PURPOSE:To prevent the mist of molten salt from scattering and to recover and reuse the salt in high purity by mounting an object that receives radiation heat from the molten salt into a hood provided in the upper part of the tank. CONSTITUTION:A plate 1000 which receives the radiation heat from molten salt is mounted horizontally zigzag in a hood 500 above the liquid level of the molten salt in the stage of passing a steel material in the conveyance path 100 in a molten salt tank 200 and recovering the heat therefrom. When the molten salt is bubbled with a bubbling header 300, the mist of the salt scatters from the surface of the molten salt and collides against the plate 1000. The plate 1000 has already the temp. above the solidifying point of the molten salt by receiving the radiation heat of the molten salt and therefore the mist colliding against the plate melts on the surface of the plate 1000 and forms the liquid, the amt. of which increases gradually until the liquid drops by gravity from the plate. The dropped liquid returns in the tank 200 and is reusable immediately. |
