Summary

The self-water supply organic Rankine cycle (ORC) power system is a combination of distillation and hot spring thermal energy conversion; thus, it is able to produce the electric power and water to supply the cooling tower simultaneously. The cycle uses low-pressure steam as a warm heat source produced by the flash evaporation in the vacuumed condition instead of flowing the hot spring water. It acquires to prevent the performance degradation of the evaporator caused by the scaling due to the supersaturated Ca, Si, and so on. In this study, the parametric analysis of a novel hybrid ORC is conducted to show the basic performance (i.e., the power generation and water production to feed to cooling water). The analysis clarified the possibility of up to 3% of distillated water feeding to the cooling water.
