Research on Double Stage-Rankine Cycle for Ocean Thermal Energy Conversion using Ammonia as Working Fluid

摘要

The practical use of Ocean Thermal Energy Conversion (OTEC) isrnrefocused because it is possible to supply stable electric power and arnvariety of integrated applications. This paper investigates on thernthermal performance of Double Stage-Rankine cycle that hasrnindependent equipment respectively in two Rankine cycles. Turbinernpower and thermal efficiency of Double Stage-Rankine cycle is foundrnto be larger than these of Single-Rankine cycle. Moreover, thernmaximum output power of Double Stage-Rankine cycle is found to bernlarger than both these of Single-Rankine cycle and Kalina cycle.
