Abstract
Zadatak ovog rada je projektirati jedan energetski blok snage 100 MWe koji radi na kombinirani plinsko-parni proces uz korištenje prirodnog plina kao goriva. Prije proračuna, opisano je kako je došlo do kombinarog ciklusa i što njega čini kompetitivnim u odnosu na samostalna plinska i parna turbinska postrojenja. Ukratko je opisan princip rada procesa i svaki njegov osnovni dio je prezentiran kao i načini na koji se povećava njegova učinkovitost. Za proračun izvršen je odabir plinske i parne turbine koje ispunjavaju zadane zahtjeve te su se njihovi poznati radni parametri uzeti za računanje, a oni kojih nije bilo su se pretpostavili uz pomoć dodatne literature. Najvažnije je u proračunu je bilo doći do parametara svih karakterističnih stanja procesa iz kojih se napravila toplinska bilanca i konačno došlo do iskoristivosti cijelog kombi procesa. Bilo je važno pokazati kako je u najkritičnijem području, onom na ulazu zagrijane vode u isparivač, pozitivan temperaturni gradijent, jer da nije proces nebi funkcionirao. To je i grafički prikazano u t-Q dijagramu. Nacrtana je još i idejna shema ovog projektiranog kombiniranog postrojenja i osmišljen je u izvedbi 2x1, dvije plinske turbine na jednu parnu.
Abstract (english)
Mission of this paper was to design and calculate one 100 MW energy block which operate on combined cycle with use of natural gas as fuel. Before calculations, in introduction it's been described how combi cycle came abour and what makes him competitive to single gas and steam turbine systems. The working principle of the process, each of its basic parts, as well as the ways of increasing its efficiency has been described. For the calculation, the selection of gas and steam turbines that meet the required initial requirements and their known working parametets were taken for computation and those that were not are assumed with help of additional literature. The essential thing in the proces was to find parameters of all the characteristic states from which the heat balance was made and ultimately efficiency of entire combined cycle. It was important to show that at the most critical area of the proces, entrance of heated water into evaporator, is a positive temperature gradient, because otherwise it wouldn't work. This is also graphically shown in the t-Q diagram. The conceptual design of this combined working energy block is also drawn and designed in the configuration of 2x1, two gas and one steam turbine.
