Abstract:
1. An apparatus for conditioning molten glass comprising: a flow channel defined by a floor, a roof, and a sidewall structure connecting the floor and roof; the flow channel divided into a plurality of serial sections by a series of skimmers extending generally substantially vertically downward a portion of a distance between the roof and floor; one or more high momentum combustion burners positioned immediately upstream of each skimmer in either the roof or sidewall structure, or both, to burst at least some foamed material retained behind the skimmers and floating on top of a molten mass of glass flowing in the flow channel by heat and/or direct impingement thereon; and one or more low momentum combustion burners positioned immediately downstream of each skimmer in either the roof, the sidewall structure, or both, and positioned to transfer heat to the molten mass of glass without substantial interference from the foamed material.
