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 requiring fuel methane value control, including an integrated fuel supply heater (Combined LNG to Gas Heater) and an integrated fuel integrating a low temperature heater, a medium carbon remover, and a high temperature heater in one unit. SUMMARY A fuel supply system and method comprising a feed heater is provided. The liquefied gas fuel supply heater of a marine engine that requires a methane number adjustment according to the present invention, the liquefied gas supply unit for receiving a liquefied gas; A vaporization unit for vaporizing at least a portion of the supplied liquefied gas; A heating unit for heating the gas vaporized in the vaporization unit; And a gas discharge part for discharging the gas heated by the heating part, the tray filtering out impurities in the fluid vaporized in the vaporization part and moving to the heating part. And a drain part for discharging the liquid not vaporized from the vaporization part.
