Analyzing biomass cogeneration plant potential in heating of greenhouses

Cilj ovog Završnog rada je na temelju literature i stvarnog kogeneracijskog postrojenja koje se nalazi kraj Osijeka u selu Nard i radi sa 500 kW električne i 1,8 MW toplinske energije, napravit tehnološku i ekonomsku analizu. U analizi su korištene cijene i podaci iz Hrvatskog i Europskog elektroenergetskog sustava te su detaljno proučeni dijelovi postrojenja i uvjeti koji se u njima javljaju. Iz ekonomske analize dobivena je isplativost projekta uzevši u obzir cijenu investicije, troškove i poticajne cijene. Kao dodatak postrojenju, smišljen je model kojim bi se određena količina CO2 filtrirala i koristila za biljke u plasteniku te je kao profit određena cijena spremnika CO2 koju bi vlasnik morao plaćati da kupuje spremnik CO2 umjesto da ga filtrira iz energane.The purpose of the present work is to present a techno-economic analysis based on literature and a real 500 kWe and 1,8 MWt cogeneration plant located in Nard, a place near Osijek. Parts of the plant and the conditions occurring in them have been studied carefully and an analysis of the system has been carried out while considering prices and statistics from Croatian and European electric power systems. The profitability of the project has been calculated while taking into account the investment price, costs and incentive prices. A model which contains the process of carbon capturing with a purpose to nourish plants that are growing inside the greenhouse has been created. The profit is supposed to be the price of a CO2 tank which the owner would have to buy if he didn’t filter CO2 directly out of the plant
