PP-III-81GENERATION OF ELECTRIC ENERGY FROM THEAGRICULTURE WASTEMaximov A., Degtev M., Ilarionov S.Perm State University, Perm, Russia, htb03_starosta@rambler.ruThe increased requirements to protection of environment against pollution, andthe increasing cost of waste processing have revived interest to anaerobic treatmentof agriculture waste.Production of biogas as an intermediate energy carrier is economically justifiedand it is preferable in processing of constant waste supply, e.g. drains of cattlebreedingand poultry-farming farms, slaughterhouses, vegetative waste, etc.Economic efficiency is connected with absence of the stages of gathering the wastes,and also with constancy of their structure and quantity.Biogas is produced with the plants of different types and size. This process isespecially effective in agriculture where there is a possibility of a full ecological cycleand, for example, sludge remaining after biogas generation is a valuable organicfertilizer [1].The biogas is obtained as a result of anaerobic digestion of agricultural wastes. Itcan be used for heating, cooking, etc, but the conversion of biogas into electric one ismost interesting from the practical point of view. [2]Electric can be generated with the help of a gas generator based on an internalcombustion engine. This energy can also be generated by using fuel cells of variousdesign.The developed and tested pilot plant for the generation of electric energy from aliquid and semi fluid waste of livestock farming consists of a preliminary acidfermentation fermenter, a basic methane-tank fermenter, a gas receiver and a gasgenerator Green Power CC1500. The preliminary acid fermentation fermenter is a3,0x2,0x0,5 m steel bath; and the basic methane-tank fermenter is 3.2 m 3 . A schemeof the biogas pilot plant can be seen in fig.1.592
