Abstract
A gas burner (20) disclosed has general utility but has particular utility when utilized in a closely spaced relationship to roller conveyed glass sheets to provide forced convection heating. The burner (20) includes a combustion member (38) in which gas and air are introduced in a tangential relationship with respect to its inner surface to provide a swirling motion that mixes the gas with the air for combustion prior to discharge through outlets (46) to provide the forced convection heating. A glass sheet heated by this gas burner forced convection on the roller conveyor and subsequently cooled has reduced roll-wave distortion and reduced edge distortion as compared to radiantly heated glass sheets.
