IMPROVING AIR-COOLED CONDENSER PERFORMANCE USING WINGLETS AND OVAL TUBES IN A GEOTHERMAL POWER PLANT

Two concepts for improving the heat transfer performance of the air-cooled condensers used in binary geothermal power plants are being developed and tested at the INEEL. These concepts involve (1) replacing the circular tubes with oval tubes and (2) adding strategically located vortex generators (winglets) in the fins. These concepts can be used individually or in unison. Depending on the various design parameters, the heat transfer coefficient can be enhanced by 25–35%, with a minimal increase in pressure drop. The INEEL is also collaborating with several manufacturing companies to improve and commercialize these concepts. This paper summarizes the work completed to date and plans for the future.
