Waste Heat Source Profiles for Marine Application of Organic Rankine Cycle

The maritime industry will continue to see increasing regulatory requirements reduce carbon emissions from ships’ operations. Improving the energy efficiency of ships with waste heat recovery systems based on organic Rankine cycle (ORC) is an attractive way meet these tightening requirements. operational profile a ship has huge influence feasibility installing ORC onboard as it affects source diesel engines. However, date, scant attention been paid examining effects that marine application both difficult and expensive obtain. present paper aims describe methodology can overcome this problem by developing generic speed defines ship’s profile. This works together fit-for-purpose engine model derive used input thermoeconomic analysis justify installation ORC. proposed allows for objective comparison subjected variations in Furthermore, optimum design be identified payback time expectations different shipowners.
