US 2026/0145978 A1 · BATCH FEEDSTOCK DELIVERY

Abstract

A batch feedstock delivery system, a glass manufacturing system that includes the batch feedstock delivery system, and a method of delivering a segregated batch feedstock to a submerged combustion melter and producing molten glass are disclosed. The batch feedstock delivery system includes a plurality of raw material containers and a batch conveyor, but does not include a batch mixer, and the segregated batch feedstock is produced at the batch feedstock delivery system. The segregated batch feedstock includes identifiably distinctive portions of sand, soda ash, and limestone and may optionally also include cullet. The segregated batch feedstock that is prepared at the batch feedstock delivery system is conveyed towards the submerged combustion melter, introduced into the submerged combustion melter, and melted in the submerged combustion melter to produce molten glass.

Dependent claims

A method of delivering a batch feedstock to a submerged combustion melter and producing molten glass, the method comprising:

storing sand, soda ash, and limestone in a first raw material container, a second raw material container, and a third raw material container, respectively;
discharging sand, soda ash, and limestone from the first, second, and third raw material containers, respectively, onto a batch conveyor to form a segregated batch feedstock on the batch conveyor, the segregated batch feedstock comprising distinct portions of sand, soda ash, and limestone;
conveying the segregated batch feedstock downstream of the first, second, and third raw material containers and towards a submerged combustion melter;
and
introducing the segregated batch feedstock into the submerged combustion melter and melting the segregated batch feedstock within the submerged combustion melter to produce molten glass.

A method of delivering a batch feedstock to a submerged combustion melter and producing molten glass, the method comprising:

discharging sand from a first raw material conveyor onto a batch conveyor;
discharging soda ash from a second raw material conveyor onto the batch conveyor;
discharging limestone from a third raw material conveyor onto the batch conveyor, wherein the sand, soda ash, and limestone discharged from the first, second, and third raw material containers, respectively, form a segregated batch feedstock on the batch conveyor that comprises distinct portions of sand, soda ash, and limestone;
conveying the segregated batch feedstock towards a submerged combustion melter on the batch conveyor, the submerged combustion melter including a tank and one or more submerged burners received by the tank, and wherein the tank defines a reaction chamber that contains a glass melt;
introducing the segregated batch feedstock into the submerged combustion melter and melting the segregated batch feedstock within the glass melt to produce molten glass;
and
discharging a molten glass output out of the submerged combustion melter, the molten glass output comprising molten glass that includes between 10 vol % and 60 vol % of gas bubbles.
