Patent ID: 7290405

Claim:
A method for transferring heat onto glass in a furnace used for thermal treatment of the glass, comprising the steps of: transferring the glass into the furnace on a path of rollers located in a roller space, heating the glass by heating elements located inside of the furnace, the heating step including transferring radiant heat of the heating elements onto the glass and transferring convective heat onto the glass by air blown through blowers, said convective heat transferring step further including separating, by a partition wall, the glass being heated in the roller space from an air circulation space, separating the air circulation space into a first suction chamber and a second pressure chamber, and circulating air to heat a surface of the glass with the blowers by (a) sucking air from the first suction chamber and blowing the air into the second chamber, (b) leading the air from the second pressure chamber onto the glass in the roller space, and (c) leading the air from the glass in the roller space into the first suction chamber.
