The decrease in the yield of biogas in winter months in the usual systems—fixed dome and floating dome types—can be checked by providing insulation on the inner surface of the gas holder. A mathematical model has been developed to study the effect of putting in such insulation. A novel concept of making a shallow solar pond water heater over the gas holder to reduce the heat losses and simultaneously provide water for hot charging is proposed and analysed. Calculations corresponding to a typical winter day at New Delhi have been made for a numerical appreciation of the developed analysis.
