Abstract:
1. A system for heat treatment of glass, comprising: a heating chamber; at least one heating means for radiant heating within the heating chamber; a compressor located outside of the heating chamber; and a guiding means for supplying compressed gas from the compressor to the heating chamber, wherein the guiding means comprises a plurality of air flow amplifiers positioned within the heating chamber for producing gas swirls in the heating chamber, in order to additionally heat the glass by intensified convection, wherein at least one gas swirl brushes against or flows around at least one heating means, wherein each air flow amplifier includes a tubular component with an open inlet side and an open outlet side that defines a mixing section with a constant clear diameter or cross section for conveying gas by in-flowing compressed gas and for mixing chamber gas and compressed gas, wherein the compressed gas is supplied to each air flow amplifier in a through-flow and central direction by a nozzle associated with each air flow amplifier on the inlet side thereof, and wherein the air flow amplifiers or their mixing sections are oriented at least substantially vertically.
