Abstract
Abstract Solar ponds provide inexpensive means for collecting and storing solar heat at temperatures below 100°C. The most common application of this heat to date has been the generation of electric power. Due to the thermodynamic limitation set by the relatively low source temperature, the overall efficiency of the electricity generation process is of the order of 1%. This article is concerned with the use of heat from solar ponds to generate process steam, which may be performed at relatively high efficiency. The use of an absorption heat transformer makes it possible to produce low-grade steam from the pond's heat at a COP of about 0.5. The article discusses the operation of the heat transformation process and provides quantitative results on efficiencies and temperatures of the output steam.
