“…The sunlight irradiates to point P on the surface of earth, which is determined by elevation angle h s and azimuth angle λ of the tangent plane. The sun position in the tracking system is calculated by international SPA algorithm whose accuracy is 0.0003° [ 13 , 14 ].…”

Depending on the rotational structure of Fresnel reflector, the rotation angle of the mirror was deduced under the eccentric condition. By analyzing the influence of the sun tracking rotation angle error caused by main factors, the change rule and extent of the influence were revealed. It is concluded that the tracking errors caused by the difference between the rotation axis and true north meridian, at noon, were maximum under certain conditions and reduced at morning and afternoon gradually. The tracking error caused by other deviations such as rotating eccentric, latitude, and solar altitude was positive at morning, negative at afternoon, and zero at a certain moment of noon.

“…Compared with 316L stainless steel, nickel-based superalloy single molten salt corrosion in chloride has been improved, but has not yet reached the expected corrosion resisting effect. The molten salt itself, solar molten salt thermal storage system tend to mix the molten salt medium, because of the characteristics of chemical stability and thermal stability, low vapor pressure, low viscosity [4,6] . The higher vapor pressure of t molten salt, the higher basicity of the dissolution rate of the oxide formed on the surface of the alloy increases, the corrosion rate of the alloy increases [7].…”

In solar thermal storage system, the mixed chloride molten salt with the higher conversion efficiency than a single molten salt, but they are more corrosive than the often used nitride molten salts. In the presents work, aluminide and chromate coating were prepared on the surface of Inconel625 alloy by thermal packing method. The corrosion behaviors of thermal diffusion coating on the surface of Inconel625 alloy in mixed molten salts at 900°C were studied by using XRD and SEM equipped with EDS in the present work. The results showed that both of the two thermal diffusion coatings have sever corrosion in the mixed chloride molten salts, but thermal diffusion Al coating in the mixed chloride molten salt corrosion is more serious than thermal diffusion Cr coating, because Cr2O3is more easily dissolved in the molten salt than Al2O3.
