Abstract: 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).

Abstract translation: 一种用于加热玻璃的方法和装置，其中玻璃（4）从玻璃（4）的上方和下方在回火炉（1）中的辊（3）上被加热。 至少玻璃（4）的上表面被相对于玻璃（4）的表面基本垂直地指定的热空气射流加热。 空气喷射器主要通过从炉内吸入空气，并将从回火炉（1）的内部吸入的空气相对于回火炉（1）中的压力加压至超过0.1巴的过压， 。
