Description

양방향 구동력을 전달받는 선박 엔진용 폐열회수장치{Waste Heat Recovery Apparatus for Ship Engine for transmitting Two Way Driving Force}Waste Heat Recovery Apparatus for Ship Engine for transmitting Two Way Driving Force}

본 발명은 양방향 구동력을 전달받는 선박 엔진용 폐열회수장치에 관한 것으로서, 더욱 상세하게는 발전기의 양쪽에 스팀터빈과 파워터빈을 각각 배치하여 어느 한쪽의 터빈이 문제가 발생하더라도 발전기의 구동이 가능하도록 한 것이다.
The present invention relates to a waste heat recovery apparatus for a ship engine receiving bidirectional driving force, and more particularly, to arrange a steam turbine and a power turbine on both sides of a generator so that the generator can be driven even if one of the turbines has a problem. It is.

일반적으로, 선박에 설치되는 폐열회수장치는 도 1에 도시된 바와 같이, 메인 엔진으로부터 발생되는 배기가스에 의해 구동되는 파워터빈(10)과, 보일러로부터 발생되는 스팀의 일부(폐열)에 의해 구동되는 스팀터빈(20)과, 이러한 파워터빈(10)과 스팀터빈(20)에 의한 동력을 전달받아 발전이 이루어지도록 하는 발전기(30)로 이루어진 구조이다, In general, the waste heat recovery apparatus installed in the ship is driven by a power turbine 10 driven by the exhaust gas generated from the main engine and a part of the steam generated from the boiler (waste heat), as shown in FIG. It is a structure consisting of a steam turbine 20 and a generator 30 to receive power from the power turbine 10 and the steam turbine 20 to generate power,

또한, 파워터빈(10)과 스팀터빈(20)의 사이와, 스팀터빈(20)과 발전기(30) 사이에는 각각 감속기어(40)(60)가 연결되고, 감속기어(40)와 스팀터빈(20)사이에는 파워터빈(10)의 동력을 단속하는 클러치(50)가 연결된 구조를 가진다. In addition, between the power turbine 10 and the steam turbine 20, and between the steam turbine 20 and the generator 30, the reduction gear 40, 60 is connected, respectively, the reduction gear 40 and the steam turbine Between the (20) has a structure in which the clutch 50 to control the power of the power turbine 10 is connected.

또한, 파워터빈(10)과 스팀터빈(20)에 각각 윤활유를 공급하도록 하는 통합 윤활유 저장탱크(70)가 갖추어진 구조를 가진다.In addition, the power turbine 10 and the steam turbine 20 has a structure equipped with an integrated lubricating oil storage tank 70 for supplying lubricating oil, respectively.

이러한 종래의 폐열회수장치는 발전기(30)에 동력을 전달하는 파워터빈(10)과 스팀터빈(20)이 직렬로 연결되어 있는 구조이기 때문에, 만일 스팀터빈(20)에 공급되는 스팀양이 부족하거나 또는 스팀터빈(20) 자체에 문제가 발생하는 경우에는 파워터빈(10)을 통해 동력을 전달하더라도 발전기(30)에 동력을 제대로 전달하지 못하거나 아예 전달하지 못하게 된다.Since the conventional waste heat recovery apparatus has a structure in which the power turbine 10 and the steam turbine 20 which transmit power to the generator 30 are connected in series, the amount of steam supplied to the steam turbine 20 is insufficient. Or, if a problem occurs in the steam turbine 20 itself, even if power is transmitted through the power turbine 10 will not be able to properly transfer power to the generator 30 or not at all.

더욱이, 하나의 윤활유 저장탱크(70)를 사용하므로, 파워터빈(10) 또는 스팀터빈(20)에 윤활유를 공급하는 과정에서 어느 한쪽에 문제가 발생하면 다른 쪽 윤활유공급에도 영향을 주는 문제점이 있다.
Furthermore, since one lubricant storage tank 70 is used, if a problem occurs in the process of supplying lubricant to the power turbine 10 or the steam turbine 20, there is a problem that affects the supply of the other lubricant. .
