CONTRIBUTION TO THE THERMAL CALCULATION OF SHIP PROPULSION STEAM GENERATORS FOR LNG TANKER SHIPS

Efficiencies of the steam circuit and boiler. The steam propulsion as the LNG boil-off can be completely combusted at sea as well as in a harbor. The fuel consumption of a ship propulsion steam system is directly dependent on the efficiencies of the steam circuit and boiler. The steam generator burns either pure fuel oil or a mixture of fuel oil and boil-off. The influences of the natural gas composition which differs according to the deposit and of the nitrogen content which varies during the ship's voyage, as well as the consequences of the boil-off/heating fuel oil ratio for power, efficiency, flue gas temperature, and superheated steam temperature characteristic of the steam generator are investigated.
