Abstract
U ovom radu opisan je amonijak kao obična tvar te kao potencijalno buduće gorivo. Objašnjeni su razlozi njegove upotrebe u kontekstu pozitivnog utjecaja na okoliš te dekarbonizacije brodskog transporta. Opisani su načini skladištenja amonijaka i njegova dobivanja Haber-Boschovim postupkom. Prikazana je usporedba amonijaka s drugim gorivim te su navedene prednosti i nedostaci njegove upotrebe. Istraženi su načini njegova izgaranja, potencijalna poboljšanja i povećanja brzine izgaranja smjese amonijaka i zraka. Prikazana je njegova upotreba u gorivnim ćelijama te u MAN-ovom dvotaktnom motoru. Shematski je prikazan sustav goriva, a također je i proračunat sustav goriva prekooceanskog broda s pogonskim sustavom snage 10MW pri čemu je određen volumen dnevnog tanka, spremnika goriva, dimenzioniran je cjevovod te pumpa goriva i prikazana je ekonomska iskoristivost plovidbe broda na amonijak.
Abstract (english)
This master's thesis describes ammonia as a common substance and as a potential future fuel. The reasons for its use in context of a positive impact on the environment and the decarbonization of ship transport are explained. Methods of ammonia storage and its production by the Haber-Bosch process are described in this thesis. A comparison of ammonia with other fuels is presented and the advantages and disadvantages of its use are stated. Ways of its combustion, potential improvements and increases in the combustion speed of the mixture of ammonia and air were investigated. Its use in fuel cells and in MAN's two stroke engine is shown. The fuel system is shown schematically and the fuel system of an ocean-going ship with a 10MW propulsion system is also calculated where the volume of the day tank is determined, fuel tank is determined, the pipeline and the fuel pump are dimensioned and the economic usability of the ship's navigation on ammonia is shown.
