VAPORIZED GAS FUEL SUPPLY SYSTEM AND VAPORIZED GAS TEMPERATURE CONTROL METHOD THEREOF

摘要

The present invention relates to a vaporized gas fuel supply system, which vaporizes liquefied natural gas (LNG) to be supplied to an engine as fuel, and to a vaporized gas temperature control method thereof. The vaporized gas fuel supply system comprises: a heat source supply line for supplying heated glycol water to a first and a second heat exchanger; a first heat exchanger for vaporizing LNG by applying heat to the same, and supplying the vaporized LNG to a first engine as fuel; and a second heat exchanger for vaporizing LNG by applying heat to the same by the heated glycol water, and supplying the vaporized LNG to a second engine as fuel.
