Description

스팀터빈의 복수기 폐열을 재활용하는 부유식 발전선{OPERATING ENERGY SAVING FLOATING LNG RE-GASIFICATION POWER PLANT}[0001] OPERATING ENERGY SAVING FLOATING LNG RE-GASIFICATION POWER PLANT [0002]

본 발명은 부유식 발전선에 관한 것으로, 보다 상세하게는 스팀터빈의 스팀을 회수하기 위한 복수기에서 발생하는 폐열을 재활용함으로써 운전 에너지를 절감한 부유식 발전선에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a floating power generation line, and more particularly, to a floating power generation line that reduces operating energy by recycling waste heat generated in a condenser for recovering steam of a steam turbine.

액화천연가스(LNG)를 연료로 사용하는 발전 설비는 주로 육상에 설치되는데, 이를 위해선 부지를 매입해야 하고, 송전선 등을 설치해야 하므로 과도한 설치비용이 발생하였다.Power generation facilities using liquefied natural gas (LNG) as a fuel are mainly installed on the land. In order to do this, land must be purchased and transmission lines must be installed, resulting in excessive installation costs.

이에 따라, 최근에는 원료 수급이 용이하고 용지확보 비용이 저렴한 해안가에 발전 설비를 설치하는 사례가 늘어나고 있다.Accordingly, in recent years, there has been an increasing number of cases in which power generation facilities are installed on coastal areas where raw material supply and demand is easy and the cost of securing paper is low.

하지만, 해안가에 설치되는 발전 설비의 경우, 화재의 원인이 되는 누전, 합선 등을 야기하여 안정상의 문제가 발생할 수 있었다. 특히, 파력(wave)에 의한 유동과 진동에 의해 2차적인 피해가 발생할 우려도 있었다.However, in the case of the power generation facilities installed on the shore, a short-circuit or a short-circuit which causes a fire may cause stability problems. Particularly, there was a possibility of secondary damage due to flow and vibration caused by waves.

It should be noted that the embodiments described in the present specification and the configurations shown in the drawings are only the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention, It should be understood that various equivalents and modifications are possible.

도 1은 부유식 발전선의 개략적인 구조를 나타낸 구성도이다.1 is a schematic view showing a schematic structure of a floating power generation line.

도시된 바와 같이, 부유식 발전선(100)은 선체(100)와, 선체에 형성되며 LNG가 저장되는 LNG 저장탱크(120)와, 상기 LNG 저장탱크(120)로부터 공급되는 LNG를 기화시키는 기화부(130)와, 상기 기화부(130)에 의해 기화되는 천연가스를 연료로 사용하여 동력을 생산하는 가스터빈(140)과, 상기 가스터빈(140)으로부터 발생하는 배기가스의 폐열을 이용하여 스팀을 발생시키는 폐열회수보일러(150)와, 상기 폐열회수보일러(150)에서 발생되는 스팀에 의하여 동력을 생산하는 스팀터빈(160)과, 상기 가스터빈(140) 및 스팀터빈(160)의 동력에 의하여 전력을 생산하는 발전기(170)와, 상기 스팀터빈(160)에서 배출되는 스팀을 냉각시켜 상기 폐열회수보일러(150)로 순환시키는 복수기(180)를 포함한다.As shown in the figure, the floating power generation line 100 includes a hull 100, an LNG storage tank 120 formed in the hull and storing the LNG, a vaporization unit 120 for vaporizing the LNG supplied from the LNG storage tank 120, A gas turbine 140 for generating power using natural gas vaporized by the gasification unit 130 as fuel and waste heat of the exhaust gas generated from the gas turbine 140, A waste heat recovery boiler 150 for generating steam and a steam turbine 160 for generating power by steam generated from the waste heat recovery boiler 150 and a steam generator 160 for generating power from the gas turbine 140 and the steam turbine 160 And a condenser 180 for circulating the steam discharged from the steam turbine 160 to the waste heat recovery boiler 150 by cooling the steam discharged from the steam turbine 160.

복수기(180)는 해수를 유입하여 유입된 해수를 이용하여 증기수를 회수하는 역할을 수행하는 것으로, 복수기(180)에서 배출되는 해수는 약 40~50℃의 고온이다. 종래에는 복수기(180)에서 배출되는 해수를 그대로 바다로 방류하고 있었는데, 이러한 고온 해수의 방출은 부유식 발전선 주변 해수의 온도를 상승시켜 해양 생태계에 좋지 않은 영향을 미칠수도 있다.The condenser 180 serves to recover the steam water by using the seawater introduced into the condenser 180. The seawater discharged from the condenser 180 has a high temperature of about 40 to 50 ° C. Conventionally, seawater discharged from the condenser 180 is discharged to the sea as it is. However, the release of such high temperature seawater may raise the temperature of the seawater around the floating power generation line, which may adversely affect the marine ecosystem.

또한, 부유식 발전선에는 상술한 설비들 이외에도 선원들을 위한 편의설비, 추진설비, 담수를 발생시키기 위한 조수기 등이 구비되며, 이러한 설비등 중에서는 별도의 보일러나 가열장치 등을 이용하여 열을 공급하고 있는 설비도 다수 존재한다.In addition to the above-mentioned facilities, the float-type power generation line is equipped with convenience facilities for crew members, propulsion facilities, and an aquarium for generating fresh water. Among these facilities, a boiler or a heating device is used to heat There are many facilities that supply.

본 발명은 복수기(180)에서 배출되는 고온의 해수를 이용하여, 가열이 필요한 설비등에서 활용될 수 있도록 함으로써, 부유식 발전선의 에너지 이용 효율을 향상시키기 위한 것이다.
The present invention is intended to improve the energy utilization efficiency of the floating power generation line by allowing high-temperature seawater discharged from the condenser (180) to be utilized in facilities requiring heating.

도 2는 본 발명의 제1실시예에 따른 부유식 발전선의 복수기 해수 유입배출 흐름을 나타낸 블럭도이다.2 is a block diagram showing a seawater inflow and discharge flow of a floating power generation line according to the first embodiment of the present invention.

제1실시예는 복수기(180)에서 배출되는 고온의 해수를 엔진예열장치(210)의 열원으로 사용하는 구조를 나타낸 것이다.The first embodiment shows a structure in which high temperature seawater discharged from the condenser 180 is used as a heat source of the engine preheater 210.

부유식 발전선에는 선박의 추진을 위한 엔진, 발전기의 구동을 위한 엔진이 구비되는데, 이러한 엔진은 시동초기에 예열이 필요하다. 따라서 엔진의 예열을 위한 별도의 엔진예열장치(210)를 구비하는데, 복수기(180)에서 배출되는 고온의 해수를 엔진예열장치(210)로 공급하여, 가열매체로 사용할 수 있다.
The floating power generation line is equipped with an engine for propulsion of the ship and an engine for driving the generator. Such an engine needs preheating at the initial stage of starting. Therefore, a separate engine preheater 210 for preheating the engine is provided. The high temperature seawater discharged from the condenser 180 can be supplied to the engine preheater 210 and used as a heating medium.

도 3은 본 발명의 제2실시예에 따른 부유식 발전선의 복수기 해수 유입배출 흐름을 나타낸 블럭도이다.3 is a block diagram showing a seawater inflow and discharge flow of a floating power generation line according to a second embodiment of the present invention.

제2실시예는 복수기(180)에서 배출되는 고온의 해수를 온수공급장치(220)의 가열매체로 사용하는 경우를 나타낸 것이다. 부유식 발전선에는 선실의 선원의 편의를 위한 온수공급장치(220)가 구비되는데, 온수공급장치(220)는 청수를 약 70~80℃로 가열하여 공급한다. 복수기(180)에서 배출되는 고온의 해수는 50~60℃의 온도를 가지므로, 상기 고온의 해수를 이용하여 온수공급장치(220)로 공급되는 청수의 온도를 예열한 후, 추가 가열장치를 이용하여 청수를 요구온도까지 승온하는 구조를 제공함으로써, 온수공급장치(220)에서 소모되는 에너지를 절감할 수 있다.
The second embodiment shows a case where high temperature seawater discharged from the condenser 180 is used as a heating medium for the hot water supply device 220. The float power generation line is provided with a hot water supply device 220 for convenience of the crew of the cabin. The hot water supply device 220 heats and supplies fresh water to about 70 to 80 ° C. Since the high temperature seawater discharged from the condenser 180 has a temperature of 50 to 60 ° C, the temperature of the fresh water supplied to the hot water supply device 220 is preheated by using the high temperature seawater, So that the energy consumed in the hot water supply device 220 can be reduced.

도 4는 본 발명의 제3실시예에 따른 부유식 발전선의 복수기 해수 유입배출 흐름을 나타낸 블럭도이다.FIG. 4 is a block diagram showing a seawater inflow / discharge flow of a floating power generation line according to a third embodiment of the present invention.

제3실시예는 복수기(180)에서 배출되는 고온의 해수를 조수기(230)로 공급하는 경우를 나타낸 것이다.The third embodiment shows a case where high temperature seawater discharged from the condenser 180 is supplied to the water generator 230.

조수기(230)는 해수를 가열하여 발생한 증기로부터 청수를 생산하는 장치이다. 복수기(180)에서 배출되는 고온의 해수를 이용하여 상기 조수기(230)로 공급되는 해수를 예열할 수도 있으며, 복수기(180)에서 배출되는 고온의 해수를 상기 조수기(230)로 직접 급수할 수도 있다.
The water generator 230 is a device for producing fresh water from steam generated by heating seawater. The high temperature seawater discharged from the condenser 180 may be used to preheat the seawater supplied to the water generator 230 and the high temperature seawater discharged from the condenser 180 may be directly supplied to the water generator 230 It is possible.

도 5는 본 발명의 제4실시예에 따른 부유식 발전선의 복수기 해수 유입배출 흐름을 나타낸 블럭도이다.5 is a block diagram illustrating a seawater inflow and discharge flow of a floating power generation line according to a fourth embodiment of the present invention.

제4실시에는 복수기(180)에서 배출되는 고온의 해수가 분배밸브(250)를 거쳐, 엔진예열장치(210), 온수공급장치(220), 조수기(230)로 분배되도록 한 것이다.In the fourth embodiment, the high temperature seawater discharged from the condenser 180 is distributed to the engine preheater 210, the hot water supply device 220, and the water purifier 230 through the distributor valve 250.

이러한 구조는 개별장치의 운전상태에 따라서, 복수기(180)에서 배출되는 고온의 해수의 유량을 조절할 수 있도록 함으로써, 부유식 발전선의 에너지 효율을 더욱 향상시킬 수 있다. 엔진예열장치(210)의 경우 엔진시동시에만 동작되며, 온수공급장치(220)의 경우에도 온수가 사용될 경우에만 추가온수를 생산하게 되며, 조수기(230)의 경우에도 작동상태에서 따라 청수생산유량이 가변하기 때문에, 개별장치의 운전상태에 따라서 고온의 해수의 분배유량을 조절할 수 있도록 한 것이다.
This structure can further improve the energy efficiency of the floating power generation line by allowing the flow rate of the high temperature seawater discharged from the condenser 180 to be adjusted according to the operation state of the individual device. In the case of the engine preheater 210, the hot water supply device 220 is operated only at the same time, and the hot water supply device 220 produces hot water only when hot water is used. In the case of the water purifier 230, The flow rate of the high-temperature seawater can be adjusted according to the operation state of the individual device.
