The following description and the accompanying drawings are presented for the overall understanding of the present invention, and thus the technical scope of the present invention is not limited thereto, and detailed descriptions of well-known structures and functions that may unnecessarily obscure the subject matter of the present invention are provided. It will be omitted.

도 1은 본 발명의 실시예에 따른 유기랭킨사이클을 이용한 선박용 연료 공급 시스템을 나타낸 도이다.1 is a view showing a marine fuel supply system using an organic Rankine cycle according to an embodiment of the present invention.

도 1을 참조하면, 본 발명인 유기랭킨사이클을 이용한 선박용 연료 공급 시스템은 연료공급라인(100), 유기랭킨사이클회로(200), 폐열회수라인(300)을 포함하여 이루어지며, 연료공급라인(100)과 유기랭킨사이클회로(200) 및 폐열회수라인(300)이 상호 열교환하여 액화가스를 기화시켜 연료로 사용하며, 각 라인 및 회로에서 터빈에 의해 발전하여 전기를 생산할 수 있는 것을 주요 요지로 한다.Referring to FIG. 1, the ship fuel supply system using the organic Rankine cycle according to the present invention includes a fuel supply line 100, an organic Rankine cycle circuit 200, a waste heat recovery line 300, and a fuel supply line 100. ) And the organic Rankine cycle circuit 200 and the waste heat recovery line 300 heat exchange with each other to vaporize the liquefied gas to be used as fuel, and the main point is to generate electricity by generating a turbine in each line and circuit. .

상기 연료공급라인(100)은 액화가스를 엔진(120,130)에 공급하는 라인이다.The fuel supply line 100 is a line for supplying liquefied gas to the engines 120 and 130.

상기 연료공급라인(100)은 저장탱크에 저장된 액화가스를 액화가스 펌프(110)의 펌핑에 의해 사용하는 엔진(120,130)으로 공급되게 하는 것으로, 상기 저장탱크와 상기 엔진(120,130) 사이에는 액화가스 기화기(140)가 설치되어 상기 액화가스를 기화시켜 상기 엔진(120,130)에 공급되게 할 수 있다. The fuel supply line 100 is to supply the liquefied gas stored in the storage tank to the engine 120,130 to be used by the pumping of the liquefied gas pump 110, the liquefied gas between the storage tank and the engine (120,130) A vaporizer 140 may be installed to vaporize the liquefied gas so as to be supplied to the engines 120 and 130.

그리고, 기화된 액화가스를 엔진(120,130)으로 바로 공급하기 전에 상기 액화가스 기화기(140)와 상기 엔진(120,130) 사이에 설치된 액화가스 터빈(150)으로 유입되게 하여 전기를 생산할 수 있다.In addition, before supplying the vaporized liquefied gas directly to the engines 120 and 130, electricity may be generated by flowing into the liquefied gas turbine 150 installed between the liquefied gas vaporizer 140 and the engines 120 and 130.

상기 액화가스는 -161℃에서 액화가스 기화기(140)에 의해 약 -5℃가 되게 되며, 상기 액화가스 기화기(140)의 열원이 부족한 경우에는 상기 액화가스 기화기(140)와 액화가스 터빈(150) 사이에 설치된 액화가스 히터(160)를 통해 액화가스에 열원을 별도로 공급하여 약 50℃까지 상승시킬 수 있다. 열원은 엔진의 냉각수를 순환시키는 재킷워터(170,180)의 열원이며, 재킷워터(170,180)는 글리콜워터 히터(191)를 통해 글리콜워터(190)를 가열되게 하며, 가열된 글리콜워터(190)는 상기 액화가스 히터(160)에 열원을 공급하게 하여 액화가스를 기화시킬 수 있게 되며, 기화된 액화가스는 상기 액화가스 터빈(150)에 공급되어 발전할 수 있다.The liquefied gas is about -5 ℃ by the liquefied gas vaporizer 140 at -161 ℃, when the heat source of the liquefied gas vaporizer 140 is insufficient, the liquefied gas vaporizer 140 and the liquefied gas turbine 150 The heat source may be separately supplied to the liquefied gas through the liquefied gas heater 160 installed between the upper and lower portions to about 50 ° C. The heat source is a heat source of the jacket water (170, 180) for circulating the coolant of the engine, the jacket water (170, 180) to heat the glycol water 190 through the glycol water heater 191, the heated glycol water 190 is The liquefied gas may be vaporized by supplying a heat source to the liquefied gas heater 160, and the liquefied gas may be supplied to the liquefied gas turbine 150 to generate electricity.

앞서 상기 액화가스 기화기(140)의 열원은 폐열회수라인(300)의 폐열가스 열원을 이용하게 된다. 이때 엔진이 가동하지 않는 경우에는 폐열가스의 열원이 없어 액화가스 기화기(140)에 열원을 충분히 제공하지 못하므로 별도의 액화가스 히터(160)가 필요하게 된다.The heat source of the liquefied gas vaporizer 140 uses the waste heat gas heat source of the waste heat recovery line 300. In this case, when the engine does not operate, since there is no heat source of waste heat gas, the liquefied gas vaporizer 140 does not provide a sufficient heat source, so a separate liquefied gas heater 160 is required.

상기 유기랭킨사이클회로(200)는 액화가스에 기화에 필요한 열을 공급하는 회로이다.The organic Rankine cycle circuit 200 is a circuit for supplying heat required for vaporization to the liquefied gas.

상기 유기랭킨사이클회로(200)는 열매체를 유기랭킨 펌프(210), 유기랭킨 기화기(220), 유기랭킨 터빈(230), 상기 액화가스 기화기(140) 및 유기랭킨 응축기(240)기로 순환시키게 되어 상기 액화가스 기화기(140)에 열원을 공급할 수 있게 된다. The organic Rankine cycle circuit 200 is to circulate the heat medium to the organic Rankine pump 210, organic Rankine vaporizer 220, organic Rankine turbine 230, the liquefied gas vaporizer 140 and organic Rankine condenser 240 The heat source can be supplied to the liquefied gas vaporizer 140.

또한, 상기 유기랭킨 터빈(230)이 설치됨으로써 전기를 생산할 수 있는 이점도 있다. 여기서 유기랭킨 터빈(230)에 순환되는 열매체는 폐열회수라인(300)의 폐열가스 온도 170℃와 열교환에 의해 약 160℃ 까지 상승되어 발전할 수 있으며, 발전 후 유기랭킨 터빈(230)에서 배출되는 열매체는 약 21℃ 온도로 상기 액화가스 기화기(140)에 공급되므로 기화에 필요한 충분한 열원을 제공할 수 있다.In addition, by installing the organic Rankine turbine 230 there is an advantage that can produce electricity. Here, the heat medium circulated in the organic Rankine turbine 230 may be generated by being heated up to about 160 ° C. by heat exchange with the waste heat gas temperature 170 ° C. of the waste heat recovery line 300, and discharged from the organic Rankine turbine 230 after power generation. Since the heat medium is supplied to the liquefied gas vaporizer 140 at a temperature of about 21 ° C., it may provide a sufficient heat source for vaporization.

상기 폐열회수라인(300)은 엔진 폐열가스 열원을 유기랭킨사이클회로(200)에 공급 또는 스팀 터빈(321)으로 공급하여 발전할 수 있게 한다.The waste heat recovery line 300 allows the engine waste heat gas heat source to be supplied to the organic Rankine cycle circuit 200 or to the steam turbine 321 to generate electricity.

상기 폐열회수라인(300)은 상기 엔진에서 배출되는 약 170℃ 고온의 폐열가스를 이코노마이저에 회수하고, 상기 폐열가스를 상기 유기랭킨 기화기(220)에 열원을 공급되게 하는 제1라인(310)과, 상기 제1라인(310)에서 분기되고 상기 폐열가스에 의해 발전되게 하는 스팀 터빈(321)이 설치되는 제2라인(320)이 포함된다.The waste heat recovery line 300 recovers the waste heat gas having a high temperature of about 170 ° C. discharged from the engine to an economizer, and supplies the heat source to the organic Rankine vaporizer 220.
