Abstract: Systems and methods provide a cooling device for a blast furnace that may prevent an excessive amount of coolant from entering the blat furnace and may be easily installed in a conventional blast furnace. Systems and methods may provide a cooling device for a blast furnace that may prevent an excessive amount of coolant from entering the blast furnace and may be simple and cost effective to manufacture. The end of a heat pipe (202) that is outside of the furnace may be configured to interact with a heat sink (210). The heat sink (210) may be for example, a separate amount of coolant that is circulated outside of the furnace, an evaporative cooling system, and/or any other system or method of cooling the heat pipe (202) that transfers heat from the heat pipe (202) to the heat sink (210). Because the coolant within the heat pipe (202) is sealed within the heat pipe (202), only the small, fixed amount of coolant that. is within the heat pipe (202) will enter the furnace should the cooling plate (200) rupture.
