  • Aluminum furnace and preheater therefor
    Patent number: 4439145
    Abstract: A reverberatory furnace for melting aluminum or other metals which includes a preheater (12) which utilizes exhaust flue gasses from the furnace (10) to preheat the metal before it enters the furnace. A set of horizontal flue ducts (18, 20, 22) conduct the flue gasses to a preheater chamber (26) where they heat the metal. An air entrance port (50) is provided in the preheater chamber (26) to allow secondary combustion of the volatile flue gasses for additional efficiency.
