To inhibit sulfuric acid dew point corrosion occurring on a heat transfer surface of a heater when exhaust gas of an internal combustion engine using an oil fuel, such as a heavy oil, which contains a large amount of sulfur contents is used as a heat source fluid in a marine organic rankine cycle power generation system which recovers heat from two or more types of heat source fluids having different temperatures in the heater.SOLUTION: A marine power generation system 1 includes: a circulation circuit LC for circulating a working medium R; a circulation pump 22; a first heater 10 which heats the working medium R with supercharged air A2 from a supercharger 64; a second heater 12 which heats the working medium R with exhaust gas E2 from an exhaust gas economizer 68; an expander 16; a cooler 20; a power generator 18; flow rate adjusting means 40 which adjusts a flow rate of the working medium R; pressure detection means 42 and temperature detection means 44 which make detection related to the working medium R right after the working medium R flows out from the first heater 10; and a fuel type information acquisition part 33 which acquires information on an internal combustion engine 60. The flow rate adjusting means 40 is controlled in reference to the information of the fuel type information acquisition part 33.SELECTED DRAWING: Figure 1

    【課題】温度の異なる2種類以上の熱源流体から加熱器にて熱回収を行う船舶用の有機ランキンサイクル発電システムにおいて、重油など硫黄分を多く含む油燃料を使用する内燃機関の排ガスを熱源流体とする場合に、加熱器の伝熱面に生じる硫酸露点腐食を抑制する。【解決手段】船舶用発電システム1であって、作動媒体Rを循環させる循環回路LCと、循環ポンプ22と、過給機64からの過給空気A2で作動媒体Rを加熱する第1加熱器10と、排ガスエコノマイザ68からの排ガスE2で作動媒体Rを加熱する第2加熱器12と、膨張機16と、冷却器20と、発電機18と、作動媒体Rの流量を調節する流量調節手段40と、第1加熱器10から流出直後の作動媒体Rに対する圧力検知手段42および温度検知手段44と、内燃機関60に対する燃料種情報取得部33と、を備え、燃料種情報取得部33の情報を参照して流量調節手段40を制御する。【選択図】図1
