In the chapter, analysis of various solar thermal systems, such as flat plate collectors, evacuated tube collector, solar concentrating collectors, solar distillation, solar pond, solar dryer, and solar refrigeration have been discussed. Recent trends of development and augmenting the performance of thermal collectors are also emphasized.
Solar thermal collectors have been widely studied, and various new designs were reported. To improve the performance of these solar devices, it is essential to understand the heat transfer behavior of the systems.
For each hour of a year the performance of the plant was calculated, for the hourly values of the solar irradiation (DNI), the actual weather conditions (temperature, pressure) as well as the solar position angles according to the geographic location of the site and the time in the year.
In this work, heat transfer mechanisms involved in solar thermal devices, such as flat plate collector, evacuated tube collector, solar concentrating collectors, solar pond, solar distillation, solar dryer, and solar refrigeration are discussed and important observations made by various researchers are also presented.
If not enough solar energy for solar operation of the power block is available, the HTF can be heated from the storage or the fossil burner and transfer its heat to the water steam cycle. The HTF temperature in the cold headers is 293°C and in the hot headers 393°C.
