ABSTRACT:
A forced convection heating apparatus and process for heating glass sheets therewithin. The apparatus includes at least one gas burner for producing hot combustion gases which is to be distributed to the top and/or bottom surfaces of a glass sheet within the apparatus housing. Spent hot working fluid, which has impinged the top and bottom surfaces of the glass sheet, is drawn into a mixing chamber operably positioned about a gas burner. The spent hot working fluid and newly produced hot combustion gases from the gas burner are mixed within the mixing chamber and then distributed toward and into operable contact with at least one of the top and bottom surfaces of the glass sheet.
