There has been a worldwide increase in the demand for energy. The major part of this energy demand is being met by the combustion of fossil fuels which has resulted in their price rise. The utilization of fossil fuels has also put across pressing challenges to the society like climate change, pollution and public health hazards, and energy poverty; making the greening of the energy sector an imperative change. It has long been recognized that the sunlight falling on the earth’s surface is more than adequate to supply all the energy that human activity requires. Therefore, in this communication, an analytical expression for slurry temperature (Ts) for an active N- flat plate collector's (N-FPC's) integrated biogas plant has been derived for conducting exergy analysis. The calculations were performed by using MATLAB 2010a. In this study, it was found that the maximum annual exergy for flat plate collector and slurry were obtained for the months of June and July. The influences of various design parameters such as the mass of the slurry (Ms), the length of the collector pipe (L), the number of collectors in series (N) and the mass flow rate of the slurry ; on slurry temperature has been studied for an optimum slurry temperature ( ). Further the above parameters have also been optimised to design an active system for the heating of the slurry. This flat plate collector integrated biogas plant has been observed to be self sustainable and showed a superior performance as compared to a simple biogas plant.
