Abstract
Submerged combustion systems and methods of use to produce foamed glass. One system includes a submerged combustion melter having an outlet, the melter configured to produce an initial foamy molten glass having a density and comprising bubbles filled primarily with combustion product gases. The initial foamy molten glass is deposited directly onto or into a transport apparatus that transports the initial foamy molten glass to a downstream processing apparatus. An intermediate stage may be included between the melter and the transport apparatus. One intermediate stage is a channel that includes gas injectors. Another intermediate stage is a channel that produces an upper flow of a less dense glass and a relatively more dense glass lower flow. The upper flow may be processed into foamed glass products, while the more dense flow may be processed into dense glass products.
