由于熔融盐使用温度高、热稳定性和传热性能好,被认为是太阳能塔式发电系统和新一代槽式发电系统中最有前途的传热蓄热介质之一。本文通过搭建高温熔融盐传热试验台,成功实现了LiNO_3熔融盐与导热油的强制对流换热试验循环,得到了总的对流换热系数,初步得到了在旺盛紊流区熔融LiNO_3在不同雷诺数下对应的努塞尔数。
The appropriate heat transfer fluid is a key technological issue for the future success of solar thermal technologies.Molten salt as the heat transfer fluid is considered to be one of the most promising candidates used in power tower plant and trough power plant because of the properties of high working temperature,high thermal conductivity,and thermal stability.In this paper,a high temperature molten salt circular system was built to study the heat transfer mechanisms of molten salts.We first choose molten...
