선박엔진의 연료공급 시스템{FUEL SUPPLY SYSTEM OF SHIP ENGINE}FUEL SUPPLY SYSTEM OF SHIP ENGINE

본 발명은 선박엔진의 연료공급 시스템에 관한 것으로서, 더욱 상세하게는 엔진의 연료인 MGO(고급연료)와 HFO(저급연료)를 겸용으로 사용도록 함에 있어서, 작업자의 수작업에 의한 연료 전환이 아니라, 엔진 입구의 온도를 감지하고 감지된 엔진온도의 감지값에 의해 자동으로 밸브가 개폐되어 MGO 또는 HFO가 공급되도록 하여 연료 전환에 따른 불편함을 해결할 수 있도록 한 선박엔진의 연료공급 시스템에 관한 것이다.
The present invention relates to a fuel supply system of a ship engine, and more particularly, in order to use MGO (high fuel) and HFO (low fuel), which are engine fuels, not to switch fuel by manual operation of an operator. The present invention relates to a fuel supply system of a ship engine that senses an engine inlet temperature and automatically opens and closes a valve according to a detected value of an engine temperature to supply an MGO or an HFO to solve an inconvenience caused by a fuel change.

일반적으로, 컨테이너 운반선과 같은 상선에는 HFO(Heavy Fuel Oil)와 같은 연료를 사용하는 엔진이 주로 사용된다.In general, engines using fuels such as heavy fuel oil (HFO) are mainly used for merchant ships such as container carriers.

한편, 선박 엔진에 사용되는 연료로는 고급연료인 MGO와 저급연료인 HFO를 겸용하여 사용하고 있으며, 국가에 따라 황이 포함된 HFO의 사용을 규제하는 경우에는 MGO를 사용하여 해상 또는 항구에서 엔진을 구동시키고 있다.On the other hand, the fuel used for ship engines is a combination of high-grade MGO and low-fuel HFO. When countries regulate the use of sulfur-containing HFOs, MGOs are used to operate engines at sea or port. I'm driving it.

이와 같이 MGO와 HFO의 연료를 겸용으로 사용함에 따라, 이들 이종의 연료를 각각 엔진측으로 공급시켜 주는 시스템이 구비되어 있으나, 종래 HFO의 연료를 사용하다가 MGO 연료로 전환하는 시스템이 작업자가 직접 연료의 점도를 측정하면서 수작업으로 밸브를 개폐하는 시스템으로 이루어져 있기 때문에 밸브의 개폐가 수작업으로 진행함에 따라 야기되는 불편함이 있다.As the fuel of the MGO and the HFO are used in this way, a system is provided for supplying these heterogeneous fuels to the engine side. However, the system for converting the fuel to the MGO fuel using the HFO fuel has been performed by the operator. Since the system consists of a system for manually opening and closing the valve while measuring the viscosity, there is an inconvenience caused by opening and closing the valve manually.

즉, 연료의 점도를 작업자가 수시로 체크해야 하고, 체크된 연료 점도에 따라 밸브의 개폐동작을 수작업으로 진행해야 하기 때문에, 작업자가 항상 상주하고 있어야 하는 문제점이 있으며, 작업자의 부주의로 인해 HFO와 MGO 전환시 HFO 연료가 MGO 연료탱크로 유입되는 문제점이 발생될 뿐만 아니라, 이러한 것을 방지하기 위해서는 3개의 밸브를 수작업으로 제어해야 함으로써 밸브의 제어작업에 따른 작업성 저하를 가져오는 문제점이 있다.
That is, since the operator should check the viscosity of the fuel from time to time, and the opening and closing operation of the valve must be performed manually according to the checked fuel viscosity, there is a problem that the operator should always be present, and HFO and MGO due to the carelessness of the operator In addition to the problem that HFO fuel is introduced into the MGO fuel tank during the conversion, there is a problem that the three valves must be manually controlled in order to prevent such a problem, resulting in a decrease in workability due to the control operation of the valve.

본 발명은 HFO와 MGO의 연료 전환시 발생되는 문제점을 해결하기 위해 안출된 것으로서, 3개의 밸브가 각각 엔진의 온도를 감지하는 제어부에 의해 자동으로 개폐되도록 함으로써 HFO 연료에서 MGO 연료의 전환작업이 자동으로 이루어짐에 따른 작업효율성 및 연료 전환의 용이성을 향상시킬 뿐만 아니라, 엔진온도를 제어부가 감지하여 연료의 전환이 이루어지기 때문에 연료의 점도에 따른 밸브의 개폐가 자동으로 이루어져 연료의 전환성이 크게 향상되며, 온도차가 설정값 이상으로 급격하게 변할 경우 제어부에서 밸브를 역방향으로 전환하여 온도가 급격하게 변하는 것을 방지하여 연료의 적절한 점도가 유지되도록 한 선박엔진의 연료공급 시스템을 제공함에 그 목적이 있다.
The present invention has been made to solve the problem that occurs when switching the fuel between the HFO and MGO, the three valves are automatically opened and closed by the control unit for sensing the temperature of the engine, respectively, the conversion of the MGO fuel in the HFO fuel is automatically In addition to improving the work efficiency and ease of fuel conversion, the control of the engine temperature is sensed by switching the fuel is made to open and close the valve automatically according to the viscosity of the fuel is significantly improved fuel conversion. It is an object of the present invention to provide a fuel supply system of a ship engine that maintains an appropriate viscosity of fuel by preventing a sudden change in temperature by switching a valve in a reverse direction when a temperature difference suddenly changes above a set value.

It detects the temperature of the two open valve 50 and the engine inlet to which the main valve is connected to selectively supply any one of the MGO fuel stored in the MGO fuel tank or HFO fuel stored in the HFO fuel tank to the main valve side. It is configured to include a fuel supply control unit (100).

상기 연료공급제어부(100)는, 상기 메인밸브(10)에 구성되는 온도센서(20)와, 상기 온도센서(20)와 전기적으로 연결되어 메인밸브(10)가 연결된 엔진입구의 온도를 감지하는 제어부(30)를 포함하도록 구성된다. The fuel supply control unit 100 is connected to the temperature sensor 20 of the main valve 10 and the temperature sensor 20 to sense the temperature of the engine inlet to which the main valve 10 is connected. It is configured to include a control unit 30.

상기 메인밸브(10)와 제1개폐밸브(40) 및 제2개폐밸브(50)는 3웨이 밸브로 구성된다.The main valve 10, the first open / close valve 40, and the second open / close valve 50 are configured as a 3-way valve.

이에 따라, 메인밸브(10)와 제1개폐밸브(40) 및 제2개폐밸브(50)에 연결된 MGO 공급관(13) 또는 HFO 공급관(14) 및 MGO 회수관(15) 또는 HFO회수관(16)측으로 조건에 의해 각각 개폐되어 MGO 연료탱크(11)에 저장된 MGO 연료가 선박엔진측으로 공급되거나 또는 HFO 연료탱크(12)에 저장된 HFO 연료가 선박엔진측으로 공급되도록 한다.Accordingly, the MGO supply pipe 13 or the HFO supply pipe 14 and the MGO recovery pipe 15 or the HFO recovery pipe 16 connected to the main valve 10 and the first open / close valve 40 and the second open / close valve 50 are thus provided. The MGO fuel stored in the MGO fuel tank 11 is supplied to the ship engine side or the HFO fuel stored in the HFO fuel tank 12 is supplied to the ship engine side.

이때, 제1개폐밸브(40) 및 제2개폐밸브(50)는 3웨이(way) 방식의 체크밸브 또는 솔레노이드밸브로 구성될 수 있음은 물론이며, 상기 메인밸브(10)는 상기 제어부(30)와 전기적으로 연결되어 개폐동작이 상기 제어부(30)로부터 전달되는 전기적인 신호에 의해 이루어진다.
At this time, the first opening and closing valve 40 and the second opening and closing valve 50 may be configured as a check valve or a solenoid valve of a three-way (way) method, the main valve 10 is the control unit 30 ) Is electrically connected to the opening and closing operation is performed by an electrical signal transmitted from the controller 30.

상기와 같이 구성된 본 발명인 선박엔진의 연료공급 시스템은, 메인밸브(10)가 설치되는 선박엔진의 온도가 온도센서(20)에 의해 감지되어 상기 제어부(30)측으로 전달되면, 상기 제어부(30)에 의해 온도센서(20)에 의해 감지된 온도값을 통해 상기 MGO 공급관(13) 또는 HFO 공급관(14) 중 어느 하나의 공급관을 통해 각각의 연료가 선택되어 메인밸브(10)측으로 공급됨으로써 선반엔진에 필요한 동력이 전달된다.The fuel supply system of the ship engine of the present invention configured as described above, when the temperature of the ship engine in which the main valve 10 is installed is sensed by the temperature sensor 20 and transmitted to the control unit 30 side, the control unit 30 Each fuel is selected through the supply pipe of any one of the MGO supply pipe 13 or the HFO supply pipe 14 through the temperature value detected by the temperature sensor 20 by the supplied to the main valve 10 side shelf engine The necessary power is transmitted.

즉, 선박이 해상을 항해하는 도중에 저급연료인 HFO 연료를 사용하다가, 연료유 황함유량 규제구역에서 항해 또는 정박할 경우 고급연료인 MGO 연료로 전환하여 사용하게 되는데, 이때, HFO 연료에서 MGO 연료의 전환작업이 상기 온도센서(20)에 의해 감지된 온도변화에 따른 밸브의 개폐동작에 의해 이루어진다.In other words, when the vessel uses the low-fuel HFO fuel while sailing at sea, when it sails or anchors in the fuel oil sulfur content area, it converts to high-grade fuel MGO fuel. The switching operation is performed by the opening and closing operation of the valve according to the temperature change detected by the temperature sensor 20.

예를 들어, HFO 연료만을 사용할 경우에는, 상기 제1개폐밸브(40)는 HFO 회수관(16)측으로만 개방되고 제2개폐밸브(50)는 닫혀지며 상기 메인밸브(10)는, HFO 공급관(14)측으로만 개방되기 때문에, HFO 연료탱크(12)에 저장된 HFO 연료가 상기 HFO 공급관(13)을 통해 메인밸브(10)측으로 전달되어 엔진을 출력시키고, 남은 HFO 연료는 다시 상기 제1개폐밸브(40)에 의해 HFO 회수관(16)측으로 유로되어 상기 HFO 연료탱크(12)측으로 유입된다.For example, when only HFO fuel is used, the first opening / closing valve 40 is opened only to the HFO return pipe 16 side, the second opening / closing valve 50 is closed, and the main valve 10 is the HFO supply pipe. Since only the side 14 is opened, the HFO fuel stored in the HFO fuel tank 12 is delivered to the main valve 10 side through the HFO supply pipe 13 to output the engine, and the remaining HFO fuel is again opened and closed. The valve 40 flows to the HFO recovery pipe 16 side and flows into the HFO fuel tank 12 side.

또한, HFO 연료에서 MGO 연료로 전환시에는 메인밸브(10)가 MGO 공급관(13)측으로 소정 시간에 걸쳐 개방되고, 제1개폐밸브(40)는 MGO 회수관(15)측으로 개방되며, 제2개폐밸브(50)는 닫혀진 상태를 유지함으로써, MGO 연료를 메인밸브(10)측으로 공급한다. 이어서, MGO 연료료의 전환이 완료되면, 닫혀진 제2개폐밸브(50)를 개방하여 남은 MGO 연료를 다시 MGO 연료탱크(11)로 유로 순환시킨다.In addition, when switching from HFO fuel to MGO fuel, the main valve 10 is opened to the MGO supply pipe 13 side over a predetermined time, the first opening and closing valve 40 is opened to the MGO recovery pipe 15 side, the second The on-off valve 50 maintains the closed state, thereby supplying the MGO fuel to the main valve 10 side. Subsequently, when the switching of the MGO fuel material is completed, the closed second open / close valve 50 is opened to circulate the remaining MGO fuel to the MGO fuel tank 11 again.

이때, HFO와 MGO의 연료 전환시 50분 내지 70분 동안 진행될 수 있다. 예를 들어, 총 1시간 동안 진행되도록 셋업 될 수 있으며, 이 경우 메인 밸브(10)는 매 분마다 1/60%씩 오픈 또는 클로즈된다.At this time, when the fuel conversion of the HFO and MGO may proceed for 50 to 70 minutes. For example, it can be set up to run for a total of 1 hour, in which case the main valve 10 is opened or closed by 1/60% every minute.

또한, 상기 메인밸브(10)와, 제1개폐밸브(40) 및 제2개폐밸브(50)는, 상기 제어부(30)에 의해 역방향(close) 및 정방향(open)이 제어되는 바, 상기 메인밸브가 연결된 엔진입구의 온도 변화율이 1 내지 4℃/min이면 메인밸브(10)가 역방향으로 닫혀지도록 상기 제어부에 의해 제어되고, 상기 메인밸브(10)가 연결된 엔진입구의 온도 변화율이 0.4 내지 0.6℃/min로 감소되면 다시 정방향으로 개방되도록 제어된다.In addition, the main valve 10, the first open / close valve 40 and the second open / close valve 50 are controlled by the control unit 30 in a reverse direction and an open direction. When the temperature change rate of the engine inlet to which the valve is connected is controlled by the controller so that the main valve 10 is closed in the reverse direction when the temperature change rate of the engine inlet is 1 to 4 ° C / min, and the temperature change rate of the engine inlet to which the main valve 10 is connected is 0.4 to 0.6. Once reduced to ° C / min it is again controlled to open in the forward direction.

이에 따라, 엔진입구에서 1분 내에 온도 변화율이 1 내지 4℃/min가 되면, 연료의 점도가 급격하게 변동되기 때문에, 메인밸브(10)의 궤도를 역방향(close)으로 제어하여 온도 변화를 감소시키고, 온도 변화율이 0.4 내지 0.6℃/min로 감소되면 메인밸브(10)를 다시 정방향(open)으로 제어하여, MGO 연료로 전환한다. 이와 같이, 엔진입구에서의 온도변화를 실시간으로 감지하고, 온도가 소정값 이상으로 급격하게 변하면 메인밸브(10)를 역방향으로 제어함으로써, 온도가 급격히 변하는 것을 방지할 수 있다. 따라서, 연료의 적절한 점도를 유지할 수 있다.
As a result, when the temperature change rate reaches 1 to 4 ° C./min within 1 minute at the engine inlet, the viscosity of the fuel fluctuates rapidly, thereby reducing the temperature change by controlling the trajectory of the main valve 10 in a reverse direction. When the rate of change of temperature is reduced to 0.4 to 0.6 DEG C / min, the main valve 10 is controlled in the open direction again to switch to the MGO fuel. As described above, when the temperature change at the engine inlet is sensed in real time, and the temperature changes abruptly above the predetermined value, the main valve 10 is controlled in the reverse direction, thereby preventing the temperature from changing rapidly. Thus, the proper viscosity of the fuel can be maintained.
