Patent number: 11820699Abstract: An apparatus for manufacturing glass includes a furnace. A doghouse of the furnace receives and melts solid-glass forming material using one or more submerged combustion burners. An elongated tank positioned downstream of the doghouse includes a melting chamber, a refining chamber, and a thermal conditioning. The melting chamber has in inlet through which molten glass is received from the doghouse. The refining chamber is positioned downstream of the melting chamber and receives molten glass from the melting chamber. The thermal conditioning chamber is positioned downstream of the refining chamber and receives molten glass from the refining chamber. Additionally, the thermal conditioning chamber delivers molten glass to a glass forming machine.Type: GrantFiled: September 28, 2020Date of Patent: November 21, 2023Assignee: Owens-Brockway Glass Container Inc.Inventors: Zhongming Wang, Carl Lucas Fayerweather, Kevin Xin Yu, Shivakumar S. Kadur, Dinesh Gera

Patent number: 10807896Abstract: A process and apparatus for manufacturing glass. A mixture of solid glass-forming materials comprising at least one fining agent are introduced into a doghouse located upstream of an elongated tank. The glass-forming materials are melted in the doghouse at a temperature at or above a fining-onset temperature of the at least one fining agent by application of heat from one or more submerged combustion burners. The resulting molten glass is relatively foamy and may comprise greater than 25 vol. % gas bubbles. The molten glass is directed from the doghouse into an upstream end of the tank where it is refined to produce molten glass having on average less than 20 seeds per ounce.Type: GrantFiled: March 15, 2018Date of Patent: October 20, 2020Assignee: Owens-Brockway Glass Container Inc.Inventors: Zhongming Wang, Carl L. Fayerweather, Kevin X Yu, Shivakumar S Kadur, Dinesh Gera

Patent number: 10118852Abstract: A glass furnace includes a furnace chamber for containing glass melt and a conveyor for receiving glass batch material and feeding the glass batch material to the furnace chamber. A dam wall is disposed with respect to the conveyor such that batch material from the conveyor must flow upward over the dam wall before entering the furnace chamber. The top of the dam wall may be below the level of the melt pool in the furnace chamber.Type: GrantFiled: October 12, 2017Date of Patent: November 6, 2018Assignee: Owens-Brockway Glass Container Inc.Inventors: Zhongming Wang, Scott Weil, Tilak Gullinkala, Udaya Vempati, Shivakumar S.

Patent number: 10029934Abstract: A glass furnace includes a furnace chamber including a side wall and a bottom wall and containing a pool of glass melt having a melt level. A batch feed hopper is adjacent to the side wall of the furnace chamber to supply batch material under gravity to a bottom of the hopper. A feed opening is in the side wall of the furnace chamber and feeds batch material from the bottom of the hopper to the pool of glass melt below the melt level. A conveyor is proximate the bottom wall of the hopper and feeds the batch material from the bottom of the hopper through the feed opening and into the furnace chamber.Type: GrantFiled: October 13, 2017Date of Patent: July 24, 2018Assignee: Owens-Brockway Glass Container Inc.Inventors: Zhongming Wang, Scott Weil, Tilak Gullinkala, Udaya Vempati, Shivakumar S.
