  • Patent number: 10836668
    Abstract: A furnace system includes a mixing chamber that receives separate streams of raw material and cullet mix and discharges a combined stream. The mixing chamber tapers from an inlet end to an outlet end. One inlet in the inlet end is configured to receive one of the material and mix and is aligned with an outlet in the outlet end along a vertical axis. Another inlet is configured to receive the other of the material and mix and is offset from the outlet relative to the vertical axis such the material or mix is deposited on a sidewall of the tapered chamber before reaching the outlet. A charger receives the combined stream from the mixing chamber and discharges the mixture into a molten bath in a furnace. A duct system may be used to mix exhaust from the furnace with exhaust from the mixing chamber and charger.

  • Patent number: 10807897
    Abstract: An apparatus for refining molten glass that includes a housing having a vertically oriented longitudinal axis and a transverse axis perpendicular to the longitudinal axis. Molten glass is received at an upper end of the housing and is discharged from a lower end of the housing. A guide extends at least partway across the housing and directs molten glass in a generally downward direction through the housing and in a parallel or oblique direction relative to the transverse axis of the housing.

  • Patent number: 10101090
    Abstract: A furnace system includes a furnace and a preheater configured to preheat material before it enters the furnace. The system further includes a duct system including a mixing chamber disposed between the furnace and preheater. The duct system further includes an exhaust duct in fluid communication with an exhaust fluid outlet of the furnace and configured to vent fluid exhausted from the furnace. The exhaust duct is in fluid communication with the mixing chamber and configured to redirect a portion of the fluid exhausted from the furnace to the mixing chamber. The duct system further includes a preheater duct in fluid communication with the mixing chamber and a fluid inlet of the preheater and configured to direct fluid from the mixing chamber to the preheater. The system further includes a duct scraper configured for movement within the mixing chamber to move particulates from the mixing chamber into the exhaust duct.
