摘要： In a steam turbine, a combined brush and labyrinth seal is provided between a diaphragm web and a sealing surface on a rotatable component radially outwardly of the rotor surface. The contact between the brush seal and sealing surface lies along an axially upstream projecting flange of an annular platform such that heat generated by frictional contact between the bristles and the sealing surface has minimal effect on the rotor surface and hence rotor dynamics. A backup labyrinth seal is provided between the web and platform. Additionally, axially upstream projecting flanges are provided on the downstream buckets and which flanges are spaced radially outwardly of the rotor surface and lie in registration with the diaphragm web. Labyrinth teeth seal between the diaphragm web and the bucket flanges serving as a backup seal.

摘要： A brush seal is provided between static components of a turbine. The turbine flowpath has an inlet spaced from another the inner web of the first stage nozzle. A brush seal is disposed between the two static components to minimize leakage flow to the packing casing region. The bristles of the brush seal are preloaded to fill any gap between the static components caused by distortion or out-of-roundness of the opposed surfaces being sealed. A side plate may contact the opposed sealing surface, increasing the pressure capability of the brush seal and minimizing overall seal leakage by providing the minimum possible flow area restricted solely by the bristles.
