Method and apparatus for heating glass |
摘要 |
A method and apparatus for heating glass, in which glass (4) is heated upon rollers (3) in a tempering furnace (1) from above and below of the glass (4). At least the upper surface of the glass (4) is heated with hot air jets directed substantially perpendicularly relative to the surface of the glass (4). The air jets have been provided by sucking air mainly from the inside of the furnace and by pressurizing the air taken from the inside of the tempering furnace (1) to an overpressure of over 0.1 bar relative to the pressure in the tempering furnace (1).
