Description

연료공급시스템{FUEL GAS SUPPLY SYSETM}FUEL GAS SUPPLY SYSETM

본 발명은 연료공급시스템에 관한 것이다.The present invention relates to a fuel supply system.

온실가스 및 각종 대기오염 물질의 배출에 대한 국제해사기구(IMO)의 규제가 강화됨에 따라 조선 및 해운업계에서는 기존 연료인 중유, 디젤유의 이용을 대신하여, 청정 에너지원인 천연가스를 선박의 연료가스로 이용하는 경우가 많아지고 있다.As IMO regulations on the emission of greenhouse gases and various air pollutants are strengthened, shipbuilding and marine industries are replacing the use of heavy fuel oil and diesel oil, In many cases.

연료가스 중에서 널리 이용되고 있는 천연가스(Natural Gas)는 메탄(Methane)을 주성분으로 하며, 통상적으로 그 부피를 1/600로 줄인 액화가스(Liquefied Gas) 상태로 변화되어 저장 및 운반되고 있다.Natural gas, which is widely used in fuel gas, is mainly stored as methane and is stored and transported in a liquefied gas state where the volume thereof is reduced to 1/600.

액화가스를 운반하는 선박은 액화가스를 저장할 수 있도록 단열 처리된 저장탱크를 구비한다. 또, 이러한 선박은 저장탱크에서 자연적으로 발생하는 증발가스(Boiled Off Gas) 또는 저장탱크의 액화가스를 기화시켜 엔진의 연료로 공급하는 연료공급시스템을 마련할 수 있다. 선박의 엔진에는 DFDE(Dual Fuel Disel Electric) 엔진 등과 같은 저압(약 5~8bar)의 분사엔진, ME-GI 엔진(Man B&W 사의 Gas Injection 엔진)과 같은 고압(약 150~700bar)의 분사엔진 및 X-DF 엔진과 같은 중압(약 16~18bar)의 연료가스로 연소가 가능한 중압가스 분사엔진이 이용될 수 있다.The ship carrying the liquefied gas has a storage tank which is insulated to store the liquefied gas. In addition, such a vessel can provide a fuel supply system that vaporizes boiled off gas naturally occurring in the storage tank or liquefied gas in the storage tank to supply fuel to the engine. The engine of the ship is equipped with a low-pressure (about 5-8 bar) injection engine such as a DFDE (Dual Fuel Disel Electric) engine, a high-pressure (about 150-700 bar) injection engine such as the ME-GI engine (Man B & W's Gas Injection engine) A medium pressure gas injection engine capable of combusting with medium pressure (about 16-18 bar) fuel gas such as an X-DF engine can be used.

상술한 연료공급시스템은 저장탱크로부터 공급된 증발가스를 압축부에 의해 압축시켜 엔진의 연료로 공급한다.The fuel supply system described above compresses the evaporated gas supplied from the storage tank by the compression section and supplies it to the fuel of the engine.

그러나, 이러한 압축부는 에너지 소비가 높아 시간이 지날수록 가동효율이 떨어지는 문제점이 있다. However, such a compression unit has a problem in that the energy efficiency is low as the energy consumption is high over time.

상술한 저장탱크(102)는 단열상태를 유지하면서 연료를 액화상태로 저장하는 멤브레인형 탱크, SPB형 탱크, 타입 C 탱크 등을 포함할 수 있다. 저장탱크(102)에 저장된 액화가스는 액화상태로 저장할 수 있는 LNG(Liquefied Natural Gas), LPG(Liquefied Petroleum Gas), DME(Dimethylether), 에탄(Ethane) 중 어느 하나일 수 있으나 이에 한정되는 것은 아니다. The above-described storage tank 102 may include a membrane type tank, a SPB type tank, a type C tank, or the like, which stores the fuel in a liquefied state while maintaining an adiabatic state. The liquefied gas stored in the storage tank 102 may be any one of Liquefied Natural Gas (LNG), Liquefied Petroleum Gas (LPG), Dimethylether (DME), and Ethane, which is stored in a liquefied state, but is not limited thereto .

저장탱크(102) 내부압력은 저장된 액화가스가 LNG일 경우 대략 1bar로 유지되거나 연료공급조건을 고려해 그보다 높은 압력으로 유지될 수 있다. 저장탱크(102) 내부온도는 LNG의 액화상태 유지를 위해 대략 ―163℃도 정도로 유지될 수 있다. The pressure inside the storage tank 102 may be maintained at about 1 bar when the stored liquefied gas is LNG or at a higher pressure than that given the fuel supply conditions. The internal temperature of the storage tank 102 may be maintained at about -163 < 0 > C to maintain the liquefied state of the LNG.
