Project of biogas plant

Poslijednje desetljeće u energetici obilježio je strelovit uspon korištenja obnovljivih izvora energije. Danas obnovljivi izvori energije nisu samo eksperiment već ekonomska realnost koja doprinosi energetskom ostamostaljenju i održivosti. Isplativost svakog energetskog postrojenja ovisi o mnogo čimbenika što dolazi do izražaja upravo kod obnovljivih izvora. Predmet ovog rada je jedno bioplinsko postrojenje dimenzionirano za pokrivanje vršnih potreba za toplinskom energijom 15 gospodarstava u ruralnom području, dok se proizvedena električna energija prodaje u mrežu prema feed-in tarifi. Analiza koja je provedena u ovom radu obuhvača određivanje količinu potrebne sirovine, a tim i veličinu opreme vezanu s bioplinskim postrojenjem. Nakon proračuna i odabira opreme za bioplinsko postrojenje provedena je ekonomska analiza postrojenja. Ekonoskom analizom je prikazana novčana struktura investicije, godišnjeg troška i godišnjeg prihoda, tim podatcima je izračunat povrat investicije.The last decade in energetics was marked by the rise of useing renewable energy. Today, renewable energy is not just an experiment but an economic reality which contributes to energy independence and sustainability. The cost-effectiveness of each energy facility depends on many factors wich comes out precisely in renewable energy resurces. The subject of this work is a biogas plant that is sized to cover peak demand for heating energy of 15 farms in rural area, while the electricity produced is sold in eletrical grid by price of feed-in tariff. The analysis conducted in this paper includes the determination of the amount of necessary raw materials, and the size of the equipment for the biogas plant. After calculation and selection of equipment for biogas plant an economic analysis of the plant is conducted. Economic analysis shows the financial structure of the investment, annual cost and annual income, with this data the return on investment was calculated
