Abstract: The methods of the exergic analysis of different circuits of biogas power plants that allow for the replacement of the traditional types of energy and improvement of the environmental conditions have been presented. Schematic heat diagrams of biogas units have been proposed and their efficiency has been analyzed. The cycle parameters of different biogas units (gas turbine unit, steam gas unit with the gas vent to the boiler and the steam gas unit with high temperature steam generator and intermediate steam overheating have been compared and their exergic characteristics have also been compared The exergic analysis proved that the cycle of the biogas steam gas unit with the intermediate steam overheating using the high –pressure steam generator is the most efficient, which is explained by the fact that the fraction of the thermal energy of combustion products for the steam cycle and gas cycle is approximately the same in contrast to traditional steam and gas units.The methods of the exergic analysis of different circuits of biogas power plants that allow for the replacement of the traditional types of energy and improvement of the environmental conditions have been presented.
