Application of Rankine Bottoming Diesel Engines to Marine Vessels 790644
The use of organic Rankine cycle energy recovery systems can be an effective means of reducing fuel consumption for some types of diesel-powered marine vessels. An organic Rankine cycle diesel bottoming system is capable of recovering the equivalent of from a few percent to more than 20 percent of the base diesel engine output power from the exhaust gas energy. As a more desirable alternative to producing additional shaft horsepower, fuel consumption of the base diesel engine could be reduced by a comparative amount. Analysis indicates that Rankine cycle recovery systems could be cost-effective for diesel marine vessels that operate at high-duty cycle load factors.
