Fuels and their application on ship with the MAN B&W 12K98MC-C engine example

Kroz ovaj Završni rad obrađuju se pojmovi i vrste brodskih goriva, karakteristike brodskih goriva, odnosno bit će prikazana i objašnjena kemijska svojstva goriva, struktura nafte i naftnih derivata, te kvaliteta paljenja brodskih goriva. Gorivom se treba podrazumijevati samo ona tvar koja omogućuje ekonomično korištenje u njemu vezane topline. Ovaj Završni rad ima za cilj prikazati primjenu goriva na brodu koja se može pronaći na svim današnjim suvremenim brodovima. Bez dobro projektiranog sistema goriva nijedan od sustava unutar samog stroja broda ne može izvršavati svoju funkciju. Za ispravan rad glavnih i pomoćnih brodskih dizelskih motora i plinskih turbina iznimno je važna priprema goriva, tako svaki sustav mora omogućiti dotok čistog goriva prikladne temperature i tlaka do mjesta uporabe. Sustav pripreme goriva obuhvaća ukrcaj goriva, tankove goriva, separaciju goriva, samočistivi filter, regulaciju viskoznosti, ispiranje sustava i uštrcavanje goriva.Throughout this Final paper, the concepts and types of marine fuels, the characteristics of marine fuels, and the chemical properties of fuels, the structure of oil and petroleum products, and the ignition quality of marine fuels will be presented and explained. Only the substance which enables the economical use of the heat bound therein should be considered as fuel. This Final paper aims to show the application of fuel on board that can be found on all modern ships today. Without a well-designed fuel system, none of the systems within the ship's machine itself can perform its function. The proper preparation of the main and auxiliary marine diesel engines and gas turbines is extremely important for the preparation of the fuel, so that each system must allow the supply of clean fuel of the proper temperature and pressure to the point of use. The fuel preparation system includes fuel injection, fuel tanks, fuel separation, self-cleaning filter, viscosity control, system flushing and fuel injection
