COOLER FOR SHAFT FURNACE Abstract of the disclosure A cooler for a shaft furnace comprises a metal plate adapted to protect the furnace walls from the heat effect and arranged in the way of heat flow and a means for cooling said plate, made in the form of metal pipes filled with a coolant and sealed at the ends thereof. The coolant-filled ends of the pipes are rigidly fixed to the plate, the coolant-free ends of said pipes being mounted within a cooling chamber with the coolant circulating therethrough. The cooling chamber is arranged exteriorly of the furnace wall. he coolant-free ends of the pipes are disposed slightly above those filled with the coolant. The plate is formed of two layers, namely, a high-heat-conducting layer and a low-heat-conducting one, the former facing the furnace working space and the latter being presented to the furnace wall. The interfacial plane of the layers is parallel to the longitudinal axis of the pipes. The present invention can be advantageously used for the protection of blast-furnace shells.
