The present invention relates to an electric power producing system using waste heat recovery. According to an embodiment of the present invention, the electric power producing system using waste heat recovery comprises: a dual-fuel engine driven by receiving one or more among gas fuel and liquid fuel; an economizer to receive exhaust gas emitted from the dual-fuel engine to produce steam using waste heat of the exhaust gas as a heat source; an auxiliary boiler to receive the liquid fuel to additionally produce steam using combustion heat of the liquid fuel if an amount of the steam produced by the economizer is insufficient; and a steam turbine generator to receive a portion of the steam discharged from the economizer and the auxiliary boiler to produce energy. According to the present invention, since discarded waste heat is recovered to produce electric power, an engine does not need to be operated to produce additional power required for a ship, thereby saving fuel costs.

    본 발명은 폐열회수를 이용한 전력생산 시스템에 관한 것으로, 본 발명의 일 실시예에 따른 폐열회수를 이용한 전력발생 시스템은, 가스연료 및 액체연료 중 어느 하나 이상을 연료로 공급받아 구동되는 이중연료 엔진; 상기 이중연료 엔진에서 배출되는 배기가스를 공급받아 상기 배기가스의 폐열을 열원으로 스팀을 생산하는 이코노마이저; 상기 이코노마이저에서 생산된 스팀의 생산량이 부족할 경우, 액체연료를 공급받아 그 연소열로 스팀을 추가 생산하는 보조보일러; 및 상기 이코노마이저 및 보조보일러에서 배출된 스팀 중 일부를 공급받아 에너지를 생산하는 증기터빈 발전기를 포함한다. 본 발명에 의하면, 버려지는 폐열을 회수하여 전력을 생산하기 때문에 선박에 추가 필요한 전력을 생산하기 위해 엔진을 운전시키기 않아도 되므로, 그에 따른 연료비용을 절약할 수 있는 효과가 있다.
