Abstract

Se proporcionan medios para producir agua dulce de agua de mar tanto en el lado de la caldera como el lado del condensador de una planta de energía OTEC. Parte del agua caliente de la superficie del océano se evapora, y su vapor transfiere calor a la caldera del fluido operativo según se condensa el vapor. La condensación del vapor proporciona agua dulce. En el lado del condensador, la condensación del vapor del fluido operativo de la turbina en el condensador libera calor que evapora el agua de mar que corre hacia abajo en la parte exterior de las superficies del condensador. El vapor del agua de mar se condensa por el intercambiador de calor que utiliza la entrada de agua de mar más fría. Cuando el agua de mar fría acepta el calor del vapor de condensación, se hace ligeramente más caliente y proporciona la fuente de agua de mar que acepta calor del condensador. El vapor de condensación en el intercambiador de calor se convierte en agua dulce que se extrae como agua potable.Means are provided for producing freshwater from seawater on both the boiler side and the condenser side of an OTEC power plant. Some of the hot water on the surface of the ocean evaporates, and its steam transfers heat to the boiler of the operating fluid as the steam condenses. Steam condensation provides fresh water. On the condenser side, steam condensation of the turbine operating fluid in the condenser releases heat that evaporates the seawater that runs downward on the outside of the condenser surfaces. Seawater vapor is condensed by the heat exchanger that uses the coldest seawater inlet. When cold seawater accepts the heat of condensation vapor, it becomes slightly hotter and provides the source of seawater that accepts heat from the condenser. The condensation vapor in the heat exchanger is converted into fresh water that is extracted as drinking water.
