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: An uptake apparatus is arranged to extract a stream of off-gas containing carbon monoxide from a process vessel. At least one gas conditioning train receives and conditions the stream. An outlet expels at least a portion of the stream. A portion of the stream is separated to form a recycle stream. An eductor apparatus combines the stream with the recycle stream, to decrease the temperature and increase the static pressure of the stream. The stream is maintained at a positive gauge pressure.

Abstract: An apparatus connects first and second conduits that convey a flow of gas. The apparatus includes a first flange element fixed to the first conduit, and a second flange element fixed to the second conduit. The flange elements are coupled together to permit fluid communication in an internal environment between the first and second conduits. At least one port is intermediate the flange elements to deliver a flow of purge gas therebetween. The at least one port may be located within a purge gas channel arranged in one of the flange elements. A pressure gradient of the flow of purge gas may substantially prevent at least one of fluid egress from the internal environment and fluid ingress from an external environment. Purge gas distribution systems and related methods are also described.

Abstract: A chute receives contaminant gas-laden dust from a dust collector. At least one gas injector provides an upward flow of purge gas in the chute to release contaminant gas entrained with the dust. Downstream areas are maintained at positive pressure relative to upstream areas. A purge hopper arranged below the chute collects the dust. Dust handling apparatuses allow the upward flow of the purge and contaminant gases. Movable flaps in the dust handling apparatuses include perforations that may be capped to vary the gas flow rate. A dust discharge apparatus discharges washed dust from the purge hopper.
