A HFC-245fa Organic Rankine Cycle (ORC) system has been developed to recover heat from marine engines jacket water to convert it to electricity for shipboard consumption.
Ten new Organic Rankine Cycle (ORC) generators using HFC-245fa as working fluid have been installed in a Slovakian district heating plant to increase the on-site efficiency of two cogeneration gas turbines.
