Abstract
This study was performed to find out the possibility that hot waste water from a thermoelectric power plant can be applied to Organic Rankine Cycle (ORC) by comparing the performance characteristics for use of the ocean surface water ($25^{\circ}C$) and hot waste water ($35^{\circ}C$) as a secondary fluid. The parameters considered in this study are four; superheating temperature, subcooling temperature, turbine efficiency, and pump efficiency. Main results of this study are summarized as follows : Overall efficiency of applying hot waste water to ORC is 87% higher than that of surface water. Thus it could be confirmed that hot waste water of the thermoelectric power plant can be applied to ORC.
