Molten Salt Furnace
Introduction
Under the condition of operating temperature as high as 350-480°C, organic heat carrier cannot be used any more while molten salt like heat carrier should be used.
QXS series molten salt heating furnace is a direct-flow style special industrial furnace which takes coal, oil and gas as fuel and the molten salt as the carrier to transfer heat energy to heat consuming equipments by means of the circulation pump with forced liquid-phase circulation. The molten salt shall be returned to be heated again and the whole system consists of heating furnace, circulation pump and melting system.
