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 ).
