have been proposed. They can be used for the development and design of biogas plants with positive energy balance providing the maximum marketable biogas generation. Appropriate diagrams have been presented for the analyses of heat losses and expenses and for introducing research and practical recommendations on their changes.
