Abstract
Tema ovog diplomskog rada je analiza bazirana na sintezi mreže izmjenjivača topline u termoelektrani Plomin 2. Cilj rada bio je utvrditi racionalnost korištenja energije u predmetnoj termoelektrani. Konstrukcija kompozitnih krivulja toplih i hladnih struja izvedena na kraju analize dovela je do zaključka kako je za ovu konfiguraciju sustava korištenje energije racionalno i optimalno. Dokaz tomu je dobivena minimalna razlika temperatura (pinch točka) u iznosu od 12 C. Posljedica ovako postavljenog sustava je ušteda na pogonskim troškovima. S druge strane, za pretpostaviti je da se ova razlika očitovala u investicijskim troškovima prilikom izgradnje postrojenja. U daljnjoj analizi usvajale bi se niže minimalne razlike temperatura čime bi se mogle ostvariti uštede, ako bi se ekonomski opravdali prateći investicijski troškovi. Analiza bi kao takva već prerasla u optimizaciju sustava što nadilazi okvire ovoga rada. Primarna namjena predmetnog postrojenja je proizvodnja električne energije što se odrazilo na provedbu analize. Snaga koju je potrebno dobiti na stezaljkama električnoga generatora je u jednu ruku ograničavajući faktor promatramo li oduzimanja pare na turbini. S obzirom na to da je električna snaga na stezaljkama električnoga generatora odlučujući faktor, ovakva analiza pronalazi širu upotrebu u raznim procesnim, pektrokemijskim i drugim postrojenjima. Ipak, termodinamički gledano može dati dobru sliku o potencijalu unutarnjih izvora energije te razini iskorištenja istih. Analiza provedena u radu može biti dobar temelj nekoj novoj potencijalnoj razradi sustava.
Abstract (english)
Subject of this master thesis is thermal analysis of thermal power plant Plomin 2. The goal was to identify the rationality of energy use in subject power plant. Construction of composite curves of hot and cold streams, as the end of the analysis, led to the conclusion that the energy use in this system configuration is rational and optimal. The argument is founded minimal temperature difference (pinch) of 12 C. The main effect of such system configuration is saving in operative costs. On the other side, we can assume that this saving effected the amount of capital costs in a way that they were increased. In further analysis, we would accept lower minimal temperature difference which could lead to saving in operative costs, if the following capital costs are economically justified. The analysis would develope into system optimization which is above limitations of this master thesis. Primary purpose of this plant is production of eletrical power which affected the analysis. The electrical power which needs to be generated in the electrical generator restricts the possibilities to configurate steam extractions from the turbine. According to the fact that the electrical power is conclusive factor, this type of analysis would more likely be used in process, petrochemical and other facilities. However, this analysis could define internal heat sources and the level of using them.The analysis made in this master thesis could be good base for new, potential elaboration of subject plant.
