Abstract

The present invention relates to a cold heat recovery apparatus using an LNG fuel which recovers cold heat from the LNG fuel when an evaporated gas from a liquefied gas is re-liquefied as cargo to reduce costs required for installing and operating a re-liquefying apparatus and reduce energy consumption and environmental pollution materials without consuming additional energy in a re-liquefying process, and to a liquefied gas carrier including the same. According to the present invention, the cold heat recovery apparatus, which uses cold heat from an LNG fuel to treat the evaporated gas generated in a liquefied gas tank, includes a cold heat usage unit that uses the cold heat from an LNG, which is supplied as fuel from the LNG fuel tank, which stores LNG, to an engine, to treat the evaporated gas generated in the liquefied gas tank.

Description

technical field [0001] The present invention relates to a cold and heat recovery device using liquefied natural gas (LNG) fuel and a liquefied gas carrier including the device, and more particularly, to a cold and heat recovery device and a liquefied gas carrier using LNG fuel, wherein The cost involved in the installation and operation of the reliquefaction facility can be reduced by recovering and utilizing the cold heat of the LNG fuel when the boil-off gas of the liquefied gas as cargo is reliquefied, and because no additional energy is consumed during the reliquefaction process , so energy saving and reduction of environmental pollutants can be realized. Background technique [0002] Recently, there has been an increasing need to reduce SO generated during voyages of ships X , NO X and CO 2 . Due to such environmental problems and higher oil prices, the use of clean fuel LNG as a propellant fuel has been proposed and developed to replace oils such as heavy oil or di...
