Marine gas turbines

Brodske plinske turbine predstavljaju toplinske strojeve s unutrašnjim izgaranjem u kojima se kemijska energija vrućih plinova dobivena od komore izgaranja pretvara u mehanički rad pogonske turbine. Glavni poticaj u razvoju plinskih turbina za pogon broda očituje se u njihovoj maloj težini, malim dimenzijama,velikim snagama i velikom ubrzanju kojim se uvelike poboljšavaju manevarske sposobnosti broda. U radu su osim sustava regulacije i osnovnih elemenata prikazani i objašnjeni sustavi goriva i ulja za podmazivanje te je ukazano na važnost održavanja cjelokupnog sustava.Marine gas turbines represent thermal machines with internal combustion in which the chemical energy of the hot gases, produced by the combustion chamber, is converted into mechanical work of turbine. The main impulse in the development of gas turbines for ship propulsion is reflected in their low weight, small size, high power and rapid acceleration that greatly improves maneuverability of the ship. Except regulation system and basic elements, this paper is presenting and explaining fuel and lubricating oil system and indicate the importance of maintaining the overall system
