Fuel Liquefied Gas Supply Heater and Fuel Liquefied Gas Supply System and Method of Engine Required Methane Number Control of Ship

摘要

The present invention relates to a liquefied gas fuel supply system for a marine engine in which the methane level of fuel is required to be controlled, comprising a combined LNG to Gas heater integrated with a low temperature heater, a heavy carbon heater and a high temperature heater, To provide a fuel supply system and method including a supply heater. The liquefied gas fuel supply heater of a marine engine which requires methane control according to the present invention comprises a liquefied gas supply part to which liquefied gas is supplied; A vaporizer for vaporizing at least a part of the supplied liquefied gas; A heating unit for heating the gas vaporized in the vaporizing unit; And a gas discharging portion for discharging the gas heated by the heating portion, wherein the tray filters the impurities in the fluid that is vaporized in the vaporizing portion and moves to the heating portion; And a drain portion for discharging the non-vaporized liquid in the vaporizing portion.
