A nozzle assembly constituting a burner or blowing nozzle includes, in the region of the discharge opening thereof, a piston-like member which is displaceable by an actuating means into a position of blocking off the discharge opening thereby to prevent same from becoming clogged by slag or metal splashed thereon. When the assembly is mounted in the wall of a metallurgical furnace, the piston-like member may also be adapted to close off the opening in the wall, which communicates with the nozzle assembly, in order also to keep the wall opening open. At least a part of the piston-like member may be caused to oscillate or at least the part thereof which is towards the interior of the furnace may comprise or be coated with a scale-resistant material or may be coated with a material that is difficult to wet.

Nozzle assembly for a metallurgical furnace

Method and apparatus for evaporation cooling in metallurgical furnaces. In order to prevent the formation of heat-insulating layers of vapor, over a large area, between the heat exchange surface (14) and the cooling fluid supplied thereto, the cooling fluid is supplied at a plurality of positions which are distributed over the surface, and the amount of fluid supplied is so restricted that a closed film of fluid covering the entire heat exchange surface (14) can no longer be formed. The fluid is guided to the heat exchange surface (14) by fluid guide means which are in the form of pin members or plates, or by way of a loose filling of particles, which communicate with the heat exchange surface (14) (FIG. 2).
