The present invention relates to a thermal power generation apparatus using exhaust gas of a ship engine, and more particularly, to a thermal power generation apparatus using exhaust gas of a ship engine that generates electric power by using heat of exhaust gas discharged.

일반적으로 선박은 프로펠러에 의해 추진되어 전방 또는 후방으로 움직이게 되며, 여기서 프로펠러는 다양한 동력원을 이용하여 구동하는데, 엔진룸 내에 위치하는 디젤 엔진 또는 스팀 터빈에 의해 구동된다. In general, a ship is propelled by a propeller and moved forward or rearward, where the propeller is driven by various power sources, driven by a diesel engine or a steam turbine located in the engine compartment.

또한, 선박의 운항시에 각종 전자장비의 작동, 공조 시스템 가동, 선실 내의 전력공급 등을 위해 전력이 지속적으로 필요하게 되며, 이러한 전력은 선박의 엔진룸 내에 위치하는 발전기에 의하여 공급된다. In addition, the power is constantly required for the operation of the various electronic equipment, operation of the air conditioning system, supply of power in the cabin, etc. during the operation of the ship, this power is supplied by a generator located in the engine room of the ship.

여기서 디젤 엔진 또는 스팀 터빈 및 발전기의 구동시 배기가스가 발생하게 되며, 선박에는 이러한 배기가스를 배출시키기 위한 펀넬이 구비되어 있다. Here, exhaust gas is generated when driving a diesel engine or a steam turbine and a generator, and a ship is provided with a funnel for discharging such exhaust gas.
