Description
본 발명은 전기 추진 시스템을 사용하는 LNG선에서 저장탱크의 압력을 적절한 수준으로 유지하기 위해 증발가스(BOG, Boil-off gas)를 처리하는 증발가스 처리에 관한 것으로서, 보다 상세하게는 저장탱크에서 발생된 증발가스를 이중연료 엔진과 가스터빈 발전기를 이용하여 전기로 변환시킨 후에 로드 뱅크에서 열로 변환시켜 외부로 방출하는 전기 추진 시스템을 사용하는 엘엔지 선에서의 증발가스 처리장치 및 방법에 관한 것이다.The present invention relates to the treatment of boil-off gas (BOG, Boil-off gas) in order to maintain the pressure of the storage tank at an appropriate level in the LNG carrier using an electric propulsion system, more specifically in the storage tank The present invention relates to an apparatus and a method for treating boil-off gas at an LNG vessel using an electric propulsion system that converts generated boil-off gas into electricity using a dual fuel engine and a gas turbine generator, and then converts it into heat in a load bank and releases it to the outside.
일반적으로, 내연기관 추진 시스템을 사용하는 LNG선에서는 저장탱크 내부에서 자연적으로 기화되어 발생되는 증발가스를 메인 보일러에서 증발가스를 연소시켜 수증기를 발생시키고, 발생된 수증기를 이용하여 증기터빈(Steam Turbine)을 구동시키므로써 선박의 운용에 필요한 동력을 획득하는 구조로 이루어져 있다.In general, in LNG carriers using an internal combustion engine propulsion system, the boil-off gas, which is naturally vaporized in the storage tank, is burned by burning the boil-off gas in the main boiler, and steam is generated by using the generated steam. It is structured to acquire the power necessary for the operation of the ship by driving).
도 1은 일반적인 내연기관 추진 시스템을 사용하는 LNG 선에서의 증발가스 처리장치를 도시하는 도면으로서, 상기 도면에 도시하였듯이, LNG 선상에 설치된 저장탱크(1)에서 적재되어 있는 액화 천연가스가 자연 기화되어 발생되는 증발가스는 저밀도 압축기(2)를 통해 보일러(3)로 이송되고, 상기 보일러(3)에서는 증발가스를 연소시키면서 발생되는 연소열을 이용하여 냉각수를 증기 상태로 기화시킨다.1 is a view showing an apparatus for treating boil-off gas in an LNG carrier using a general internal combustion engine propulsion system, and as shown in the drawing, liquefied natural gas loaded in a storage tank 1 installed on a LNG vessel is naturally vaporized. The generated evaporated gas is transferred to the boiler 3 through the low density compressor 2, and the boiler 3 vaporizes the cooling water to a vapor state by using combustion heat generated while burning the evaporated gas.
상기 보일러(3)에서 생성된 고온의 증기는 증기 배관을 통해 증기 터빈(4)으로 공급되어 선반 운용에 필요한 동력을 발생시키고, 상기 증기 터빈(4)을 통과한 저온의 증기는 응축기(5)로 이송되어 저온의 액체 상태로 상변화된다.The high temperature steam generated by the boiler 3 is supplied to the steam turbine 4 through a steam pipe to generate power for shelf operation, and the low temperature steam passed through the steam turbine 4 is condenser 5. It is transferred to the low temperature liquid phase.
상기 응축기(5)를 통과하면서 액체 상태로 상변화된 응축수는 배관을 통해 펌프(6)로 이송되고, 상기 펌프(6)에서 가압된 응축수는 보일러(3)로 재공급되어 증발가스의 연소열에 의해 재기화된다.The condensed water phase-changed into a liquid state while passing through the condenser 5 is transferred to the pump 6 through a pipe, and the condensed water pressurized by the pump 6 is supplied to the boiler 3 again by the heat of combustion of the boil-off gas. Is regasified.
그러나, 선박의 계류 또는 정박중에 저장탱크(1)에서 발생되는 증발가스는 증기터빈(4)을 통해 동력화 시킬 필요가 없으므로 보일러(3)에서 연소시킨 후 연소열에 의해 기화된 고온의 증기를 메인 덤프 시스템(7)으로 이송시키는데, 상기 메인 덤프 시스템(7)에서는 증기의 온도를 감소시킨 후에 응축기(5)로 공급하게 된다.However, since the boil-off gas generated in the storage tank 1 during the mooring or berthing of the ship does not need to be energized through the steam turbine 4, the main dump of the high-temperature steam vaporized by the combustion heat after combustion in the boiler 3 The main dump system (7) is fed to the condenser (5) after reducing the temperature of the steam.
상기 메인 덤프 시스템(7)은 응축기(5)의 응축 부하를 감소시키기 위한 시스템으로서, 배관을 통해 이송되는 증기에 직접 냉각수를 분사하여 증기의 온도를 감소시키는 구조이다.The main dump system (7) is a system for reducing the condensation load of the condenser (5), the structure to reduce the temperature of the steam by spraying the coolant directly to the steam transported through the pipe.
상기 응축기(5)를 통과하면서 액체 상태로 상변화된 응축수는 펌프(6)로 이송되고, 상기 펌프(6)에서 가압되어 보일러(3)로 재공급된다.The condensed water phase-changed into a liquid state while passing through the condenser 5 is transferred to the pump 6, pressurized by the pump 6, and supplied again to the boiler 3.
상기와 같은 구성으로 이루어지는 일반적인 내연기관 추진 시스템을 사용하는 LNG선에서의 증발가스 처리장치는 보일러에서 증발가스를 연소시키고, 상기 증발가스 연소열에 의해 생성되는 증기를 증기터빈과 메인 덤프 시스템에서 처리하는 구조로 형성된다.An apparatus for treating boil-off gas in an LNG carrier using a general internal combustion engine propulsion system having the above configuration may burn boil-off gas in a boiler and process steam generated by the heat of combustion of the boil-off gas in a steam turbine and a main dump system. It is formed into a structure.
그러나, LNG 선에 전기 추진 시스템을 적용할 경우 추진용으로 사용하는 보일러가 삭제되므로 새로운 증발가스 처리장치가 요구된다.However, when the electric propulsion system is applied to LNG carriers, the boiler used for propulsion is deleted, so a new boil-off gas treatment apparatus is required.
상술한 증발가스 처리장치 및 방법을 전기 추진 시스템을 사용하는 LNG선에 적용시킨 본 발명의 목적은 저장탱크에서 발생되는 증발가스를 가스터빈 발전기와 이중 연료엔진을 이용하여 전기로 변환시키고 이 전기를 로드 뱅크로 송전하여 열로 전환시킴으로써 저장탱크의 압력을 적절한 수준으로 유지하여 보호 하고자 하는데 있다.The object of the present invention is to apply the above-described boil-off gas treatment apparatus and method to an LNG carrier using an electric propulsion system, and convert the boil-off gas generated from the storage tank into electricity using a gas turbine generator and a dual fuel engine and convert the electricity.
