    摘要： A calcining kettle includes an outer kettle shell, an inner kettle shell, an interior heat exchanger assembly defining at least one tortuous path inside a volume defined by the inner kettle shell, and an agitator within the inner kettle shell. The inner kettle shell is disposed within the outer kettle shell such that the inner kettle shell and the outer kettle shell together at least partially define a jacket adjacent the inner kettle shell. The inner kettle shell and the interior heat exchanger assembly at least partially define a processing volume. The agitator is configured to rotate at least one paddle to cause movement of a feedstock material within the processing volume. A heating device may be structured and adapted to circulate a heat transfer fluid in the at least one tortuous path and the jacket. Calcining methods are also disclosed.

    摘要： A stave comprising an outer housing, an inner pipe circuit comprising individual pipes housed within the outer housing, wherein the individual pipes each has an inlet end and an outlet end and wherein each pipe may or may not be mechanically connected to another pipe, and a manifold, integral with or disposed on or in the housing; wherein the inlet and/or outlet ends of each individual pipe is disposed in or housed by the manifold. The manifold may be made of carbon steel while the housing may be made of copper. Each of the inlet and outlet ends of each individual pipe may be surrounded in part by cast copper within a housing of the manifold.

    摘要： A raku kiln has a fire ring with a cylindrical sidewall and bottom made of refractory material with a kiln shelf supported a few inches above the bottom to enclose a space that is superheated by burners. A firing-chamber rests on the fire ring and is lifted by a two aligned pulleys on top of a pole which rotates to move the chamber out of the way. A vertical pole mates with tubes on the chamber for vertical guidance during raising and lowering of the chamber. Flanges on the lower end of the chamber allow adding an extension chamber.

    摘要： A metallurgical shaft furnace for producing metal from a charge which enhances the preheating capacity of upwardly flowing gases in an upper preheating portion of the furnace, the upper portion being formed from concentric sections which increase in diameter from the uppermost section to the lowermost section of the preheating portion of the furnace. Troughs are formed where adjacent sections meet to form cooling rings around the upper portion, the rings projecting inwardly from the furnace wall. The lower portion comprises a melting portion having tuyeres, a hearth and tap means. Vertical cooling conduits may be provided in the lower section with conduits adjacent each tuyere terminating above the tuyere to prevent damage to the conduits.

    摘要： A heat treatment apparatus includes: a furnace core tube made of silica glass; a heater provided adjacent to the furnace core tube, the heater heating a heating region; and a moving mechanism supporting a porous glass base material and relatively moving the porous glass base material with respect to the heater in the furnace core tube in a state where the heating region is heated by the heater to make the porous glass base material pass through the heating region. The heat treatment apparatus includes a thin-walled part provided in a region adjacent to a portion located in the heating region in the furnace core tube, the thin-walled part having a thickness of glass less than that of the portion located in the heating region.

    摘要： A vacuum oven or vacuum furnace is disclosed having a heat distribution sleeve that conforms to the shape of an interior heating chamber. The heat distribution sleeve may be of generally annular shape, like a ring, and located in a substantially regularly spaced and offset relationship from a heating element located within walls adjacent the interior heating chamber. The heat distribution sleeve includes a thermal conductive material which absorbs and re-radiates heat emitted from the heating element, thereby providing more consistent and regular radiation fields for heating treating a work piece that is loaded on a work holding tray and, upon the vacuum oven being in an operational position, the work piece is located within the furnace chamber.
