An estimation of the performance limits and improvement of dry cooling on trough solar thermal plants

Abstract: a b s t r a c tA study is reported of the potential performance of dry cooling on power generation. This is done in the context of a generic trough solar thermal power plant. The commercial power plant analysis code GateCycle is applied for this purpose. This code is used to estimate typical performance of both wet and dry cooling options. Then it is configured to estimate the performance of ideal wet and dry cooling options. The latter are defined as the condenser temperature being at the ambient wet bulb tem… Show more

“…Cold side temperature should be kept as low as possible, which is limited in practice by the ambient temperature the plant operates in as well as the heat transfer to the ambient environment. 298,299 The Carnot efficiency represents the maximum performance limit, and cannot be achieved by real heat engines. A lower efficiency, called the Chambadal-Novikov efficiency, can be derived for a heat engine with irreversible heat transfer processes operating at maximum power output.…”

“…The typically arid climates in the likely locations for renewable thermal power plants such as Concentrating Solar Thermal (CST) provide the motivation for dry cooling technology optimized for renewable power generation [1][2][3][4]. Due to their low maintenance cost and simple structures, natural draft dry cooling towers (NDDCT) offer a feasible and cost effective option for such applications [5][6][7][8].…”

“…This is a problem where fresh water resources are scarce and expensive. Due to the increased interest in renewable thermal power generation such as the geothermal and solar thermal power plants, where the prospective locations usually lack water, dry cooling technology has received extra attention in recent years [12,[14][15][16][17][18][19][20][21].
