A waste heat recovery system for a vessel for supplying to a plurality of scroll expanders which are connected in parallel to one another, steam generated by a heat exchanger using waste heat from a main machine as a heat source, may include gate valves corresponding to respective scroll expanders and an electronic controller which controls the number of the scroll expanders which drives based on flow volume of the steam by opening or closing of the gate valves.

The present invention relates to a ship waste heat power generation system utilizing waste heat from ships. Specifically, the present invention relates to a ship waste heat power generation system utilizing waste heat from ships, wherein recovers exhaust gas waste heat and engine cooling water waste heat from ships using various fuels such as diesel, LNG, and dual-fuel. The recovered waste heat is used as a heat source, while seawater serves as the heat sink, generating electricity through the Organic Rankine Cycle (ORC). By combining exhaust gas waste heat and engine cooling water waste heat, which have different waste heat temperatures, in parallel or series to reduce the evaporation heat capacity, the ORC output is enhanced.
