The present invention relates to a device to vaporize liquefied natural gas stored in a storage tank (1), comprising: a mixer (10) to mix liquefied natural gas and evaporative gas supplied from the storage tank (1); a high-pressure pump (20) to compress the liquefied natural gas having a temperature raised in the mixer (10); a first heat exchanger (30) to receive the liquefied natural gas which has been compressed at high pressure by the high-pressure pump (20), and vaporizing the liquefied natural gas by primarily heating the liquefied natural gas; a second heat exchanger (40) to secondarily heat the natural gas vaporized by being primarily heated in the first heat exchanger (30); a third heat exchanger (50) to thirdly heat and transmit the natural gas heated secondarily in the second heat exchanger (50); a first pipe (60) to transmit part of the natural gas, transmitted from the first heat exchanger (30) to a condenser (10), by mediating between the first and second heat exchangers (30, 40); and a second pipe (70) to transmit part of the natural gas transmitted from the second heat exchanger (40), to an internal power generator (7) by mediating between the second and third heat exchangers (40, 50).
본 발명은, 저장탱크(1)에 저장된 액화천연가스를 기화시키는 장치로서, 저장탱크(1)에서 공급되는 액화천연가스 및 증발가스가 혼합되는 혼합기(10)와; 혼합기(10)에서 승온된 액화천연가스를 압축하는 고압펌프(20)와; 고압펌프(20)에 의해 고압으로 압축된 액화천연가스를 공급받아 1차 가열하여 기화시키는 제1열교환기(30)와; 제1열교환기(30)에서 1차 가열되어 기화된 천연가스를 2차 가열하는 제2열교환기(40)와; 제2열교환기(50)에서 2차 가열된 천연가스를 3차 가열하여 송출하는 제3열교환기(50)와; 제1, 2열교환기(30, 40) 사이에 매개되어 제1열교환기(30)에서 송출되는 천연가스 중의 일부를 응축기(10)로 송출하는 제1배관(60)과; 제2, 3열교환기(40, 50) 사이에 매개되어 제2열교환기(40)에서 송출되는 천연가스 중의 일부를 내부발전기(7)로 송출하는 제2배관(70)을; 포함하여 이루어지는 액화천연가스의 기화장치를 제공한다.
