Abstract (Croatian)

Cilj ovog rada bio je napraviti matematički model plinskoturbinskog postrojenja i matematičke modele s poboljšanom termodinamičkom iskoristivošću koristeći program EBSILON Professional. Napravljena su tri matematička modela od kojih je prvi osnovni model plinskoturbinskog postrojenja. Drugi model je s izmjenjivačem otpadne topline, gdje se toplina na izlazu iz plinske turbine iskorištava za zagrijavanje zraka u izmjenjivaču prije ulaska u komoru izgaranja, a u trećem modelu koristi se ubrizgavanje vode u dimne plinove. Napravljena je detaljna analiza svih bitnih parametara koji utječu na iskoristivost postrojenja kao što su tlak, temperatura i maseni protok. Kroz niz simulacija u zadanom programskom paketu obuhvaćeni su svi relevantni parametri te je pokazano kako i u kojoj mjeri utječu na iskoristivost u određenim režimima rada. Dijagrami i rezultati su dobiveni pomoću paketa EBSILON Professional i Microsoft Excel.

Abstract

The aim of this assignment was to make a mathematical model of a gas-turbine power plant and mathematical models with improved thermodinamic efficiency using the EBSILON Professional program. Three mathematical models have been made, of which the first was basic model of a gas-turbine plant. The other model is with a heat exchanger of exhaust gases, where heat from gas turbine outlet is used for heating air in heat exchanger before entering the combustion chamber, and the third model uses injecting water into flue gases. A detailed analysis of all the essential parameters affecting plant efficiency such as pressure, temperature and mass flow has been made. Through a series of simulations, all relevant parameters are covered by the default program package, and it shows how and to what extent they affect the efficiency of certain operating modes. Diagrams and results were obtained using EBSILON Professional and Microsoft Excel.
