Ship waste heat power generation system utilizing waste heat from ships

A ship waste heat power generation system in a ship comprising:

• a first heat exchanger (310);
• a second heat exchanger (320);
• an economizer (500);
• a suction pump (200);
• a boiler (610);
• a first circulation pump (330);
• a second circulation pump (410);
• a seawater intake wherein the seawater intake providing a seawater;
• a first freshwater loop passing through an engine;
• a second freshwater loop;
• and
• a working fluid loop including a working fluid, wherein:
• the first heat exchanger (310) transfer heat between the first freshwater loop comprising a first freshwater and the seawater introduced via the suction pump (200);
• the second heat exchanger (320) transfers heat between the first freshwater loop and the second freshwater loop;
• the first circulation pump (330) circulates the first freshwater between the first heat exchanger (310) and the second heat exchanger (320);
• and
• the second circulation pump (410) circulates a second freshwater between the second heat exchanger (320) and a first evaporator (131),
• wherein an Organic Rankine Cycle (100′) comprises:
• the first evaporator (131) configured to heat the working fluid with the second freshwater;
• and
• a second evaporator (133) configured to heat the working fluid;
• and
• wherein the second evaporator (133) is connected in series with the first evaporator (131);
• a turbine (140) rotated by the working fluid heated by the second evaporator (133) and a generator (150) generating electricity by the rotation of the connected turbine (140);
• and
• a condenser (110) configured to liquefy the working fluid discharged from the turbine (150) coupled to the generator (140).
