EXERGO ECONOMIC ANALYSIS OF ORGANIC RANKINE CYCLE BASED ON GEOTERMAL POWER PLANET

U ovom diplomskom radu analiziraju se mogućnosti upotrebe Rankineovog ciklusa s organskim fluidom (ORC-Organic Rankine Cycle) za proizvodnju električne energije iz geotermalnog izvora topline. Definirani su matematički modeli za termodinamičku, eksergetsku, ekonomsku i eksergoekonomsku analizu i optimiranje danog ORC postrojenja. Navedene analize i optimiranja provedene su korištenjem programskog paketa EES (Engineering Equation Solver). Proračuni su provedeni za četiri odabrana radna fluida. Analizom dobivenih rezultata dobivene su informacije o najboljim pogonskim i konstrukcijskim karakteristikama za danu konfiguraciju ORC postrojenja.This thesis analyzes the possibilities of using the Rankine cycle with organic fluid (ORC - Organic Rankine Cycle) to produce electricity from a geothermal heat source.Mathematical models for thermodynamic, exergetic, economic and exergoeconomic analysis and optimization of a given ORC plant are defined. These analyzes and optimizations were performed using the software package EES (Engineering Equation Solver). Calculations were performed for four selected working fluids. The analysis of the obtained results provided information on the best operating and construction characteristics for a given configuration of the ORC plant
