ABSTRACT:
The invention relates to heat exchange devices for cooling the wall and the refractory of a blast-furnace. Such a device comprises a body shaped substantially as a body of revolution and having first and second end walls and a curved wall extending therebetween, the first end wall being a heat-transfer wall, a supply port and a discharge port for heat-transfer fluid, the ports being spaced-apart radially, the supply port being adapted for tangentially supplying the heat-transfer fluid into the body and the discharge port being adapted for tangentially discharging the heat-transfer fluid from the body, so that, in use, the fluid flows between the ports in a spiral path over the inner surface of the first end wall, the body having no internal obstacle to such flow. (FIG. 1)
