Full Description

Solar ponds provide inexpensive means for collecting and storing solar heat at temperatures below 100 deg C (212 deg F). 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 electric generation process is on the order of 1%. This work is concerned with the use of heat from solar ponds to generate process steam, which can 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 coefficient of performance (COP) of about 0.5. Describes the operation of the heat transformation process and provides quantitative results on efficiencies and temperatures of the output steam.
