Technical Examples

A glass tempering furnace having a chamber, rollers extending laterally within a chamber to form a transport surface for the plate glass, radiant coils positioned along the bottom of the chamber underneath the rollers, a plurality of spaced nozzle assemblies arranged in lateral side-by-side fashion within the chamber above the rollers, and fans coupled to the nozzle assemblies to draw heated air from the chamber and force the heated air onto the top surface of the plate glass. Heating elements, preferably electrically heated rods, extend between each of the nozzle assemblies and are positioned within the return path of the heated air after it is flowed onto the plate glass surface. The air then rebounds from the glass plate prior to the air again being drawn up into the fan and blown back down onto the glass. Air is then again drawn from the furnace chamber and forced through ducting to a nozzle assembly.
