To provide a marine power generation system that can effectively use energy generated in a ship.SOLUTION: A marine power generation system 1 is used in a ship S comprising an internal combustion engine 11, and an exhaust gas turbine type supercharger 12 for sending supercharged air A1 into the internal combustion engine 11, and comprises: an exhaust gas economizer 31 for generating steam S1 by using exhaust gas E1 from the internal combustion engine 11; and a binary power generator 40 for recovering thermal energy via a circulating working medium, and generating power on the basis of expansion of the working medium. The binary power generator 40 comprises a first evaporator 41A for heating the working medium R1 by exchanging heat between the supercharged air A1 from the supercharger 12 and the working medium R1, and a second evaporator 41B for heating the working medium R1 by exchanging heat between the exhaust gas E1 from the internal combustion engine 11 and the working medium R1. The exhaust gas E1 from the internal combustion engine 11 flows through an exhaust gas turbine that is a driving source for the supercharger 12, the exhaust gas economizer 31, and the second evaporator 41B in this order.SELECTED DRAWING: Figure 1
