Molten salt storage tank is one of the core equipment of solar thermal power station. The design of thermal insulation layer of molten salt storage tank plays an important role in its safety and economy. It is of great commercial value and academic significance to study the heat transfer performance of the insulating layer of molten salt storage tank. In this paper, the heat transfer models of molten salt storage tank, external insulation layer and tank foundation are established. The temperature distribution and heat loss of the tank are studied. The influence of the insulation nails on the heat transfer performance of the insulation layer is analyzed. The results show that the maximum heat loss lies in insulation layer of the tank wall. Besides, the thickness of the insulating layer greatly influences the temperature drop of molten salt and the time required for steady-state heat transfer. Reasonable setting the length of insulation nail can effectively reduce the surface temperature and heat loss of the insulating layer of molten salt storage tank.
