Secondary air nozzle for furnaces

摘要

The secondary air nozzle for furnaces has a curved base body which is provided with pins for holding a ceramic protective casing. A protective strip which projects radially from the base body is arranged along the longest line of curvature proceeding from the nozzle opening until beyond the curved part, its radial dimension corresponding at least to the thickness of the ceramic protective casing. The protective strip is constructed as a rib which projects radially from the base body and is outfitted with pins for supporting the ceramic body.
