- Parametric Analysis on Hybrid Ocean Thermal Energy Conversion System
抄録
The hybrid OTEC (H-OTEC) cycle is a combined system of a desalination and an OTEC which generates power using the temperature difference between the surface and depth in the ocean. The system is able to produce the electric power and the distilled water from seawater, simultaneously. The cycle uses low pressure steam as warm heat source generated by the flush evaporation in vacuumed condition instead of flowing the surface seawater that acquires: to prevent the performance degradation of the evaporator caused by the fouling due to marine organisms, to improve the heat transfer and to cost reduction by using the stainless steel instead of the titanium for an evaporator. In this study, the effects of each heat exchanger on the performance in the hybrid cycle were clarified by parameter analysis. It conducts to examine the effect of the working fluid flow rate and the evaporator heat transfer performance on the net power generation, exergy efficiency, and water production ratio. As the results, it is confirmed that the net power generation increases with working fluid flow rate. In addition, as the evaporator heat transfer performance increases, the power output and the exergy efficiency is increased, and the maximum performances confirmed in each condition is increased, respectively. Furthermore, the water production ratio increased with the increase in working fluid rate, and the specific power consumption decreased significantly.
