  • Molten salt for parabolic trough applications: system simulation and scale effects

    The trend of solar thermal power plant engineering towards lower investment and energy costs leads to a demand for higher operating temperatures in the plant cycle. The use of molten salts withstanding temperatures up to 550 °C is considered for use in CSP plants, in particular for parabolic trough systems. In thermal storage systems fluids as “Solar Salt” (NaNO3/KNO3) are already ...

  • Experimental investigations and comparison of energy and exergy efficiencies of the box type and Solar Parabolic Cooker

    In this paper two different types of solar cookers namely simple box-type and parabolic solar cooker with its focus inside cooker, is investigated experimentally. Experiments were done at roof top of Renewable Energy Lab, Department of Mechanical Engineering, Institute of Technology, Banaras Hindu University (BHU), Varanasi, India. For comparison, these two cookers were kept on a single platform ...
