(b) An ocean thermal gradient electric generating system (OTEC) is proposed for siting in Oman. This system would operate a heat engine driven by heat flow from warm ocean water (cooled from 27°C to 25 °C in the heating heat exchanger of the system), and cooled by heat flow to cold ocean water (which is heated from 3 °C to 5 C in the cooling heat exchanger of the system). The ocean water used in the different parts of the...

04: An Ocean Thermal Energy Converter (OTEC) pumps 200 m/s through a heat exchanger in which the temperature (expressed in Kelvins) drops by 1 %. All the heat extracted is delivered to the ammonia boiler. The ammonia temperature, THT, at the turbine inlet is equal to the mea temperature of the water in the warm water heat exchanger minus 1 K. The temperature, Tcr, of the ammonia leaving the turbine is kept at 10°C by the cooling effect of 250...
