Glass heating furnace

A glass heating furnace comprising:

• a furnace body, an interior of which is formed with a chamber;
• a plurality of upper heating elements, which are disposed in the chamber, with the center of one upper heating element being separated with the center of a neighboring upper heating element by a first distance;
• a plurality of lower heating elements, which are disposed in the chamber and are located oppositely below the plurality of the upper heating elements, with the center of one lower heating element being separated with the center of a neighboring lower heating element by a second distance;
• and
• a plurality of rollers, which are disposed in the chamber along a transversal axis and are located between the plurality of upper heating elements and the plurality of lower heating elements, with the transversal axis being perpendicular to the axis of the plurality of rollers;
• wherein the center of each upper heating element is configured with an upper normal line which is perpendicular to the transversal axis, the center of at least one lower heating element is disposed between two neighboring upper normal lines, and the center of that lower heating element is not overlapped with those two neighboring upper normal lines;
• or the center of each lower heating element is configured with a lower normal line which is perpendicular to the transversal axis, the center of one upper heating element is disposed between the two neighboring lower normal lines, and the center of that upper heating element is not overlapped with those two neighboring lower normal lines.
