Abstract (Croatian)

U ovom je radu predstavljeno plinsko-turbinsko postrojenje te njegova povijest i razvoj. Opisan je princip rada te su navedene i objašnjene metode za ograničavanja temperature dimnih plinova na ulazu u plinsku turbinu. Izrađen je matematički model u Microsoft Excel-u za osnovno plinsko-turbinsko postrojenje kao i za postrojenje u kojem se dimni plinovi hlade ubrizgavanjem vode. Proračun je proveden za postrojenje koje radi s idealnim plinovima te za postrojenje koje radi s realnim plinovima kao radnom tvari. Predstavljeni su dobiveni rezultati te je napravljena njihova usporedba s postojećim rezultatima dobivenih korištenjem računalnog programu Ebsilon Professional. Dana je usporedba utjecaja promjene opterećenja i temperature okoliša na parametre postrojenja koje radi s idealnim plinovima i postrojenja koje radi s realnim plinovima kao radnom tvari.

Abstract

Gas turbine, its history and development is presented in this thesis. Operating principle and methods for flue gas temperature limitation are explained. Mathematical model for basic gas turbine and gas turbine where flue gases are cooled by water injection are made using Microsoft Excel. Calculation is made for both gas turbine with ideal gases and gas turbine with real gases as operating substance. Results are shown and their comparison with existing results acquired using computer program Ebsilon Professional is given. Effect of load and enviroment temperature change on gas turbine with ideal gases and gas turbine with real gases as operating substance is compared.
