Thermal Receiving System Introduction
Receiver is the core of thermal receiving system, which absorbs solar energy and converts it into thermal energy by heat transfer media.Molten salt receiver, which uses MS as working medium, is faced with severe conditions such as high temperature, frequent drastic changes between high and low temperature, corrosive environment and so on. In order to ensure the safe and efficient operation of the molten salt receiver, Cosin Solar has been optimizing from many aspects.
Key Technologies
Material Selection
imported high nickel alloy tube, resistant to high temperature, corrosion, thermal stress, thermal fatigue; High absorption coating, improve the absorption rate of solar resources
Control System
ensure that the surface temperature of the receiver is uniform, the receiver control system and the HFCS are deeply coupled, interlock control, and reduce the thermal shock
Structure Design
flexible structure, thermal stress, thermal fatigue; Modular factory prefabrication, avoid on-site processing, ensure the performance of the receiver, improve installation efficiency
Anti-frozenand Anti-blocking
optimize the internal pipeline structure to reduce the occurrence of frozen and blocking conditions; The surface energy of the receiver can be monitored in real time, and the surface temperature can be monitored at any time. The automatic salt control system makes use of the solar field energy to speed salt melting and dredging up under frozen and blocking conditions
