Abstract
A system and a process for heat treatment of glass or other materials where fan air is blown into a heating chamber via propellant air fans and the chamber air is circulated. In order to achieve effective convection, the propellant air fans have cylindrical mixing sections. Additionally, resulting air swirls flow around the heating means which are located in the heating chamber.
