Abstract
U ovoj doktorskoj disertaciji istraženo je i analizirano brodsko parnoturbinsko postrojenje s ugrađenim postrojenjem za uplinjavanje na brodu za prijevoz ukapljenog prirodnog plina. Provedena je energijska i eksergijska analiza brodskog parnoturbinskog postrojenja tijekom procesa uplinjavanja na plutajućem plinskom iskrcajnom terminalu. Istraživanje u sklopu doktorske disertacije obavljeno je na nekoliko različitih plutajućih plinskih terminala, a rezultati su praćeni tijekom iskrcaja od početka 2014. do kraja 2020. godine. Kod procesa uplinjavanja, morska, slatka ili destilirana voda koristi se kao izvor topline i prolazi kroz visokotlačni isparivač prirodnog plina, u kojem ukapljeni prirodni plin prelazi u plinovito stanje. Predložen je i proračunan hibridni energijski sustav s gorivnim člankom s krutim oksidom koji se sastoji iz dva dijela. Glavna je komponenta prvog dijela sklop gorivnog članka s krutim oksidom, a glavna komponenta drugog dijela je generator pare. Predloženi hibridni energijski sustav imao bi primjenu u pogledu smanjenja emisije štetnih ispušnih plinova te u pogledu povećanja ekonomičnosti i učinkovitosti. Identificirani su utjecajni parametri na ekonomičnost primjene sustava (promjena cijene goriva, cijena koštanja uređaja, promjena propisa o dozvoljenim emisijama štetnih ispušnih plinova...) i obavljena analiza osjetljivosti na promjene tih ulaznih parametara. Prilikom definiranja i analize sustava gorivnih članka s krutim oksidom, dimenzionirao se sustav koji bi zamijenio tri postojeća turbogeneratora ukupne nominalne snage od 11100 kW. Na temelju dobivenih rezultata provedenih istraživanja zaključeno je pri kojim uvjetima rada novi hibridni sustav povećava učinkovitost za 12 % i smanjuje emisije ispušnih plinova između 72.56 % i 81.64 %, ovisno o iskrcajnim protocima stlačenog prirodnog plina.
Abstract (english)
In this doctoral thesis was researched and analysed a steam turbine propulsion plant with installed re-gasification system on LNG carrier. An energy and exergy analysis of the ship's steam turbine plant during the re-gasification process at the floating gas discharge terminal was carried out. The research as part of the doctoral dissertation was carried out on several different floating gas terminals, and the results were monitored during cargo discharge from the beginning 2014 to the end of 2020. In the re-gasification process, sea, fresh or destillated water is used as a heat source and passes through a high-pressure vaporizer, in which liquid natural gas changes to a gaseous state. A hybrid energy system with a solid oxide fuel cell consisting of two parts is proposed and calculated. The main component of the first part is the solid oxide fuel cell assembly, and the main component of the second part is the steam generator. The proposed hybrid energy system would have applications in terms of reducing the emission of harmful exhaust gases and in terms of increasing economy and efficiency. Influential parameters on the economy of the system's application were identified (change in fuel price, device cost price, change in regulations on permitted emissions of harmful exhaust gases...) and sensitivity analysis to changes in these input parameters was performed. When defining and analyzing the solid oxide fuel cell system, a system was dimensioned that would replace three existing turbogenerators with a total nominal power of 11100 kW. Based on the obtained results of the conducted research, it was concluded under which operating conditions the new hybrid system increases efficiency by 12 % and reduces exhaust gas emissions between 72.56 % and 81.64 % depending on the discharge flow of compressed natural gas.
