FUEL GAS SUPPLY SYSTEM FOR LNG CARRIER USING DUEL FUEL DIESEL ELECTRIC PROPULSION ENGINE

摘要

PURPOSE: A fuel feeding system for a liquefied natural gas ship using a different kind fuel diesel engine screw pipe with an increased methane value is provided to prevent the non-ideal explosion phenomenon of a different kind fuel diesel engine by mixing the fuel gas with nitrogen and carbon dioxide. CONSTITUTION: A force evaporation natural gas droplet separator(9) is connected to an outlet of a high-pressure compressor. A nitrogen or dioxide carbon supply pipe(40) is connected to the gas outlet line of the force evaporation natural gas droplet separator. The nitrogen or dioxide carbon supply pipe includes a nitrogen flow control valve(28) and a carbon dioxide flow control valve(29).
