QGECE research on dry cooling for geothermal power plants

The aim of this paper is to give an overview of the research conducted at QGECE on air-cooled heat exchangers, in general and condensers in particular, for their application in geothermal power plants. The application of metal foam heat exhangers in natural dry cooling towers has been studied in detail. Furthermore, the design of a steel cooling tower is proposed and analyzed. Solar-enhanced dry cooling toer, a concept put forward by QGECE, is examined here. This paper also provides an update on our research on the issue of fouling and dust deposition on air-cooled heat exchangers.
