Abstract: A separator for separating water from a mixture of water and steam in which an elongated, outer, water scroll is concentrically spaced from an elongated, inner, steam scroll. One longitudinal edge of each scroll is connected to a girth baffle disposed adjacent the side of a steam drum, and both scrolls extend through semi-circular curves of 180.degree. in cross section. The steam scroll is covered through the first 90.degree. of its curve, and is provided with a longitudinally-elongated opening extending circumferentially the second 90.degree. of its curve. A perforated plate encloses the bottom of the steam scroll to form a longitudinal flow passage. The centrifugal action imparted by the 180.degree. curvature of the separator causes the water to sepate from the steam-water mixture introduced between the steam and water scrolls, to flow along the inner surface of the water scroll, and to discharge downwardly through perforated, water splash diffuser plates.

Abstract: A steam and water drum internal arrangement which provides free access to the drum inner wall and facilitates the removal of the steam and water separators from within the drum by mounting the separators on a duct which extends centrally of the drum and communicates with extension conduits to receive a steam and water mixture from the steam generating tubes.

Abstract: A cyclone separator having a central fluid conduit. An interceptor ring is externally attached to the end of the fluid conduit and has a surface which intercepts fluid flowing longitudinally along the outer surface of the fluid conduit and directs the fluid outwardly toward the interior wall of the container. Circumferential and longitudinal slots are located in the container in proximity to the interceptor ring to enhance the outward direction flow of fluid from the ring. A diffuser collar having a central opening therein is connected to the interceptor ring in a manner leaving an annular space or circumferential slots between the ring and the collar through which space unwanted materials.In an alternate version the diffuser collar is larger in diameter than the fluid conduit and the conduit extends into the diffuser collar forming a space therebetween by which an outer layer of fluid is skimmed from the spiraling column of fluid entering the fluid conduit to further cleanse the fluid of unwanted substances.

Abstract: A device for supporting an apparatus subject to high temperature differentials causing vertical as well as horizontal expansions.The device comprises a support for supporting one side of the apparatus for relative movement while the opposite side of the apparatus is connected to a fixed support. The side providing for relative movement comprises a support having a support means to provide for vertical and horizontal expansion to maintain the apparatus in horizontal alignment. The support means provides for expansion movement at an angle substantially equal to an angle whose tangent can be determined by the vertical and horizontal expansion forces acting on the apparatus and its supporting structure. The device is suited for cyclone separators supported within high temperature process vessels where one side of the support for the cyclone separator is fixed to the cyclone and the other side is fixed to a beam.

Abstract: A cluster of closely spaced cyclones are arranged with their axes in parallel spaced relation, and cylindrical portions of the cyclones form rigid connections between parallel walls which define a chamber for directing fluid into corresponding tangential inlets within the cyclones. In one embodiment, the walls are formed by flanges molded as integral parts of the plastic cyclone bodies, and the flanges are interconnected by key members. In another embodiment, the walls are formed by flat plates which are rigidly connected by independently removable molded plastic bodies having integral threads. Each of the cyclones includes a replaceable apex cone section which may be ceramic and has an externally threaded portion projecting into an apex discharge chamber defined between an inner wall and a parallel spaced transparent outer wall.

Abstract: An improvement in a regenerator which incorporates an external plenum on the exterior of the regenerator apparatus for receiving and collecting the flue gases separated from regenerated catalyst by a plurality of cyclone separators or other separating apparatus is disclosed. The external plenum communicates by means of stand pipes through the wall of the regenerator. This supports the cyclone separators or other separating means mechanically and avoids certain thermal stresses which would otherwise occur in the plenum if it were placed on the interior of the regeneration chamber.
