A furnace system for smelting ore concentrate and the like which includes a furnace housing provided with wall means which divide the housing into a smelting shaft, an exhaust gas shaft and a settling hearth. The settling hearth and the smelting shaft are separated by a partition wall preventing gaseous interaction therebetween but permitting liquid flow therebetween. In accordance with the invention, the partition wall between the exhaust gas shaft and the smelting shaft, as well as the wall between the settling hearth and the smelting shaft and exhaust gas shaft comprises a supporting frame on which there are a plurality of interengaged cooling elements which are releasably secured to the supporting frame and are provided with means for circulating a coolant therethrough.
In a furnace system for smelting ore concentrate and the like including a furnace housing having wall means dividing the same into a smelting shaft, an exhaust gas shaft and a settling hearth, said settling hearth and said smelting shaft being separated by a partition wall preventing gaseous interaction therebetween but permitting liquid flow therebetween, the improvement which comprises:
In a furnace system for smelting ore concentrate and the like including a furnace housing having wall means therein subject to high thermal stresses at at least one surface thereof, the improvement which comprises:
