ABSTRACT:
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).
