LNG FUEL SUPPLY SYSTEM FOR LOW PRESSURE DUAL FUEL ENGINE

摘要

PURPOSE: A liquefied natural gas (LNG) fuel supplying system for a low-pressure dual fuel engine is provided to remove heavier hydrocarbon components, and to efficiently simplify overall system configuration. CONSTITUTION: An LNG fuel supplying system for a low-pressure dual fuel engine includes a fuel tank (100), a fuel delivering means (220), a low-temperature heat exchanger (300), a fuel supply means (400), and a discharge line (500). The fuel tank stores the high-pressure LNG. A fuel delivering means guides the LNG in the fuel tank to the outside. The low-temperature heat exchanger stores and heats the transferred LNG at the same time and divides the LNG into gas and liquid. The fuel supply means supplies the gas vaporized from the low-temperature heat exchanger to the low-pressure dual fuel engine. The discharge line is installed on the lower portion of the low-temperature heat exchanger.
