A rotary seal assembly for a rotary kiln having a hood and a rotary drum with an opening formed between the drum and the hood, and an end. The rotary seal assembly includes a flexible framework arrangement that attaches to the end. The rotary seal assembly includes a riding surface that engages the drum as the drum rotates. The riding surface includes a series of seal segments with each seal segment having a mounting eye positioned to eliminate a fulcrum point at the mounting eye. The rotary seal assembly includes a seal that is supported by the riding surface and is in essentially 360-degree contact with the drum when it is rotating and seals the opening between the drum when it is rotating in the hood to prevent fluid flow into and out of the end. A rotary seal assembly for a rotary kiln having a hood and a rotary drum with an opening formed between the drum and the hood, and an end, includes redundant tension springs which form a complete 360-degree circle around the drum. A method for sealing an opening formed between a drum and a hood.

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.

Systems and methods for processing a waste stream for feeding into a thermal unit performing an airless or oxygen starved incineration process like pyrolysis. Embodiments comprise an inlet hopper for receiving a waste stream, an inlet hopper lid, a slide gate that when closed forms the base of the inlet hopper and when open allows the waste stream to pass into an intermediate hopper, a ram body that when closed forms the base of the intermediate hopper and when open allows the waste stream to pass into a ram cylinder, a crusher plate on the front face of the ram body, a ram for driving the ram body and its crusher plate forward into the waste within the cylinder, a compactor cone comprising teeth for splitting, and an outlet through which the crushed and split waste stream exits the system into a thermal unit.

A furnace system has a furnace-tube-cap (FTC) and a slider. The FTC has a first-cap-portion coupled to a furnace tube of a furnace, a second-cap-portion with a bearing-assembly-arrangement (BAA), and an inner-tube-cap-channel (ITCC) passing from the first-to-second cap portion with an ITCC sealing arrangement extending outside the ITCC. The slider slides in the BAA to/from inject-and-rinse positions, and has a first-ramp (FR), a first-raised-surface (FRS), an intermediate-lower-surface (ILS), a second-ramp (SR), and a second-raised-surface (SRS). When the slider moves to the inject-or-rinse positions, the BAA forces a slider-part to push against an inner-channel-sealing-arrangement (ICSA) as the BAA goes from the FR-to-FRS, or the SR-to-SRS. When the slider is in the inject-or-rinse position, a first-slider-part seals the ITCC sealing arrangement. When the slider transitions between the inject-and-rinse positions and the BAA rides along the ILS, the BAA allows the slider-part to float above the ICSA arrangement.

A fluid cooled housing system for use in metal making furnaces. In particular, the present invention related to a novel and inventive housing and guard member configured to receive and protect an implement, such as a burner or a lance, used in connection with metal making furnaces. A preferred embodiment of the present invention comprises a housing comprising an outer shell and an inner shell that define a fluid chamber, an end cap, a bushing insert, a face plate, a fluid inlet, and a fluid outlet. Both the fluid inlet and the fluid outlet are preferably in fluid communication with both the fluid chamber defined by the shells and a fluid chamber defined by the bushing insert. In alternative preferred embodiments, the housing system further comprises a guard member that preferably envelopes and further protects the fluid cooled housing.

A continuous annealing furnace for annealing steel strips has a reaction chamber wherein the steel strips are transported vertically, the reaction chamber having openings supplied with a reactant, also called reactant openings, located at the top or at the bottom of the reaction chamber, wherein the reaction chamber further has other openings supplied with an inert gas, also called inert gas openings, the inert gas openings being located on the lateral sides of the reaction chamber.

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 invention relates to a slide valve (20) having a slide valve plate (32) movable in a slide valve rail (29) between a locked position and an open position in a slide valve casing (26), said slide valve rail (29) being provided with a slide valve seal for attaining a gas-proof locked position, said slide valve rail (29) being connected to the slide valve casing (26) via a flange connection in such a manner that the slide valve rail (29) is removable from the slide valve casing (26) radially to a flow axis of the slide valve (20).

A rotary bed-type electric furnace includes a rotary bed configured to carry material, and a rotator configured to rotate the rotary bed so that material carried on the rotary bed passes through peripheral zones of the rotary bed-type electric furnace. The peripheral zones include a feeding zone configured to receive material on the rotary bed, a drying zone configured to dry and heat material by means of electrical energy, a heating zone configured to heat material by means of electrical energy, a cooling zone configured to lower the temperature of the material and configured to release gases from the material, and a discharging zone configured to discharge material from the rotary bed of the furnace.
