Controllable Solar Flux Heating for Freeze Recovery in Molten Salt Parabolic Trough Collectors

Assessment of a Molten Salt Heat Transfer Fluid in a Parabolic Trough Solar Field

An evaluation was carried out to investigate the feasibility of utilizing a molten salt as the heat transfer fluid (HTF) and for thermal storage in a parabolic trough solar field to improve system performance and to reduce the levelized electricity cost. The operating SEGS1 plants currently use a high temperature synthetic oil consisting of a eutectic mixture of biphenyl/diphenyl oxide. The sco...

Solar Heat in Industrial Processes Integration of Parabolic Trough Solar Collectors in Dairy Plants and Pharmaceutical Plants

Improvements in efficiency of solar parabolic trough

Solar energy is primary source of all type of energy which is present in nature i.e. all the energy derived from it. So, direct utilization of solar energy into useful energy is important. There are so many solar thermal equipments in which concentrating type collector heated the fluid up to 100 to 400C. It is employed for a variety of applications such as power generation, industrial steam gen...

Exergetic and Thermoeconomic Analyses of Solar Air Heating Processes Using a Parabolic Trough Collector

This paper presents a theoretical and practical analysis of the application of the thermoeconomic method. A furnace for heating air is evaluated using the methodology. The furnace works with solar energy, received from a parabolic trough collector and with electricity supplied by an electric power utility. The methodology evaluates the process by the first and second law of thermodynamics as th...
