Title: Method and system to facilitate sealing in gas turbines

Abstract

A method and system for sealing between components within a gas turbine is provided. A first recess defined in a first component receives a seal member. A second recess defined in a second component adjacent the first component also receives the seal member. The first and second recesses are located proximate a hot gas path defined through the gas turbine, and define circumferential paths about the turbine axis. The seal member includes a sealing face that extends in a direction substantially parallel to the turbine axis. The seal member also includes a plurality of seal layers, wherein at least one of the seal layers includes at least one stress relief region for facilitating flexing of the first seal member.

  • This patent describes a method of sealing a leaking valve on a compressed gas tank for safe transport of the tank and valve to a repair depot. It comprises: placing a cap over the valve and attaching the cap to the tank, filling the cap through a fill opening with a fusible substance in liquified form, venting the cap via a vent opening during filling, sealing off the fill and vent openings, causing the fusible substance to solidify within the cap and around the valve to encapsulate the valve in the solidified fusible substance, transporting the tank and valve withmore » the associated cap and solidified fusible substance to a repair depot, at the repair depot, liquefying the fusible substance and draining it from the cap, and removing the cap from the tank to accommodate access to and servicing of the valve.« less
  • Systems, components, and methods relating to subterranean containment barriers. Laterally adjacent tubular casings having male interlock structures and multiple female interlock structures defining recesses for receiving a male interlock structure are used to create subterranean barriers for containing and treating buried waste and its effluents. The multiple female interlock structures enable the barriers to be varied around subsurface objects and to form barrier sidewalls. The barrier may be used for treating and monitoring a zone of interest.
  • This patent describes a fluidized bed combustion system. It comprises: separating means for receiving a mixture of flue gages and entrained particulate material from fluidized bed and separating the entrained particulate material from the flue gases, means for passing the separated flue gases from the separating means to a heat recovery unit, a seal vessel, a dipleg for passing the separated material from the separating means to the seal vessel, means for passing the separated material from the seal vessel back to the fluidized bed, and means for introducing air or gas to the seal vessel for fluidizing the separatedmore » material in the seal vessel to seal against the backflow of the separated material from the fluidized bed, through the dipleg and back to the separating means. The air introducing means comprises a first conduit for introducing air or gas into the seal vessel in a path aligned with the flow path of the separated material from the dipleg, and a second conduit for introducing air or gas into an area of the seal vessel surrounding the flow path of air or gas from the first conduit.« less
  • An improvement to a sealing system for restricting fluid flow around a piston rod between a piston cylinder and crankshaft space in a hot gas engine where a seal element is secured around the piston rod in an intermediate chamber, the improvement including a link in the crankshaft space connecting, and permitting relative radial motion between, the piston rod and the crosshead and an o-ring having a diameter substantially greater than that of the piston rod and being secured between a lower ring securing the seal element in place around the piston rod and a wall of the intermediate chambermore » for frictionally restricting radial movement of the lower ring.« less
