A method and seal assembly for sealing a rotary machine including a rotary component and a stationary component is provided. The method includes providing a plurality of flexible leaf plates in an opening defined between a pair of spaced walls that include an adjustable front wall and an adjustable back wall that is opposed to the front wall. The method also includes adjusting a width of the opening by axially adjusting at least one of the front and back walls with respect to a central rotational axis of the rotary component.
摘要:
A method of retrofitting a gas turbine wherein the gas turbine comprises a stator and a rotor. The rotor is coaxially aligned with the stator and spaced apart from the stator so as to define a gap therebetween. The method of retrofitting comprises fixedly securing a sealing member to the stator. The sealing member is configured to restrict a flow of a fluid medium in a fluid path across the gap and generate a pressure drop generally transverse to the gap during operation of the gas turbine.
