Abstract:V nalogi je opisana ekonomska upravičenost vlaganja v soproizvodnjo na lesno biomaso. Predstavljen je opis toplotnih potreb hotelskega kompleksa iz katerega smo izračunali toplotne in električne potrebe. Na podlagi urejenega urnega diagrama smo določili potrebno velikost soproizvodne enote in velikosti kotlov za dogrevanje na lesno biomaso in kurilno olje. Ugotovili smo, da je vlaganje v soproizvodno enoto zaradi velikih stroškov investicije zaenkrat še nerentabilno saj je po metodi sedanje vrednosti razlika komaj 221.587,40 EUR. Najboljša rešitev od vseh štirih variant, katere so predstavljene v diplomskem delu je postavitev nove kotlovnice z uporabo kotlov na lesno biomaso s katero bi bistveno zmanjšali tudi onesnaževanje okolja.

Title:ANALYSIS OF ECONOMIC EFFICIENCY OF COGENERATION OF HEAT AND ELECTRICITY WHEN USING BIOMASS AS A FUEL
Abstract:Economic viability of the investment in cogeneration with wood biomass is described in this diploma work. Description of the termal needs of the hotel complex from which thermal and electric needs were calculated is presented. On the basis of an orderly hour chart, determination of the size of cogeneration unit and boilers heating system with wood biomass and fuel oil were determined. We have found that so far investing in cogeneration unit becouse of high costs of investment is loss-making since according to the method mean difference is of only 221.587,40 EUR. The best solution of all four variants, which are presented in the diploma work is to establish a new boiler using biomass boilers which would significantly reduce the environmental pollution.
Keywords:coproduction, cogeneration, wood biomass, cogeneration plants, economic viability, heat.
