ABSTRACT:
A method and furnace for heating a glass sheet by lower electric resistance elements (50) supported by a furnace housing (12) below a roll conveyor (40) and by supplying a gas burner heated hot gas flow from a forced convection heater (56) that provides a dominant mode of external heat for heating the conveyed glass sheet from above. The furnace can also be manufactured by retrofitting an electric resistance heater type glass sheet furnace.
