  • Continuous furnace
    Patent number: 6116894
    Abstract: A continuous furnace for baking ceramic molded parts has a heating area (14), a baking area (16) and a cooling area (18). At least one smoke gas duct (22) extends from the heating area (14) into a combustion chamber (24) and at least one hot air duct (28) leads back from the combustion chamber (24) to the heating area (14). Hot air loaded with binder fractions is extracted from the heating area at one or several spots. The combustion gases are then led into a combustion chamber where they are burned, so that a largely purified hot air may then be led back to the heating area.
