  • Regenerator flow distribution by means of a burner
    Patent number: 4375235
    Abstract: In a regenerative furnace of the type used for melting glass, localized overheating of the regenerator packing is minimized, heating of the regenerator packing is made more uniform, and regenerator efficiency is improved by employing a gas stream, preferably a high velocity burner, in the plenum of the regenerator to control gas flow distribution within the regenerator.
    Type: Grant

  • Regenerator flow distribution by means of air jets
    Patent number: 4375236
    Abstract: In a regenerative furnace of the type used for melting glass, localized overheating of the regenerator packing is minimized, heating of the regenerator packing is made more uniform, and regenerator efficiency is improved by employing air jets in the space alongside the regenerator packing opposite the flue to counteract flow imbalances in the regenerator.
