Specification of Gas Fuels for Ship Engines

Zabrinutost za okoliš i polagano smanjivanje zaliha nafte natjeralo je istraživače na pronalaženje alternative standardnim gorivima. Pretjerana uporaba fosilnih goriva dovela je do smanjenja zaliha te do povećanog zagađivanja okoliša. Jedno od rješenja jest uporaba plinovitih goriva tj. LPG-a i LNG-a. Uporaba tih goriva je obećavajući pristup ka smanjenoj ovisnosti o standardnim fosilnim gorivima te smanjenoj emisiji ugljičnog dioksida te ostalih zagađivača. Kvaliteta plinovitih goriva od velike je važnosti za performanse i vijek trajanja motora. Brodovi za prijevoz naftnih i zemnih plinova nazivamo LPG i LNG „carriers-ima“. Propulzijski strojevi brodova koji koriste plinovita goriva kao pogonska, mogu biti turbine (parna i plinska) te motori s dvojnim sustavom goriva.Concerns for the environment and depletion of crude oil made researchers look for alternative to standard fuels. Overuse of fossil fuels resulted in reduced reserves of the same, and an increase in environment pollution. One of the solutions for the problems is in use of gas fuels, i.e. LPG and LNG. Use of those fuels is a promising approach towards reduced dependence to standard fuels and lowered emission of carbon dioxide and other pollutants. Fuel quality is of great importance for performance and lifetime of the engine. Ships used to transfer LNG and LPG are called LNG and LPG carriers. Ship propulsion systems that work on gas fuels can be turbines (steam and gas) and engines with dual fuel system also known as dual-fuel engines
