    摘要: In a gas turbine having a compressor discharge casing, a cooling circuit diverts compressor discharge air toward a high pressure packing (HPP) circuit. The cooling circuit includes an inlet pipe that receives compressor discharge air. One or several cooled cooling air pipes are in fluid communication with the inlet pipe via a pipe manifold, which distributes the discharge air across the cooled cooling air pipes. A seal is disposed upstream of an entrance to the HPP circuit to limit flow into the HPP circuit, and a second seal is disposed downstream of the HPP circuit at turbine wheelspace to limit ingestion and thus the purge flow air required. The circuit serves to reduce required purge flow in the HPP circuit so that an amount of compressor discharge air can be put back to the main flow path, thereby improving turbine performance.

    摘要: A seal assembly for a rotary machine is provided. The seal assembly includes multiple sealing device segments disposed intermediate to a stationary housing and a rotor. Each of the segments includes at least one plate and a sealing element. The seal assembly also includes multiple inter-segment gaps formed between the multiple sealing device segments. Further, for each pair of adjacent sealing device segments, at least one pair of adjacent plates includes one plate overlapping another plate at an inter-segment gap.

    摘要: The embodiments described herein provide a cloth seal for use with turbine components. The cloth seal includes first and second cloth layers. One or more central shims are positioned between the first and second cloth layers so as to block a leakage flow path. Another shim is positioned on and seals the opposite side of the first cloth layer from the one or more central shims positioned between the first and second cloth layers so as to block another leakage flow path. Yet another sealing shim may be positioned on the opposite side of the second cloth layer from the one or more central shims positioned between the first and second cloth layers to as to seal the opposite side of the second cloth layer and block another leakage flow path.

    摘要: The present application thus provides a retractable seal system for use between a high pressure side and a low pressure side of a turbine engine. The retractable seal system may include a seal positioned in a slot of a stationary component, a pressure balance pocket positioned about the seal, and a conduit in communication with the pressure balance pocket and the high pressure side.
