Abstract (Croatian)

U ovom radu opisan je i analiziran kombinirani proces u kojemu se otpadna toplina iz plinsko-turbinskog ciklusa koristi kao ogrjevni spremnik za potrebe parno-turbinskog Organskog Rankineovog ciklusa. Nakon opisa osnovnih kružnih procesa, objašnjen je Organski Rankineov ciklus i specifikacije radnih medija koje se koriste. Matematičkim modelom opisan je Braytonov proces s dvostupanjskom kompresijom i dvostupanjskom ekspanzijom te Organski Rankineov ciklus. Analiza rezultata pokazuje kako vrsta radnog medija, temperatura na ulazu u plinsku turbinu i tlak u Organskom Rankineovom ciklusu utječu na termodinamičku iskoristivost kombiniranog postrojenja.

Abstract

Within the scope of this Master Thesis a combined cycle is described and analyzed in which waste heat from a gas turbine cycle is used as a heating reservoir for the steam turbine organic Rankine cycle. Brayton and the organic Rankine cycle are described as well as the properties of the organic fluid which are used as working fluids. A mathematical model is made for the organic Rankine cycle and a two stage compressor and turbine Brayton cycle. The analysis of results show how the type of working fluid, the inlet temperature in the gas turbine and the pressure in the organic Rankine cycle influence the thermodynamic efficiency of the combined cycle.
