Abstract:
A turbine for use in a power generation system, said turbine comprising:a) a stator; b) a rotor generally coaxially aligned with said stator and radially spaced apart from said stator to define a gap between said stator and said rotor; and c) a brush seal comprising a) a bristle holder attachable to said stator; and b) a plurality of yarns, each of said yarns consisting essentially of a multiplicity of filaments, each of said filaments defining a bristle, each of said bristles consisting essentially of an aramid filament and secured to said bristle holder, wherein each of said bristles has a diameter of less than 0.001 inch, said bristles having a packing density of greater than 100,000 filaments per inch, and wherein said brush seal reduces leakage of a fluid across a pressure drop in said turbine, said fluid disposed in said gap and having said pressure drop generally transverse to said gap, said pressure drop generated during operation of said turbine.
