Application of Phased Cooling to a Once-Through Cooling System

This paper describes the application of a heat dissipation technique called “phased-cooling” to the cooling of “once-through” river water used in an electric power plant. A thermodynamic model for the situation is developed and the equations applying to the model are given. The performance of the system is analyzed for a summer day in the Southeastern United States. Results of the analysis show that an economically attractive system can be built with less than half of the evaporation loss of cooling towers. This system can meet federal standards.
