    Abstract: An aluminum reduction cell having a shell structure with a pair of longitudinally extending sidewalls, a pair of transversely extending endwalls, a bottom wall, and an open top having an upper edge. The aluminum reduction cell also has a transverse support structure with transverse bottom beams located under the shell structure and extending transversely between the sidewalls, each of the transverse bottom beams having a pair of opposed ends. The aluminium reduction cell also has compliant binding elements fixed to the transverse support structure, each extending vertically along an outer surface of one of the sidewalls for applying an inwardly directed force said sidewall. The compliant binding elements are in the form of cantilever springs. Each spring has a metal member with a lower end which is secured to the transverse support structure, and a compliant, upper free end which is movable inwardly and outwardly in response to expansion and contraction of the shell structure.

    Abstract: A highly flexible sealing arrangement designed to seal high-temperature furnace ports, particularly the electrode port of an electric furnace. The seal comprises an annular support member fixed to a flexible sealing member and employs the use of a garter spring to uniformly apply the desired amount of seal compression. The arrangement and flexibility of the sealing member allows the seal to adapt itself to the wide range of operating and upset conditions that typically exist for a furnace electrode seal. Frictional wear on the seal may be greatly reduced as the design inherently allows for a much lower amount of seal compression to be applied, furthermore, the seal is able to move axially which can significantly reduce wear caused by electrode regulation.

    Abstract: A chill mold is used to cool molten material to form a casting. A support holds the chill mold so that a bottom of the chill mold is elevated. A baffle is arranged to divert a generally horizontal flow of cooling air upwardly to impinge the bottom of the chill mold. A plurality of chill molds may be aligned generally in a row, and at least one fan may be arranged at an end of the row to direct the flow of cooling air underneath the chill molds. The size and the vertical position of the baffles may be varied along the row, so as to generally equalize convective cooling rates among the chill molds in the row.

    Abstract: A burner is provided for a pulverous feed material. The burner has a structure that integrates the burner with a reaction vessel, and has an opening that communicates with the interior of the reaction vessel. The burner also has a gas supply channel to supply reaction gas through the opening into the reaction vessel, and a feed supply for delivering pulverous material to the reaction vessel. The burner also has a fluidic control system having at least one port capable of directing a stream of fluid at an angle to the direction of flow of the reaction gas so as to modify the flow of the reaction gas. In addition, components are provided to modify the swirl intensity and turbulence intensity of the reaction gas independently of the exit velocity.

    Abstract: A methanol indirect combustion combined-cycle power generation apparatus and method. A liquid methanol input stream is evaporated to provide a gaseous methanol stream which is converted to syngas that is combusted in a gas turbine assembly to drive a first electrical generator and produce an exhaust gas. Heat from the exhaust gas of the gas turbine assembly is used to produce first and second steam streams. The first steam stream drives a first steam turbine and provides the heat required for converting the gaseous methanol stream to the syngas combustion stream. The second steam stream drives a second steam turbine and provides the heat required for evaporating the liquid methanol input stream. A second electrical generator is driven using at least one of the first and second steam turbines.

    Abstract: A method for removing elemental sulfur from a hot gas stream, such as an autoclave vent gas, while simultaneously cooling the gas stream. The method results in conversion of sulfur in the hot gas stream to the form of solid, non-sticky sulfur allotropes such as rhombic sulfur while avoiding formation of sticky sulfur allotropes such as monoclinic sulfur, thereby avoiding scaling and fouling of plant equipment. According the method, the hot gas stream is contacted with an aqueous medium containing a particulate material inside a quench vessel having a first inlet for the hot gas stream, a second inlet for the aqueous medium, and an outlet for removing a sulfur-containing liquid fraction from the vessel. At least a portion of the sulfur contained in the hot gas stream, along with other condensable materials, becomes incorporated into the aqueous medium and is subsequently drained from the vessel. The aqueous medium may comprise a slurry of tailings or other waste material, and the particulate matter contained in the aqueous medium may provide nucleation sites for the preferential formation of non-sticky solid forms of sulfur.
