A sealing valve arrangement for a shaft furnace charging installation, said arrangement comprising: a shutter arranged for cooperating with a valve seat; an integrated dual-motion shutter-actuating device for moving said shutter between a sealed closed position in sealing contact with the valve seat and an open position remote from the valve seat, said integrated dual-motion shutter-actuating device comprising: a primary motion assembly for moving said shutter from said sealed closed position to an undamped position wherein the shutter is released from the valve seat; a secondary motion assembly for tilting said shutter from said undamped position to said open position remote from the valve seat, said secondary motion assembly comprising a tilting arm carrying said shutter and connected to a tilting shaft that defines an axis of rotation and a tilting shaft actuator configured to impart an angular rotation about said axis to said tilting arm; wherein said integrated dual-motion shutter-actuating device further comprises a stationary outer cylindrical sleeve, wherein said primary motion assembly comprises an inner eccentric sleeve shaft rotationally mounted within said outer cylindrical sleeve and a primary motion actuator configured to impart angular rotation to said inner eccentric sleeve shaft, the primary motion being a function of the eccentricity and angular rotation of the inner eccentric sleeve shaft; and wherein said tilting shaft of said secondary motion assembly is rotationally mounted within said inner eccentric sleeve shaft of said primary motion assembly, the secondary motion being a function of the angular rotation of the tilting shaft.

A combustor for a gas turbine engine includes a support shell; a first liner panel mounted to the support shell via a multiple of studs, the first liner panel including a first rail that extends from a cold side of the first liner panel such that the rail is non-perpendicular to the cold side and includes a concave surface to at least partially form a curved interface passage; and a second liner panel mounted to the support shell via a multiple of studs, the first liner panel including a second rail that extends from a cold side of the second liner panel and includes a convex surface to at least partially form the curved interface passage.

Provided is a decompression heat-insulating pipe structure that can be used in the system operating at high temperatures. A decompression heat-insulating pipe structure of the present disclosure includes: an outer tube and an inner tube each having a flange; and a seal member between the flanges, the seal member being configured to keep a space between the outer tube and the inner tube in a decompression state, and a shifting means configured to shift the outer tube and the inner tube relatively so as to selectively dispose the tubes at a pressing position to press the seal member between the flanges and at a cancellation position to cancel the pressing of the seal member.

A decompression heat-insulating pipe structure that can exhibit the desired heat-insulating performance and is easy to assemble. In the structure, a space between ends of inner and outer tubes is decompressed. The outer tube includes a first flange, which extends radially inward from an axially one end thereof, and a second flange, which extends radially outward from the axially other end thereof. The inner tube includes a third flange, which extends radially inward from an axially one end thereof and is opposed to the first flange at an axially inward position of the first flange, and a fourth flange, which extends radially outward from the axially other end thereof and being opposed to the second flange at an axially outward position of the second flange. First and second elastic seal members are disposed between the first and third flanges and between the second and fourth flanges, respectively.

The present invention relates generally to furnace systems and more particularly, but not by way of limitation, to a split-ring assembly for sealing a junction between a catalyst tube and a furnace. In one aspect, the present invention relates to a ring-seal assembly. The ring-seal assembly includes a housing ring coupled to an outer surface of a furnace. The housing ring is disposed around a circumference of a tube proximate a junction with the furnace. The ring seal assembly further includes a brush seal that is at least partially disposed within the housing ring. The brush seal is disposed around the circumference of the tube. A plurality of brushes extend radially inwardly from the brush seal towards the tube.

Provided is an arrangement for sealing a bellows cylinder in a pressure block of a pressure ring assembly. The bellows cylinder is located in a cavity formed in the pressure block and is operated by hydraulic fluid to give pressure against a contact shoe of a contact shoe ring arranged on the inside of the pressure ring assembly. The bellows cylinder is sealed to the cavity. A sealing bowl is arranged on the bellows on the inner side of the pressure block. The sealing bowl has an essentially flat surface towards the contact shoe and is provided with a side edge extending into the cavity. A circumferential groove containing a gasket ring is on the side wall of the cavity. A flexible sealing ring is arranged around the gasket ring to give tension and pressure on the gasket ring against the side edge of the sealing bowl.

A milling apparatus for mounting and moving curtains that contain scale, water and/or other debris within a hood structure. The hood structure can form a housing that contains fixed metal curtains and/or movable metal curtains. The movable metal curtain can include a cartridge attached to the movable metal curtain. The cartridge can be attached to the movable metal curtain. The cartridge can be attached to and/or mounted on or with respect to a support, such as a support structure mounted and/or fixed with respect to the housing. A lock can be used to selectively secure the position of the cartridge with respect to the support.

A sliding style furnace cap features a furnace tube cap and a slider. The furnace tube cap has a first cap portion to couple to a furnace tube of a furnace, and a second cap portion with a bearing assembly arrangement. The furnace tube cap also has an inner tube cap channel passing through it with an inner tube cap channel sealing arrangement configured to extend outside the inner tube cap channel. The slider has an orifice/channel configured therein passing through the slider, couples and slides in the bearing assembly arrangement from an inject position to a rinse position, and vice versa, has a cam-like contoured surface with a first ramp configured to couple a first raised surface and an intermediate lower surface, and with a second ramp configured to couple the intermediate lower surface to a second raised surface. The slider also moves towards the inner tube cap channel and causes the bearing assembly arrangement to force a part/side of the slider to push against the inner channel sealing arrangement as part of the roller bearing arrangement rides up either the first ramp to the first raised portion when the slider is moved to the inject position, or the second ramp to the second raised portion when the slider is moved to the rinse position, and the first part of slider configured to seal the inner tube cap channel sealing arrangement when the slider is in either the inject position or the rinse position. The slider also moves away from the inner tube cap channel and causes the bearing assembly arrangement to allow the part/side of the slider to float above the inner channel sealing arrangement as the part of the roller bearing assembly rides along the intermediate lower surface when the slider is in transition between the inject position and the rinse position.
