Abstract
Tema ovog rada je idejni projekt bioplinskog postrojenja. Bioplin je goriva smjesa plinova od koji su dva najvažniji CH4 i CO2. Spada u obnovljive izvor energije jer se dobiva se anaerobnom digestijom, odnosno razgradnjom organskih tvari bez kisika. Kao sirovina koristio bi se gnoj s 15 farmi pilića i ostaci od branja kukuruza u zrnu. Na godišnjoj razini može se dobiti 2 100 t gnoja i 900 t ostataka. Prema bioplinskom kalkulatoru može se dobiti 1 021 545 m3 bioplina. Predviđa se iskorištavanje bioplina u motor generatoru za dobivanje električne i toplinske energije. Električna energija bi se isporučivala u mrežu dok bi se dio toplinske iskoristio za grijanje digestora, a ostatak predao u okolinu. Ekonomskom analizom pokazano je da takvo postrojenje s trenutnim troškovima investicije, cijenom električne energije i sl. nije isplativo.
Abstract (english)
The topic of this paper is the conceptual design of a biogas plant. Biogas is a flammable mixture of gases, the two most important of which are CH4 and CO2. It is a renewable energy source because it is obtained through anaerobic digestion, i.e. decomposition of organic substances without oxygen. Manure from 15 broiler farms and residues from harvesting corn in grain would be used as a feedstock. 2,100 t of manure and 900 t of residues can be obtained annually from which 1 021545 m3 of biogas can be generated. It is planned to use biogas in a motor-generator to obtain electrical and thermal energy. The electrical energy would be delivered to the grid, while part of the thermal energy would be used to heat the digester, and the rest would be released into the environment. The economic analysis showed that such a plant with the current investment costs, the price of electricity, etc. is not profitable.
