Abstract
Ovaj rad fokusiran je na termodinamičku i ekonomsku analizu i optimizaciju organskog Rankineovog ciklusa za geotermalnu elektranu. Analiza je provedena za slučaj geotermalnog polja Rečica u blizini Karlovca. Termodinamička i ekonomska analiza provedena je za osam radnih fluida [R134a, isobutane, R245fa, R601, R601a, R290, R1234yf, and R1234ze(E)], u ovisnosti o utjecaju temperature odnosno tlaka isparavanja, temperature i tlaka kondenzacije te temperaturne razlike fluida u isparivaču i kondenzatoru, na vrijednosti kao što su neto snaga i ireverzibilnost. Ekonomska analiza bazirana je na odnosu neto dobivene snage i ukupnih troškova postrojenja. Analiza i optimizacija pokazale su da najbolje ekonomske performanse imaju n-pentane i isopentane, dok R1234yf i R290 imaju najbolje termodinamičke performanse. Analiza je pokazala da je geotermalna elektrana s podkritičnim organskim Rankineovim ciklusom mogući i obećavajući način proizvodnje električne energije.
Abstract (english)
This paper is focused on the thermodynamic and economic analysis and optimization of an organic Rankine cycle based geothermal power plant. The analysis is applied to a case study of the geothermal field Rečica near the town Karlovac. Thermodynamic and economic performance of an organic Rankine cycle geothermal power plant is conducted using 8 working fluids [R134a, isobutane, R245fa, R601, R601a, R290, R1234yf, and R1234ze(E)]. The thermodynamic analysis is performed on the basis of the analysis of influence of the operation conditions, such as evaporation and condensation temperatures and pressures, and evaporator and condenser pinch point temperature difference, on the cycle characteristics such as net power output, and plant irreversibility. The economic analysis is performed on the basis of relationship between the net power output and the total cost of equipment used in the organic Rankine cycle. The analysis reveals that the working fluids, n-pentane and isopentane, show the best economic performances, while the working fluid R1234yf and R290 have the best thermodynamic performances. Analysis results demonstrate that the subcritical organic Rankine cycle geothermal power plant represents a promising option for electricity production application.
