SYSTEM FOR SUPPLYING FUEL GAS FOR MEGI ENGINE AND METHOD THEREOF

摘要

PURPOSE: A system and a method for supplying fuel gas for a MEGI engine are provided to always maintain the temperature of fuel gas regardless of a sudden temperature change. CONSTITUTION: A system(100) for supplying fuel gas for a MEGI engine comprises a supply line(110), a high pressure pump(120), a vaporizer(130), a pressure control valve(140), and a unit for maintaining pressure. The supply line supplies LNG from a storage tank to the MEGI engine. The high pressure pump is installed to supply LNG with compressing the LNG. The vaporizer is installed in the supply line to vaporize the compressed LNG. The pressure control valve is installed at the rear part of the vaporizer in the supply line. The unit for maintaining pressure constantly maintains pressure differences between front and rear parts of the pressure control valve.
