The generator vapor is separated into liquid and vapor in KCS and the resulted power is low. Out of two ORC, heat recovery in OFC is more than ORC and so the exhaust gas temperature is 81.92 °C compared to 97.76 °C in ORC. The highest cycle efficiency is resulted in ORC and more power and exergy efficiency is with OFC.
